English, Scientific journal, BACKGROUND: Cachexia and sarcopenia are prevalent, inflammation-linked syndromes in chronic liver disease that worsen outcomes. To our knowledge, their coexistence in a single chronic liver disease cohort has not been systematically examined. In this study, we evaluated the prevalence, clinical features and prognostic impact of cachexia and sarcopenia-alone and combined-in chronic liver disease. METHODS: We retrospectively screened 776 patients with liver cirrhosis (LC) and/or hepatocellular carcinoma (HCC) at Hokkaido University Hospital (August 2014-May 2025). The inclusion criteria were grip strength, CT-based muscle mass and complete clinical data, yielding 307 patients; 469 did not meet one of the inclusion criteria. Cachexia was determined following the Asian Working Group for Cachexia criteria, and sarcopenia was determined following Japan Society of Hepatology guidelines. Patients were grouped as no cachexia/sarcopenia, cachexia only, sarcopenia only or cachexia+sarcopenia. The outcomes were overall survival, time to liver-related events and time to readmission (Kaplan-Meier and Cox-proportional models). RESULTS: Among 776 patients, 307 were included in the final-analysis. Of 307 patients, 206 (67.1%) were male, the median age was 70 years (range, 19-90 years), 262 patients (85.3%) had LC and 188 patients (61.2%) had HCC. The patients were grouped as no cachexia/sarcopenia (213; 69.4%), cachexia only (54; 17.6%), sarcopenia only (17; 5.5%) and cachexia+sarcopenia (23; 7.5%). The combined group compared with the others had the lowest body mass index, psoas-muscle-index and grip strength (all p < 0.001). Overall survival (OS), liver-related events, LC progression and readmissions were compared between 246 patients with and without cachexia or sarcopenia, after excluding those who visited the hospital on or after July 2023 and had ≤ 3 months of follow-up. OS was shorter in the cachexia only (median 61.8 [95% CI 40.90-not reached (NR)] months, p = 0.046) and cachexia+sarcopenia (median 59.6 [95% CI 14.26-NR] months, p = 0.027) groups than in the no cachexia/sarcopenia group. Multivariable analysis showed that cachexia+sarcopenia (hazard ratio 2.48, p = 0.010), HCC (hazard ratio 3.40, p < 0.001) and diabetes mellitus (hazard ratio 1.80, p = 0.013) independently predicted mortality. The combined group compared with the other groups had a shorter time to liver-related events and readmission. CONCLUSIONS: The coexistence of cachexia and sarcopenia-rather than either alone-can be used as an indicator for identifying patients with chronic liver disease at the highest risk of poor outcomes. Concurrent assessment and early, targeted interventions may improve outcomes in this population. - Topical amnion‐derived mesenchymal stem cell conditioned medium attenuates chronic ultraviolet B‐induced skin photodamage in hairless mice

English, Scientific journal, Self-expandable metallic and plastic stents have been used for biliary tract injuries, but they are not entirely adequate as treatments. This study investigated the potential of our novel self-expandable bioabsorbable covered stent (SEBCS) to treat bile duct injuries. We developed a novel SEBCS by covering a self-expandable bioabsorbable stent with a bioabsorbable tube. Five pigs underwent laparotomy after being placed under general anesthesia. A 5-mm incision was made in the extrahepatic bile duct, followed by the insertion of an SEBCS. Postoperatively, hepatobiliary enzyme levels were measured. At 10 weeks postoperatively, a histological evaluation of the injured area and cholangiogram were performed. The SEBCS was successfully inserted into the extrahepatic bile ducts of all animals. The histological evaluation at 10 weeks postoperatively showed epithelial regeneration with numerous peribiliary glands, including at the injury site. Cholangiography revealed no stenosis in the injured area. Hematological and biochemical analyses revealed mild elevation of biliary enzyme levels on day 10 postoperatively compared with preoperative levels; these levels returned to preoperative values by week 10. This novel SEBCS technique demonstrated the potential to regenerate bile ducts at the site of extrahepatic bile duct injury and may be a promising endoscopic treatment for biliary tract injuries. - Serum fibroblast growth factor 21 is a novel biomarker of cachexia in chronic liver disease.

English, Scientific journal, BACKGROUND: Cachexia is associated with poor prognosis in chronic liver disease (CLD), yet robust predictors remain poorly defined. This study examined clinical factors and serum biomarkers associated with cachexia in patients with CLD. METHODS: We analyzed 356 of 526 patients with CLD who had complete cachexia assessment and available stored serum samples. In a discovery cohort (n = 240; Aug 2014-Jun 2023), serum fibroblast growth factor 21 (FGF21), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were measured. Multivariable logistic regression and receiver operating characteristic analyses were used to identify independent predictors and optimal cutoff values. Findings were subsequently evaluated in an independent validation cohort (n = 116; Jul 2023-May 2025). RESULTS: Median age was 68 years (range 19-90), 65.8% of participants were male, and 24.6% had cachexia, which independently predicted worse overall survival (hazard ratio 1.64; 95% CI 1.03-2.62; p = 0.038). Patients with cachexia had higher serum FGF21 concentrations than those without cachexia (median, 292 vs. 177 pg./mL; p = 0.002), whereas IL-6 and TNF-α levels did not differ significantly between groups. FGF21 was the only biomarker independently associated with cachexia (odds ratio, 1.71; 95% CI, 1.10-2.66; p = 0.016). Advanced Child-Pugh class and platelet count were identified as additional independent clinical predictors. CONCLUSION: Serum FGF21 independently predicts cachexia in CLD and may facilitate earlier identification of at-risk patients, enabling timely intervention to improve clinical outcomes. - 消化器内視鏡医が挑む,産学官連携によるデバイス開発の最前線 現状とそこから見える課題

English, Scientific journal, BACKGROUND: Hepatocellular carcinoma (HCC) remains a leading cause of cancer-related mortality. Although the atezolizumab/bevacizumab regimen demonstrated impressive efficacy in the IMbrave150 clinical trial, long-term outcomes, particularly 3-year overall survival (OS), remain unestablished because of limited follow-up. Long-term outcomes have been reported for the tremelimumab/durvalumab combination, highlighting the need for comparable data on atezolizumab/bevacizumab. We aimed to elucidate the 3-year OS in patients with unresectable HCC (uHCC) treated with atezolizumab plus bevacizumab. METHODS: This retrospective multicenter study included patients with uHCC who received atezolizumab/bevacizumab. Among the 506 patients treated at the participating institutions, only those who initiated therapy between October 2020 and January 2022 were included. Comprehensive clinical, laboratory, and imaging data were collected, and the patients were followed up until March 2025. RESULTS: A total of 257 patients were analyzed, with a median follow-up of 48.23 months (range, 36.23-53.60 months). The 2- and 3-year OS rates were 39.2% and 25.3%, respectively. Among patients meeting the IMbrave150 criteria, the 3-year OS rate was 31.6%. Multivariate regression analysis identified baseline alpha-fetoprotein level > 116 ng/mL (odds ratio [OR] 0.41; 95% confidence interval [CI] 0.20-0.84; p = 0.015) and modified albumin-bilirubin grade 1-2a (OR 2.50; 95% CI 1.18-5.32; p = 0.017) as significant factors associated with 3-year OS. CONCLUSIONS: In a real-world setting, the 3-year OS for uHCC patients treated with atezolizumab/bevacizumab was 25.3%, rising to 31.6% among those meeting the IMbrave150 criteria. Survival outcomes underscore the clinical value of atezolizumab/bevacizumab in improving long-term prognosis and guiding first-line treatment decisions for patients with unresectable HCC. - Cirrhotic Cardiomyopathy: Prevalence and Clinical Impact on Liver Cirrhosis Outcomes.

English, Scientific journal, AIM: Cirrhotic cardiomyopathy (CCM) is a significant complication of liver cirrhosis; however, its prevalence and impact in Asian populations remain unclear. The aim of this study was to assess the prevalence of CCM in Japanese patients with liver cirrhosis and to evaluate its impact on clinical outcomes. METHODS: In this retrospective study, 80 patients with liver cirrhosis confirmed using transient elastography (liver stiffness ≥ 12.5 kPa) were included. Study was performed at Hokkaido University Hospital between January 2014 and April 2024. CCM was diagnosed using the 2019 Cirrhotic Cardiomyopathy Consortium criteria. Subsequently, patient characteristics, survival, and the incidences of decompensation and cardiovascular events were analyzed. RESULTS: The prevalence of CCM was 46.3% (37/80), with 78.4% of patients with CCM showing isolated systolic dysfunction based on global longitudinal strain. Patients with CCM were significantly older, had lower serum ammonia and bilirubin levels, and had higher platelet counts. CCM was associated with a significantly higher incidence of decompensation events (hazard ratio 3.97, 95% confidence interval 1.64-9.61, p = 0.003) and was an independent risk factor for decompensation in the multivariate analysis (hazard ratio 3.24, 95% confidence interval 1.29-8.11, p = 0.012). Patients with and without CCM showed no significant differences in overall survival or cardiovascular events. CONCLUSIONS: CCM is prevalent among Japanese patients with liver cirrhosis and is associated with an increased risk of hepatic decompensation. These findings highlight the importance of cardiac evaluation in patients with cirrhosis and suggest that CCM should be considered in the management of liver cirrhosis to improve patient outcomes. - Sa1178: EXTRACELLULAR VESICLES OBTAINED FROM AMNION-DERIVED MESENCHYMAL STEM CELLS PREVENT ESOPHAGEAL STRICTURE AFTER ENDOSCOPIC SUBMUCOSAL DISSECTION IN PIGS

