    ABSTRACT

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the coronavirus disease 2019 (COVID-19), is still circulating among humans, leading to the continuous evolution. SARS-CoV-2 Omicron JN.1 evolved from a distinct SARS-CoV-2 lineage, BA.2.86, spread rapidly worldwide. It is unclear why BA.2.86 did not become dominant and was quickly replaced by JN.1, which possesses one amino acid substitution in the spike protein (S:L455S) and two in the non-spike proteins NSP6 and ORF7b (NSP6:R252K and ORF7b:F19L) compared to BA.2.86. Here, we utilized recombinant viruses to elucidate the impact of these mutations on the virological characteristics of JN.1. We found that the mutation in the spike attenuated viral replication, but the non-spike mutations enhanced replication, suggesting the mutations in the non-spike proteins compensate for the one in the spike to improve viral fitness, as the mutations in the spike contribute to further immune evasion. Our findings suggest that functional changes in both the spike and non-spike proteins are necessary in the evolution of SARS-CoV-2 to enable evasion of adaptive immunity within the human population while sustaining replication.

    IMPORTANCE

    Because the spike protein is strongly associated with certain virological properties of SARS-CoV-2, such as immune evasion and infectivity, most previous studies on SARS-CoV-2 variants have focused on spike protein mutations. However, the non-spike proteins also contribute to infectivity, as observed throughout the evolution of Omicron subvariants. In this study, we demonstrate a “trade-off” strategy in SARS-CoV-2 Omicron JN.1 in which the reduced infectivity caused by spike mutation is compensated by non-spike mutations. Our results provide insight into the evolutionary scenario of the emerging virus in the human population.

    英語, 研究論文(学術雑誌), Mesothelioma is a highly aggressive tumor affecting an increasing number of patients worldwide. Owing to the poor clinical outcomes associated with current therapies, the development of novel therapies that target cancer stem cells (CSCs) is desirable. Here, we examined the applicability of our previously established hydrogel-based rapid CSC generation method to human mesothelioma cell lines and further analyzed the characteristics of the induced mesothelioma stem cell (MesoSC) -like cells. Human mesothelioma cell lines cultured on hydrogels presented increased expression of pan-stem cell markers and acquired spheroid formation and early tumorigenicity, suggesting that MesoSC-like cells are highly malignant. Microarray analysis demonstrated that the expression of SLC13A5, a citrate transporter involved in TCA cycle, was significantly induced in the resulting MesoSC-like cells. The overexpression of SLC13A5 resulted in a metabolic shift toward oxidative phosphorylation, increased phosphorylation of ERK and YAP, and increased SOX2 expression, leading to increased cisplatin resistance. scRNA-seq database analysis revealed that clinical mesothelioma samples contained a small number of SLC13A5-expressing cells. Our findings suggest that the hydrogel-based CSC generation method is also effective for human mesothelioma cells and that SLC13A5 may contribute to MesoSC survival. The new properties of MesoSCs revealed in this study may provide clues for establishing future treatments.

    英語, 研究論文(学術雑誌), Parkinson's disease (PD) is a neurodegenerative disease primarily affecting the central nervous system and impacting both the motor system and non-motor systems. Although administration of L-DOPA is effective, it is not a fundamental treatment and has side effects such as diurnal fluctuation and dyskinesia, highlighting the need for new treatment methods. There is a growing interest in dopaminergic neuron transplantation as a potential treatment. Dopaminergic neurons derived from pluripotent stem (iPS) cells provide a valuable source for transplantation therapies. Developing an efficient method to differentiate iPS cells into dopaminergic cells is essential for cell transplantation therapy. While Cell differentiation is typically controlled by the addition of specific reagents, the physical characteristics of culture substrate, especially in the charge and stiffness, are also crucial factors in regulating differentiation. In this research, we show that two newly developed electrically charged polymeric hydrogels composed of cationic (C) and anionic (A) monomers inratio of 1-9 and 2 to 8 can significantly promote Dopaminergic neuron differentiation. Our findings emphasize the importance of culture substrates in effective dopaminergic cell differentiation.

    研究論文(学術雑誌), Abstract

    Recent studies suggest that lung adenocarcinoma cells are closely associated with the tumorigenesis of large‐cell neuroendocrine carcinoma via cellular transformation. However, morphological evidence, along with genetic abnormalities before, during, and after transformation, is quite limited. We present here a case of combined large‐cell neuroendocrine carcinoma and adenocarcinoma exhibiting acinar and solid patterns. Adenocarcinoma cells with abundant mucin, exhibiting positivity for both napsin‐A and neuroendocrine markers, were partially found in the acinar adenocarcinoma component and extensively observed in the solid adenocarcinoma component. Next‐generation sequencing using extracted genomic DNA from the three components revealed homozygous TP53 (missense) and STK11 (nonsense) mutations in all three components, suggesting monoclonal origin. Furthermore, MYC gene amplification, recently presumed to be a pivotal driver in neuroendocrine transformation, was observed in both the solid adenocarcinoma and large‐cell neuroendocrine carcinoma components. These genetic findings corresponded to pre‐ and post‐transformation morphology, providing compelling evidence that some kinds of adenocarcinomas may serve as a precursor of large‐cell neuroendocrine carcinoma.

    英語, 研究論文(学術雑誌), Leukemia stem cells (LSCs), capable of simultaneous self-renewal and differentiation, are resistant to chemotherapy and the cause of relapse in refractory cases of leukemia. As a method to rapidly generate LSCs has not been established, research on LSCs as therapeutic targets has been hampered. Here, we demonstrate that K562 leukemia cells acquired LSC properties with increase in stemness markers such as CD34, Oct3/4, and Nanog and metabolic alterations towards OXPHOS by culturing cells on synthetic polymer hydrogels. In this hydrogel-generated LSCs, single-cell RNA sequencing identified the increase in expression levels of AKR1B1 and TSPYL5, which play an essential role for stemness generation. Decrease in expression of CD34, Oct3/4, and Nanog were observed in K562 cells with knockdown of AKR1B1 and TSPYL5. These results indicate that cell culturing on synthetic polymer hydrogels can be a useful system to generate LSCs and AKR1B1 and TSPYL5 may become therapeutic targets for LSCs.

    英語, 研究論文(学術雑誌), Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the largest single-stranded RNA virus known to date. Its genome contains multiple accessory protein genes that act against host immune responses but are not required for progeny virus production. The functions of the accessory proteins in the viral life cycle have been examined, but their involvement in viral pathogenicity remains unclear. Here, we investigated the roles of the accessory proteins in viral immunopathogenicity. To this end, recombinant SARS-CoV-2 possessing nonsense mutations in the seven accessory protein open reading frames (ORFs) (ORF3a, ORF3b, ORF6, ORF7a, ORF8, ORF9b, and ORF10) was de novo generated using an early pandemic SARS-CoV-2 strain as a backbone. We confirmed that the resultant virus (termed ORF3-10 KO) did not express accessory proteins in infected cells and retained the desired mutations in the viral genome. In cell culture, the ORF3-10 KO virus exhibited similar virus growth kinetics as the parental virus. In hamsters, ORF3-10 KO virus infection resulted in mild weight loss and reduced viral replication in the oral cavity and lung tissue. ORF3-10 KO virus infection led to mild inflammation, indicating that an inability to evade innate immune sensing because of a lack of accessory proteins impairs virus growth in vivo and results in quick elimination from the body. Overall, we showed that SARS-CoV-2 accessory proteins are involved in immunopathogenicity.

    英語, 研究論文(学術雑誌), BACKGROUND: With the recent advent of genetic testing, IDH-mutant glioma has been found among adult brainstem gliomas. However, the clinical outcome and prognosis of IDH-mutant brainstem gliomas in adults have not been elucidated. This study aimed to investigate the clinical outcome, radiological findings, and genetic features of adult patients with IDH-mutant diffuse brainstem gliomas. METHODS: Data from adult patients with brainstem glioma at Hokkaido University Hospital between 2006 and 2022 were retrospectively analyzed. Patient characteristics, treatment methods, genetic features, and prognosis were evaluated. RESULTS: Of 12 patients with brainstem glioma with proven histopathology, 4 were identified with IDH mutation. All patients underwent local radiotherapy with 54 Gray in 27 fractions combined with chemotherapy with temozolomide. Three patients had IDH1 R132H mutation and one had IDH2 R172G mutation. The median progression-free survival and overall survival were 68.4 months and 85.2 months, respectively, longer than that for IDH-wildtype gliomas (5.6 months and 12.0 months, respectively). At the time of initial onset, contrast-enhanced lesions were observed in two of the four cases in magnetic resonance imaging. CONCLUSION: As some adult brainstem gliomas have IDH mutations, and a clearly different prognosis from those with IDH-wildtype, biopsies are proactively considered to confirm the genotype.

    英語, 研究論文(学術雑誌), Circulation of SARS-CoV-2 Omicron XBB has resulted in the emergence of XBB.1.5, a new Variant of Interest. Our phylogenetic analysis suggests that XBB.1.5 evolved from XBB.1 by acquiring the S486P spike (S) mutation, subsequent to the acquisition of a nonsense mutation in ORF8. Neutralization assays showed similar abilities of immune escape between XBB.1.5 and XBB.1. We determine the structural basis for the interaction between human ACE2 and the S protein of XBB.1.5, showing similar overall structures between the S proteins of XBB.1 and XBB.1.5. We provide the intrinsic pathogenicity of XBB.1 and XBB.1.5 in hamsters. Importantly, we find that the ORF8 nonsense mutation of XBB.1.5 resulted in impairment of MHC suppression. In vivo experiments using recombinant viruses reveal that the XBB.1.5 mutations are involved with reduced virulence of XBB.1.5. Together, our study identifies the two viral functions defined the difference between XBB.1 and XBB.1.5.

    英語, 研究論文(学術雑誌), Impaired expression of MHC (major histocompatibility complex) class I in cancers constitutes a major mechanism of immune evasion. It has been well documented that the low level of MHC class I is associated with poor prognosis and resistance to checkpoint blockade therapies. However, there is lmited approaches to specifically induce MHC class I to date. Here, we show an approach for robust and specific induction of MHC class I by targeting an MHC class I transactivator (CITA)/NLRC5, using a CRISPR/Cas9-based gene-specific system, designated TRED-I (Targeted reactivation and demethylation for MHC-I). The TRED-I system specifically recruits a demethylating enzyme and transcriptional activators on the NLRC5 promoter, driving increased MHC class I antigen presentation and accelerated CD8+ T cell activation. Introduction of the TRED-I system in an animal cancer model exhibited tumor-suppressive effects accompanied with increased infiltration and activation of CD8+ T cells. Moreover, this approach boosted the efficacy of checkpoint blockade therapy using anti-PD1 (programmed cell death protein) antibody. Therefore, targeting NLRC5 by this strategy provides an attractive therapeutic approach for cancer.

    Summary

    Monitoringin vivoviral dynamics can improve our understanding of pathogenicity and tissue tropism. For positive-sense, single-stranded RNA viruses, several studies have attempted to monitor viral kineticsin vivousing reporter genomes. The application of such recombinant viruses can be limited by challenges in accommodating bioluminescent reporter genes in the viral genome. Conventional luminescence also exhibits relatively low tissue permeability and thus less sensitivity for visualizationin vivo. Here we show that unlike NanoLuc bioluminescence, the improved method, termed AkaBLI, allows visualization of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Syrian hamsters. By successfully incorporating a codon-optimized Akaluc luciferase gene into the SARS-CoV-2 genome, we visualizedin vivoinfection, including the tissue-specific differences associated with particular variants. Additionally, we could evaluate the efficacy of neutralizing antibodies and mRNA vaccination by monitoring changes in Akaluc signals. Overall, AkaBLI is an effective technology for monitoring viral dynamics in live animals.

    英語, 研究論文(学術雑誌), OBJECTIVES: We aimed to investigate Piezo1 expression in myofibroblasts in symptomatic and asymptomatic patients undergoing carotid endarterectomy and its relationship with atherosclerotic plaque formation. METHODS: This cross-sectional study analyzed carotid plaques of 17 randomly selected patients who underwent carotid endarterectomy from May 2015 to August 2017. In total, 51 sections (the most stenotic lesion, and the sections 5-mm proximal and distal) stained with hematoxylin-eosin and elastica-Masson were examined. Immunohistochemistry was performed using antibodies to Piezo1. The Piezo1 score of a section was calculated semiquantitatively, averaged across 30 randomly selected myofibroblasts in the fibrous cap of the plaque. RESULTS: Of 17 patients (mean age: 74.2 ± 7.1 years), 15 were men, 9 had diabetes mellitus, and 13 had hypertension. Symptomatic patients had higher mean Piezo1 score than asymptomatic patients (1.78 ± 0.23 vs 1.34 ± 0.17, p < .001). Univariate linear regression analyses suggested an association between plaque rupture, thin-cap fibroatheroma and microcalcifications and the Piezo1 score (p = .001, .008, and 0.003, respectively). CONCLUSIONS: Increased Piezo1 expression of myofibroblasts may be associated with atherosclerotic carotid plaque instability. Further study is warranted to support this finding.

    英語, 研究論文(学術雑誌), The unremitting emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants necessitates ongoing control measures. Given its rapid spread, the new Omicron subvariant BA.5 requires urgent characterization. Here, we comprehensively analyzed BA.5 with the other Omicron variants BA.1, BA.2, and ancestral B.1.1. Although in vitro growth kinetics of BA.5 was comparable among the Omicron subvariants, BA.5 was much more fusogenic than BA.1 and BA.2. Airway-on-a-chip analysis showed that, among Omicron subvariants, BA.5 had enhanced ability to disrupt the respiratory epithelial and endothelial barriers. Furthermore, in our hamster model, in vivo pathogenicity of BA.5 was slightly higher than that of the other Omicron variants and less than that of ancestral B.1.1. Notably, BA.5 gains efficient virus spread compared with BA.1 and BA.2, leading to prompt immune responses. Our findings suggest that BA.5 has low pathogenicity compared with the ancestral strain but enhanced virus spread /inflammation compared with earlier Omicron subvariants.

    英語, 研究論文(学術雑誌), Uterine tumor resembling ovarian sex cord tumor (UTROSCT) is a rare tumor with low malignant potential that commonly occurs in middle age. Although more than 100 cases have been reported to date, myxoid morphology is not well documented. Here, we present a 75-yr-old woman with abnormal vaginal bleeding, with an 8-cm mass in the uterine corpus detected by irregular, high-intensity signaling on T2-weighted imaging. The uterine mass had a glistening mucinous appearance on gross examination. Microscopically, most of the tumor cells were floating in the myxoid stroma. The tumor cells formed clusters or nests with abundant cytoplasm, while some exhibited trabecular or rhabdoid appearances. Immunohistochemically, tumor cells were positive for pancytokeratin (AE1/AE3), α-smooth muscle actin, CD10, progesterone receptor, and some sex cord markers such as calretinin, inhibin, CD56, steroidogenic factor-1. Electron microscopy demonstrated epithelial and sex cord differentiation. This tumor was negative for JAZF1-JJAZ1 fusion gene that is frequently found in low-grade endometrial stromal sarcoma. Fusion genes related to UTROSCT, including NCOA2/3, were not detected by reverse transcription polymerase chain reaction. The present case suggests that UTROSCT should be included in the differential diagnosis of myxoid uterine tumors.

    英語, 研究論文(学術雑誌), In late 2022, SARS-CoV-2 Omicron subvariants have become highly diversified, and XBB is spreading rapidly around the world. Our phylogenetic analyses suggested that XBB emerged through the recombination of two cocirculating BA.2 lineages, BJ.1 and BM.1.1.1 (a progeny of BA.2.75), during the summer of 2022. XBB.1 is the variant most profoundly resistant to BA.2/5 breakthrough infection sera to date and is more fusogenic than BA.2.75. The recombination breakpoint is located in the receptor-binding domain of spike, and each region of the recombinant spike confers immune evasion and increases fusogenicity. We further provide the structural basis for the interaction between XBB.1 spike and human ACE2. Finally, the intrinsic pathogenicity of XBB.1 in male hamsters is comparable to or even lower than that of BA.2.75. Our multiscale investigation provides evidence suggesting that XBB is the first observed SARS-CoV-2 variant to increase its fitness through recombination rather than substitutions.

    英語, 研究論文(学術雑誌), In late 2022, various Omicron subvariants emerged and cocirculated worldwide. These variants convergently acquired amino acid substitutions at critical residues in the spike protein, including residues R346, K444, L452, N460, and F486. Here, we characterize the convergent evolution of Omicron subvariants and the properties of one recent lineage of concern, BQ.1.1. Our phylogenetic analysis suggests that these five substitutions are recurrently acquired, particularly in younger Omicron lineages. Epidemic dynamics modelling suggests that the five substitutions increase viral fitness, and a large proportion of the fitness variation within Omicron lineages can be explained by these substitutions. Compared to BA.5, BQ.1.1 evades breakthrough BA.2 and BA.5 infection sera more efficiently, as demonstrated by neutralization assays. The pathogenicity of BQ.1.1 in hamsters is lower than that of BA.5. Our multiscale investigations illuminate the evolutionary rules governing the convergent evolution for known Omicron lineages as of 2022.

    Cancer medicine, 12, 8, 9697, 9708, 2023年02月22日, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: Anti-angiogenic therapy with bevacizumab (BEV), an anti-VEGF antibody, plays a critical role in the treatment of ovarian cancer. However, despite an encouraging initial response, most tumors become resistant to BEV over time, and a new strategy that enables sustainable treatment using BEV is therefore needed. METHODS: To overcome the resistance to BEV in patients with ovarian cancer, we performed a validation study of combination therapy with BEV (10 mg/kg) and the CCR2 inhibitor BMS CCR2 22 (20 mg/kg) (BEV/CCR2i) using 3 consecutive patient-derived xenografts (PDXs) of immunodeficient mice. RESULTS: BEV/CCR2i demonstrated a significant effect of growth suppression in the BEV-resistant serous PDX and BEV-sensitive serous PDX compared with BEV (30.4% after the second cycle and 15.5% after the first cycle, respectively), and treatment cessation did not attenuate this effect. Tissue clearing and immunohistochemistry with an anti-α-SMA antibody suggested that BEV/CCR2i suppressed angiogenesis from the host mice more than BEV. In addition, human CD31 immunohistochemistry revealed that BEV/CCR2i decreased microvessels originating from the patients to a significantly greater degree than BEV. Regarding the BEV-resistant clear cell PDX, the effect of BEV/CCR2i was unclear during the first five cycles, but the following two cycles of increased-dose BEV/CCR2i (CCR2i 40 mg/kg) significantly suppressed tumor growth compared with BEV (28.3%) by inhibiting the CCR2B-MAPK pathway. CONCLUSIONS: BEV/CCR2i showed a sustained anticancer immunity-independent effect in human ovarian cancer that was more significant in serous carcinoma than in clear cell carcinoma.

    英語, 研究論文(学術雑誌), Cancer stem cells (CSCs) has been a key target to cure cancer patients completely. Although many CSC markers have been identified, they are frequently cancer type-specific and those expressions are occasionally variable, which becomes an obstacle to elucidate the characteristics of the CSCs. Here we scrutinized the relationship between stemness elevation and geometrical features of single cells. The PAMPS hydrogel was utilized to create the CSCs from mouse myoblast C2C12 and its synovial sarcoma model cells. qRT-PCR analysis confirmed the significant increase in expression levels of Sox2, Nanog, and Oct3/4 on the PAMPS gel, which was higher in the synovial sarcoma model cells. Of note, the morphological heterogeneity was appeared on the PAMPS gel, mainly including flat spreading, elongated spindle, and small round cells, and the Sox2 expression was highest in the small round cells. To examine the role of morphological differences in the elevation of stemness, over 6,400 cells were segmented along with the Sox2 intensity, and 12 geometrical features were extracted at single cell level. A nonlinear mapping of the geometrical features by using uniform manifold approximation and projection (UMAP) clearly revealed the existence of relationship between morphological differences and the stemness elevation, especially for C2C12 and its synovial sarcoma model on the PAMPS gel in which the small round cells possess relatively high Sox2 expression on the PAMPS gel, which supports the strong relationship between morphological changes and the stemness elevation. Taken together, these geometrical features can be useful for morphological profiling of CSCs to classify and distinguish them for understanding of their role in disease progression and drug discovery.

    英語, 研究論文(学術雑誌), Retinoic acid (RA) and its synthetic derivatives, retinoids, have been established as promising anticancer agents based on their ability to regulate cell proliferation and survival. Clinical trials, however, have revealed that cancer cells often acquire resistance to retinoid therapy. Therefore, elucidation of underlying mechanisms of retinoid resistance has been considered key to developing more effective use of retinoids in cancer treatment. In this study, we show that constitutive activation of ERK MAP kinase signaling, which is often caused by oncogenic mutations in RAS or RAF genes, suppresses RA receptor (RAR) signaling in breast cancer cells. We show that activation of the ERK pathway suppresses, whereas its inhibition promotes, RA-induced transcriptional activation of RAR and the resultant upregulation of RAR-target genes in breast cancer cells. Importantly, ERK inhibition potentiates the tumor-suppressive activity of RA in breast cancer cells. Moreover, we also reveal that suppression of RAR signaling and activation of ERK signaling are associated with poor prognoses in breast cancer patients and represent hallmarks of specific subtypes of breast cancers, such as basal-like, HER2-enriched and luminal B. These results indicate that ERK-dependent suppression of RAR activity underlies retinoid resistance and is associated with cancer subtypes and patient prognosis in breast cancers.

    英語, 研究論文(学術雑誌), The SARS-CoV-2 Omicron BA.2.75 variant emerged in May 2022. BA.2.75 is a BA.2 descendant but is phylogenetically distinct from BA.5, the currently predominant BA.2 descendant. Here, we show that BA.2.75 has a greater effective reproduction number and different immunogenicity profile than BA.5. We determined the sensitivity of BA.2.75 to vaccinee and convalescent sera as well as a panel of clinically available antiviral drugs and antibodies. Antiviral drugs largely retained potency, but antibody sensitivity varied depending on several key BA.2.75-specific substitutions. The BA.2.75 spike exhibited a profoundly higher affinity for its human receptor, ACE2. Additionally, the fusogenicity, growth efficiency in human alveolar epithelial cells, and intrinsic pathogenicity in hamsters of BA.2.75 were greater than those of BA.2. Our multilevel investigations suggest that BA.2.75 acquired virological properties independent of BA.5, and the potential risk of BA.2.75 to global health is greater than that of BA.5.

    英語, 研究論文(学術雑誌), Knowledge of the histologic type and primary origin of pulmonary tumors is essential when preparing a surgical strategy. Intraoperative diagnosis of hematoxylin and eosin (H&E)-stained frozen sections is the gold standard, but reliable pathology requires time-consuming immunohistochemistry (IHC) to distinguish among histological types/organ origins and to analyze molecular status. The aim of this study was to evaluate the clinical reliability of a new rapid-IHC technique for intraoperative diagnosis of pulmonary tumors. In total, 169 patients with undiagnosed pulmonary tumors were enrolled in a multicenter prospective observational study. At three institutes, pulmonary tumor samples were collected through core needle biopsy and/or surgery to determine surgical strategies. Using a new device for rapid IHC, we applied a high-voltage, low-frequency alternating current (AC) field, which mixes the available antibody as the voltage is switched on/off. Rapid IHC can provide tumor histologic type/origin diagnoses within 20 min, as opposed to the 3-6 h required for conventional IHC. No false diagnoses of malignancy were rendered in any of the cases when using simple H&E staining. With H&E staining alone, the overall definitive diagnosis rate, the rate of defined tumor origin, and the rate of determined histological type were 76.92%, 85.80%, and 90.53%, respectively. When rapid IHC was added, those rates were significantly improved to 88.76%, 94.67%, and 91.72%, respectively. By providing prompt and accurate intraoperative histological/molecular analysis, rapid IHC driven by AC mixing could serve as an effective clinical tool guiding the surgical strategy for undiagnosed pulmonary tumors.

    研究論文(学術雑誌), Abstract

    Living organisms share the ability to grow various microstructures on their surface to achieve functions. Here we present a force stamp method to grow microstructures on the surface of hydrogels based on a force-triggered polymerisation mechanism of double-network hydrogels. This method allows fast spatial modulation of the morphology and chemistry of the hydrogel surface within seconds for on-demand functions. We demonstrate the oriented growth of cells and directional transportation of water droplets on the engineered hydrogel surfaces. This force-triggered method to chemically engineer the hydrogel surfaces provides a new tool in addition to the conventional methods using light or heat, and will promote the wide application of hydrogels in various fields.

    英語, Krabbe disease is a lysosomal storage disease caused by a deficiency of the galactocerebrosidase (GALC) enzyme, which leads to demyelination of the central and peripheral nervous systems. Almost all patients with Krabbe disease are infants, and this is the first report of adult-onset cases that describe pathological findings. Here, we present two autopsy cases: a 73-year-old female and a 2-year-old male. The adult-onset case developed symptoms in her late thirties and was diagnosed by the identification of GALC D528N and L634S mutations and by T2-weighted magnetic resonance imaging; she had increased signal in the white matter along the pyramidal tract to the bilateral precentral gyrus, as well as from the triangular part to the posterior horn of the lateral ventricle. Microscopically, Klüver-Barrera staining was pale in the white matter of the precentral gyrus and occipito-thalamic radiation, and a few globoid cells were observed. The GALC mutations that were identified in the present adult-onset case do not completely inactivate GALC enzyme activity, resulting in focal demyelination of the brain.

    英語, 研究論文(学術雑誌), Solitary fibrous tumors (SFTs) are rare mesenchymal tumors that can occur at any location. Since the identification of specific NAB2-STAT6 fusion in SFTs, the fusion gene variants, NAB2 exon 4-STAT6 exon 2/3 and NAB2 exon 5/6/7-STAT6 exon 16/17/18, have been reported to be associated with clinicopathological features, and the latter variant is predominant in meningeal SFTs. SFTs developing in the salivary glands are rare, and more rarely, those involving ectopic salivary glands (ESGs) have been reported in the cerebellopontine angle (CPA); however, their characteristics remain not well understood. In this study, we performed a clinicopathological and molecular analysis of 3 cases of meningeal SFT with ESGs. All cases presented with an extra-axial mass in the CPA, which is a rarer location for intracranial ESGs compared to the sellar region. Histologically, except for the presence of ESGs, there was no significant difference between current cases and ordinary SFTs. The ESGs demonstrated no cellular atypia, and although the spindle tumor cells were immunopositive for STAT6, the ESGs were negative in all cases, supporting that the ESGs are non-neoplastic components. In 1 case, ESGs were found only in the primary tumor and disappeared in recurrence/dissemination. Of note, molecular analysis identified NAB2 exon 4-STAT6 exon 2 in all cases. In conclusion, our results suggest that ESGs particularly in the CPA may be associated with SFTs and that meningeal SFTs with ESGs may be associated with the minor fusion variant of NAB2-STAT6 in the intracranial lesions.

    英語, 研究論文(学術雑誌), Soon after the emergence and global spread of the SARS-CoV-2 Omicron lineage BA.1, another Omicron lineage, BA.2, began outcompeting BA.1. The results of statistical analysis showed that the effective reproduction number of BA.2 is 1.4-fold higher than that of BA.1. Neutralization experiments revealed that immunity induced by COVID vaccines widely administered to human populations is not effective against BA.2, similar to BA.1, and that the antigenicity of BA.2 is notably different from that of BA.1. Cell culture experiments showed that the BA.2 spike confers higher replication efficacy in human nasal epithelial cells and is more efficient in mediating syncytia formation than the BA.1 spike. Furthermore, infection experiments using hamsters indicated that the BA.2 spike-bearing virus is more pathogenic than the BA.1 spike-bearing virus. Altogether, the results of our multiscale investigations suggest that the risk of BA.2 to global health is potentially higher than that of BA.1.

    英語, 研究論文(学術雑誌), The aim of this study was to analyze the clinical and radiological characteristics of glioblastomas (GBMs) harboring a BRAF mutation. Sequencing analysis of BRAF, IDH1/2, and TERT promoters was performed on GBM samples of patients older than 15 years. The clinical, pathological, and radiological data of patients were retrospectively reviewed. Patients were classified into three groups according to their BRAF and IDH1/2 status: BRAF group, IDH group, and BRAF/IDH-wild-type (WT) group. Among 179 GBM cases, we identified nine cases with a BRAF mutation and nine with IDH mutation. The WT group had 161 cases. Age at onset in the BRAF group was significantly lower compared to the WT group and was similar to the IDH group. In cases with negative IDH1-R132H staining and age < 55 years, 15.2% were BRAF-mutant cases. Similar to the IDH group, overall survival of the BRAF group was significantly longer compared with the WT group. Among nine cases in the BRAF group, three cases had hemorrhagic onset and prior lesions were observed in two cases. In conclusion, age < 55 years, being IDH1-R132H negative, with hemorrhagic onset or the presence of prior lesions are factors that signal recommendation of BRAF analysis for adult GBM patients.

    英語, 研究論文(学術雑誌), Recently, we have developed a hydroxyapatite (HAp)-hybridized double-network (DN) hydrogel (HAp/DN gel), which can robustly bond to the bone tissue in the living body. The purpose of this study is to clarify whether the HAp/DN gel surface can differentiate the bone marrow-derived mesenchymal stem cells (MSCs) to osteogenic cells. We used the MSCs which were harvested from the rabbit bone marrow and cultured on the polystyrene (PS) dish using the autogenous serum-supplemented medium. First, we confirmed the properties of MSCs by evaluating colony forming unit capacity, expression of MSC markers using flow cytometry, and multidifferential capacity. Secondly, polymerase chain reaction analysis demonstrated that the HAp/DN gel surface significantly enhanced mRNA expression of the eight osteogenic markers (TGF-β1, BMP-2, Runx2, Col-1, ALP, OPN, BSP, and OCN) in the cultured MSCs at 7 days than the PS surfaces (p < 0.0001), while the DN gel and HAp surfaces provided no or only a slight effect on the expression of these markers except for Runx2. Additionally, the alkaline phosphatase activity was significantly higher in the cells cultured on the HAp/DN gel surface than in the other three material surfaces (p < 0.0001). Thirdly, when the HAp/DN gel plug was implanted into the rabbit bone marrow, MSC marker-positive cells were recruited in the tissue generated around the plug at 3 days, and Runx2 and OCN were highly expressed in these cells. In conclusion, this study demonstrated that the HAp/DN gel surface can differentiate the MSCs into osteogenic cells.

    英語, 研究論文(学術雑誌), The emergence of the Omicron variant of SARS-CoV-2 is an urgent global health concern1. In this study, our statistical modelling suggests that Omicron has spread more rapidly than the Delta variant in several countries including South Africa. Cell culture experiments showed Omicron to be less fusogenic than Delta and than an ancestral strain of SARS-CoV-2. Although the spike (S) protein of Delta is efficiently cleaved into two subunits, which facilitates cell-cell fusion2,3, the Omicron S protein was less efficiently cleaved compared to the S proteins of Delta and ancestral SARS-CoV-2. Furthermore, in a hamster model, Omicron showed decreased lung infectivity and was less pathogenic compared to Delta and ancestral SARS-CoV-2. Our multiscale investigations reveal the virological characteristics of Omicron, including rapid growth in the human population, lower fusogenicity and attenuated pathogenicity.

    Abstract

    Neural regeneration is extremely difficult to achieve. In traumatic brain injuries, the loss of brain parenchyma volume hinders neural regeneration. In this study, neuronal tissue engineering was performed by using electrically charged hydrogels composed of cationic and anionic monomers in a 1:1 ratio (C1A1 hydrogel), which served as an effective scaffold for the attachment of neural stem cells (NSCs). In the 3D environment of porous C1A1 hydrogels engineered by the cryogelation technique, NSCs differentiated into neuroglial cells. The C1A1 porous hydrogel was implanted into brain defects in a mouse traumatic damage model. The VEGF-immersed C1A1 porous hydrogel promoted host-derived vascular network formation together with the infiltration of macrophages/microglia and astrocytes into the gel. Furthermore, the stepwise transplantation of GFP-labeled NSCs supported differentiation to glial and neuronal cells. Therefore, this two-step method for neural regeneration may become a new approach for therapeutic brain tissue reconstruction after brain damage in the future.

    英語, 研究論文(学術雑誌), It is important to determine the activation status of Rac and Cdc42 in cancer tissues for the prediction of metastasis and patient prognosis. However, it has been impossible to detect their spatial activation on formalin-fixed paraffin embedded (FFPE) surgical specimens thus far. Here, we established a novel detection technique for activated Rac/Cdc42 in human colon cancer FFPE tissues by using a p21-activated kinase (PAK)-Rac binding domain (RBD) detection probe fused with glutathione S-transferase (GST), designated GST-PAK-RBD, and novel rapid-immunohistochemistry (R-IHC) systems using noncontact alterating-current electric field mixing, although there is a technical limitation in that it may not distinguish between Rac members and Cdc42. In 50 cases of colon cancer, various activation patterns of Rac/Cdc42 were observed, which were designated plasma membrane, cytoplasm, mixed pattern, and polarized distribution. The activity was striking in the invasive fronts of tumors and significantly correlated with tumor invasion properties evaluated by TNM classification. Of note, in tissue microarray (TMA) samples, 29 of 33 cases demonstrated higher Rac1/Cdc42 activity in the tumor area than the corresponding normal mucosa. In addition, positive correlations were detected between Rac/Cdc42 activity and clinicopathological factors such as venous and lymphatic vessel invasion. These results suggest that understanding Rac and Cdc42 activations in cancer tissues would be valuable as an option for molecular therapy as personalized medicine.

    英語, 研究論文(学術雑誌), During the current coronavirus disease 2019 (COVID-19) pandemic, a variety of mutations have accumulated in the viral genome of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and, at the time of writing, four variants of concern are considered to be potentially hazardous to human society1. The recently emerged B.1.617.2/Delta variant of concern is closely associated with the COVID-19 surge that occurred in India in the spring of 2021 (ref. 2). However, the virological properties of B.1.617.2/Delta remain unclear. Here we show that the B.1.617.2/Delta variant is highly fusogenic and notably more pathogenic than prototypic SARS-CoV-2 in infected hamsters. The P681R mutation in the spike protein, which is highly conserved in this lineage, facilitates cleavage of the spike protein and enhances viral fusogenicity. Moreover, we demonstrate that the P681R-bearing virus exhibits higher pathogenicity compared with its parental virus. Our data suggest that the P681R mutation is a hallmark of the virological phenotype of the B.1.617.2/Delta variant and is associated with enhanced pathogenicity.