English, Scientific journal, BACKGROUND & AIMS: Fibroblast growth factor 21 (FGF21) is a crucial regulator of cell metabolism. Tumour-secreted FGF21 has shown immune-checkpoint factor functions, and high FGF21 levels are associated with a poor prognosis for patients. However, its prognostic value and impact on treatment response in patients with hepatocellular carcinoma (HCC) treated with immune-checkpoint inhibitors (ICIs) remain unclear. Thus, this study investigated the potential of high FGF21 levels as a prognostic marker and whether traditional ICI-based therapy can improve the prognosis of patients with high FGF21 levels. METHODS: In this retrospective multicentre study, patients with unresectable HCC who received atezolizumab/bevacizumab in the NORTE study group (n = 117) were classified into high (≥915 pg/ml; n = 29) and non-high (n = 88) FGF21 groups. For validation, we investigated patients treated with atezolizumab/bevacizumab in an independent cohort (n = 285). Overall survival, progression-free survival, and treatment response were compared between patients with and without high baseline FGF21 levels. RESULTS: The median overall survival (p <0.001) and progression-free survival (p = 0.045) were significantly shorter in the high FGF21 group than in the non-high FGF21 group. Independent cohort analysis validated these results. In the overall cohort, the median progression-free survival (5.75 vs. 8.84 months; p = 0.027) and median overall survival (14.13 vs. 22.08 months; p <0.001) were significantly shorter in the high FGF21 group than in the non-high FGF21 group. The durable response (≥6 months) + complete response rate was significantly decreased in the high FGF21 group (p = 0.045). No patient with a high FGF21 level achieved a complete response, whereas this was achieved in 4.1% (13/319) of patients with non-high FGF21 levels. Multivariate Cox regression analysis identified high baseline serum FGF21 as an independent poor prognostic factor for overall survival (hazard ratio 2.20, p <0.001). CONCLUSIONS: Serum FGF21 may be a robust, non-invasive prognostic and treatment response marker for unresectable HCC treated with atezolizumab/bevacizumab. IMPACT AND IMPLICATIONS: FGF21 has been reported to act as a secreted immune-checkpoint factor, and elevated levels of FGF21 are associated with a poor prognosis in patients with HCC. It is not fully understood whether ICIs can overcome the impact of high FGF21 levels on the shortened prognosis of patients with HCC. In this multicentre retrospective study, patients with HCC and high baseline levels of serum FGF21 who received atezolizumab/bevacizumab treatment exhibited a significantly shorter overall survival and shorter progression-free survival. These findings suggest serum FGF21 as a robust prognostic marker and an indicator of treatment response in unresectable HCC treated with ICI-based therapy. These findings could be crucial for the implementation of personalised treatment strategies for unresectable HCC. However, identifying optimal therapeutic options for patients with unresectable HCC and high serum FGF21 levels remains an urgent and critical clinical issue. - Extracellular matrix modulating effects of amnion‐derived mesenchymal stem cells on aging skin wounds in α‐Klotho knockout mice

English, Scientific journal, AIM: Wounds in the elderly are frequently recalcitrant and chronic as a result of the effects of skin aging and associated complications. The objective of this study is to utilize an α-Klotho knockout (KO) mice wound model to assess the capacity of amnion-derived mesenchymal stem cells (AMSCs) to facilitate wound healing in aging skin. METHODS: AMSCs were applied topically to the wound after extraction and gelatinization of the conditioned medium (CM). Animal experiments were performed with two distinct mouse strains: α-Klotho KO mice and wild-type mice. Full-thickness skin defect models with a diameter of 8 mm were created by incising the skin on the left and right sides of the dorsum. On day 8 after wound creation, the mice were sacrificed, and wound tissue was collected for analysis through histological and immunohistochemical evaluations, as well as through quantitative polymerase chain reaction. RESULTS: The topical application of CM gel to wounds of α-Klotho KO mice demonstrated that wound healing was significantly higher than that observed in control, reaching the wound closure rate of wild-type mice on day 8. Additionally, gene expression analysis of wound tissue indicated that AMSC-CM may regulate extracellular matrix formation and fibrosis. Moreover, histological analysis indicated that AMSC-CM may facilitate wound contraction of aging skin wounds of α-Klotho KO mice by inducing myofibroblast differentiation and promoting granulation and collagen formation, which are the primary components of the extracellular matrix. CONCLUSIONS: AMSC-CM may facilitate wound healing in aging skin of α-Klotho KO mice by regulating the extracellular matrix.

English, Scientific journal, AIM: Atezolizumab/bevacizumab is a first-line therapy for unresectable hepatocellular carcinoma (HCC). Among several adverse events, grade ≥2 proteinuria is considered a significant adverse event that may cause bevacizumab interruption. Studies have shown that proteinuria might predict improved prognosis, although data are scarce and the association remains controversial, and the mechanisms and predictive factors remain unclear. We aimed to clarify these. METHODS: In this multicenter retrospective study, we screened patients with HCC treated with atezolizumab/bevacizumab. The prognostic impact of grade ≥2 proteinuria was examined in patients with proper clinical data and preserved serum for growth factor analysis. For biomarker analysis predicting proteinuria, baseline serum vascular endothelial growth factor (VEGF)-A, VEGF-C, and VEGF-D levels were analyzed. RESULTS: This study included 75 patients, and 32 (42.7%) experienced grade ≥2 proteinuria. No significant differences were observed between those with or without proteinuria, except for aspartate transaminase and alanine transaminase levels. Time-dependent Cox proportional hazards analysis revealed that grade ≥2 proteinuria was significantly associated with better prognosis (hazard ratio 0.221; 95% confidence interval 0.082-0.592; p = 0.003). In biomarker analysis, low baseline serum VEGF-C and VEGF-D levels were significantly associated with proteinuria, and multivariate analysis demonstrated that baseline serum VEGF-D level was significantly associated with grade ≥2 proteinuria (hazard ratio 0.101; 95% confidence interval 0.029-0.357; p < 0.001). CONCLUSIONS: Grade ≥2 proteinuria in patients with unresectable HCC treated with atezolizumab/bevacizumab indicates a better prognosis, and baseline serum VEGF-D levels can help predict its occurrence. These findings can help in managing adverse events and prognosis in advanced HCC treated with atezolizumab/bevacizumab. - A novel mouse model for studies of burn wound conversion using a top hat–shaped brass template

English, Scientific journal, INTRODUCTION: The pathophysiology of burn wound conversion is not fully understood. Animal models are needed to elucidate the underlying mechanisms and develop treatments. Here, we established a new reproducible mouse model that simulates this process, thereby facilitating studies of burn wound conversion. MATERIALS AND METHODS: After anesthesia and depilation, 75 mice were randomly assigned to 5-, 15-, and 25-s contact groups, and a top hat-shaped brass template was heated in boiling water and applied to the lateral abdomen. The wound area was calculated from photographs and the percentage of the surviving area was determined. Histological samples were collected 1-96 h after injury. RESULTS: A 15-s contact time produced the desired 50 %-75 % interspace necrosis at 96 h after injury. The 5-s contact group had a mostly preserved interspace, while the 25-s contact group exhibited near-complete necrosis. Histologically, significant differences between the 5- and 15-s contact groups were seen in cutaneous appendage denaturation and panniculus carnosus denaturation early after injury. CONCLUSION: Exposing mice to the heated template for 15 s provides a reproducible model for studying burn wound conversion mechanisms and treatments, facilitating further elucidation of burn pathophysiology and evaluation of therapies to prevent burn wound conversion. - Efficacy of Rikkunshito on Chemotherapy-Induced Nausea and Vomiting in Patients With Uterine Corpus or Cervical Cancer Treated With Cisplatin-Based Regimen-Placebo-controlled, Double-Blind, Randomized Confirmatory Study (JORTC-KMP03).

English, Scientific journal, BACKGROUND: The current standard treatment for chemotherapy-induced nausea and vomiting (CINV) with standard antiemetics is insufficient. Rikkunshito, a Japanese traditional herbal medicine, has been shown to improve cisplatin-induced anorexia and functional dyspepsia, and our exploratory study found that rikkunshito has an additive beneficial effect on CINV in patients with uterine corpus and cervical cancer receiving cisplatin containing chemotherapy (JORTC KMP-02). METHODS: One hundred eighty patients with uterine corpus or cervical cancer who were scheduled to receive treatment with a cisplatin based regimen as initial chemotherapy were enrolled across 17 Japanese institutions. Patients were randomized with a 1:1 equal allocation ratio to the rikkunshito group or placebo groups and given oral administration on days 1 to 5 with standard antiemetics (granisetron, aprepitant, and dexamethasone). The primary endpoint was complete response (CR; no vomiting or rescue medication) during the delayed phase (24-120 hours after cisplatin treatment). The secondary endpoints were complete control (CC; CR without significant nausea) and total control (TC; CR without nausea) rates during the overall (0-120 hours), acute (0-24 hours), and delayed phases, as well as the CR rate during the overall and acute phases, time to treatment failure, degree of nausea and appetite during the overall phase, and adherence to the intervention. RESULTS: The CR rate in the delayed phase was similar between the rikkunshito group and control groups (50.6% vs 58.9%, P = .2631), as were the secondary endpoints: CR rates in the overall and acute phases, CC and TC rates in the overall, acute, and delayed phases, degrees of nausea and appetite, and time to treatment failure. CONCLUSION: Rikkunshito had no additive effect on CINV prevention in patients with uterine corpus or cervical cancer who were treated with a cisplatin based regimen and standard antiemetics.

English, Scientific journal, INTRODUCTION: Cis-diamine-dichloro-platinum (II) (cisplatin) is a widely prescribed anticancer drug known to induce severe side effects, including skeletal muscle atrophy. As muscle atrophy negatively impacts the prognosis and survival of cancer patients, elucidation of its pathogenesis and development of preventive and treatment methods is important. Hochuekkito (HET), a Japanese Kampo medicine, has been reported to improve decreased physical activity and muscle weight in various animal models, but not in cisplatin-induced muscle atrophy. Therefore, this study aimed to clarify the characteristics of cisplatin-induced muscle atrophy and the therapeutic effects of HET, especially with emphasis in the recovery phase. METHOD: Eight-week-old male C57BL/6J mice were administered with cisplatin (3 mg/kg/day, intraperitoneally) from Day0 to Day3 and provided HET-containing food from 2 weeks before cisplatin administration until Day14. Muscle weight and performance were evaluated and the underlying mechanisms were investigated by using gene expression, immunohistochemistry, and microRNA (miRNA)-sequence analyses. RESULTS: Cisplatin administration continued to reduce gastrocnemius muscle weight until Day14, even after recovery from transient decrease in food intake and body weight and was accompanied by decreased locomotor activity and grip strength, presumably due to the continuous suppression of the mRNA expression of Myogenic differentiation 1. Although HET did not suppress the activation of muscle protein degradation or increase myogenic regulatory factor expression, it restored decreased locomotor activity and gastrocnemius muscle weight by inducing an increase in the weight of the red muscle region, which contains slow-twitch fibers. Immunohistochemical analysis showed that red muscle slow-twitch fiber cross-sectional area was increased by HET treatment. The levels of miRNAs involved in muscle atrophy and aging, such as miR-29a/b and miR-34a, were increased by cisplatin; conversely, HET increased the expression of miR-1a-1 and miR-1a-2, which reportedly enhance muscle differentiation, and miR-206, which enhances slow muscle fiber differentiation and thickening. CONCLUSION: HET increased locomotor activity and muscle weight in cisplatin-induced muscle atrophy model mice, probably by enhancing myogenesis in slow-twitch fibers, which was related to miRNA expression changes. Thus, HET may be useful in treating cisplatin-induced muscle atrophy. - Thymidine Phosphorylase Imaging Probe for Differential Diagnosis of Metabolic dysfunction-associated Steatohepatitis.