    英語, 研究論文(学術雑誌), PURPOSE: To identify the germline genetic characteristics of long-term recurrence-free survivors that can be applied to establishing a new strategy for curing advanced cancer, we investigated the whole-genome single nucleotide variants of ovarian cancer patients. PATIENTS AND METHODS: DNA specimens were obtained from rare long-term recurrence-free survivors with FIGO stage III-IV ovarian cancer with no recurrence for 8-23 years after primary treatments for a whole-genome analysis of approximately 660,000 single nucleotide variants. We then established a mouse model with a notable gene alteration by CRISPR/Cas9 to confirm the biological role. RESULTS: The long-term recurrence-free survivors more frequently had germline heterozygous variant rs2185379 of the PRDM1 gene exon than patients with early recurrence (6.8-fold, P=0.013) and the general population. In the mouse model, primary intraperitoneal disseminated tumors of allograft ID8 were significantly smaller in the germline heterozygous rs2185379 group than in the wild-type group (57.4% decrease, P=0.008). Immunohistochemistry showed that the area of distribution of infiltrating T lymphocytes with positive CD8 staining was significantly increased in the germline heterozygous rs2185379 group in comparison to the wild-type group. CONCLUSION: Germline heterozygous rs2185379 in PRDM1 is correlated with an excellent prognosis and can be used to establish a new strategy for treating advanced ovarian cancer.

    英語, 研究論文(学術雑誌), In 2020, the worldwide incidence and mortality of colorectal cancer (CRC) were third and second, respectively. As the 5-y survival rate is low when CRC is diagnosed at an advanced stage, a reliable method to predict CRC susceptibility is important for preventing the onset and development and improving the prognosis of CRC. Therefore, we focused on the normal colonic mucosa to investigate changes in gene expression that may induce subsequent genetic alterations that induce malignant transformation. Comprehensive gene expression profiling in the normal mucosa adjacent to colon cancer (CC) compared with tissue from non-colon cancer patients was performed. PCR arrays and qRT-PCR revealed that the expression of 5 genes involved in the immune response, including MYD88, was increased in the normal mucosa of CC patients. The expression levels of MYD88 were strikingly increased in precancerous normal mucosa specimens, which harbored no somatic mutations, as shown by immunohistochemistry. Microarray analysis identified 2 novel RNA-controlling molecules, EXOSC3 and CNOT4, that were significantly upregulated in the normal mucosa of CC patients and were clearly visualized in the nuclei. Forced expression of EXOSC3 and CNOT4 in human colonic epithelial cells increased the expression of IFNGR1, MYD88, NFκBIA, and STAT3 and activated ERK1/2 and JNK in 293T cells. Taken together, these results suggested that, in the inflamed mucosa, EXOSC3- and CNOT4-mediated RNA stabilization, including that of MYD88, may trigger the development of cancer and can serve as a potential predictive marker and innovative treatment to control cancer development.

    英語, 研究論文(学術雑誌), Adult T-cell leukemia/lymphoma (ATLL) is an aggressive T-cell malignancy with a poor prognosis with current therapy. Here we report genome-wide CRISPR-Cas9 screening of ATLL models, which identified CDK6, CCND2, BATF3, JUNB, STAT3, and IL10RB as genes that are essential for the proliferation and/or survival of ATLL cells. As a single agent, the CDK6 inhibitor palbociclib induced cell cycle arrest and apoptosis in ATLL models with wild type TP53. ATLL models that had inactivated TP53 genetically were relatively resistant to palbociclib owing to compensatory CDK2 activity, and this resistance could be reversed by APR-246, a small molecule activator of mutant TP53. The CRISPR-Cas9 screen further highlighted the dependence of ATLL cells on mTORC1 signaling. Treatment of ATLL cells with palbociclib in combination with mTORC1 inhibitors was synergistically toxic irrespective of the TP53 status. This work defines CDK6 as a novel therapeutic target for ATLL and supports the clinical evaluation of palbociclib in combination with mTORC1 inhibitors in this recalcitrant malignancy.

    英語, 研究論文(学術雑誌), BACKGROUNDS: FAM83H is essential for amelogenesis, but recent reports implicate that FAM83H is involved in the tumorigenesis. We previously clarified that TRIM29 binds to FAM83H to regulate keratin distribution and squamous cell migration. However, little is known about FAM83H in normal/malignant skin keratinocytes. OBJECTIVE: To investigate the expression of FAM83H in cutaneous squamous cell carcinoma (SCC) and its physiological function. METHODS: Immunohistochemical analysis and RT-PCR of human SCC tissues were performed. Next, we examined the effect of FAM83H knockdown/overexpression in SCC cell lines using cell proliferation, migration, and invasion assay. To investigate the molecular mechanism, immunoprecipitation of FAM83H was examined. Further, Immunofluorescence staining was performed. Finally, we examined the correlation between the expressions of FAM83H and the keratin distribution. RESULTS: FAM83H expression was lower in SCC lesions than in normal epidermis and correlated with differentiation grade. The mRNA expression levels of FAM83H in SCC tumors were also lower than in normal epidermis. The knockdown of FAM83H enhanced SCC cell migration and invasion, whereas the overexpression of FAM83H led to decreases in both. Furthermore, the knockdown of FAM83H enhanced the cancer cell metastasis in vivo. FAM83H formed a complex with TRIM29 and keratins. The knockdown of FAM83H altered keratin distribution and solubility. Clinically, the loss of FAM83H correlates with an altered keratin distribution. CONCLUSION: Our findings reveal a critical function for FAM83H in regulating keratin distribution, as well as in the migration/invasion of cutaneous SCC, suggesting that FAM83H could be a crucial molecule in the tumorigenesis of cutaneous SCC.

    英語, 研究論文(学術雑誌), The acquisition of mesenchymal traits leads to immune evasion in various cancers, but the underlying molecular mechanisms remain unclear. In this study, we found that the expression levels of AT-rich interaction domain-containing protein 5a (Arid5a), an RNA-binding protein, were substantially increased in mesenchymal tumor subtypes. The deletion of Arid5a in tumor cell lines enhanced antitumor immunity in immunocompetent mice, but not in immunodeficient mice, suggesting a role for Arid5a in immune evasion. Furthermore, an Arid5a-deficient tumor microenvironment was shown to have robust antitumor immunity, as manifested by suppressed infiltration of granulocytic myeloid-derived suppressor cells and regulatory T cells. In addition, infiltrated T cells were more cytotoxic and less exhausted. Mechanistically, Arid5a stabilized Ido1 and Ccl2 mRNAs and augmented their expression, resulting in enhanced tryptophan catabolism and an immunosuppressive tumor microenvironment. Thus, our findings demonstrate the role of Arid5a beyond inflammatory diseases and suggest Arid5a as a promising target for the treatment of immunotolerant malignant tumors.See related Spotlight by Van den Eynde, p. 854.

    英語, 研究論文(学術雑誌), At the early stage of cancer development, oncogenic mutations often cause multilayered epithelial structures. However, the underlying molecular mechanism still remains enigmatic. By performing a series of screenings targeting plasma membrane proteins, we have found that collagen XVII (COL17A1) and CD44 accumulate in RasV12-, Src-, or ErbB2-transformed epithelial cells. In addition, the expression of COL17A1 and CD44 is also regulated by cell density and upon apical cell extrusion. We further demonstrate that the expression of COL17A1 and CD44 is profoundly upregulated at the upper layers of multilayered, transformed epithelia in vitro and in vivo. The accumulated COL17A1 and CD44 suppress mitochondrial membrane potential and reactive oxygen species (ROS) production. The diminished intracellular ROS level then promotes resistance against ferroptosis-mediated cell death upon cell extrusion, thereby positively regulating the formation of multilayered structures. To further understand the functional role of COL17A1, we performed comprehensive metabolome analysis and compared intracellular metabolites between RasV12 and COL17A1-knockout RasV12 cells. The data imply that COL17A1 regulates the metabolic pathway from the GABA shunt to mitochondrial complex I through succinate, thereby suppressing the ROS production. Moreover, we demonstrate that CD44 regulates membrane accumulation of COL17A1 in multilayered structures. These results suggest that CD44 and COL17A1 are crucial regulators for the clonal expansion of transformed cells within multilayered epithelia, thus being potential targets for early diagnosis and preventive treatment for precancerous lesions.

    英語, 研究論文(学術雑誌), Information regarding the molecular features of pulmonary pleomorphic carcinoma (PPC) is insufficient. Here, we performed next-generation sequencing to determine the genomic and transcriptomic profiles of PPC. We sequenced the DNAs and RNAs of 78 specimens from 52 patients with PPC. We analyzed 15 PPC cases to identify intratumoral differences in gene alterations, tumor mutation burden (TMB), RNA expression, and PD-L1 expression between epithelial and sarcomatoid components. The genomic alterations of six cases of primary tumors and corresponding metastatic tumors were analyzed. KRAS mutations (27%) were the most common driver mutations, followed by EGFR (8%), and MET (8%) mutations. Epithelial and sarcomatoid components shared activating driver mutations, and there were no significant differences in CD274 expression or TMB between the two components. However, PD-L1 was highly expressed in the sarcomatoid component of several cases compared with the epithelial component. Primary and metastatic tumors shared oncogenic mutations among genes such as KRAS and TP53, and additional alterations including NOTCH4 mutations were specifically identified in the metastatic regions. Our data suggest that therapies targeting activating driver mutations may be effective for patients with PPC and that immune checkpoint inhibitors of PPC may be recommended after careful assessment of PD-L1 expression in each epithelial and sarcomatoid component.

    英語, 研究論文(学術雑誌), Oligodendrogliomas are defined by mutation in isocitrate dehydrogenase (NADP(+)) (IDH)1/2 genes and chromosome 1p/19q codeletion. World Health Organisation diagnosis endorses testing for 1p/19q codeletion to distinguish IDH mutant (Mut) oligodendrogliomas from astrocytomas because these gliomas require different treatments and they have different outcomes. Several methods have been used to identify 1p/19q status; however, these techniques are not routinely available and require substantial infrastructure investment. Two recent studies reported reduced immunostaining for trimethylation at lysine 27 on histone H3 (H3K27me3) in IDH Mut 1p/19q codeleted oligodendroglioma. However, the specificity of H3K27me3 immunostaining in this setting is controversial. Therefore, we developed an easy-to-implement immunohistochemical surrogate for IDH Mut glioma subclassification and evaluated a validated adult glioma cohort. We screened 145 adult glioma cases, consisting of 45 IDH Mut and 1p/19q codeleted oligodendrogliomas, 30 IDH Mut astrocytomas, 16 IDH wild-type (Wt) astrocytomas, and 54 IDH Wt glioblastomas (GBMs). We compared immunostaining with DNA sequencing and fluorescent in situ hybridization analysis and assessed differences in H3K27me3 staining between oligodendroglial and astrocytic lineages and between IDH1-R132H and non-canonical (non-R132H) IDH1/2 Mut oligodendroglioma. A loss of H3K27me3 was observed in 36/40 (90%) of IDH1-R132H Mut oligodendroglioma. In contrast, loss of H3K27me3 was never seen in IDH1-R132L or IDH2-mutated 1p/19q codeleted oligodendrogliomas. IDH Mut astrocytoma, IDH Wt astrocytoma and GBM showed preserved nuclear staining in 87%, 94%, and 91% of cases, respectively. A high recursive partitioning model predicted probability score (0.9835) indicated that the loss of H3K27me3 is frequent to IDH1-R132H Mut oligodendroglioma. Our results demonstrate H3K27me3 immunohistochemical evaluation to be a cost-effective and reliable method for defining 1p/19q codeletion along with IDH1-R132H and ATRX immunostaining, even in the absence of 1p/19q testing.
  • Difference in the malignancy between RAS and GLI1-transformed astrocytes is associated with frequency of p27KIP1-positive cells in xenograft tissues.

    英語, 研究論文(学術雑誌), We demonstrate that the introduction of GLI1 is sufficient for immortalized human astrocytes to be transformed whereas FOXM1 fails to induce malignant transformation, suggesting differences between GLI1 and FOXM1 in terms of transforming ability despite both transcription factors being overexpressed in malignant gliomas. Moreover, in investigations of mechanisms underlying relatively less-malignant features of GLI1-transformed astrocytes, we found that p27KIP1-positive cells were frequently observed in xenografts derived from GLI1-transformed astrocytes compared to those from RAS-transformed cells. As shRNA-mediated knockdown of p27KIP1 accelerates tumor progression of GLI1-transformed astrocytes, downregulation of p27KIP1 contributes to malignant features of transformed astrocytes. We propose that the models using immortalized/transformed astrocytes are useful to identify the minimal and most crucial set of changes required for glioma formation.

    英語, 研究論文(学術雑誌), BACKGROUND: Subclinical Cushing's disease (SCD) is defined by corticotroph adenoma-induced mild hypercortisolism without typical physical features of Cushing's disease. Infection is an important complication associated with mortality in Cushing's disease, while no reports on infection in SCD are available. To make clinicians aware of the risk of infection in SCD, we report a case of SCD with disseminated herpes zoster (DHZ) with the mortal outcome. CASE PRESENTATION: An 83-year-old Japanese woman was diagnosed with SCD, treated with cabergoline in the outpatient. She was hospitalized for acute pyelonephritis, and her fever gradually resolved with antibiotics. However, herpes zoster appeared on her chest, and the eruptions rapidly spread over the body. She suddenly went into cardiopulmonary arrest and died. Autopsy demonstrated adrenocorticotropic hormone-positive pituitary adenoma, renal abscess, and DHZ. CONCLUSIONS: As immunosuppression caused by SCD may be one of the triggers of severe infection, the patients with SCD should be assessed not only for the metabolic but also for the immunodeficient status.
  • Distinct TERT promoter C228T and C250T mutations in a patient with an oligodendroglioma: A case report.

    英語, The majority of oligodendroglial tumors harbor mutations in the telomerase reverse transcriptase (TERT) gene (TERT) promoter and the isocitrate dehydrogenase 1/2 (IDH1/2) gene (IDH1/2), as well as 1p/19q codeletion. Generally, TERT promoter mutations, C250T and C228T, are mutually exclusive. We present a case of oligodendroglioma harboring both C250T and C228T mutations in TERT promoter. A 38-year-old man presented with grand mal seizures and underwent a resection surgery for a left frontal lobe tumor. He was pathologically diagnosed as having oligodendroglioma and was carefully observed. At 48 years of age, he underwent another resection surgery due to tumor regrowth, with the pathological diagnosis of anaplastic oligodendroglioma. Genetic analysis of the initial tumor specimen revealed IDH1 R132H mutation and both C250T and C228T mutations in TERT promoter. Using mutation-specific primers, two mutations were considered to be distributed in different alleles. In the tumor specimen obtained during the second surgery, IDH1 R132H mutation was detected to be similar to that of the initial specimen; however, only C228T mutation was detected in TERT promoter. The 1p/19q codeletion was detected in both the initial and recurrent tumor specimens. According to the sequencing data from the two tumor specimens, although TERT promoter mutation has been considered to be an early genetic event in the tumorigenesis of oligodendroglial tumors, it is likely that the C250T and C228T mutations in TERT promoter are subclonally distributed in the same tumor specimen of the present case.

    英語, 研究論文(学術雑誌), Oral squamous cell carcinoma (OSCC) impairs functionality and sensuousness resulting in poor quality of life. Biomarkers can predict disease trajectory and lead to effective treatments. Transcriptomics have identified genes that are upregulated in tumor endothelial cells (TECs) compared with normal endothelial cells (NECs). Among them, chemokine receptor 7 (CXCR7) is highly expressed in TECs of several cancers and involved in angiogenesis of TECs. However, levels of CXCR7 in OSCC blood vessels have not been fully investigated. In this study, we analyzed the correlation between CXCR7 expression in TECs and clinicopathological factors in OSCC. Immunohistochemistry for CXCR7 and CD34 was performed on 59 OSCC tissue specimens resected between 1996 and 2008 at Hokkaido University Hospital. CXCR7 expression in blood vessels was evaluated by the ratio of CXCR7+/CD34+ blood vessels. CXCR7 expression was 42% and 19% in tumor and non-tumor parts, respectively, suggesting that CXCR7 expression is higher in TECs than in NECs. CXCR7 expression in TECs correlated with advanced T-stage and cancer stage. Overall survival and disease-free survival rates were higher in low-expressing CXCR7 patients than in high-expressing. These results suggest that CXCR7 expression in blood vessels may be a useful diagnostic and prognostic marker for OSCC patients.

    英語, 研究論文(学術雑誌), Cancer recurrence can arise owing to rare circulating cancer stem cells (CSCs) that are resistant to chemotherapies and radiotherapies. Here, we show that a double-network hydrogel can rapidly reprogramme differentiated cancer cells into CSCs. Spheroids expressing elevated levels of the stemness genes Sox2, Oct3/4 and Nanog formed within 24 h of seeding the gel with cells from any of six human cancer cell lines or with brain cancer cells resected from patients with glioblastoma. Human brain cancer cells cultured on the double-network hydrogel and intracranially injected in immunodeficient mice led to higher tumorigenicity than brain cancer cells cultured on single-network gels. We also show that the double-network gel induced the phosphorylation of tyrosine kinases, that gel-induced CSCs from primary brain cancer cells were eradicated by an inhibitor of the platelet-derived growth factor receptor, and that calcium channel receptors and the protein osteopontin were essential for the regulation of gel-mediated induction of stemness in brain cancer cells.

    英語, A 5-year-old girl presented with headache and vomiting. Head computed tomography and magnetic resonance imaging showed a right frontal lobe tumor with marked calcification. The patient underwent resection surgery with suspicion of anaplastic ependymoma, and the tumor was gross totally removed. Pathological examination revealed areas of dense tumor cells with a high nucleocytoplasmic ratio and myxoid areas consisting of tumor cells with a round-shaped nucleus and eosinophilic cytoplasm. Perivascular pseudorosette, necrosis, circumscribed growth, and microcalcification were also observed. Immunohistochemistry demonstrated negative staining for glial fibrillary protein and epithelial membrane antigen. Diagnosis of a high-grade neuroepithelial tumor (HGNET) with BCL6 corepressor (BCOR) alteration was made based on pathological findings and internal tandem duplication in the exon 15 of BCOR. Although calcification on radiological and pathological examination is not typical, it would be essential to recognize that calcification could appear in HGNET-BCOR.