English, Scientific journal, PURPOSE: Metabolic dysfunction-associated steatotic liver disease (MASLD) comprises simple steatosis (SS), which has a low risk of mortality, and metabolic dysfunction-associated steatohepatitis (MASH), which can progress to liver cirrhosis and hepatocellular carcinoma. Because differentiation between MASH and SS is the most important issue in the diagnosis of MASLD, the establishment of noninvasive diagnostic methods is urgently needed. In this study, we evaluated the potential of [123I]IIMU, a thymidine phosphorylase (TYMP) targeted SPECT imaging probe, for differential diagnosis of MASLD in a preclinical animal model. PROCEDURES: SS and MASH mice were prepared by feeding db/db mice with a standard diet and a methionine/choline-deficient diet, respectively. Control mice were prepared by feeding m/m mice with a standard diet. TYMP expression in the liver was evaluated by RT-PCR, western blotting, and immunohistochemistry. The biodistribution of [125I]IIMU in the three model mice was evaluated at 30 min post-injection. SPECT/CT imaging studies of the three model mice were performed 30 min after injection of [123I]IIMU. RESULTS: Hepatic TYMP expression level was the highest in the SS mice and the lowest in the MASH mice at both mRNA and protein levels. The immunohistochemistry experiment showed a patchy distribution of TYMP only in the liver of MASH mice. In the biodistribution study, the hepatic accumulation of [125I]IIMU was the highest in the SS mice and the lowest in the MASH mice. The SPECT/CT imaging study showed similar results to the biodistribution experiment. CONCLUSION: Hepatic TYMP expression level may serve as a promising imaging biomarker for differential diagnosis of SS and MASH. SPECT imaging using [123I]IIMU potentially provides a novel noninvasive diagnostic method to differentiate MASH and SS. - Hypoxic culture enhances the antimicrobial activity of amnion-derived mesenchymal stem cells, thereby reducing bacterial load and promoting wound healing in diabetic mice

English, Scientific journal, BACKGROUND: Conditioned medium from amnion-derived mesenchymal stem cells (AMSCs) enhances wound healing, a process that is further improved under hypoxic culture conditions. Diabetic foot ulcers are difficult to treat and are frequently complicated by a high rate of bacterial infections, mainly Staphylococcus aureus, which can lead to limb amputation and death. Here, we topically applied conditioned medium from AMSCs cultured under hypoxic conditions to S. aureus-infected wounds in diabetic mice to investigate its effect on bacterial counts and wound healing. METHODS: We prepared conditioned medium by culturing AMSCs under 21 % or 1 % O2 and investigated its effects on S. aureus. We infected skin wounds of diabetic mice with S. aureus and treated these with hydrogels containing the conditioned medium to examine its effect on bacterial inhibition and wound healing. RESULTS: Conditioned medium from AMSCs cultured under 1 % O2 contained higher levels of the antimicrobial peptide LL-37. It significantly inhibited S. aureus growth in vitro, reduced bacterial counts in infected wounds, and facilitated wound closure in diabetic mice. CONCLUSIONS: Hydrogels containing conditioned medium from hypoxically cultured AMSCs inhibited the growth of S. aureus and promoted wound healing in a mouse model of diabetic wounds. - Positivity of high-sensitivity HBsAg test, not previous HBV infection, indicates poor prognosis in patients with non-HBV-related HCC.

English, Scientific journal, BACKGROUND AND AIMS: The prognostic impact of previous-HBV-infection (pHBV) in non-HBV-related hepatocellular carcinoma (non-HBV-related-HCC) and the prevalence, characteristics and significance of recently developed high-sensitivity HBs antigen positivity (hHBsAg+) in these patients remain unclear. We aimed to close these gaps. METHODS: We retrospectively screened patients with newly diagnosed non-HBV-related-HCC (standard HBsAg-test negative) at Hokkaido University. Patients with complete clinical information and preserved serum for hHBsAg+ were included. We evaluated the prevalence, characteristics and prognostic impact of pHBV and hHBsAg+ in non-HBV-related-HCC. RESULTS: A total of 401 non-HBV-related-HCC patients were included (288 with pHBV/113 without pHBV). In non-HBV-related-HCC, pHBV did not affect overall survival (OS). Among non-HBV-related-HCC patients with pHBV, 11.8% (34/288) were hHBsAg+ and had more advanced stages of HCC, higher AFP levels, higher vascular invasion rates, and significantly shorter OS than others (OS: 19.3 vs. 61.4 months, p = 0.012). Comparison of OS among non-HBV-related-HCC patients without pHBV (group 1), those with pHBV and without hHBsAg+ (group 2), and those with pHBV and hHBsAg+ (group 3) revealed significantly shorter OS in group 3 (19.3, 56.6 and 66.4 months in groups 1, 2 and 3, respectively; p = 0.036). Multivariate Cox regression indicated that compared with group 1, only group 3 was significantly and independently associated with shorter OS (HR: 2.044, p = 0.011). Subgroup analysis revealed that this association was particularly evident in non-HBV-related-HCC patients with non-B-non-C aetiology and advanced HCC. CONCLUSIONS: In non-HBV-related-HCC patients, hHBsAg+, not pHBV, is significantly and independently associated with poor prognosis. - Efficacy and Safety of Durvalumab/Tremelimumab in Unresectable Hepatocellular Carcinoma as Immune Checkpoint Inhibitor Rechallenge Following Atezolizumab/Bevacizumab Treatment.

English, Scientific journal, BACKGROUND: While guidelines recommend immune checkpoint inhibitor (ICI) rechallenge as second-line therapy for unresectable hepatocellular carcinoma (HCC), data supporting this remain limited, particularly regarding a standard regimen for first- and second-line treatments. Tremelimumab/durvalumab was recently approved but data on ICI rechallenge are lacking. OBJECTIVES: The purpose of this study was to evaluate the early efficacy and safety of tremelimumab/durvalumab for HCC as an ICI rechallenge following initial ICI therapy with atezolizumab/bevacizumab. PATIENTS AND METHODS: This multicenter retrospective study included patients with HCC who underwent treatment with tremelimumab/durvalumab, with relevant available clinical information. We evaluated the safety and efficacy of tremelimumab/durvalumab as ICI rechallenge following initial treatment with atezolizumab/bevacizumab. We analyzed the outcomes in patients who underwent tremelimumab/durvalumab as an ICI rechallenge and those who received tremelimumab/durvalumab as their initial ICI therapy RESULT: A total of 45 patients treated with tremelimumab/durvalumab were included, with 55.6% (25/45) undergoing ICI rechallenge. The objective-response and disease-control rates in patients who underwent ICI rechallenge were 14.3% (3/21) and 47.6% (10/21), respectively, similar to those in patients initially treated with tremelimumab/durvalumab. All patients (n = 3) who experienced the best response to progressive disease (PD) with initial atezolizumab/bevacizumab experienced PD during ICI rechallenge. The incidence rates of adverse events were similar between patient groups treated with tremelimumab/durvalumab as ICI rechallenge and initial ICI. Among patients experiencing immune-related adverse events (irAEs) with atezolizumab/bevacizumab, 75% (3/4) encountered similar irAEs during ICI rechallenge. CONCLUSION: Early safety and efficacy profiles of durvalumab/tremelimumab as ICI rechallenge are satisfactory. - Intracerebral transplantation of MRI-trackable autologous bone marrow stromal cells for patients with subacute ischemic stroke.

English, Scientific journal, BACKGROUND: Ischemic stroke is one of the leading causes of death and neurological disability worldwide, and stem cell therapy is highly expected to reverse the sequelae. This phase 1/2, first-in-human study evaluated the safety, feasibility, and monitoring of an intracerebral-transplanted magnetic resonance imaging (MRI)-trackable autologous bone marrow stromal cell (HUNS001-01) for patients with subacute ischemic stroke. METHODS: The study included adults with severe disability due to ischemic stroke. HUNS001-01 cultured with human platelet lysates and labeled with superparamagnetic iron oxide was stereotactically transplanted into the peri-infarct area 47-64 days after ischemic stroke onset (dose: 2 or 5 × 107 cells). Neurological and radiographic evaluations were performed throughout 1 year after cell transplantation. The trial was registered at UMIN Clinical Trial Registry (number UMIN000026130). FINDINGS: All seven patients who met the inclusion criteria successfully achieved cell expansion, underwent intracerebral transplantation, and completed 1 year of follow-up. No product-related adverse events were observed. The median National Institutes of Health Stroke Scale and modified Rankin scale scores before transplantation were 13 and 4, which showed improvements of 1-8 and 0-2, respectively. Cell tracking proved that the engrafted cells migrated toward the infarction border area 1-6 months after transplantation, and the quantitative susceptibility mapping revealed that cell signals at the migrated area constantly increased throughout the follow-up period up to 34% of that of the initial transplanted site. CONCLUSIONS: Intracerebral transplantation of HUNS001-01 was safe and well tolerated. Cell tracking shed light on the therapeutic mechanisms of intracerebral transplantation. FUNDING: This work was supported by the Japan Agency for Medical Research and Development (AMED; JP17bk0104045 and JP20bk0104011). - ブタ大腸内視鏡治療モデルを用いたESD後創部評価 新規生体吸収性素材とハイドロゲルを用いた内視鏡的絆創膏の効果

English, Scientific journal, BACKGROUND: Endoscopic submucosal dissection (ESD) has been the first-line treatment for early-stage esophageal cancer. However, it often causes postoperative stricture in cases requiring wide dissection. Basic fibroblast growth factor (bFGF) reportedly has anti-scarring effects during cutaneous wound healing. We hypothesized that suppressing myofibroblast activation will prevent stricture after esophageal ESD. METHODS: We resected a complete porcine esophagus circumference section by ESD. To investigate the preventive effect of bFGF on esophageal stricture formation after ESD, we endoscopically applied bFGF-soaked poly-glycolic acid (PGA) sheets onto the wound bed after ESD and fixed them by spraying fibrin glue (PGA + bFGF group), PGA sheets alone onto the wound bed and fixed them by spraying fibrin glue (PGA group), or nothing (control group). After removing the esophagus on day 22, we evaluated the mucosal constriction rate. RESULTS: Compared with those in the control group, esophageal stricture was significantly reduced in the PGA + bFGF group, and the areas stained with α-SMA and calponin-1 antibodies were significantly inhibited in the PGA + bFGF and PGA groups. The thickness of the fibrous layer in the PGA + bFGF group was uniform compared to that of the other groups. Thus, PGA + bFGF inhibited the development of unregulated fibroblasts in the acute phase, leading to uniform wound healing. CONCLUSIONS: Stenosis after esophageal ESD is related to fibrosis in the acute phase. Administration of PGA and bFGF suppresses myofibroblast activation in the acute phase, thereby preventing esophageal constriction in pigs. - 子宮がん患者のCINVに対する六君子湯の効果 プラセボ対照無作為化二重盲検比較試験

English, Scientific journal, Lenvatinib, used for unresectable hepatocellular carcinoma (HCC), causes appetite loss, but the underlying mechanisms, clinical impact, and predictive factors have been unclear. The endocrine factor FGF21 modulates appetite and is involved in cachexia. We evaluated the association between FGF21 level changes during lenvatinib treatment for unresectable HCC and appetite loss. Sixty-three eligible unresectable HCC patients who started lenvatinib treatment between 2018 and 2021 were included. We analyzed FGF21 levels at baseline; 1, 2, and 4 weeks after lenvatinib initiation, and before the onset of appetite loss. Grade ≥ 2 lenvatinib-induced appetite loss led to liver functional reserve deterioration at disease progression and a poor prognosis. Baseline characteristics and serum FGF21 levels were similar between patients with and without appetite loss. However, the serum FGF21 change rate increased significantly at 4 weeks post-lenvatinib initiation in patients with grade ≥ 2 appetite loss, as compared to those without appetite loss. Similar significant increases in the serum FGF21 level change rate were observed prior to grade ≥ 2 appetite loss onset. This suggests that changes in FGF21 levels can be used to predict patients with a greater risk of marked appetite loss and provides insights into the mechanisms underlying lenvatinib-induced appetite loss in patients with HCC. - Recent prevalence and characteristics of patients with hepatitis delta virus in Hokkaido, Japan.

English, Scientific journal, AIM: Although hepatitis delta virus (HDV) coinfection with hepatitis B virus (HBV) is a global health concern, the global prevalence of HDV infections remains unknown due to insufficient data in many countries. In Japan, HDV prevalence has not been updated for over 20 years. We aimed to investigate the recent prevalence of HDV infections in Japan. METHODS: We screened 1264 consecutive patients with HBV infection at Hokkaido University Hospital between 2006 and 2022. Patients' serums were preserved and subsequently tested for HDV antibody (immunoglobulin-G). Available clinical information was collected and analyzed. We compared the changes in liver fibrosis using the Fibrosis-4 (FIB-4) index between propensity-matched patients with and without the evidence of anti-HDV antibodies and corrected for baseline FIB-4 index, nucleoside/nucleotide analog treatment, alcohol intake, sex, HIV coinfection, liver cirrhosis, and age. RESULTS: After excluding patients without properly stored serums and those lacking appropriate clinical information, 601 patients with HBV were included. Of these, 1.7% of patients had detectable anti-HDV antibodies. Patients with anti-HDV antibody serum positivity had a significantly higher prevalence of liver cirrhosis, significantly lower prothrombin time, and a higher prevalence of HIV coinfection than those who demonstrated serum anti-HDV antibody negativity. A propensity-matched longitudinal analysis revealed that liver fibrosis (FIB-4 index) progressed more rapidly in patients with positive results for anti-HDV antibody tests. CONCLUSIONS: The recent prevalence of HDV infections in Japanese patients with HBV was 1.7% (10/601). These patients experienced rapid liver fibrosis progression, highlighting the importance of routine HDV testing. - Low Baseline CXCL9 Predicts Early Progressive Disease in Unresectable HCC with Atezolizumab Plus Bevacizumab Treatment.

English, Scientific journal, INTRODUCTION: Atezolizumab plus bevacizumab treatment is highly effective in patients with unresectable hepatocellular carcinoma (HCC). However, progressive disease (PD) occurs in approximately 20% of HCC patients treated with atezolizumab plus bevacizumab, resulting in a poor prognosis. Thus, the prediction and early detection of HCC is crucial. METHODS: Patients with unresectable HCC treated with atezolizumab plus bevacizumab and had baseline preserved serum (n = 68) were screened and classified according to their PD, 6 weeks after treatment initiation (early PD; n = 13). Of these, 4 patients each with and without early PD were selected for cytokine array and genetic analyses. The identified factors were validated in the validated cohort (n = 60) and evaluated in patients treated with lenvatinib. RESULTS: No significant differences were observed in the genetic alterations in circulating tumor DNA. Cytokine array data revealed that baseline MIG (CXCL9), ENA-78, and RANTES differed substantially between patients with and without early PD. Subsequent analysis in the validation cohort revealed that baseline CXCL9 was significantly lower in patients with early PD than that in patients without early PD, and the best cut-off value of serum CXCL9 to predict early PD was 333 pg/mL (sensitivity: 0.600, specificity: 0.923, AUC = 0.75). In patients with lower serum CXCL9 (<333 pg/mL), 35.3% (12/34) experienced early PD with atezolizumab plus bevacizumab, while progression-free survival (PFS) was significantly shorter relative to that in patients without (median PFS, 126 days vs. 227 days; HR: 2.41, 95% CI: 1.22-4.80, p = 0.0084). While patients with objective response to lenvatinib had significantly lower CXCL9 levels compared with those of patients without. CONCLUSION: Baseline low serum CXCL9 (<333 pg/mL) levels may predict early PD in patients with unresectable HCC treated with atezolizumab plus bevacizumab. - ポリグリコール酸シートと塩基性線維芽細胞増殖因子を用いたESD後の食道狭窄に対する新規予防法の開発

English, Scientific journal, AIM: Hepatitis C virus (HCV) infection has been reported to cause liver steatosis. Thus, eradicating HCV with direct-acting antivirals (DAAs) is expected to reduce liver steatosis. We aimed to clarify long-term changes in the prevalence of fatty liver and hyper-low-density lipoprotein (LDL) cholesterolemia and their associations in patients who achieve successful HCV eradication using DAAs. METHODS: This retrospective study included patients with HCV who achieved sustained virologic response after interferon-free DAA and analyzed the changes in the prevalence of fatty liver diagnosed with controlled attenuation parameter (CAP), hyper-LDL cholesterolemia, and their relationships at baseline (n = 100) and 24 weeks (SVR24, n = 100), 96 weeks (SVR96, n = 100), and 144 weeks (SVR144, n = 90) after DAA. RESULTS: In 100 participants, the prevalence of fatty liver (19% vs. 32%, p = 0.0349) and hyper-LDL cholesterolemia (6% vs. 15%, p = 0.0379) significantly increased without changes in body weight at SVR96. Median total cholesterol, low-density lipoprotein cholesterol (LDL-C), and small-dense-LDL (sdLDL) levels and CAP values were significantly greater at SVR24, SVR96, and SVR144 than at baseline. Baseline CAP values and changes in CAP values were significantly negatively correlated at every observation point: r = -0.5305, p < 0.0001 at SVR24; r = -0.3617, p = 0.0005 at SVR96; and r = -0.4735, p < 0.0001 at SVR144. A similar relationship was observed in cholesterol levels. Unlike at baseline, CAP values were significantly positively correlated with LDL-C and sdLDL-C levels at all observation points after DAAs. CONCLUSIONS: Direct-acting antivirals may cause an increased prevalence of fatty liver accompanying hyper-LDL cholesterolemia without increased body weight. As post-SVR liver steatosis could cause HCC, careful follow-up may be required. - Changes in Serum Growth Factors during Resistance to Atezolizumab Plus Bevacizumab Treatment in Patients with Unresectable Hepatocellular Carcinoma.

English, Scientific journal, The possible mechanisms of resistance to atezolizumab/bevacizumab for unresectable HCC, and the subsequent response to these therapies, remain underexplored. The sequential changes in serum growth factors, including VEGF-A, VEGF-C, VEGF-D, ANG-2, FGF-19, HGF, and EGF during atezolizumab/bevacizumab for unresectable HCC were evaluated in 46 patients. Patients who experienced PD after CR, PR, or SD to atezolizumab/bevacizumab were evaluated. A total of 4, 9, 19, and 14 patients showed CR, PR, SD, and PD, respectively. Of 32 patients with disease control, 28 experienced PD after CR, PR, or SD with atezolizumab/bevacizumab. Baseline growth factor levels were similar between patients with or without disease control and those with or without an objective response. Growth factor changes between the baseline and the best overall response points (BOR) for patients with disease control showed that FGF-19 significantly increased and ANG2 significantly decreased at the BOR. Growth factor changes between the BOR and the PD point in 28 patients who experienced PD after disease control showed that VEGF-D and ANG2 significantly increased at the PD point compared with that at the BOR. Summarily, increased serum VEGF-D and ANG-2 levels might contribute to developing resistance to atezolizumab/bevacizumab for unresectable HCC and might be target molecules in subsequent salvage therapies. - Serum Angiopoietin-2 Predicts the Occurrence and Recurrence of Hepatocellular Carcinoma after Direct-Acting Antiviral Therapy for Hepatitis C.

English, Scientific journal, Progressive liver fibrosis after anti-HCV treatment is a risk factor for HCC. Angiopoietin-2 (Ang2) is associated with non-regression of liver fibrosis after direct-acting antiviral (DAA). This study evaluated the predictive value of serum Ang2 levels for HCC occurrence or recurrence after DAA administration. In this retrospective study, 310 HCV-infected patients treated with DAAs in 2014-2020 were screened and evaluated for HCC occurrence or recurrence every three-six months. Multivariate Cox regression analysis revealed that age ≥ 75 years (HR: 2.92, 95% CI: 1.34-6.33; p = 0.007) and baseline Ang2 level ≥ 464 pg/mL (HR: 2.75, 95% CI: 1.18-6.37; p = 0.019) were significantly associated with HCC occurrence after DAA therapy. A high or low risk of HCC after DAA therapy could be distinguished by the combination of age and baseline Ang2 level. The cumulative incidences of de-novo HCC at two and four years were 0.8% and 3.8% in the low-risk group and 22.6% and 27.1% in the high-risk group, respectively. Baseline Ang2 level ≥ 402 pg/mL was significantly associated with HCC recurrence in patients who achieved sustained virological response with DAAs (HR: 3.68). In conclusion, serum Ang2 levels can predict HCC occurrence and recurrence after successful HCV eradication by DAAs. - Prophylactic tenofovir alafenamide for hepatitis B virus reactivation and reactivation-related hepatitis.