    英語, 研究論文(学術雑誌), Here we present the case of a 73-year-old male with rectal adenocarcinoma with heterotopic ossification (HO). Cancer-associated HO in the digestive system is rare. Thus, the precise mechanism and clinicopathological significance of HO have not yet been defined. To clarify the molecular mechanisms of HO, we analyzed the expression levels of signaling molecules related to epithelial-mesenchymal transition (EMT) that lead to ossification in the tumor cells discriminating the ossified area (HO-area) and non-ossified area (non-HO area). Expression levels of BMP4 were elevated in both areas, whereas BMP2 was specifically increased in the HO-area by qPCR. EMT-related molecules such as Snail and Slug were especially higher in the HO-area. By immunohistochemistry, the expression of Smad4, nuclear staining of β-catenin, and the phosphorylated form of GSK-3β were detectable in both areas, and GSK-3β was highly phosphorylated in the HO-area. The tumor growth rate was extremely high, with the Ki-67 labeling index at 90%. In the HO-area, osteoblasts with alkaline phosphatase expression were distributed surrounding the tumor cells. This is the first demonstration of the involvement of EMT in HO of colon cancer through BMP/SMAD and WNT/β-catenin signaling pathways, which are especially prominent in the HO-area leading to the osteogenic property.

    英語, 研究論文(学術雑誌), We previously demonstrated that a synthetic negatively charged poly(2-acrylamido-2-methylpropanesulfonic acid) (PAMPS) gel induced chondrogenic differentiation of ATDC5 cells. In this study, we clarified the underlying molecular mechanism, in particular, focusing on the events that occurred at the interface between the gel and the cells. Gene expression profiling revealed that the expression of extracellular components was enhanced in the ATDC5 cells that were cultured on the PAMPS gel, suggesting that extracellular proteins secreted from the ATDC5 cells might be adsorbed in the PAMPS gel, thereby contributing to the induction of chondrogenic differentiation. Therefore, we created "Treated-PAMPS gel," which adsorbed various proteins secreted from the cultured ATDC5 cells during 7 days. Proteomic analysis identified 27 proteins, including extracellular matrix proteins such as Types I, III, and V collagens and thrombospondin (THBS) in the Treated-PAMPS gel. The Treated-PAMPS gel preferentially induced expression of chondrogenic markers, namely, aggrecan and Type II collagen, in the ATDC5 cells compared with the untreated PAMPS gel. Addition of recombinant THBS1 to the ATDC5 cells significantly enhanced the PAMPS-induced chondrogenic differentiation, whereas knockdown of THBS1 completely abolished this response. In conclusion, we demonstrated that the PAMPS gel has the potential to induce chondrogenic differentiation through novel reservoir functions, and the adsorbed THBS plays a significant role in the induction.

    英語, 研究論文(学術雑誌), Recurrent fusion genes involving C11orf95, C11orf95-RELA, have been identified only in supratentorial ependymomas among primary CNS tumors. Here, we report hitherto histopathologically unclassifiable high-grade tumors, under the tentative label of "ependymoma-like tumors with mesenchymal differentiation (ELTMDs)," harboring C11orf95-NCOA1/2 or -RELA fusion. We examined the clinicopathological and molecular features in five cases of ELTMDs. Except for one adult case (50 years old), all cases were in children ranging from 1 to 2.5 years old. All patients presented with a mass lesion in the cerebral hemisphere. Histologically, all cases demonstrated a similar histology with a mixture of components. The major components were embryonal-appearing components forming well-delineated tumor cell nests composed of small uniform cells with high proliferative activity, and spindle-cell mesenchymal components with a low- to high-grade sarcoma-like appearance. The embryonal-appearing components exhibited minimal ependymal differentiation including a characteristic EMA positivity and tubular structures, but histologically did not fit with ependymoma because they lacked perivascular pseudorosettes, a histological hallmark of ependymoma, formed well-delineated nests, and had diffuse and strong staining for CAM5.2. Molecular analysis identified C11orf95-NCOA1, -NCOA2, and -RELA in two, one, and two cases, respectively. t-distributed stochastic neighbor embedding analysis of DNA methylation data from two cases with C11orf95-NCOA1 or -NCOA2 and a reference set of 380 CNS tumors revealed that these two cases were clustered together and were distinct from all subgroups of ependymomas. In conclusion, although ELTMDs exhibited morphological and genetic associations with supratentorial ependymoma with C11orf95-RELA, they cannot be regarded as ependymoma. Further analyses of more cases are needed to clarify their differences and similarities.

    英語, 研究論文(学術雑誌), OBJECTIVES: Although electrolyte abnormalities are related to worse clinical outcomes in patients with acute myocardial infarction (AMI), little is known about the association between admission serum magnesium level and adverse events in AMI patients complicated by out-of-hospital cardiac arrest presenting with malignant ventricular arrhythmias (OHCA-MVA). We investigated the prognostic value of serum magnesium level on admission in these patients. METHODS: We retrospectively analyzed the data of 165 consecutive reperfused AMI patients complicated with OHCA-MVA between April 2007 and February 2020 in our university hospital. Serum magnesium concentration was measured on admission. The primary outcome was in-hospital death. RESULTS: Fifty-four patients (33%) died during hospitalization. Higher serum magnesium level was significantly related to in-hospital death (Fine & Gray's test; p < 0.001). In multivariable logistic regression analyses, serum magnesium level on admission was independently associated with in-hospital death (hazard ratio 2.68, 95% confidence interval 1.24-5.80) even after adjustment for covariates. Furthermore, the incidences of cardiogenic shock necessitating an intra-aortic balloon pump (p = 0.005) or extracorporeal membrane oxygenation (p < 0.001), tracheal intubation (p < 0.001) and persistent vegetative state (p = 0.002) were significantly higher in patients with higher serum magnesium level than in those with lower serum magnesium level. CONCLUSIONS: In reperfused AMI patients complicated by OHCA-MVA, admission serum magnesium level might be a potential surrogate marker for predicting in-hospital death.

    英語, 研究論文(学術雑誌), Tough double network (DN) hydrogels are promising substitutes of soft supporting tissues such as cartilage and ligaments. For such applications, it is indispensable to robustly fix the hydrogels to bones with medically feasible methods. Recently, robustly bonding the DN hydrogels to defected bones of rabbits in vivo has been proved successful. The low crystalline hydroxyapatite (HAp) of calcium-phosphate-hydroxide salt coated on the surface layer of the DN hydrogels induced spontaneous osteogenesis penetrating into the semi-permeable hydrogels to form a gel/bone composite layer. In this work, the 44 Ca isotope-doped HAp/DN hydrogel is implanted in a defect of rabbit femoral bone and the dynamic osteogenesis process at the gel/bone interface is analyzed by tracing the calcium isotope ratio using isotope microscopy. The synthetic HAp hybridized on the surface layer of DN gel dissolves rapidly in the first two weeks by inflammation, and then the immature bone with a gradient structure starts to form in the gel region, reutilizing the dissolved Ca ions. These results reveal, for the first time, that synthetic HAp is reutilized for osteogenesis. These facts help to understand the lifetime of bone absorbable materials and to elucidate the mechanism of spontaneous, non-toxic, but strong fixation of hydrogels to bones.

    英語, 研究論文(学術雑誌), Heart failure (HF) occurs frequently among older individuals, and dysfunction of cardiac mitochondria is often observed. We here show the cardiac-specific downregulation of a certain mitochondrial component during the chronological aging of mice, which is detrimental to the heart. MitoNEET is a mitochondrial outer membrane protein, encoded by CDGSH iron sulfur domain 1 (CISD1). Expression of mitoNEET was specifically downregulated in the heart and kidney of chronologically aged mice. Mice with a constitutive cardiac-specific deletion of CISD1 on the C57BL/6J background showed cardiac dysfunction only after 12 months of age and developed HF after 16 months; whereas irregular morphology and higher levels of reactive oxygen species in their cardiac mitochondria were observed at earlier time points. Our results suggest a possible mechanism by which cardiac mitochondria may gradually lose their integrity during natural aging, and shed light on an uncharted molecular basis closely related to age-associated HF.

    英語, 研究論文(学術雑誌), Lewy body disease (LBD) is a spectrum of progressive neurodegenerative disorders characterized by the wide distribution of Lewy bodies and neurites in the central and peripheral nervous system (CNS, PNS). Clinical diagnoses include Parkinson's disease (PD), dementia with Lewy bodies, or pure autonomic failure. All types of LBD are accompanied by non-motor symptoms (NMSs) including gastrointestinal dysfunctions such as constipation. Its relationship to Lewy body-related α-synucleinopathy (Lewy pathology) of the enteric nervous system (ENS) is attracting attention because it can precede the motor symptoms. To clarify the role of ENS Lewy pathology in disease progression, we performed a clinicopathological study using the Brain Bank for Aging Research in Japan. Five-hundred and eighteen cases were enrolled in the study. Lewy pathology of the CNS and PNS, including the lower esophagus as a representative of the ENS, was examined via autopsy findings. Results showed that one-third of older people (178 cases, 34%) exhibited Lewy pathology, of which 78 cases (43.8%) exhibited the pathology in the esophagus. In the esophageal wall, Auerbach's plexus (41.6%) was most susceptible to the pathology, followed by the adventitia (33.1%) and Meissner's plexus (14.6%). Lewy pathology of the esophagus was significantly associated with autonomic failures such as constipation (p < 0.0001) and among PNS regions, correlated the most with LBD progression (r = 0.95, p < 0.05). These findings suggest that the propagation of esophageal Lewy pathology is a predictive factor of LBD.
  • Brain-Derived Neurotrophic Factor Improves Impaired Fatty Acid Oxidation Via the Activation of Adenosine Monophosphate-Activated Protein Kinase-ɑ - Proliferator-Activated Receptor-r Coactivator-1ɑ Signaling in Skeletal Muscle of Mice With Heart Failure.

    Circulation. Heart failure, 14, 1, e005890, 2021年01月, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: We recently reported that treatment with rhBDNF (recombinant human brain-derived neurotrophic factor) improved the reduced exercise capacity of mice with heart failure (HF) after myocardial infarction (MI). Since BDNF is reported to enhance fatty acid oxidation, we herein conducted an in vivo investigation to determine whether the improvement in exercise capacity is due to the enhancement of the fatty acid oxidation of skeletal muscle via the AMPKα-PGC1α (adenosine monophosphate-activated protein kinase-ɑ-proliferator-activated receptor-r coactivator-1ɑ) axis. METHODS: MI and sham operations were conducted in C57BL/6J mice. Two weeks postsurgery, we randomly divided the MI mice into groups treated with rhBDNF or vehicle for 2 weeks. AMPKα-PGC1α signaling and mitochondrial content in the skeletal muscle of the mice were evaluated by Western blotting and transmission electron microscopy. Fatty acid β-oxidation was examined by high-resolution respirometry using permeabilized muscle fiber. BDNF-knockout mice were treated with 5-aminoimidazole-4-carboxamide-1-beta-d-riboruranoside, an activator of AMPK. RESULTS: The rhBDNF treatment significantly increased the expressions of phosphorylated AMPKα and PGC1α protein and the intermyofibrillar mitochondrial density in the MI mice. The lowered skeletal muscle mitochondrial fatty acid oxidation was significantly improved in the rhBDNF-treated MI mice. The reduced exercise capacity and mitochondrial dysfunction of the BDNF-knockout mice were improved by 5-aminoimidazole-4-carboxamide-1-beta-d-riboruranoside. CONCLUSIONS: Beneficial effects of BDNF on the exercise capacity of mice with HF are mediated through an enhancement of fatty acid oxidation via the activation of AMPKα-PGC1α in skeletal muscle. BDNF may become a therapeutic option to improve exercise capacity as an alternative or adjunct to exercise training.

  • Loss of dynamin-related protein 1 (Drp1) does not affect epidermal development or UVB-induced apoptosis but does accelerate UVB-induced carcinogenesis.

    英語, 研究論文(学術雑誌), BACKGROUND: Mitochondrial morphology is controlled by fission and fusion. Dynamin-related protein 1 (Drp1, dynamin-1-like protein (Dnml1)) regulates mitochondrial fission, which is associated with cell division and apoptosis. We previously reported that DRP1 is indispensable for cell growth in cutaneous squamous cell carcinoma. However, little is known about Drp1 in normal epidermis/keratinocytes. OBJECTIVES: We investigated the function of Drp1 in normal epidermis/keratinocytes. METHODS: Epidermis-specific Drp1 knockout (EKO) mice were analyzed. RESULTS: Epidermal development in the EKO mice were indistinguishable from those in the wild-type (WT) mice. Ultrastructural analysis and immunohistochemistry revealed that the mitochondria of keratinocytes in the EKO mice were neither elongated nor constricted. Drp1 knockdown did not diminish the cell growth of normal human keratinocytes. Both in vivo and in vitro, UVB-induced apoptosis in the EKO epidermis and keratinocytes did not differ from that in the WT mice. In chronic UVB-irradiation, the loss of Drp1 sensitized the epidermis to the development of skin tumors. Clinically, DRP1 is expressed more highly in sun-exposed skin than in non-exposed skin in individuals under age 40, but not in those over age 60. CONCLUSION: EKO mice demonstrate that Drp1 is dispensable for the development and apoptosis of the epidermis. Drp1 plays critical roles in malignant tumors; thus, the molecular machinery of mitochondrial dynamics involving Drp1 could be a novel therapeutic target for malignant keratinocytic lesions. On the other hand, the anti-tumorigenic role of Drp1 in chronic UVB-induced carcinogenesis need to be further investigated.

Patients with spinal cord diffuse glioma regardless of World Health Organization (WHO) grade underwent genetic analysis for H3F3A, HIST1H3B, TERT promoter, IDH1/2, and BRAF. H3K27me3 status and EZH2 expression were analyzed through immunohistochemistry. Thereafter, the association between H3K27M, H3K27me3 status, and EZH2 expression and prognosis was retrospectively analyzed using the log-rank test. A total of 26 cases, 5 with WHO grade 4, 9 with grade 3, and 12 with grade 2 glioma, were analyzed. Although WHO grade 2 cases tended to present favorable overall survival, the difference was not statistically significant. H3K27M, which was detected in four grade 4 cases (80%) and three grade 3 cases (33%), was not associated with prognosis among grade 3 and 4 cases. Among WHO grade 2-4 cases, the combination of retained H3K27me3 and negative EZH2 expression was correlated with favorable overall survival (p = 0.03). The combination of H3K27me3 status and EZH2 expression was considered as a potential prognostic marker in WHO grade 2-4 diffuse spinal cord gliomas.

    英語, 研究論文(学術雑誌), Negatively charged synthetic hydrogels have been known to facilitate various cellular responses including cell adhesion, proliferation, and differentiation; however, the molecular mechanism of hydrogel-dependent control of cell behavior remains unclear. Recently, we reported that negatively charged poly(2-acrylamido-2-methylpropanesulfonic acid) (PAMPS) gel induces chondrogenic differentiation of ATDC5 cells via novel protein reservoir function. In this study, we identified the cell adhesion molecules binding to PAMPS gels that act as mechanoreceptors. First, we performed a pull-down assay by particle gels using cell membrane proteins of ATDC5, and found that multiple membrane proteins bound to the PAMPS gel, whereas the uncharged poly(N,N'-dimethylacrylamide) gel as control did not bind to any membrane proteins. Western blot analysis indicated differential binding of integrin (ITG) isoforms to the PAMPS gel, in which the α4 isoform, but not α5 and αv, efficiently bound to the PAMPS gel. ITG α4 knockdown decreased cell spreading of ATDC5 on PAMPS gels, whereas the enhanced expression increased the behavior. Furthermore, ITG α4 depletion suppressed PAMPS gel-induced expression of bone morphogenic protein (BMP) 4 contributing to chondrogenic differentiation, in concordance with the reduction of ERK activation. These results demonstrated that membrane protein binding to PAMPS gels occurred in a charge-dependent manner, and that ITG α4 plays a crucial role in cell spreading on PAMPS gels and acts as a mechanoreceptor triggering cellular signaling leads to chondrogenic differentiation.

    英語, 研究論文(学術雑誌), Signaling adaptor protein Crk has been shown to play an important role in various human cancers. Crk links tyrosine kinases and guanine nucleotide exchange factors (GEFs) such as C3G and Dock180 to activate small G-proteins Rap and Rac, respectively. In pancreatic cancer, various molecular targeted therapies have provided no significant therapeutic benefit for the patients so far due to constitutive activation of KRAS by frequent KRAS mutation. Therefore, the establishment of novel molecular targeted therapy in KRAS-independent manner is required. Here, we investigated a potential of Crk as a therapeutic target in pancreatic cancer. Immunohistochemistry on human pancreatic cancer specimens revealed that the patients with high expression of Crk had a worse prognosis than those with low expression. We established Crk-knockdown pancreatic cancer cells by siRNA using PANC-1, AsPC-1, and MIA PaCa-2 cells, which showed decreased cell proliferation, invasion, and adhesion. In Crk-knockdown pancreatic cancer cells, the decrease of c-Met phosphorylation was observed. In the orthotopic xenograft model, Crk depletion prolonged survival of mice significantly. Thus, signaling adaptor protein Crk is involved in malignant potential of pancreatic cancer associated with decrease of c-Met phosphorylation, and Crk can be considered to be a potential therapeutic molecular target.