English, Scientific journal, BACKGROUND: No prospective study on the efficacy of tenofovir alafenamide (TAF), a novel tenofovir prodrug, in preventing HBV reactivation has yet been reported. METHODS: This multicenter prospective study enrolled HBV-carriers who received TAF to prevent HBV reactivation before antitumor or immunosuppressive therapy, and patients with resolved HBV infection who experienced HBV-reactivation and received TAF to prevent HBV reactivation-related hepatitis. The efficacy of prophylactic TAF in preventing HBV reactivation and HBV reactivation-related hepatitis was evaluated at 6 and 12 months after initiating TAF. RESULTS: Overall, 110 patients were administered TAF to prevent HBV reactivation or HBV reactivation-related hepatitis. Three patients died owing to primary disease, whereas one patient was transferred to another hospital within 6 months after initiating TAF. Seven patients died due to primary disease, and five patients were transferred to another hospital within 12 months after initiating TAF. Therefore, 106 and 94 (77 patients with HBV infection, 17 with previous-HBV infection) patients were evaluated at 6 and 12 months after initiating TAF, respectively. No patient experienced HBV reactivation, HBV reactivation-related hepatitis, or treatment discontinuation due to HBV reactivation or adverse events of TAF after 6 and 12 months. CONCLUSION: TAF could effectively prevent HBV reactivation and HBV reactivation-related hepatitis. This article is protected by copyright.

English, Scientific journal, INTRODUCTION: We aimed to assess the prognostic implications of muscle atrophy and high subcutaneous adipose tissue (SAT) radiodensity in patients with hepatocellular carcinoma (HCC). METHODS: In this retrospective study, muscle atrophy was assessed using the psoas muscle index (PMI) obtained from computed tomography. SAT radiodensity was evaluated based on radiodensity measurements. Survival and multivariate analyses were performed to identify factors associated with prognosis. The impact of muscle atrophy and high SAT radiodensity on prognosis was determined through survival analysis. RESULTS: A total of 201 patients (median age: 71 years; 76.6% male) with HCC were included. Liver cirrhosis was observed in 72.6% of patients, and the predominant Child-Pugh grade was A (77.1%). A total of 33.3% of patients exhibited muscle atrophy based on PMI values, whereas 12.9% had high SAT radiodensity. Kaplan-Meier survival analysis demonstrated that patients with muscle atrophy had significantly poorer prognosis than those without muscle atrophy. Patients with high SAT radiodensity had a significantly worse prognosis than those without it. Muscle atrophy, high SAT radiodensity, the Barcelona Clinic Liver Cancer class B, C, or D, and Child-Pugh score ≥ 6 were significantly associated with overall survival. Further classification of patients into four groups based on the presence or absence of muscle atrophy and high SAT radiodensity revealed that patients with both muscle atrophy and high SAT radiodensity had the poorest prognosis. CONCLUSION: Muscle atrophy and high SAT radiodensity are significantly associated with poor prognosis in patients with HCC. Identifying this high-risk subgroup may facilitate the implementation of targeted interventions, including nutritional therapy and exercise, to potentially improve clinical outcomes. - Serum IL-1β predicts de novo hepatitis B virus reactivation during direct-acting antiviral therapy for hepatitis C, not during anti-cancer/immunosuppressive therapy

Scientific journal, Abstract
De novo hepatitis B virus (HBV) reactivation occurs during direct-acting antiviral (DAA) treatment in hepatitis C virus (HCV)-infected patients with resolved HBV infection. We evaluated the predictive factors, mechanical insight, and differences of cytokine levels during anti-cancer/immunosuppressive and DAA. Eleven, 35, and 19 HCV-infected patients with previous HBV infection with HBV reactivation during DAA treatment, previous HBV infection without HBV reactivation during DAA treatment, and without HBV infection resolution receiving DAA treatment, respectively, were enrolled. Clinical data and baseline cytokine levels were analyzed. Low baseline serum interleukin (IL)-1β levels predicted de novo HBV reactivation during DAA treatment (odds ratio: 47.6, 95% confidence interval: 6.94–333.3). HCV-infected patients with the IL-1β gene single nucleotide polymorphism rs16944 AA allele had significantly higher IL-1β levels; no HCV-infected patient with the IL-1β AA allele experienced HBV reactivation during DAA treatment. Compared to HCV-infected patients with HBV infection resolution, non-HCV infected patients with or without HBV reactivation during anti-cancer/immunosuppressive therapy or bone marrow transplantation had remarkably lower baseline IL-1β levels. Low IL-1β levels were not associated with HBV reactivation. IL-1β levels before DAA for HCV-infected patients with resolved HBV infection could predict HBV reactivation during DAA treatment. - Efficacy and Effect on Liver Functional Reserve of Atezolizumab and Bevacizumab for Unresectable Hepatocellular Carcinoma in Patients Who Do Not Meet Eligibility Criteria of IMbrave150

Scientific journal, The IMbrave150 trial demonstrated the high efficacy and safety of atezolizumab and bevacizumab for unresectable hepatocellular carcinoma (HCC). In this multicenter study, the efficacy of this combination and its effect on liver functional reserve were evaluated in patients not meeting the eligibility criteria of IMbrave150. Of 115 patients with unresectable HCC treated with atezolizumab and bevacizumab between October 2020 and January 2022, 72 did not meet the eligibility criteria of IMbrave150, most frequently due to a history of systemic therapy (60/72), platelet counts < 75 × 109/L (7/72), Child-Pugh B (9/72), and 2+ proteinuria (8/72). Atezolizumab and bevacizumab therapy was equally effective for patients who did or did not meet the eligibility criteria (PFS, 6.5 vs. 6.9 months, p = 0.765), consistent with subgroup analyses of histories of systemic therapy, platelet counts, Child-Pugh, and proteinuria. Baseline ALBI scores were worse in patients who did not meet the criteria than in those who did and significantly worsened after treatment initiation in patients not meeting the criteria (baseline vs. 12 weeks; 2.35 ± 0.43 vs. −2.18 ± 0.54; p = 0.007). Accordingly, atezolizumab plus bevacizumab was effective for patients not meeting the eligibility criteria of IMbrave150, although careful monitoring for changes in liver functional reserve is needed. - Small-molecule inhibitor cocktail promotes the proliferation of pre-existing liver progenitor cells.

English, Scientific journal, A recent study showed that a cocktail of three small molecules, Y-27632, A83-01, and CHIR99021 (YAC), converts mature hepatocytes (MHs) into proliferative bipotent cells that can be induced into MHs and cholangiocytes in rats. However, when we reproduced these experiments, it was found that bipotent cells may be derived from resident liver progenitor cells (LPCs), whose proliferative activity was promoted by YAC. A simple and efficient sorting scheme was also developed in this study to harvest high-purity and high-yield LPCs. The inducible bipotency of purified LPCs was verified; in addition, they were found to spontaneously differentiate into hepatocytes and cholangiocytes due to changes in proliferative status even without induction. Moreover, during the differentiation process, some hepatocytes spontaneously reconverted to LPCs under certain conditions, such as the release of contact inhibition. These findings may improve our understanding of LPCs and provide a cell source for regenerative medicine. - The potential of soluble CD14 in discriminating nonalcoholic steatohepatitis from nonalcoholic fatty liver disease.

English, Scientific journal, BACKGROUND AND AIMS: Although various noninvasive markers and prediction formulas for nonalcoholic steatohepatitis (NASH) have been reported, they are of value only in the diagnosis of the advanced fibrosis stage of NASH. In this study, we evaluated soluble CD14 (sCD14) as a diagnostic marker for discriminating NASH from nonalcoholic fatty liver disease (NAFLD) using an animal model and clinical specimens. METHODS: Serum sCD14 levels were measured in samples derived from mice with diet-induced NASH and patients using an enzyme-linked immunosorbent assay. Our cohort enrolled 126 patients with liver needle biopsy-proven NAFLD. RESULTS: The intestinal defense mechanism in NASH model mice was altered as a consequence of the unique gut environment. Elevated serum levels of sCD14 were observed in mice with diet-induced NASH, and the condition of the liver was exacerbated as a result of exposure to gut-derived endotoxin. We confirmed that the serum sCD14 levels in NAFL patients significantly differed from those in NASH patients. The area under the curve for distinguishing between NAFL and NASH was 0.891. Moreover, we found that serum sCD14 levels were weakly correlated with the inflammation grade based on the NAFLD activity score (NAS), the grade of fibrosis according to the Brunt fibrosis classification, and a positive correlation with the grade of ballooning based on NAS in patients with NAFLD. CONCLUSION: sCD14 could be a useful pathophysiological marker and diagnostic adjunct distinguishing NASH from NAFLD. The use of sCD14 may allow the screening and identification of high-risk groups for NASH development and support early therapeutic interventions. - Overestimated Renal Function in Patients with Liver Cirrhosis Predicts Poor Prognosis.

English, Scientific journal, AIM: A high prevalence of overestimated renal function in patients with liver cirrhosis (LC) has been reported; nonetheless, its impact on prognosis remains unclear. We aimed to evaluate the impact of overestimated renal function on prognosis in patients with LC. METHODS: An overestimated renal function was defined as a >20% increase in the creatinine-based estimated glomerular filtration rate (eGFR), compared with cystatin C-based eGFR. LC patients with conserved serum, who were evaluated for muscle atrophy and had proper clinical information were included, and their prognostic factors were analyzed. RESULTS: A total of 215 consecutive patients with LC were included. The prevalence of overestimated renal function was 29.8% (64/215). Kaplan-Meier survival analysis revealed that patients with overestimated renal function had a poorer prognosis than those without overestimated renal function (hazard ratio [HR]: 2.217 95% confidence interval [CI]: 1.290-3.810; P=0.001). Subgroup analysis showed that overestimated renal function was a significant prognostic factor, irrespective of sex and the presence of hepatocellular carcinoma (HCC). Multivariate Cox regression analyses revealed that overestimated renal function was a significant and independent factor predictive of poor prognosis in the entire cohort (HR: 2.050; 95% CI: 1.041-4.037; P=0.038) and in subgroups classified by Child-Pugh class A (HR: 2.131; 95% CI: 1.019-4.458; P=0.044), Model for End-Stage Liver Disease score <9 (HR: 2.303; 95% CI: 1.038-5.109; P=0.04), and presence of HCC (HR: 2.290; 95% CI: 1.128-4.651; P=0.022). CONCLUSION: Overestimated renal function is a significant and independent prognostic factor in patients with LC. This article is protected by copyright.

English, Scientific journal, Serum growth factor changes and their effect on prognosis during lenvatinib for unresectable hepatocellular carcinoma (HCC) remain underexplored. The sequential changes in serum growth factors during lenvatinib for unresectable HCC were evaluated in 58 patients using complete clinical data, and preserved serum was used to investigate changes in FGF-19, ANG-2, HGF, VEGF, and EGF. Patients with a complete response (CR), partial response (PR), and stable disease (SD) were evaluated for growth factor changes between the best response and progressive disease (PD) points, classified based on these changes, and evaluated by post progression survival (PPS). A total of 8, 24, 18, and 8 patients showed CR, PR, SD, and PD, respectively. Multivariate analysis revealed that age, relative dose intensity, and baseline ANG-2 were significantly associated with treatment response. Growth factor changes between the best response and PD points revealed that patients could be classified into four groups based on the EGF, ANG-2, and HGF changes. Although patient characteristics at baseline and PD, their response to lenvatinib, and PFS were similar among those groups, patients with an increase in all growth factors had significantly shorter PPS (median PPS was 553, 323, and 316 versus 173 days in groups 1-4 p = 0.032). We revealed that the evaluation of the changes in growth factors during lenvatinib could predict PPS. - Intravenous transplantation of amnion-derived mesenchymal stem cells promotes functional recovery and alleviates intestinal dysfunction after spinal cord injury.

English, Scientific journal, Spinal cord injury (SCI) is often accompanied by gastrointestinal dysfunction due to the disconnection of the spinal autonomic nervous system. Gastrointestinal dysfunction reportedly upregulates intestinal permeability, leading to bacterial translocation of the gut microbiome to the systemic circulation, which further activates systemic inflammation, exacerbating neuronal damage. Mesenchymal stem cells (MSC) reportedly ameliorate SCI. Here, we aimed to investigate their effect on the associated gastrointestinal dysfunction. Human amnion-derived MSC (AMSCs) were intravenously transplanted one day after a rat model of midthoracic SCI. Biodistribution of transplanted cells, behavioral assessment, and histological evaluations of the spinal cord and intestine were conducted to elucidate the therapeutic effect of AMSCs. Bacterial translocation of the gut microbiome was examined by in situ hybridization and bacterial culture of the liver. Systemic inflammations were examined by blood cytokines, infiltrating immune cells in the spinal cord, and the size of the peripheral immune tissue. AMSCs released various neurotrophic factors and were mainly distributed in the liver and lung after transplantation. AMSC-transplanted animals showed smaller spinal damage and better neurological recovery with preserved neuronal tract. AMSCs transplantation ameliorated intestinal dysfunction both morphologically and functionally, which prevented translocation of the gut microbiome to the systemic circulation. Systemic inflammations were decreased in animals receiving AMSCs in the chronic phase. Intravenous AMSC administration during the acute phase of SCI rescues both spinal damage and intestinal dysfunction. Reducing bacterial translocation may contribute to decreasing systemic inflammation. - Autograft of Demineralized Dentin Matrix Prepared Immediately after Extraction for Horizontal Bone Augmentation of the Anterior Atrophic Maxilla: A First Case of Non-Vital Tooth-Derived Dentin

Scientific journal,Abstract We aimed to evaluate factors associated with changes in skeletal muscle mass in hepatitis C virus (HCV)-infected patients after treatment with direct-acting antivirals (DAAs). Consecutive HCV-infected patients after treatment with DAA were recruited into the study. Patients who achieved sustained virological response (SVR); and had complete clinical information, preserved serum samples at baseline and SVR48, and skeletal muscle mass evaluations based on the psoas muscle mass index (PMI) on computed tomography at baseline and ≥ 12 months were included. Altogether, 70.7% of patients (41/58) showed increased PMI after DAA therapy, and mean relative PMI was significantly higher after DAA therapy than at baseline. There were no significant associations between baseline clinical factors routinely examined in clinical practice and increased PMI. Among factors reported to be associated with skeletal muscle loss in patients with chronic liver disease, serum zinc levels and total and free carnitine levels increased significantly after DAA therapy and only changes in serum free carnitine levels were significantly associated with an increased PMI (r = 0305,P = 0.020). In conclusion, increased skeletal muscle mass after successful HCV eradication by DAAs was significantly associated with increased serum-free carnitine levels.l -carnitine supplementation may be beneficial in patients with low skeletal muscle mass after DAA. - Early response and safety of atezolizumab plus bevacizumab for unresectable hepatocellular carcinoma in patients who do not meet IMbrave150 eligibility criteria.

English, Scientific journal, AIM: A clinical trial (IMbrave150) indicated the efficacy and safety of atezolizumab plus bevacizumab for patients with unresectable hepatocellular carcinoma (HCC). In this study, we evaluated this therapeutic combination in a real-world setting, with a focus on patients who did not meet the IMbrave150 eligibility criteria. METHODS: In this multicenter study, patients with unresectable HCC treated with atezolizumab plus bevacizumab between October 2020 and May 2021 were screened. In patients who did not meet IMbrave150 eligibility criteria, treatment responses and safety at 6 and 12 weeks were evaluated. RESULTS: Atezolizumab plus bevacizumab was initiated in 64 patients, including 46 patients (71.9%) who did not meet IMbrave150 eligibility criteria. Most of these patients had a history of systemic therapy (44/46). The objective response rate and disease control rate observed using Response Evaluation Criteria in Solid Tumors 1.1 were 5.2% and 82.8% at 6 weeks and 10.0% and 84.0% at 12 weeks, respectively; these rates were similar between patients who met and did not meet the IMbrave150 criteria. Ten patients experienced progressive disease (PD) at 6 weeks. Portal vein tumor thrombosis was significantly associated with PD (p = 0.039); none of the 15 patients with hepatitis B virus-related HCC experienced PD (p = 0.050). The most common adverse events of grade 3 or higher were aspartate aminotransferase elevation (n = 8, 13.8%) and the safety profile was similar between patients who met and did not meet the IMbrave150 criteria. CONCLUSION: Most patients treated with atezolizumab plus bevacizumab did not meet the IMbrave150 criteria; however, the combination therapy showed good safety and efficacy at the early treatment phase. - The TLR4–TRIF–type 1 IFN–IFN-γ pathway is crucial for gastric MALT lymphoma formation after Helicobacter suis infection

English, Scientific journal, Helicobacter suis, a zoonotic infection-related bacterium, can induce gastric mucosa-associated lymphoid tissue (MALT) lymphoma in humans and animals. Recently, we reported that the formation of gastric MALT lymphoma after H. suis infection is induced by interferon (IFN)-γ activation. Here, we revealed that activation of the Toll-like receptor (TLR) 4-Toll/IL-1 receptor domain-containing adapter-inducing interferon-β (TRIF) pathway after H. suis infection is associated with the production of type 1 IFNs (IFN-α, IFN-β) by gastric epithelial cells. Additionally, these type 1 IFNs interact with type 1 IFN receptors on gastric B cells, facilitating the secretion of IFN-γ and the activation of which is enhanced by positive feedback regulation in B cells. These results suggest that the TLR4-TRIF-type 1 IFN-IFN-γ pathway is crucial in the development of gastric MALT lymphoma after H. suis infection and may, therefore, represent a therapeutic target for the prevention of this condition. - Characteristics and Lenvatinib Treatment Response of Unresectable Hepatocellular Carcinoma with Iso-High Intensity in the Hepatobiliary Phase of EOB-MRI

English, Scientific journal, In hepatocellular carcinoma (HCC), CTNNB-1 mutations, which cause resistance to immune checkpoint inhibitors, are associated with HCC with iso-high intensity in the hepatobiliary phase of gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) in resectable HCC; however, analyses on unresectable HCC are lacking. This study analyzed the prevalence, characteristics, response to lenvatinib, and CTNNB-1 mutation frequency in unresectable HCC with iso-high intensity in the hepatobiliary phase of EOB-MRI. In 52 patients with unresectable HCC treated with lenvatinib, the prevalence of iso-high intensity in the hepatobiliary phase of EOB-MRI was 13%. All patients had multiple HCCs, and 3 patients had multiple HCCs with iso-high intensity in the hepatobiliary phase of EOB-MRI. Lenvatinib response to progression-free survival and overall survival were similar between patients with or without iso-high intensity in the hepatobiliary phase of EOB-MRI. Seven patients (three and four patients who had unresectable HCC with or without iso-high intensity in the hepatobiliary phase of EOB-MRI, respectively) underwent genetic analyses. Among these, two (67%, 2/3) who had HCC with iso-high intensity in the hepatobiliary phase of EOB-MRI carried a CTNNB-1 mutation, while all four patients who had HCC without iso-high intensity in the hepatobiliary phase of EOB-MRI did not carry the CTNNB-1 mutation. This study's findings have clinical implications for the detection and treatment of HCC with iso-high intensity in the hepatobiliary phase of EOB-MRI. - Frequency and Characteristics of Overestimated Renal Function in Japanese Patients with Chronic Liver Disease and Its Relation to Sarcopenia

English, Scientific journal, Renal dysfunction and sarcopenia are important prognostic factors in patients with chronic liver disease (CLD). Muscle atrophy can cause the overestimation of renal function based on serum creatinine. However, the frequency of overestimated renal function in Japanese patients with CLD and its relationship with sarcopenia are unclear. In present study, we evaluated the frequency of overestimated renal function, defined as a >20% higher eGFR using creatinine than using cystatin C, in 307 patients with CLD as well as its relationship with indicators of sarcopenia. In total, 24.8% of patients had overestimated renal function. In a multivariate regression analysis, liver cirrhosis (p = 0.004) and psoas muscle mass index (p = 0.049) were significantly associated with overestimated renal function. Loss of skeletal muscle mass was significantly more frequent in both male and female patients with overestimated renal function than without. In males, the loss of muscle strength and rate of sarcopenia, defined as loss of muscle mass and strength, were significantly higher in patients with than without overestimated renal function. The high frequency of overestimated renal function in Japanese patients suggests that indicators of renal function should be carefully considered; furthermore, monitoring and interventions for both renal function and sarcopenia are needed in patients with CLD. - FGFR2 maintains cancer cell differentiation via AKT signaling in esophageal squamous cell carcinoma.