    英語, 研究論文(学術雑誌), Pineoblastomas (PBs) are rare, aggressive pediatric brain tumors of the pineal gland with modest overall survival despite intensive therapy. We sought to define the clinical and molecular spectra of PB to inform new treatment approaches for this orphan cancer. Tumor, blood, and clinical data from 91 patients with PB or supratentorial primitive neuroectodermal tumor (sPNETs/CNS-PNETs), and 2 pineal parenchymal tumors of intermediate differentiation (PPTIDs) were collected from 29 centres in the Rare Brain Tumor Consortium. We used global DNA methylation profiling to define a core group of PB from 72/93 cases, which were delineated into five molecular sub-groups. Copy number, whole exome and targeted sequencing, and miRNA expression analyses were used to evaluate the clinico-pathologic significance of each sub-group. Tumors designated as group 1 and 2 almost exclusively exhibited deleterious homozygous loss-of-function alterations in miRNA biogenesis genes (DICER1, DROSHA, and DGCR8) in 62 and 100% of group 1 and 2 tumors, respectively. Recurrent alterations of the oncogenic MYC-miR-17/92-RB1 pathway were observed in the RB and MYC sub-group, respectively, characterized by RB1 loss with gain of miR-17/92, and recurrent gain or amplification of MYC. PB sub-groups exhibited distinct clinical features: group 1-3 arose in older children (median ages 5.2-14.0 years) and had intermediate to excellent survival (5-year OS of 68.0-100%), while Group RB and MYC PB patients were much younger (median age 1.3-1.4 years) with dismal survival (5-year OS 37.5% and 28.6%, respectively). We identified age < 3 years at diagnosis, metastatic disease, omission of upfront radiation, and chr 16q loss as significant negative prognostic factors across all PBs. Our findings demonstrate that PB exhibits substantial molecular heterogeneity with sub-group-associated clinical phenotypes and survival. In addition to revealing novel biology and therapeutics, molecular sub-grouping of PB can be exploited to reduce treatment intensity for patients with favorable biology tumors.

    英語, 研究論文(学術雑誌), Over the past 30 years, the therapeutic outcome for pancreatic ductal adenocarcinoma (PDAC) has remained stagnant due to the lack of effective treatments. We performed a genome-wide analysis to identify novel therapeutic targets for PDAC. Our analysis showed that Homo sapiens chromosome 16 open reading frame 74 (C16orf74) was upregulated in most patients with PDAC and associated with poor prognosis. Previously, we demonstrated that C16orf74 interacts with the catalytic subunit alpha of protein phosphatase 3 and plays an important role in PDAC invasion. However, the pathophysiologic function of C16orf74 is still unclear. In this study, through the analysis of C16orf74 interaction, we demonstrate a new strategy to inhibit the growth and invasion of PDAC. C16orf74 exists in the homodimer form under the cell membrane and binds integrin αVβ3 and is also involved in invasion by activating Rho family (Rac1) and MMP2. Considering that this dimeric form was found to be involved in the function of C16orf74, we designed an 11R-DB (dimer block) cell-permeable dominant-negative peptide that inhibits the dimer form of C16orf74. 11R-DB suppressed invasion and proliferation of PDAC cell lines by inhibiting phosphorylation of Akt and mTOR and also by inactivation of MMP2. 11R-DB also showed antitumor effects in an orthotopic xenograft model and peritoneal metastasis model. Thus, this study demonstrates that dimerized C16orf74, present in the cell membrane, is involved in pancreatic cancer invasion and proliferation. In addition, the C16orf74 dimer block cell-permeable peptide (11R-DB) has a potent therapeutic effect on PDAC in vitro and in vivo.

    英語, 研究論文(学術雑誌), RATIONALE: Rosette-forming glioneuronal tumor (RGNT) is a rare tumor which has been first reported as the fourth ventricle tumor by Komori et al and is classified as a distinct clinicopathological entity by the WHO Classification of Tumors of the Central Nervous System as in 2007. Although RGNTs were reported to occur in both supratentorial and inflatentorial sites, only 4 case reports of spinal RGNT have been demonstrated. PATIENT CONCERNS: A 37-year-old female presenting with slowly progressing right-sided clumsiness. Cervical magnetic resonance imaging revealed a spinal intramedullary tumor between the C2 and C5 levels. DIAGNOSES: Pathological analysis showed unique biphasic cellular architecture consisting of perivascular pseudorosettes dominantly with few neurocytic rosettes and diffuse astrocytoma component. The tumor cells composed of perivascular pseudorosettes showed positivity for both synaptophysin and glial markers such as GFAP and Olig2. Therefore, the diagnosis of RGNT was made. INTERVENTIONS: Gross total resection of the tumor was achieved. No adjuvant chemotherapy nor radiotherapy was conducted after operation. OUTCOMES: At 2 years after the operation, no recurrence was observed. LESSONS: Although RGNT arising from the spinal cord is extremely rare, we need to consider the tumor as a differential diagnosis for intramedullary spinal cord tumors.

    英語, 研究論文(学術雑誌), Diffuse type gastric cancer (DGC), a pathological subtype, is one of the most common malignant solid tumors, and mortality of this tumor is not negligible, especially in early-onset cancer patients. In fact, affirmative personalized treatments based on gene profile have not been established yet. The aim of this study was to provide the possible genotype-matched treatment for DGC through comprehensive examination of genomic variants and analysis of clinicopathological characteristics. We retrospectively studied 23 formalin-fixed, paraffin-embedded samples of patients diagnosed as DGC between January 2003 and December 2015 at the Department of Cancer Pathology, Hokkaido University Graduate School of Medicine. The cases were divided into two groups: early-onset (< 50 years old) and elderly-onset (≥ 50 years old) DGC groups. We performed targeted genomic sequencing using a 163 cancer-related gene panel. The sequencing data were analyzed using an original bioinformatics pipeline called GenomeJack and were clinicopathologically evaluated. Intestinal metaplasia and atrophy were highly observed in the adjacent non-cancerous mucosa in the elderly-onset DGC group compared with those in the early-onset DGC group. The number of somatic variants was significantly higher in the elderly-onset DGC group than in the early-onset DGC group. Fifteen patients (65.2%) harbored at least one genomic alteration of the potential target for genotype-matched treatment. In addition, one patient with hypermutation phenotype was diagnosed as Lynch syndrome due to MLH1 mutation, suggesting the sensitivity for the treatment with immune checkpoint inhibitors. Not only does our study demonstrated the potential utility of the targeted genomic sequencing approach for making informed therapeutic decisions, but it also sheds light on DGC pathogenesis and progression.

    英語, Dropped head syndrome (DHS) has been rarely observed in amyotrophic lateral sclerosis (ALS), and the neuropathological findings of this condition have almost never been described. The identification of transactivation response DNA-binding protein 43 kDa (TDP-43), which binds to RNA/DNA has provided a new method for studying ALS and frontotemporal lobar degeneration (FTLD). Post-mortem examination of an adult sudden death case of a 71-year-old patient who complained of DHS exhibited severe loss of anterior motor neurons in the cervical cord (C4-6). Loss of nerve fibers of the anterior roots was striking compared with posterior roots, together with marked neurogenic atrophy of posterior muscles semispinalis cervicis. Bunina bodies were found in large neurons of Betz giant cells, but not in the motor neurons of spinal cords, or neurons of bulbar regions. Phosphorylated TDP-43 (p-TDP-43)-positive structures were detected in the residual neurons of the cervical, thoracic and lumber cords, hypoglossal nucleus, cerebellar dentate nucleus and parahippocampal cortex, together with ubiquitin-positive inclusions. Phosphorylated Tau positive structures in neuronal cytoplasm were found in the amygdala, entorhinal cortex and parahippocampal cortex, some of which co-expressed p-TDP-43. The medial zone of cervical cords may be the first onset site, and that is the cause of head drop in the early stage of ALS. In spite of detailed examination, the direct cause of sudden death was not verified. This autopsy report revealed the relation of DHS which is a rare clinical manifestation of ALS, and neuropathological findings.

    英語, 研究論文(学術雑誌), Gastric hyperplastic polyps are common and generally regarded as benign lesions, whereas gastric adenocarcinomas infrequently occur from gastric hyperplastic polyps. Although gastric hyperplastic polyps have received a lot of attention because of their association with malignant transformation, it remains unclear whether gastric hyperplastic polyps are neoplastic lesions that have sporadic genetic changes similar to colorectal hyperplastic polyps. We performed genome-wide analyses of two gastric adenocarcinomas with hyperplastic polyp components. The interface between "adenocarcinoma" and "hyperplastic polyp" components was fairly sharp, and the adenocarcinoma components had copy number alterations and TP53 mutations, whereas the hyperplastic polyp components had only single nucleotide polymorphisms, which were also found in adenocarcinoma components. We did not detect any somatic changes in the hyperplastic polyp components, even in genome-wide analyses, which was in contrast to the adenocarcinoma components. However, due to the small number of cases examined herein, further genetic analyses of more cases are needed.

    英語, 研究論文(学術雑誌), Obstructive sleep apnea (OSA) is associated with coronary artery disease (CAD) and with an increased risk for myocardial infarction, stroke or death due to cardiovascular disease. Optical frequency-domain imaging (OFDI) is a useful modality for evaluating the characteristics of atherosclerotic plaque. The purpose of the study was to use OFDI to investigate the association of OSA with coronary plaque characteristics in patients undergoing percutaneous coronary intervention (PCI). We retrospectively analyzed OFDI data for coronary artery plaques from 15 patients with OSA and 35 non-OSA patients treated between October 2015 and October 2018. Plaque morphology was evaluated for 70 lesions, including 21 from patients with OSA and 49 from non-OSA patients. Compared with the non-OSA group, patients with OSA had significantly higher prevalences of thinned cap fibroatheroma (TCFA) (67% vs. 35%, P = 0.014) and microchannels (86% vs. 55%, P = 0.014); a significantly higher mean lipid index (1392 ± 982 vs. 817 ± 699, P = 0.021), macrophage grade (8.4 ± 6.4 vs. 4.8 ± 4.5, P = 0.030), and maximum number of microchannels (1.5 ± 1.0 vs. 0.7 ± 0.7, P = 0.001); and a significantly lower mean minimum fibrous cap thickness (69.4 ± 28.7 vs. 96.1 ± 51.8 μm, P = 0.008). This OFDI analysis suggests that OSA is associated with unstable plaque characteristics in patients with CAD. More intensive medical management for stabilization of coronary atherosclerotic plaque is required in patients with OSA.
  • Exosomes containing ErbB2/CRK induce vascular growth in premetastatic niches and promote metastasis of bladder cancer.

    英語, 研究論文(学術雑誌), Locally advanced and metastatic invasive bladder cancer (BC) has a poor prognosis, and no advanced therapies beyond cisplatin-based combination chemotherapy have been developed. Therefore, it is an urgent issue to elucidate the underlying mechanisms of tumor progression and metastasis of invasive BC for the development of new therapeutic strategies. Here, we clarified a novel role of exosomes containing ErbB2 and CRK in a formation of premetastatic niches and subsequent metastases. CRK adaptors were overexpressed in invasive UM-UC-3 BC cells. In an orthotopic xenograft model, metastases to lung, liver, and bone of UM-UC-3 cells were completely abolished by CRK elimination. Mass spectrometry analysis identified that ErbB2 was contained in UM-UC-3-derived exosomes in a CRK-dependent manner; the exosomes significantly increased proliferation and invasion properties of low-grade 5637 BC cells and HUVECs through FAK and PI3K/AKT signaling pathways. In athymic mice educated with UM-UC-3-derived exosomes, i.v. implanted UM-UC-3 cells were trapped with surrounding PKH67-labeled exosomes in lung and led to development of lung metastasis with disordered vascular proliferation. In contrast, exosomes derived from CRK-depleted BC cells failed to induce these malignant features. Taken together, we showed that CRK adaptors elevated the expression of ErbB2/3 in BC cells, and these tyrosine kinase/adaptor units were transferred from host BC cells to metastatic recipient cells by exosomes, leading to vascular leakiness and proliferation and contributing to the formation of distant metastasis. Thus, CRK intervention with ErbB2/3 blockade might be a potent therapeutic strategy for patients with ErbB2 overexpressing advanced and metastatic BC.

    英語, 研究論文(学術雑誌), BACKGROUND: The relationship between eicosapentaenoic acid (EPA) therapy and coronary plaque stability assessed by optical frequency domain imaging (OFDI) has not been thoroughly described. HYPOTHESIS: EPA therapy is associated with decreased plaque instability in patients undergoing percutaneous coronary intervention (PCI) using OFDI. METHODS: Data on coronary artery plaques from 121 patients who consecutively underwent PCI between October 2015 and July 2018 were retrospectively analyzed. Of these patients, 109 were untreated (no-EPA group), whereas 12 were treated with EPA (EPA group). Each plaque's morphological characteristics were analyzed using OFDI. RESULTS: We used 1:4 propensity score matching for patients who received or did not receive EPA therapy before PCI. Baseline characteristics were balanced between both groups (age, sex, body mass index, diabetes mellitus, hypertension, dyslipidemia, chronic kidney disease, smoking, previous PCI or coronary artery bypass grafting, previous myocardial infarction, prior statin use, acute coronary syndrome, hemoglobin A1c level, low-density lipoprotein cholesterol concentration, triglyceride concentration, and high-density lipoprotein cholesterol concentration). OFDI data from 60 patients were analyzed in this study. The EPA group had significantly lower mean lipid index (818 ± 806 vs 1574 ± 891) and macrophage grade (13.5 ± 5.9 vs 19.3 ± 7.4) but higher mean minimum fibrous cap thickness (109.2 ± 55.7 vs 81.6 ± 36.4 μm) than the no-EPA group (P = 0.010, 0.019, and 0.040, respectively). Multiple logistic regression analyses showed that prior EPA use was independently associated with lower lipid index and macrophage grade (P = 0.043 and 0.024, respectively). CONCLUSION: This OFDI analysis suggests that EPA therapy is associated with decreased plaque instability in patients undergoing PCI.

    英語, 研究論文(学術雑誌), Tumor molecular profiling is becoming a standard of care for patients with cancer, but the optimal platform for cancer sequencing remains undetermined. We established a comprehensive assay, the Todai OncoPanel (TOP), which consists of DNA and RNA hybridization capture-based next-generation sequencing panels. A novel method for target enrichment, named the junction capture method, was developed for the RNA panel to accurately and cost-effectively detect 365 fusion genes as well as aberrantly spliced transcripts. The TOP RNA panel can also measure the expression profiles of an additional 109 genes. The TOP DNA panel was developed to detect single nucleotide variants and insertions/deletions for 464 genes, to calculate tumor mutation burden and microsatellite instability status, and to infer chromosomal copy number. Clinically relevant somatic mutations were identified in 32.2% (59/183) of patients by prospective TOP testing, signifying the clinical utility of TOP for providing personalized medicine to cancer patients.

    英語, 研究論文(学術雑誌), Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is characterized by the production of ANCAs and systemic necrotizing vasculitis in small vessels. Disordered regulation of neutrophil extracellular traps (NETs) is critically involved in the pathogenesis of AAV. NETs are web-like DNA decorated with antimicrobial proteins; they are extruded from activated neutrophils. The principal degradation factor of NETs in vivo is DNase I; however, NETs resistant to DNase I can persist in tissues and can lead to the production of ANCAs. Deposition of NETs has been demonstrated in glomerular crescents and necrotizing vasculitis in AAV. Here, the amount of NETs in formalin-fixed, paraffin-embedded tissue sections was examined, and the results for AAV were compared with the results for diseases that should be distinguished from AAV. NETs were more abundant in necrotizing vasculitis of AAV than in non-ANCA-associated vasculitis, or in granulomatous angiitis. Pulmonary granulomas in AAV and non-ANCA-associated diseases were further studied. The amount of NETs was significantly greater in necrotizing granulomas of AAV than in granulomas of sarcoidosis without necrosis. Although NETs were formed in necrotizing granulomas of tuberculosis equivalently to those formed in AAV, they were more susceptible to degradation by DNase I than were NETs in AAV. The formation and disordered degradation of NETs in necrotizing lesions are characteristics of AAV and are possibly related to its pathogenesis.

    英語, The publication of the 2016 World Health Organization Classification of Tumors of the Central Nervous System (2016 WHO CNS) represented a major change in the classification of brain tumors. However, many pathologists in Japan cannot diagnose astrocytic or oligodendroglial tumors according to the 2016 WHO CNS due to financial or technical problems. Therefore, the Japan Society of Brain Tumor Pathology established a committee for molecular diagnosis to facilitate the integrated diagnosis of astrocytic and oligodendroglial tumors in Japan. We created three levels of diagnoses: Level 1 was defined as simple histopathological diagnosis using hematoxylin and eosin staining and routine cell lineage-based immunostaining. Level 2 was defined as immunohistochemical diagnosis using immunohistochemical examinations using R132H mutation-specific IDH1, ATRX, and/or p53 antibodies. Level 3 was defined as molecular diagnosis, such as diagnosis based on 1p/19q status or the mutation status of the IDH1 and IDH2 genes. In principle, astrocytic and oligodendroglial tumors should be diagnosed based on the 2016 WHO CNS and/or cIMPACT-NOW criteria; however, the findings obtained through our diagnostic flowchart can be added to the histological diagnosis in parentheses. This classification system would be helpful for pathologists with limited resources.
  • Autopsy report of a late delayed radiation injury after a period of 45 years.