English, Scientific journal, Fibroblast growth factors (FGFs) and their receptors (FGFRs) are important for signaling to maintain cancer stem-like cells (CSCs) in esophageal squamous cell carcinoma (ESCC). However, which FGF receptor, 1, 2, 3, 4, and L1, is essential or whether FGFRs have distinct different roles in ESCC-CSCs is still in question. This study shows that FGFR2, particularly the IIIb isoform, is highly expressed in non-CSCs. Non-CSCs have an epithelial phenotype, and such cells are more differentiated in ESCC. Further, FGFR2 induces keratinocyte differentiation through AKT but not MAPK signaling and diminishes CSC populations. Conversely, knockdown of FGFR2 induces epithelial-mesenchymal transition (EMT) and enriches CSC populations in ESCC. Finally, data analysis using The Cancer Genome Atlas (TCGA) dataset shows that expression of FGFR2 significantly correlated with cancer cell differentiation in clinical ESCC samples. The present study shows that each FGFR has a distinct role and FGFR2-AKT signaling is a key driver of keratinocyte differentiation in ESCC. Activation of FGFR2-AKT signaling could be a future therapeutic option targeting CSC in ESCC. - Topical Application of Conditioned Medium from Hypoxically Cultured Amnion-Derived Mesenchymal Stem Cells Promotes Wound Healing in Diabetic Mice.

English, Scientific journal, BACKGROUND: Mesenchymal stem cells or their conditioned medium improve chronic wound healing, and their effect is enhanced by hypoxia. Diabetic foot ulcers are chronic wounds characterized by abnormal and delayed healing, which frequently require amputation. The authors evaluated the effect of topical application of conditioned medium from hypoxically cultured amnion-derived mesenchymal stem cells on wound healing in diabetic mice. METHODS: Amnion-derived mesenchymal stem cells were cultured under 21% oxygen to prepare normoxic conditioned medium and under 1% oxygen to prepare hypoxic conditioned medium. Hydrogels containing standard medium, normoxic conditioned medium, or hypoxic conditioned medium were topically applied to excisional wounds of mice with streptozotocin-induced diabetes. Ulcer tissues were harvested on day 9; immunohistochemical and quantitative polymerase chain reaction analyses were performed to analyze angiogenesis, inflammatory cell infiltration, and expression levels of inflammation-related genes. RESULTS: Hypoxic conditioned medium significantly enhanced wound closure, increased capillary density and epithelization, and reduced macrophage infiltration. It also tended to reduce the infiltration of neutrophils and enhance the infiltration of regulatory T cells; it showed a tendency to downregulate the expression of the inflammation-related genes interleukin-1β, interleukin-6, chemokine ligand 1, and chemokine ligand 2. Normoxic conditioned medium exhibited similar effects, although they were of lesser magnitude than those of hypoxic conditioned medium. CONCLUSIONS: Hydrogels containing hypoxically cultured, amnion-derived mesenchymal stem cell conditioned medium accelerated wound healing in diabetic mice by enhancing angiogenesis, accelerating epithelization, and suppressing inflammation. Therefore, topical application of amnion mesenchymal stem cell-derived hypoxic conditioned medium could be a novel treatment for diabetic foot ulcers. - A protocol for efficacy of rikkunshito on chemotherapy-induced nausea and vomiting in patients with uterine corpus or cervical cancer treated with cisplatin-based regimen -placebo-controlled, double-blind, randomized confirmatory study (efficacy of rikkunshito on chemotherapy-induced nausea and vomiting)

English, Scientific journal, In hepatocellular carcinoma (HCC), a subset of cells defined by high CD44 and CD133 expression has been reported to possess cancer stem-like cell (CSC) characteristics and to be associated with a poor prognosis. Since the approval of the multikinase inhibitor, lenvatinib, for patients with unresectable HCC, two such inhibitors (sorafenib and lenvatinib) have been employed as first-line systemic chemotherapeutics for these patients. Based on differences in the kinase-affinity profiles between these two drugs, evidence has suggested that both exert different effects on HCC, although these differences are not fully characterized. In this study, using in vitro and a preclinical in vivo xenograft mouse model, we showed that lenvatinib alone (not sorafenib or the cytotoxic agent, 5-fluorouracil) diminished CD44High/CD133High CSCs in HCC. Furthermore, western blotting and reverse transcriptase-polymerase chain reaction analysis revealed that the expression of fibroblast growth factor receptor (FGFR)-1-4 differed between CD44High/CD133High CSCs and control cells. Analysis of the effects of selective FGFR inhibitors and FGFR small interfering RNAs on CSCs in HCC revealed that lenvatinib diminished CSCs in HCC by inhibiting FGFR1-3 signaling, however, FGFR4 signaling was not impacted. Finally, we showed that FGF2 and FGF19 were involved in maintaining CD44High/CD133High CSCs in HCC, potentially, via FGFR1-3. The findings provide novel mechanistic insights into the effects of lenvatinib on CSCs in HCC and provide clues for developing effective targeted therapies against CSCs in HCC. - Tenofovir-disoproxil-fumarate modulates lipid metabolism via hepatic CD36/PPAR-alpha activation in hepatitis B virus infection.

English, Scientific journal, BACKGROUND: Entecavir and tenofovir-disoproxil-fumarate are first-line nucleos(t)ide analogs (NA) for treatment of hepatitis B virus (HBV) infections; however, their long-term administration can impact extrahepatic organs. Herein, we sought to examine the effect of NA on lipid metabolism while also characterizing the associated mechanism. METHODS: A retrospective study was performed on HBV patients administered entecavir or tenofovir-disoproxil-fumarate. Patient clinical information, as well as their preserved serum samples obtained at baseline and 6-12 months after treatment initiation, were analyzed. A 1:1 propensity score matching was applied to the assignment of tenofovir-disoproxil-fumarate or entecavir treatment. Changes in serum cholesterol, including oxidized-LDL, were analyzed. Subsequently, in vitro analysis elucidated the mechanism associated with the effect of NAs on lipid metabolism. RESULTS: Administration of tenofovir-disoproxil-fumarate, not entecavir, to chronic HBV patients, decreased serum cholesterol levels, including non-HDL and oxidized-LDL, which are strongly associated with arteriosclerosis. In vitro analysis revealed that tenofovir-disoproxil-fumarate reduced supernatant cholesterol, and upregulated the scavenger receptor, CD36, in hepatocytes. Meanwhile, silencing of hepatic CD36 increased supernatant cholesterol and negated the cholesterol-reducing effect of tenofovir-disoproxil-fumarate in HepG2-cells. Reporter, microarray, and RT-PCR analyses further revealed that tenofovir-disoproxil-fumarate treatment activates PPAR-α-mediated signaling, and upregulates PPAR-α target genes, including CPT1 and CD36. Alternatively, silencing of PPAR-α reversed the effects of tenofovir-disoproxil-fumarate on CD36. CONCLUSIONS: Tenofovir-disoproxil-fumarate modulates lipid metabolism by upregulating hepatic CD36 via PPAR-α activation. Since dyslipidemia could be associated with arteriosclerosis and hepatocarcinogenesis, these discoveries provide novel insights into anti-HBV therapies, as well as the associated extrahepatic effects of NA. - Prevalence, clinical course, and predictive factors of immune checkpoint inhibitor monotherapy-associated hepatitis in Japan.

English, Scientific journal, BACKGROUND AND AIM: Immune checkpoint inhibitors (ICI) have revolutionized anti-malignancy therapy and thus have been increasingly used. Although ICI may cause immune-related adverse events (irAE) in various organs, including the liver, the prevalence and predictive factors of irAE have not been clarified. METHODS: In this retrospective study, consecutive patients who had malignancies and were treated with ICI without other chemotherapeutic agents at Hokkaido University Hospital between 2014 and 2019 were screened. Patients were excluded if they were < 20 years old and had insufficient clinical data. RESULTS: Of the 233 patients screened, 202 patients met the inclusion criteria and were included in the analysis. The patients were aged 25-92 years, and 60.9% were male. The patients received nivolumab (n = 137), pembrolizumab (n = 45), ipilimumab (n = 17), atezolizumab (n = 2), and avelumab (n = 1). The prevalence of any grade and grade ≥ 3 irAE hepatitis was 8.4% (17/202) and 4.0% (8/202), respectively. irAE hepatitis occurred at a median duration of 42 days in any grade and 36 days in grade ≥ 3 after ICI initiation. The clinical course of grade ≥ 3 irAE hepatitis was generally favorable; however, 50% required corticosteroid treatment and two patients required additional mycophenolate mofetil. Female sex and history of ICI treatment were significantly associated with the incidence of grade ≥ 3 irAE hepatitis. CONCLUSIONS: Grade ≥ 3 irAE hepatitis was observed in 4.0% of the patients who were treated with ICI. Female sex and history of ICI treatment were significantly associated with the incidence of grade ≥ 3 irAE hepatitis. - 生体ブタ全周性食道ESD施行後のバルーン拡張時の病理組織学的検討

Japanese, CD133 is a cellular surface protein, which has been reported to be a cancer stem cell marker, and thus is considered a potential target for cancer treatment. Metformin is also known to reduce the risk of cancer development and cancer stem cells (CSCs), including the expression of CD133. However, the mechanism underlying the reduction of the expression of CD133 by metformin is not yet understood. This study shows that metformin suppressed CD133 expression mainly by affecting the CD133 P1 promoter via AMPK signaling. AMPK inhibition rescued the reduction of CD133 by metformin. Further experiments demonstrated that CEBPβ was upregulated by metformin and that two isoforms of CEBPβ reciprocally regulated the expression of CD133. Specifically, the liver-enriched activator protein (LAP) isoform increased the expression of CD133 by directly binding to the P1 promoter region, whereas the liver-enriched inhibitory protein (LIP) isoform suppressed the expression of CD133. Consistent with these findings, a 3D culture assay and drug sensitivity assay demonstrated that LAP-overexpressing cells formed large spheroids and were more resistant to 5-FU treatment, whereas LIP-overexpressing cells were more sensitive to 5-FU and showed combined effects with metformin. Our results indicated that metformin-AMPK-CEBPb signaling plays a crucial role in regulating the gene expression of CD133. Additionally, regulating the ratio of LAP/LIP may be a novel strategy for targeting CSCs for the treatment of cancer. - Evaluation of amnion-derived mesenchymal stem cells for treatment-resistant moderate Crohn's disease: study protocol for a phase I/II, dual-centre, open-label, uncontrolled, dose-response trial