    Neuropathology : official journal of the Japanese Society of Neuropathology, 39, 2, 106, 110, 2019年04月, [査読有り], [国際誌]
    英語, For delayed radiation injury, image analysis has considerably advanced, but neuropathological findings are still required to establish diagnosis. A patient who had received radiation therapy for pineal germinoma at age 14 developed neurological and psychiatric abnormalities after 15 years as a late delayed radiation injury. Autopsy at age 59 revealed diffuse changes in the white matter consisting in order of severity of myelin pallor, demyelination, and necrosis which were characterized by a lack of glial reaction. The cerebral cortex was relatively well preserved. As delayed radiation injuries, hyalinous changes in the vascular wall, angiomatous lesions and, fresh and old petechial hemorrhages were found. Moreover, vascular changes associated with arteriosclerosis were also present. Furthermore, a focal glial nodule was detected which was considered to be a new radiation-induced neoplasia. These findings suggest that late delayed radiation injury may slowly develop over 30 years and may involve damage to neuroglial stem cell compensation. It is also evident that arteriosclerotic changes and newly induced neoplasia may develop in delayed radiation injury cases.

    英語, BACKGROUND & AIMS: Intraductal papillary mucinous neoplasms (IPMNs) are regarded as precursors of pancreatic ductal adenocarcinomas (PDAs), but little is known about the mechanism of progression. This makes it challenging to assess cancer risk in patients with IPMNs. We investigated associations of IPMNs with concurrent PDAs by genetic and histologic analyses. METHODS: We obtained 30 pancreatic tissues with concurrent PDAs and IPMNs, and 168 lesions, including incipient foci, were mapped, microdissected, and analyzed for mutations in 18 pancreatic cancer-associated genes and expression of tumor suppressors. RESULTS: We determined the clonal relatedness of lesions, based on driver mutations shared by PDAs and concurrent IPMNs, and classified the lesions into 3 subtypes. Twelve PDAs contained driver mutations shared by all concurrent IPMNs, which we called the sequential subtype. This subset was characterized by less diversity in incipient foci with frequent GNAS mutations. Eleven PDAs contained some driver mutations that were shared with concurrent IPMNs, which we called the branch-off subtype. In this subtype, PDAs and IPMNs had identical KRAS mutations but different GNAS mutations, although the lesions were adjacent. Whole-exome sequencing and methylation analysis of these lesions indicated clonal origin with later divergence. Ten PDAs had driver mutations not found in concurrent IPMNs, called the de novo subtype. Expression profiles of TP53 and SMAD4 increased our ability to differentiate these subtypes compared with sequencing data alone. The branch-off and de novo subtypes had substantial heterogeneity among early clones, such as differences in KRAS mutations. Patients with PDAs of the branch-off subtype had a longer times of disease-free survival than patients with PDAs of the de novo or the sequential subtypes. CONCLUSIONS: Detailed histologic and genetic analysis of PDAs and concurrent IPMNs identified 3 different pathways by which IPMNs progress to PDAs-we call these the sequential, branch-off, and de novo subtypes. Subtypes might be associated with clinical and pathologic features and be used to select surveillance programs for patients with IPMNs.

    英語, BACKGROUND:  It is very rare for a choroid plexus tumor to occur intraparenchymally in the absence of a relation to the choroid plexus. CLINICAL PRESENTATION:  A case of cerebral intraparenchymal choroid plexus tumor in a 30-year-old woman presenting with left hemiparesis is described. Brain magnetic resonance imaging depicted a large cystic mass in the right frontal lobe. Tumor resection was performed by right frontal craniotomy. No connection with the choroid plexus was observed during the operation. Histologically, the tumor exhibited a glandular structure with a papillary pattern suggesting a neoplasm of epithelial origin. Immunohistochemical analyses revealed the tumor as an atypical choroid plexus papilloma. CONCLUSION:  Immunohistochemical findings, especially regarding Kir7.1, are very important for the differential diagnosis of cerebral intraparenchymal choroid plexus tumors from metastatic tumors. The present case reveals that an atypical choroid plexus papilloma can occur intraparenchymally without an association with the choroid plexus. Intraparenchymal atypical choroid plexus papillomas may have previously been diagnosed incorrectly as metastatic adenocarcinomas of unknown origin.

    英語, 研究論文(学術雑誌), A 24 year-old female presented with a mass lesion in the right temporal lobe. This case was difficult to diagnose using histological and immunological methods and therefore molecular analyses were applied to provide a definitive diagnosis. The tumor was well-demarcated, partially cystic, and irregularly-enhanced on gadolinium-enhanced T1-weighted magnetic resonance images. Pathologically, a large part of the tumor consisted of cells with fine cytoplasmic processes on a myxoid and mucinous background. Cells formed a microcystic structure around the mucinous tissue. Numerous eosinophilic granular bodies, but not Rosenthal fibers, were present. The solid and compact regions of the tumor were composed of fasciculation of dense fibrous glial tissues and occasional multinucleated giant cells. Tumor cells and their fragmented cytoplasmic processes were positively stained with GFAP, while eosinophilic granular bodies were both positive and negative. Xanthomatous changes were not detected and the reticulin fibers were restricted to vascular tissues. The MIB1 index was scored as approximately 10%. In molecular analyses of BRAF, the KIAA1549-BRAF (K16-B9) fusion gene was detected in all tumor regions, whereas BRAF V600E mutation was not detected by either conventional Sanger sequencing or the Eprobe-PCR method. Based on the results of the molecular analyses, this case was diagnosed as pilocytic astrocytoma.

    英語, 研究論文(学術雑誌), Mechanically robust hydrogels are promising biomaterials as artificial supportive tissue. These applications require selective and robust bonding of the hydrogels to living tissue. Recently, we achieved strong in vivo bone bonding of a tough double network (DN) hydrogel, a potential material for use as artificial cartilage and tendon, by hybridizing osteoconductive hydroxyapatite (HAp) in the gel surface layer. In this work, we report micro patterning of HAp at the surface of the DN hydrogel for selective osteoconduction. Utilizing the dissolution of HAp in an acidic environment, the soft lithography technique using an acid gel stamp was adopted to form a high-resolution HAp pattern on the gel. The HAp-patterned gel showed well-regulated migration and adhesion of cells in vitro. Moreover, the HAp-patterned gel showed selective and robust bonding to the rabbit bone tissue in vivo. This HAp soft lithography technique allows for simple and quick preparation of tailor-made osteoconductive hydrogels and can be applied to other hydrogels for selective bone bonding. STATEMENT OF SIGNIFICANCE: Hydrogels, preserving large amount of water, have been studied for next-generation artificial soft tissues. However, fixation of hydrogels to living tissue was unsolved issue for clinical application. Recently, we achieved robust bonding of a tough double network gel to bone in vivo by coating of osteoconductive hydroxyapatite in the gel surface layer. For further progress for practical use, we report the micro patterning of HAp at the surface of the DN hydrogel by using soft lithography technique, to perform selective bonding to only objective area without unnecessary coalescence. The HAp lithography technique is simple, quick and non-toxic method to prepare tailor-made osteoconductive hydrogels and has universality of species of hydrogels.

    英語, 研究論文(学術雑誌), BACKGROUND: Although newly diagnosed high-grade glioma patients in Japan can receive bevacizumab (BEV) as first-line chemotherapy, randomized clinical trials have not shown a survival benefit for BEV for these patients. In this study, we investigated whether selective add-on BEV for patients with newly diagnosed glioblastoma (GBM) and anaplastic astrocytoma (AA) improves prognosis, in cases where tumors were continuously growing during radiotherapy concomitant with temozolomide (TMZ). METHODS: We conducted a retrospective survey of the overall survival (OS) of patients with GBM/AAs who were treated in our institution between 2006 and 2016. Patients whose tumors were continuously growing regardless of radiotherapy were categorized as the "progressive" group; remaining patients were categorized as the "non-progressive" group. Since 2013, patients in the "progressive" group received add-on BEV therapy with the Stupp regimen during or just after radiotherapy. RESULTS: Of 151 GBM/AA patients, 34 (22.5%) were categorized in the "progressive" group. Median OSs of the "progressive" and "non-progressive" groups were 13.2 months and 25.3 months, respectively (P < 0.001). Twelve patients in the "progressive" group received add-on BEV therapy, and their median OS was 20.2 months; whereas for the remaining 22 patients in the "progressive" group who were treated before the BEV era, their median OS was 10.5 months. In the "progressive" group, add-on BEV significantly extended OS (P = 0.018) and was the lone clinical factor of better prognosis. CONCLUSIONS: We found that, for patients with GBM/AAs whose tumors were continuously growing during radiotherapy, add-on BEV treatment resulted in survival benefits.

    英語, 研究論文(学術雑誌), Tumor budding is thought to represent a manifestation of epithelial-to-mesenchymal transition (EMT) and it has been correlated with poor patient outcomes in colorectal cancer (CRC). Our group recently demonstrated that human chorionic gonadotropin-β (hCGβ) modulates EMT in CRC. In the current study, based on the likely relationships between tumor budding and hCGβ expression, we examined their clinicopathologic significance in CRC. Twenty-eight of 80 (35.0%) CRC showed tumor budding. Tumor budding significantly correlated with lymph node metastasis (P < 0.01), pathologic stage (P < 0.01), lymphatic invasion (P = 0.044), and vascular invasion (P = 0.013). Thirteen of 80 (16.3%) CRC were hCGβ positive on immunohistochemistry. More tumor buds were present in the hCGβ-positive cases (P < 0.01), and tumor budding was significantly correlated with hCGβ positivity (P < 0.01). Cases with both tumor budding and hCGβ expression had the poorest prognosis compared with all other groups (P < 0.01). In conclusion, tumor budding and hCGβ expression are closely associated with EMT, and they are independent prognostic factors in CRC. They identify patients with an "EMT phenotype" who may respond to targeted molecular therapies.

    英語, 研究論文(学術雑誌), Clinical diagnosis of progressive supranuclear palsy (PSP) is sometimes difficult because various phenotypes have been identified. Here, we report a mutation in the bassoon (BSN) gene in a family with PSP-like syndrome. Their clinical features resembled not only those of PSP patients but also those of individuals with multiple system atrophy and Alzheimer's disease. The neuropathological findings showed a novel three + four repeat tauopathy with pallido-luysio-nigral degeneration and hippocampal sclerosis. Whole-exome analysis of this family identified a novel missense mutation in BSN. Within the pedigree, the detected BSN mutation was found only in affected individuals. Further genetic analyses were conducted in probands from four other pedigrees with PSP-like syndrome and in 41 sporadic cases. Three missense mutations in BSN that are very rarely listed in databases of healthy subjects were found in four sporadic cases. Western blot analysis of tau following the overexpression of wild-type or mutated BSN revealed the possibility that wild-type BSN reduced tau accumulation, while mutated BSN lost this function. An association between BSN and neurological diseases has not been previously reported. Our results revealed that the neurodegenerative disorder associated with the original proband's pedigree is a novel tauopathy, differing from known dementia and parkinsonism syndromes, including PSP.

    英語, 研究論文(学術雑誌), Ectopic production of free β human chorionic gonadotropin (hCGβ) has been associated with aggressive behavior in non-trophoblastic tumors. hCGβ shares common evolutionary sequences with transforming growth factor-β (TGF-β), which represents a major driving force of epithelial-to-mesenchymal transition (EMT). In this study, we examined the biological roles of hCGβ during EMT and its clinical significance in colorectal cancer (CRC) progression. Eighty CRC specimens and 54 preoperative serum samples were analyzed. hCGβ-overexpressing human CRC cell lines were examined for invasiveness and tumorigenicity, and the expression of EMT-associated genes was investigated. In human CRC, histologic hCGβ positivity [13/80 (16.3%)] was lower than serologic hCGβ positivity [13/54 (24.1%)]. However, it was significantly correlated with several clinicopathological features and unfavorable outcome (P < 0.05). hCGβ-overexpressing cell lines had increased invasiveness, migratory ability, and metastatic potential in mice (P < 0.01). Western blot, PCR, and microarray analyses showed hCGβ altered expression of EMT-related genes, including E-cadherin, phosphorylated SMAD2, SNAIL, and TWIST. hCGβ-induced SNAIL and TWIST overexpression levels were reversible by type I and type II TGF-β receptor inhibitors (P < 0.05). hCGβ thus induces EMT via the TGF-β signaling pathway, and it may represent a molecular target in CRC treatment.

    英語, Glioblastoma is the most aggressive and invasive brain tumor and has a poor prognosis; elucidating the underlying molecular mechanisms is essential to select molecular targeted therapies. Here, we investigated the effect of microRNAs on the marked invasiveness of glioblastoma. U373 glioblastoma cells were infected with 140 different microRNAs from an OncomiR library, and the effects of the invasion-related microRNAs and targeted molecules were investigated after repeated Matrigel invasion assays. Screening of the OncomiR library identified miR-23a as a key regulator of glioblastoma invasion. In six glioblastoma cell lines, a positive correlation was detected between the expression levels of miR-23a and invasiveness. A luciferase reporter assay demonstrated that homeobox D10 (HOXD10) was a miR-23a-target molecule, which was verified by high scores from both the PicTar and miRanda algorithms. Forced expression of miR-23a induced expression of invasion-related molecules, including uPAR, RhoA, and RhoC, and altered expression of glial-mesenchymal transition markers such as Snail, Slug, MMP2, MMP9, MMP14, and E-cadherin; however, these changes in expression levels were reversed by HOXD10 overexpression. Thus, miR-23a significantly promoted invasion of glioblastoma cells with polarized formation of focal adhesions, while exogenous HOXD10 overexpression reversed these phenomena. Here, we identify miR-23a-regulated HOXD10 as a pivotal regulator of invasion in glioblastoma, providing a novel mechanism for the aggressive invasiveness of this tumor and providing insight into potential therapeutic targets.

    英語, BACKGROUND: Unstable atherosclerotic carotid plaques cause cerebral thromboemboli and ischemic events. However, this instability has not been pathologically quantified, so we sought to quantify it in patients undergoing carotid endarterectomy (CEA).Methods and Results:Carotid plaques were collected during CEA from 67 symptomatic and 15 asymptomatic patients between May 2015 and August 2016. The specimens were stained with hematoxylin-eosin and elastica-Masson. Immunohistochemistry was performed using an endothelial-specific antibody to CD31, CD34 and PDGFRβ. The histopathological characteristics of the plaques were studied. By multiple-variable logistic regression analysis, plaque instability correlated with the presence of plaque rupture [odds ratio (OR), 9.75; P=0.013], minimum fibrous cap thickness (OR per 10 μm 0.70; P=0.025), presence of microcalcifications in the fibrous cap (OR 7.82; P=0.022) and intraplaque microvessels (OR 1.91; P=0.043). Receiver-operating characteristics analyses showed that these factors combined into a single score diagnosed symptomatic carotid plaques in patients with carotid artery stenosis with a high level of accuracy (area under the curve 0.92; 95% confidence interval 0.85-0.99 vs. asymptomatic). CONCLUSIONS: This analysis of carotid plaque instability strongly suggested that the diagnostic scoring of carotid plaque instability improves the understanding and treatment of carotid artery disease in patients undergoing CEA.

  • Regulation of endothelial Fas expression as a mechanism of promotion of vascular integrity by mural cells in tumors.

    Cancer science, 108, 5, 1080, 1088, Cancer Science, 2017年05月, [国際誌]
    英語, 研究論文(学術雑誌), Angiogenesis is a multi-step process that culminates in vascular maturation whereby nascent vessels stabilize to become functional, and mural cells play an essential role in this process. Recent studies have shown that mural cells in tumors also promote and maintain vascular integrity, with wide-reaching clinical implications including the regulation of tumor growth, metastases, and drug delivery. Various regulatory signaling pathways have been hitherto implicated, but whether regulation of Fas-dependent apoptotic mechanisms is involved has not yet been fully investigated. We first compared endothelial FAS staining in human pancreatic ductal adenocarcinomas and colon carcinomas and show that the latter, characterized by lower mural cell coverage of tumor vasculature, demonstrated higher expression of FAS than the former. Next, in an in vitro coculture system of MS-1 and 10T1/2 cells as endothelial and mural cells respectively, we show that mural cells decreased endothelial Fas expression. Then, in an in vivo model in which C26 colon carcinoma cells were inoculated together with MS-1 cells alone or with the further addition of 10T1/2 cells, we demonstrate that mural cells prevented hemorrhage. Finally, knockdown of endothelial Fas sufficiently recapitulated the protection against hemorrhage seen with the addition of mural cells. These results together suggest that regulation of endothelial Fas signaling is involved in the promotion of vascular integrity by mural cells in tumors.