Japanese, Background: Based on a case who developed anaphylaxis after mouse bite which occurred at Hokkaido University, we studied on allergic sensitization prevalence for laboratory animals among students and researchers who are exposed to laboratory rodents and rabbit, for the purpose of allergy prevention, particularly anaphylaxis. Methods: We carried out the health check-up on laboratory animal allergy (LAA) by questionnaires and specific-IgE antibody test for 555 rodents and/or rabbit handlers from whom informed consent was obtained. Result: Prevalence of positive IgE antibody higher than class 1 to mice, rats, hamsters, guinea pigs, and/or rabbits in the examinees was 14.1% (62/441), 17.9% (50/279), 18.8% (6/32), 17.4% (4/23), and 11.3% (12/106), respectively. Moreover, among users of mouse, those who had allergic symptoms during contact with animals resulted in significantly higher positive rate for anti-mouse IgE antibody test than the other (38.1% vs 8.8%, p<0.01). Conclusion: Health check-up including measurement of specific-IgE antibody against laboratory animals is useful for understanding allergic sensitization. - Rikkunshito, a Traditional Japanese Kampo Medicine, Ameliorates the Decrease in Feeding Behavior in Aged Mice Exposed to Stress via Enhancement of Endogenous Ghrelin Production

Japanese, Scientific journal, A 70-year-old male, who had undergone resection of gastric malignant lymphoma in 1992, presented with cervical lymph node swelling in January 2008. Pathological examination of the lymph node biopsy demonstrated recurrence of malignant lymphoma, and he was treated with the R-CHOP regimen. Although he did not develop fever during the first through third course of R-CHOP, from the fourth course, he repeatedly demonstrated fever over 38°C for about one week after each course of chemotherapy, despite the absence of neutropenia. Helicobacter cinaedi infection was confirmed by blood culture each time. Although it is difficult to diagnose Helicobacter cinaedi infection by the standard culture method, increased numbers of recent reports especially in immunocompromised patients have emphasized the importance of diagnosing Helicobacter cinaedi infection. - Undiagnosed collecting duct carcinoma presenting as meningeal carcinomatosis and multiple bone metastases

English, Scientific journal, A 59-year-old woman presented with ascites and intraperitoneal lymph node swelling. Pathological examination of the lymph node revealed follicular lymphoma. After a lymph node biopsy, she developed atypical genital bleeding, multiple endocrine disorders, polyneuropathy with a high plasma level of vascular endothelial growth factor (VEGF), and was diagnosed with POEMS syndrome. Following administration of methyl prednisolone, ascites immediately decreased and her performance status improved; however, about 18 months later, renal failure occurred, and she died despite increased steroid dosage. Lymph node swelling is often found in POEMS syndrome; however, its histological appearance is not well known, and it is very rare to be concomitant with malignant lymphoma. Therefore, it is important to perform a lymph node biopsy and investigate it in relation with VEGF. - Selective Delivery of siRNA Nanoparticles Targeting MEK Attenuates Experimental Pulmonary Hypertension

English, Summary international conference - 補中益気湯の作用メカニズム ~高齢低栄養患者における体力増強~
名畑 美和; 最上 祥子; 藤塚 直樹; 大西 俊介; 武田 宏司, 外科と代謝・栄養, 59, 2, 48, 51, 15 Apr. 2025
低栄養は病後・術後の回復力を弱め,感染症や死亡のリスクを高める.高年齢では栄養サポートによる改善効果が低いことが臨床や実験動物で報告されており,低栄養状態に陥ったときの代償機構が働きにくい.そのため,高齢患者の栄養管理には特に注意が必要である.補給されたアミノ酸の代謝にはオートファジー活性やミトコンドリアの品質管理が重要であるが,加齢によりこれらの機能が低下し,活動・生存に必要なエネルギーが不足しやすくなると考えられる.
補中益気湯は病後・術後の体力増強に処方される漢方薬であり,高齢患者において免疫状態や栄養状態の改善作用が報告されている.本稿では,加齢と栄養の観点から補中益気湯の作用機序を概説する., 日本外科代謝栄養学会, Japanese - 消化器内視鏡医が挑む,産学官連携によるデバイス開発の最前線~現状とそこから見える課題~

実験動物取り扱い関係者においてみられる職業性アレルギーである実験動物アレルギーについて、本学(大学)では、平成22年度に実験中にマウスに咬まれてアナフィラキシーショックを起こした事例が発生したことを機に、23年度より毎年、動物実験従事者のうち希望者に対し取り扱い動物の特異的IgE抗体検査を含むアレルギー健診を実施しており、今回、23年度から5年間連続してアレルギー健診を受診した21名(男性10名、女性11名、平均年齢42.0±10.6歳)を対象に、経年的解析を行った。その結果、5年間連続して同種の抗体検査を実施した者は、マウスIgE抗体19名、ラットIgE抗体10名、ウサギIgE抗体3名で、マウス、ラットのIgE抗体陽性率は有意差はなく横ばい状態であった。また、個人間での抗体価の変動についても、マウス、ラットともに受診者の約60%は陰性のまま推移していた。, (公社)全国大学保健管理協会, Japanese - DPP-IV活性により蛍光を発するプローブによる頭頸部扁平上皮表在がんの検出

本学の2014年定期健診で肥満と判定された学生22名にBDHQ調査を行い、コントロール群11名と比較した。結果、「摂取エネルギー」「炭水化物」「脂質」などの栄養素に有意な群間差はなかったが、食品では「緑黄色野菜」「漬物」「アイスクリーム」「果物」「洋菓子」の摂取量が肥満群で有意に少なかった。BDHQの結果報告には、おおよその信頼度を示す数値として摂取エネルギーの推定申告誤差が表示されており、±30%の範囲であれば、ある程度信頼度が高いとされる。今回の調査では、両群ともに過少申告者が存在したが、肥満群は-30%以上の割合がコントロール群より多く、信頼度が低かった(過少申告率が高かった)。肥満群には栄養・保健指導を行い、4ヵ月後に再度BDHQ調査を行ったところ、過少申告率は更に高くなっていた。, (公社)全国大学保健管理協会, Japanese - 消化管疾患における再生医療の最前線 羊膜由来間葉系幹細胞を用いた難治性腸炎に対する新規治療法の開発

2009年4月〜2014年7月に類内膜腺癌G1または複雑型子宮内膜異型増殖症(AEH)に対し高用量medroxyprogesterone(MPA)療法を施行した7例(年齢中央値34歳)の奏効率、再発の有無、治療後の妊娠出産の有無を後ろ向きに検討した。MPA投与量の中央値は600mg/日であった。MPA療法の効果判定は、子宮内膜全面掻爬による病理組織診断で行い、奏効率は85.7%、再発率は83.3%であった。再発までの期間の中央値は7ヵ月であり、そのうちMPAの再投与を行った症例が4例、最終的に手術を施行した症例が4例であった。出産に至ったのは1例のみであった。AEHおよび類内膜腺癌に対する高用量MPA療法は、奏効率は高いが再発率も高く、挙児希望があれば可及的早期の妊娠を考慮することが望ましいと考えられた。, 「産婦人科の進歩」編集室, Japanese - 高度肥満学生における高感度CRPの測定意義について

子宮頸がんワクチン接種は、2013年4月から予防接種法改正で定期接種となったが、副反応により安全性が問われ、同年6月14日に厚労省は積極的勧奨を中止した。A大学保健センターでは、2013年6月上旬から子宮頸がんワクチン未接種の1年生を対象に自費でのワクチン接種を開始し、希望者は当初25名いたが、厚労省からの通達後、途中キャンセルが相次ぎ、ワクチン接種全3回の実施に至ったのは18名であった。今回、この18名のうち同意が得られた12名を対象としてワクチン接種に関する半構造化インタビューを行い、語られた内容をカテゴリー化した。結果、『接種行動を妨げる不安』『実施の動機づけとなった要因』という2つのコアカテゴリーが抽出された。前者を構成するカテゴリーとして【様々な情報の不確かさ】【成長過程にある思春期の影響】【実施に至るまでの葛藤】があり、後者を構成するカテゴリーとして【病気の心配から必要性を判断】【家族との話し合い】【安心できる環境が重要】【安心・安全なワクチン接種の実際】があった。, 日本看護学会, Japanese - 本学での子宮頸がんワクチン接種実施報告 不安と疼痛の影響から考えられたこと

本学保健センターでは、子宮頸がんワクチン接種を希望する新入生女子24名に対して平成25年6月上旬に1回目の接種をしていたが、同年6月14日に厚労省が積極的勧奨を差し控えたため、7名が途中キャンセルした。今回、キャンセルした学生を含む24名の接種に対する不安について、接種前後の収縮期血圧を指標に調査するとともに、接種時の疼痛についてVAS(0〜10)で調査した。結果、収縮期血圧の平均値は、1回目の接種前が114.3、接種後107、2回目の接種前103.5、接種後99、3回目の接種前105.1、接種後105.6であり、1回目の接種前が最も高く、1回目と2回目は接種前が接種後より高値であったが、3回目は接種前後で差異を認めなかった。VASは、1回目が「0」7名、「1」1名、「2」1名、「3」2名、「5」12名、「6」1名、2回目(19名)が「2」1名、「3」3名、「4」1名、「5」9名、「6」5名、3回目(18名)が「1」4名、「2」2名、「4」2名、「5」7名、「6」2名、「7」1名であった。, (公社)全国大学保健管理協会, Japanese - 動物実験従事者におけるアレルギー健診3年分の経年的解析

子宮頸がんワクチン定期接種導入前の新入生のワクチン接種率を把握し、どのようなニーズがあるか検討した。入学前接種率は57.1%で、今後接種を考えていると答えた未接種者は71.8%であった。接種を考えない理由では「価格」が一番多く(34%)、「副反応」を理由に