    英語, 研究論文(学術雑誌), PURPOSE: Metabolic activity and hypoxia are both important factors characterizing tumor aggressiveness. Here, we used F-18 fluoromisonidazole (FMISO) and F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) to define metabolically active hypoxic volume, and investigate its clinical significance in relation to progression free survival (PFS) and overall survival (OS) in glioblastoma patients. EXPERIMENTAL DESIGN: Glioblastoma patients (n = 32) underwent FMISO PET, FDG PET, and magnetic resonance imaging (MRI) before surgical intervention. FDG and FMISO PET images were coregistered with gadolinium-enhanced T1-weighted MR images. Volume of interest (VOI) of gross tumor volume (GTV) was manually created to enclose the entire gadolinium-positive areas. The FMISO tumor-to-normal region ratio (TNR) and FDG TNR were calculated in a voxel-by-voxel manner. For calculating TNR, standardized uptake value (SUV) was divided by averaged SUV of normal references. Contralateral frontal and parietal cortices were used as the reference region for FDG, whereas the cerebellar cortex was used as the reference region for FMISO. FDG-positive was defined as the FDG TNR ≥1.0, and FMISO-positive was defined as FMISO TNR ≥1.3. Hypoxia volume (HV) was defined as the volume of FMISO-positive and metabolic tumor volume in hypoxia (hMTV) was the volume of FMISO/FDG double-positive. The total lesion glycolysis in hypoxia (hTLG) was hMTV × FDG SUVmean. The extent of resection (EOR) involving cytoreduction surgery was volumetric change based on planimetry methods using MRI. These factors were tested for correlation with patient prognosis. RESULTS: All tumor lesions were FMISO-positive and FDG-positive. Univariate analysis indicated that hMTV, hTLG, and EOR were significantly correlated with PFS (p = 0.007, p = 0.04, and p = 0.01, respectively) and that hMTV, hTLG, and EOR were also significantly correlated with OS (p = 0.0028, p = 0.037, and p = 0.014, respectively). In contrast, none of FDG TNR, FMISO TNR, GTV, HV, patients' age, or Karnofsky performance scale (KPS) was significantly correlated with PSF or OS. The hMTV and hTLG were found to be independent factors affecting PFS and OS on multivariate analysis. CONCLUSIONS: We introduced hMTV and hTLG using FDG and FMISO PET to define metabolically active hypoxic volume. Univariate and multivariate analyses demonstrated that both hMTV and hTLG are significant predictors for PFS and OS in glioblastoma patients.

    英語, 研究論文(学術雑誌), In treating bladder cancer, determining the molecular mechanisms of tumor invasion, metastasis, and drug resistance are urgent to improving long-term patient survival. One of the metabolic enzymes, aldo-keto reductase 1C1 (AKR1C1), plays an essential role in cancer invasion/metastasis and chemoresistance. In orthotopic xenograft models of a human bladder cancer cell line, UM-UC-3, metastatic sublines were established from tumors in the liver, lung, and bone. These cells possessed elevated levels of EMT-associated markers, such as Snail, Slug, or CD44, and exhibited enhanced invasion. By microarray analysis, AKR1C1 was found to be up-regulated in metastatic lesions, which was verified in metastatic human bladder cancer specimens. Decreased invasion caused by AKR1C1 knockdown suggests a novel role of AKR1C1 in cancer invasion, which is probably due to the regulation of Rac1, Src, or Akt. An inflammatory cytokine, interleukin-1β, was found to increase AKR1C1 in bladder cancer cell lines. One particular non-steroidal anti-inflammatory drug, flufenamic acid, antagonized AKR1C1 and decreased the cisplatin-resistance and invasion potential of metastatic sublines. These data uncover the crucial role of AKR1C1 in regulating both metastasis and drug resistance; as a result, AKR1C1 should be a potent molecular target in invasive bladder cancer treatment.

    英語, 研究論文(学術雑誌), PURPOSE: (11)C-methionine (MET) PET is an established diagnostic tool for glioma. Studies have suggested that MET uptake intensity in the tumor is a useful index for predicting patient outcome. Because MET uptake is known to reflect tumor expansion more accurately than MRI, we aimed to elucidate the association between volume-based tumor measurements and patient prognosis. METHODS: The study population comprised 52 patients with newly diagnosed glioma who underwent PET scanning 20 min after injection of 370 MBq MET. The tumor was contoured using a threshold of 1.3 times the activity of the contralateral normal cortex. Metabolic tumor volume (MTV) was defined as the total volume within the boundary. Total lesion methionine uptake (TLMU) was defined as MTV times the mean standardized uptake value (SUVmean) within the boundary. The tumor-to-normal ratio (TNR), calculated as the maximum standardized uptake value (SUVmax) divided by the contralateral reference value, was also recorded. All patients underwent surgery (biopsy or tumor resection) targeting the tissue with high MET uptake. The Kaplan-Meier method was used to estimate the predictive value of each measurement. RESULTS: Grade II tumor was diagnosed in 12 patients (3 diffuse astrocytoma, 2 oligodendroglioma, and 7 oligoastrocytoma), grade III in 18 patients (8 anaplastic astrocytoma, 6 anaplastic oligodendroglioma, and 4 anaplastic oligoastrocytoma), and grade IV in 22 patients (all glioblastoma). TNR, MTV and TLMU were 3.1 ± 1.2, 51.6 ± 49.9 ml and 147.7 ± 153.3 ml, respectively. None of the three measurements was able to categorize the glioma patients in terms of survival when all patients were analyzed. However, when only patients with astrocytic tumor (N = 33) were analyzed (i.e., when those with oligodendroglial components were excluded), MTV and TLMU successfully predicted patient outcome with higher values associated with a poorer prognosis (P < 0.05 and P < 0.01, respectively), while the predictive ability of TNR did not reach statistical significance (P = NS). CONCLUSION: MTV and TLMU may be useful for predicting outcome in patients with astrocytic tumor.
  • Adaptor protein CRK induces epithelial-mesenchymal transition and metastasis of bladder cancer cells through HGF/c-Met feedback loop.

    英語, 研究論文(学術雑誌), We have previously reported that an adaptor protein CRK, including CRK-I and CRK-II, plays essential roles in the malignant potential of various aggressive human cancers, suggesting the validity of targeting CRK in molecular targeted therapy of a wide range of cancers. Nevertheless, the role of CRK in human bladder cancer with marked invasion, characterized by distant metastasis and poor prognosis, remains obscure. In the present study, immunohistochemistry indicated a striking enhancement of CRK-I/-II, but not CRK-like, in human bladder cancer tissues compared to normal urothelium. We established CRK-knockdown bladder cancer cells using 5637 and UM-UC-3, which showed a significant decline in cell migration, invasion, and proliferation. It is noteworthy that an elimination of CRK conferred suppressed phosphorylation of c-Met and the downstream scaffold protein Gab1 in a hepatocyte growth factor-dependent and -independent manner. In epithelial-mesenchymal transition-related molecules, E-cadherin was upregulated by CRK elimination, whereas N-cadherin, vimentin, and Zeb1 were downregulated. A similar effect was observed following treatment with c-Met inhibitor SU11274. Depletion of CRK significantly decreased cell proliferation of 5637 and UM-UC-3, consistent with reduced activity of ERK. An orthotopic xenograft model with bioluminescent imaging revealed that CRK knockdown significantly attenuated not only tumor volume but also the number of circulating tumor cells, resulted in a complete abrogation of metastasis. Taken together, this evidence uncovered essential roles of CRK in invasive bladder cancer through the hepatocyte growth factor/c-Met/CRK feedback loop for epithelial-mesenchymal transition induction. Thus, CRK might be a potent molecular target in bladder cancer, particularly for preventing metastasis, leading to the resolution of clinically longstanding critical issues.

    英語, 研究論文(学術雑誌), BACKGROUND: Clusterin is a cytoprotective chaperone protein involved in numerous physiological processes, carcinogenesis, tumor growth and tissue remodelling. The purpose of this study was to investigate whether clusterin (CLU), an antiapoptotic molecule, could be a potential predictor molecule for ovarian cancer and whether or not targeting this molecule can improve survival of ovarian cancer patients. METHODS: Clusterin expression was compared between ten primary and their recurrent tumors from same patients immunohistochemically. We analyzed prognostic significance of CLU expression in another 47 ovarian cancer tissue samples by immunohistochemistry. We used small interference RNA to knock down CLU in the chemo-resistant ovarian cancer cell lines. KF-TX and SKOV-3-TX, paclitaxel-resistant ovarian cancer cells, were established from parental KF and SKOV-3 chemo-sensitive cell lines, respectively. Either siRNA or second generation antisense oligodeoxynucleotide against CLU (OGX-011), which is currently evaluated in clinical phase II trials in other cancer s, was used to modulate sensitivity to paclitaxel (TX) in ovarian cancer cells in vitro. Cellular viability assay, FACS analysis and annexin V staining were used to evaluate the comparative effect of CLU knocking down in ovarian cancer cells. RESULTS: Immunohistochemical analysis of CLU expression in primary ovarian cancer tissue specimens and their recurrent counterparts from same patients demonstrated higher expression of CLU in the recurrent resistant tumors compared with their primary tumors. High expression of CLU by immunohistochemistry among 47 surgical tissue specimens of early-stage (stage I/II) ovarian cancer, who underwent complete cytoreduction as a primary surgery, significantly related to poor survival, while none of other clinicopathological factors analyzed were related to survival in this patient cohort. Secretory CLU (s-CLU; 60 KDa) expression was upregulated in TX-resistant ovarian cancer cells compared to parental cells. Transfection of siRNA or OGX-011 clearly reduced CLU expression. Cell viability assay, FACS analysis and annexin V staining demonstrated that targeting CLU expression by siRNA or OGX-011 sensitized ovarian cancer cells to TX. CONCLUSION: We conclude that CLU could be a potential molecular target to predict survival while targeting this s-CLU may improve survival of patients with ovarian cancer.

    がんの再発は、がん治療に耐性を示すがん幹細胞が生き残ることによって起きる。がんの根絶には、がん組織におけるがん幹細胞の誕生・生存機構の解明が必須であるが、がん幹細胞が微量なことに加えて、従来のポリスチレンdish上でのがん細胞単独培養法は生体内のがん組織環境と大きく乖離しており、真の解明に至っていない。研究代表者らは、近年、高強度ダブルネットワークゲル(DNゲル)上にがん細胞を播種すると、24時間以内に迅速にがん幹細胞が誘導されるリプログラミング(初期化)現象を見出した(Nat. Biomed. Eng., 2021)。当該技術を基盤として、本研究ではがん組織におけるがん幹細胞の誕生・生存機序の解明を目指す。
    令和3年度は、高頻度に再発を引き起こす肉腫の生体内環境を模倣するために、高強度DNゲルの作製技術と多孔質ゲルを得る凍結重合法を組み合わせて、高強度多孔質(ポーラス)ゲルを作製した。ポーラスゲルは、1st モノマーにアニオン性高分子NaAMPSを用い、2ndモノマーに中性高分子AAmを用いた。筋組織を模倣するため、細胞外基質としてフィブロネクチンを吸着後、GFPラベル筋芽細胞を播種し、細胞の接着や長期生存を検討した。AAmの濃度を変えることでポーラスサイズを調整し、さらに細胞の播種方法を改善することにより、ポーラスゲルの深部まで細胞が進展するよう3次元組織モデルを最適化した。このポーラスゲルをマウスの筋肉内に埋植すると、1週間以内に宿主細胞がゲル内に侵入して組織を復元した。一方、氷の成長方向を制御するフリーズキャスティング法を用いた凍結重合法により、筋組織を模倣した高度な配向構造を有するポーラスゲルの創製に成功した。

    (研究の骨格)本研究は、申請者が高機能ポリマーハイドロゲルを用いることで、極めて短時間にがん細胞のリプログラミングを誘導して、がん幹細胞を同定する方法見出したことにはじまる。これは従来のがん幹細胞分離同定法とは異なり、がんの種類を問わず24時間以内にがん幹細胞を同定することができる画期的な方法であり、本研究では、高機能ゲルのどのような物理学的因子ががん細胞の遺伝子発現変化を短時間で誘導するのかを検討し、高機能ゲルを基盤としたがん幹細胞診断法を開発し、さらにがん幹細胞標的治療薬を大規模スクリーニングにより創出するものである。(今年度の実績)「ゲル開発」プロジェクトでは、これまでの当該研究の結果から、陰性荷電を有するpoly-2-acrylamido- 2-methylpropanesulfonic acid (PAMPS) と中性荷電のpoly-N, N’- dimethylacrylamide (PDMAAm)にがん幹細胞誘導能が存在することが判明しており、とくにこれらのダブルネットワーク(DN)構造が重要であることが判明していた。さらに正と負の荷電両方有する両性荷電ゲルPCDME (poly-carboxymethyl -dimethyl-methacryloyloxy ethanaminium)もがん幹細胞誘導能を有することが判明していたが、当該年度の研究において負荷電を有するPNaSS(poly-sodium p-styrene sulfonate)のシングルネットワークゲルが、DNゲルより高いがん幹細胞誘導能を有することが明らかとなった。また、「臨床応用」のプロジェクトでは、従来検討されていなかった、ヒト肝臓がん(肝細胞がん)の細胞株を用いてDNゲルにより誘導した肝細胞がん幹細胞の解析から、ケモカイン受容体の1つであるCMKLR1が新規マーカーであることを発見した。

  • 電荷による細胞応答制御法の創出ーチャージハイドロゲルでウイルス感染症・がんを治す
    科学研究費助成事業
    2021年07月09日 - 2023年03月31日
    田中 伸哉
    (研究の骨格)医学の領域で感染症・がんは2大疾患であり、これらを制御することは喫緊の課題である。我々は最近、バイオマテリアルの1つであるハイドロゲルがヒト細胞に急速なゲノム変化を誘導することを見出した(Nat. Biomed. Eng, 5, 914-925, 2021)。本研究はこの技術を格段に発展させるもので、ハイドロゲルを用いて細胞周囲のチャージ(荷電状態)を変化させることで細胞のゲノム状態を制御し、1)ウイルスへの感染を防御し、また、2)がん幹細胞を誘導することで、がんの早期診断法およびがん幹細胞特異的治療薬を開発する。
    (今年度の実績)(1)チャージゲルによるウイルス増殖制御法の創出:陰性荷電を有するPAMPSゲルとPNaSSゲル、さらに正と負の荷電の両方を有する両性荷電ゲルPCDME上でウイルス感受性細胞VEROを培養し、COVID-19感染後にウイルス増殖を検討した。ウイルス核酸レベルで評価した場合、PAMPSとPNaSS上でウイルス増殖が亢進する一方、PCDMEゲル上では抑制される傾向が認められた。
    (2)チャージゲルによるがん幹細胞誘導:陰性荷電を有するAMPSと陽性荷電を有するAPTMAモノマーを様々な割合で配合したチャージハイドロゲルを作製し、患者由来膵癌初代細胞を培養した所、陽性にシフトしたチャージゲルに癌細胞は接着し、癌幹細胞マーカーの発現が亢進することが明らかとなった。

    がんの転移についてはこれまで多数の研究が実施されてきたが、転移先臓器で長年潜伏していたがん細胞が何をきっかけに覚醒・再増殖するのか、また解剖学的位置関係からは説明をつけにくい臓器に転移・再発する理由はなぜか、その詳細な分子メカニズムは未だ解明されていない。申請者らはこれまで、シグナル伝達アダプター分子Crkががんの増殖・接着・ 浸潤・転移の全てのステップにおいて重要な役割を果たしていること、また最近、Crkががん組織の多様性形成に関与すると共に、エクソソームを介して転移の成立と促進に寄与する という新知見を見出した。これは、アダプター分子が転移先臓器の環境を整備しがん転移を成立させることを示唆する画期的なデータである。本研究では、Crkによるエクソソームの多様性形成メカニズムを明らかにし、がん転移の臓器選択性とがん細胞の覚醒との関連性を解明する。
    当該年度は、ヒト浸潤性膀胱癌細胞株UM-UC-3の親株およびCrkノックダウン細胞から、超遠心法によりエクソソームを分離した。エクソソームに内包されている分子を、nano-LC MS/MS(蛋白質)で解析した所、受容体型チロシンキナーゼ、細胞内チロシンキナーゼ、細胞増殖因子、細胞外マトリックス、細胞接着分子、マトリックスメタロプロテアーゼなどが内包されていることが明らかとなった。これらの結果は、Western blottingによって確認された。各エクソソームを血管内皮細胞HUVECsに投与すると、UM-UC-3由来のエクソソームはHUVECsの細胞増殖能力、およびマトゲルへの浸潤能が行進することが明らかとなった。Crkノックダウン細胞由来のエクソソームはこれらの効果は認められなかった。

    子宮頸癌は若年発症が特徴で罹患率は増加傾向を示す。放射線照射が行われるが、個々の腫瘍反応性は異なり治療効果も様々である。放射線照射後再増殖腫瘍の分子メカニズムを解析することで個々の腫瘍の特性に応じた治療効果予測ができる可能性があるのではないかと考えた。これまでの研究結果から放射線照射後の耐性細胞ではHippo 経路を介したEMT関連分子及びstemness関連分子の発現誘導、EGFR, PDGFRのリン酸化が関与することがわかった。現在、Hippo経路あるいはEMT経路を抑えて放射線照射を行うことで悪性形質転化を抑制できるか検討中である。

    本研究は以下の発見・解明を行った。①間葉系細胞の軟骨に分化・再生過程においては、解糖系とミトコンドリア呼吸の振動に依存するATP振動がカルシウムイオン振動に誘導されて発生し、分泌の調節を介して軟骨凝集・組織再生を制御する。②DN ゲルが誘導する軟骨分化時にはActin構造の改変による細胞弾性率の上昇が、Insulinと比べて有意に早期に起こる。③DN ゲル誘導軟骨分化時の細胞内情報伝達機構に関して、BMP/TGF-βシグナル経路が特異的に活性化されており、またInsulin非依存的にIGF依存性シグナル伝達経路が活性化されている。④このゲルは液性因子のリザーバー機能を有する。

  • 癌治療薬探索を目指した新規スプライシングモニタリングシステム構築への挑戦
    科学研究費補助金(挑戦的萌芽研究)
    2012年 - 2012年
    田中 伸哉
    本研究はこれまで全く未知であったmRNAのスプライシングに基づく発癌メカニズムを明らかにし、その治療薬を探索するシステムを構築することを目的とする。
    具体的には多くのヒト癌の悪性化に関与することが判明しているシグナル伝達アダプター分子CRKに焦点をあて転移能の高いCRK-IIへの転換機構を明らかにする。CRKのスプライシングモニタリングシステムを構築し、CRKのスプライシングを制御する機構を分子レベルmicroRNAをスクリーニンし、これまでに全く未知のメカニズムを明らかにする。遺伝子発現は従来転写因子を中心とするエピジェネティックな解析が主流であり近年はmicroRNAが注目されているが、もう1つの重要なメカニズム1つであるスプライシング機構は解明が進んでおらず、疾患との関連、癌との関連では全く深い検討はなされていないのが現状である。
    今回我々はシグナル伝達アダプター分子CRKがスプライシングバリアントにより機能が異なる点に着目し新規のスプライシングモニタリングシステムを構築するものであり、これまでにない時間空間的なスプライシング情報を得ることができ、正常細胞と癌細胞のスプライシングの差を明確にする画期的なシステムとなることが期待される。
    本年度の研究においてヒトCRKゲノムをBACクローンより単離してその遺伝子配列を決定した。またCRKゲノムにGFPをN末端とC末端の2つの部分に分けて挿入し、スプライシングが生じるときにGFPの野生型の蛋白が発現するベクターをデザインした。またスプライシングによる生理作用をあらかじめ検討するためにCRK-IとCRK-IIをそれぞれ組み込んだ細胞を作成したところ、CRK-IIはepithelial mesenchymal transitionに積極的に関与することが明らかとなった。今後スプライシングとEMTの関連についても着目して研究を進める。

  • 滑膜肉腫幹細胞の同定と創薬基盤の確立
    科学研究費補助金(基盤研究(B))
    2011年 - 2012年
    田中 伸哉
    滑膜肉腫は若年成人の関節周辺に発生する悪性度の高い腫瘍であり有効な治療法は未だ確立されていない。
    本研究では根源的な治療法を開発するため、滑膜肉腫幹細胞を同定し腫瘍発生機構・病態を解明し、発癌メカニズムに基づく治療薬開発の基盤技術を確立する。発癌機構の解析は、①肉腫幹細胞の分離とマーカー分子の同定、② 滑膜肉腫キメラ遺伝子SYT-SSXによるクロマチンリモデリング測定システムの開発、③滑膜肉腫の腫瘍化に必須のシグナル伝達分子Crkによる転移・浸潤メカニズムの解明、の3つを柱とする。治療薬剤のリード化合物の探索は独自に開発した1分子特異的シグナル抑制薬剤スクリーニング法、2分子結合FRETイメージング法、分子構造に基づくin silico分子設計法を用いて、スクリーニング法の基盤を確立する。候補となる化合物は申請者らが確立した滑膜肉腫モデルマウスを改良し、臨床応用の可能性を含めて有効性を評価する。
    本研究では肉腫幹細胞、クロマチンリモデリング機構、HGF-Crkシグナルの3点に焦点をあて、SYT-SSXの癌化のメカニズムについて分子生物学的に包括的・総合的な理解を目指す。特に肉腫幹細胞はこれまで報告がほとんどなく、治療上極めて重要な発見となる。クロマチンリモデリングと発癌との関連については、近年急速に解析が発展している分野であるが、滑膜肉腫については癌化に必須であるSYT-SSXとhBRMとの結合は当研究室で発見されたものであり独創性が高い。

    2009年 - 2011年
    澤 洋文, 田中 伸哉
    本年度はJCウイルス(JCV)がコードする早期タンパク質であるT抗原(TAg)、および後期タンパク質であるVP1に着眼して研究を推進した。JCV感染細胞において、TAgの非特異的なDNA結合性が細胞周期に与える影響を検討するため、DNA結合性が低下もしくは増強するTAgの変異体を作成した。次に、これらの変異体を細胞に導入・発現させて細胞周期を解析した。野生型TAgを発現した細胞はG2/M期の細胞が増加していたが、DNA結合性が低下したTAg変異体を発現した細胞はG2/M期への細胞の集積は認められなかった。また、DNA結合性が増強しているTAg変異体を発現した細胞ではG2/M期に集積する細胞数が野生型よりさらに増加していた。本研究により、TAg発現による細胞周期のG2期停止の機構において、TAgが宿主細胞のDNAへ結合することが関与していることが明らかになった。また、JCV感染細胞でTAgの発現によって誘導されるG2期停止は効率的なウイルスDNAの複製に必須であることが判明した。次に、外郭タンパク質であるVP1内に6個存在するシステイン残基の変異体を作成して、JCVの粒子形成能を比較・検討した。本実験により、VP1タンパク質が互いに結合し5量体を形成すること、5量体の形成過程においてシステイン残基が必須であること、5量体の形成に続いて粒子形成が起こることが明らかになった。これま...

    谷野 美智枝, 別役 智子, 田中 伸哉
    昨年、我々は特発性肺線維症患者の外科病理標本を用いて、免疫染色を施行し、CRKI/II及びCRKの下流蛋白であるDock180,C3Gが肺胞上皮細胞及び間質の線維芽細胞に強く発現することを示し、肺線維症における病的線維化の過程において、肺胞上皮細胞及び線維芽細胞におけるCRKの発現を介したシグナル伝達が関与している可能性を示した。本年度は肺胞上皮細胞に着目しin vitroの系を用いて、CRKを強発現することによって引き起こされる線維化へのメカニズムを検討した。特に、上皮-間葉移行に着目し、以下の方法を用いて実験を行った。肺胞上皮細胞株としてA549細胞を用い、レトロウィルスベクターを使ってCRKI高発現株、CRKII高発現株を樹立し、コントロール細胞と比較検討を行った。線維化において中心的な役割を果たしているサイトカインであるTGFβ1を5ng/mlで刺激し、48,72時間後にmRNA及び蛋白を抽出した。EMTに関与する転写因子であるslug及び間葉系マーカーであるvimentinのmRNA発現量をsemi quantitative RT-PCR法を用いて測定した。また、肺線維化部分で高発現しているMMP-2,9のmRNAの発現をsemi-quantitative PCR法を用いて測定し、上皮性マーカーであるE-cadherin,間葉系マーカーであるfibronectinの...

    これまでの研究で、アダプター分子Crkの癌化における役割を解析し、癌腫、肉腫、脳腫瘍など様々なヒト癌細胞株を用いてsiRNA法にてCrk knockdown細胞株を樹立した。何れの種類のCrk knockdown細胞においても、接着能、浸潤能、足場非依存性増殖能、in vivo造腫瘍能など、癌細胞の悪性化を示す指標に、著明な減少がみられ、Crkはヒト卵巣癌、軟部肉腫、脳腫瘍において、悪性化に必須の分子であることが明かとなった(Oncogene, 25,2006 : Mol.Cancer Res., 7,2006)。また、Crkの癌化におけるシグナル伝達メカニズムを詳細に解析するために、NMRを用いた構造解析を行い(Nature Struct.Mol.Biol., 2007)、昨年度は、Crkのシグナル伝達を抑制する薬剤開発する前段階として、単一の遺伝子変化に対応する薬剤スクリーニングの系を確立した(BBRC,373,2008)。この系を用いてCrkを発現させたアストロサイトに対して、dual luciferase assayを行い96wellプレートで薬剤をスクリーニングして、Crkシグナル阻害薬を同定した。以後の研究では、真にCRKシグナルを抑制する薬剤か否かを個別に判定していき臨床応用可能か否かをin vivoの系で解析していきたい。また、今年度の研究において癌細胞の浸潤...

    本研究は細胞側因子と相互作用し、細胞内の物質輸送に影響を与えるJCウイルス(JCV)のagnoproteinがオリゴデンドロサイトの機能障害を惹起させる。」という作業仮説を立て、agnoproteinを中枢神経に発現させるトランスジェニックマウスを作製し、JCV感染によって生じる、多発性硬化症とは異なった機序で発症する非炎症性の脱髄のモデルを確立し、ウイルス感染後の脱髄病変の形成過程の機序を詳細に検討することを目的として以下の実験を行った。平成20年度はマウスのスクリーニングを行うにあたり、従来行われていたSouthern blottingによる解析ではなく、mouseの血液から直接、導入遺伝子を検出するFTA paperを用いたPCRの系を使ってsample採取当日に結果を得ることの出来る系を構築した。作製したスクリーニングの系を用いて、agnoproteinおよびlate proteinのトランスジェニックマウスの子孫およびタモキシフェン反応性のCreリコンビナーゼを発現しているトランスジェニックマウスを交配させ、タモキシフェン投与によりJCウイルスのagnoproteinもしくはlate proteinをオリゴデンドロサイトに発現させるダブルトランスジェニックマウスを作製した。今後はタモキシフェン投与法の条件を決定し、タモキシフェン投与により脳のオリゴデンドロサイトにa...

    田中 伸哉, 西原 広史
    本研究ではアダプター分子Crkの癌化における役割を解析し、癌腫、肉腫、脳腫瘍など様々なヒト癌細胞株を用いてsiRNA法にてCrk knockdown細胞株を樹立した。何れの種類のCrk knockdown細胞においても、接着能、浸潤能、足場非依存性増殖能、in vivo造腫瘍能など、癌細胞の悪性化を示す指標に、著明な減少がみられ、Crkはヒト卵巣癌、軟部肉腫、脳腫瘍において、悪性化に必須の分子であることが明かとなった(Oncogene,25, 2006:M01. Cancer Res.,7, 2006)。また、Crkの癌化におけるシグナル伝達メカニズムを詳細に解析するために、NMRを用いた構造解析を行ったところ、Crk-Iはflexibleな分子で恒常的にシグナル標的分子と結合しているが、Crk-IIは、Grb2などのアダプタ一分子とは異なり、3つのSH領域がコンパクトな構造をとっており、この構造が2つのSH3領域の間にある15アミノ酸によって制御されることが判明し、この領域をISC (inter SH3 core)と命名した。ISCの変異体は、標的分子への親和性が回復し、また、細胞増殖能もCrk-Iと同様のレベルまで増加した。したがって、Crk-IIのcompactなstructureがシグナルの制御に関与することが判明した(Nature Struct. Mol. Biol...

    田中 伸哉, 澤 洋文, 三浪 明男, 赤城 剛, 澤 洋文, 三浪 明男
    滑膜肉腫は長年原因不明の悪性肉腫であったが、1994年にClarkらがキメラ遺伝子SYT-SSXを同定したことから分子生物学的解析が急速に展開してきた(Clark, J., et al., Nature Genetics, 1994)。北大の当該研究室においては、平成13年度-平成14年度までの基盤研究(B)の成果としてSYT-SSXが癌遺伝子として機能することが細胞レベルで初めて証明されたが(Nagai, M., et al., PNAS, 2001)、本研究は、それまでの成果を発展させるため計画され、公募により科学研究費補助金の支援を受けたものである。本研究において、SYT-SSXがクロマチンリモデリング因子BrmばかりでなくBRGとも結合し機能することが明かとなり(Genes Cells, 9,2004)、SYT-SSXがp21を誘導することでcellular senescenceを引き起こすことが証明された(Oncogene, 24,2005)。また滑膜肉腫細胞の増殖に関しては、IGF2による増殖刺激を伝達することが示された(Oncogene, 25,2006)。さらにシグナルアダプター分子Crkをノックダウンすることによって、滑膜肉腫細胞株の癌化能が著明に低下することが判明した(Mol.Cancer Res., 7,2006)。本研究は、SYT-SSXを介する癌化の...

    田中 伸哉, 西原 広史
    【目的】本研究では、細胞癌化とユビキチン化に焦点をあててその詳細なメカニズムの解析を行った。具体的には、シグナル伝達アダプター分子CRKを介する癌化のシグナル伝達機構の中でユビキチン化の受ける可能性のある分子を検討し、ユビキチン化を可視化する事を試みた。【方法と結果】(i)CRK自体が人の癌化に必須の分子であることをsiRNAを用いた実験で証明し報告した(Linghu, H., et al., Oncogene,2006,in press)。ヒト卵巣癌細胞にてCRKをノックダウンすることで細胞癌化能が著明に低下し、特に卵巣癌の腹腔内播種は完全に抑制された。(ii)次にCRKを介する細胞癌化機構の中でSH3領域の標的分子である低分子量G蛋白質活性化因子DOCK180がユビキチン化を受けることを見出した(Makino, Y., et al., JCS,119,923-932,2006)。さらにこのDOCK180のユビキチン化はDOCK180のSH3領域の標的分子であるElmo1によって抑制される事で、細胞の局所においてDOCK180の量が制御されることでRacの活性が制御されることが示された。さらに、我々は現在ELMO1がチロシンリン酸化を受ける事を見出しており、その特異的なチロシン残基を1箇所同定しており、現在その機能解析を行っている。(iii)YFP-DOCK180とCFP-...

    長嶋 和郎, 田中 伸哉, 澤 洋文
    進行性多巣性白質脳症(progressive multifocal leukoencephalopathy:PML)はポリオーマウイルスに属する2本鎖環状DNAウイルスであるJCウイルス(JCV)が原因である。しかしながらJCVがヒト脳の脱髄疾患であるPMLを引き起こす詳細なメカニズムは不明であり、根治的な治療法は全くない。治療法確立の基礎として、我々はJCVの感染および増殖メカニズムを解明するために、細胞側の受容体での選択性、および核内転写調節過程での特異性に関与する分子を同定することを試み、JCVの吸着から転写までの機構を明らかにした。1)semi-quantitative PCR法を基にしたJCV entry assayを用いて、細胞膜でのJCV受容体は種を超えて幅広く存在している分子であることが判明した。2)受容体の主分子としてはシアル酸を複数個持つ糖脂質および糖蛋白であり、その一候補としてintegrinが同定された。また、副分子としてスルファチドの関与が認められた。3)ウイルス側の結合分子は外核蛋白VP1であった。VP1にてintegrinと結合したJCVは、clathrin pathwayを経て10分後にはvirionの形態で核内に到達していた。4)転写調節因子としてこれまで機能が不明であったJCV後期蛋白の一つであるagnoproteinおよびHTLV-I T...

    1998年 - 1999年
    田中 伸哉
    研究代表者は本研究助成において、申請時の目的を達成した。すなわちR-RasがC3Gの基質として機能し、Junキナーゼ(JNK)を活性化しv-Crkの癌化に関与することを見出し報告した(Mochizuki,N.,et al.,J.Biol.Chem.,2000,in press)。研究代表者はこれまでニワトリ肉腫のウイルスのコードする癌遺伝子v-Crkの癌化のメカニズムの解明を目的に研究を行ってきており、本研究においてはR-Rasがv-Crk/C3G複合体からのシグナルを媒介し癌化に関与することを明らかにした。V-CrkはSH2/SH3領域からなるアダプター分子でありそれ自身は何ら酵素活性を持っていないにもかかわらずチロシンキナーゼ活性を上昇させて細胞癌化を誘導するが、そのメカニズムは不明であった。我々は独自にv-Crk結合分子C3Gを単離し、その解析を進めていたが1997年までの段階でv-CrkはC3Gを介してJNKを活性化し細胞癌化に関与することを報告していた。しかしながらC3GのJNK活性化に関与する基質は不明であった。本研究では一連のsmall G蛋白を調べることによって、R-RasがC3Gの基質として機能しJNKを活性化することが明らかとなった。具体的には、活性化型R-Ras-V38は一過性発現によって293T細胞において、JNKを活性化し、野生型R-Ras-WTのJ...

    長嶋 和郎, 鈴木 宏明, 田中 伸哉, 澤 洋文
    我々はratにmethylmercury chloride(MMC)を投与することにより誘発される小脳顆粒細胞層障害のモデルを確立した。このモデルを用いて最初に電子顕微鏡による観察、TUNEL法、電気泳動によるDNA fragmentationの検出等により、この障害がアポトーシスであることを確認した。さらに小脳顆粒細胞でのアポトーシスに好発部位があることも証明した。これらのアポトーシスの機序を分子レベルで解明するために、種々のapoptosis関連蛋白(BDNF,Trk B,Fas ligand,RIP,Akt,Bad,Bc1-2,Caspase9,Caspase3,CAS,TIAR)の発現をWestern blotにて検索した。またPurkinje cellの機能を反映している蛋白Calbindin Dの抗体を用いた免疫染色によりPurkinje cellの障害程度を評価した。さらにMMC投与によるrat脳での遺伝子の発現の変化の検索を行った。その結果apoptosis関連蛋白はMMC投与後24日目に変化しているものが多く、全体の傾向としては中毒初期ではapoptosisに関して抑制的に働くBDNF、Trk Bは増加しており、促進的に働くRIP、CAS、Fas ligand、Bad、Caspase9は減少していた。またCalbindin Dの染色性についてはMMC投与によ...

    1.Clontech(Palo Alto,CA)社のyeast one-hybrid system)を用いてJC virus NF-1領域に特異的に結合する蛋白を同定した。NF-1配列を用いたスクリーニングで30個の陽性クローンから4個はこれまでにdata baseに登録されていない未知遺伝子であったためにこのDNA配列を確認し、NF-1/Xをcloningし、その発現が脳に多いことを示した。2.ヒトに無症候性に感染し、常時尿に排泄されている型Archetype JC virusであるCY株(調節領域が原始型)がCOS-7細胞で増殖することを見いだし、この細胞を用いた解析系を樹立した。Mad-1(調節領域がPML型)と調節領域をCYに変えたキメラウイルスCY/Mad-1で感染性を調べ、cellular tropsimに調節領域が関与していることを示した。3.Microinjection法により非感受性細胞であるCOS7でも細胞膜を越えてvirusを注入するとvirusの増殖が見られることから、virus感染に細胞膜因子が存在することを示唆した。4.過去2年間に日本国内にて発症が確認されたPMLの5症例のregulatory regionを解析し、4例のPML型と1例のArchetype JCの症例を見い出し、報告した。またPMLの髄液を用いたPCRによる診断方法を確立した。
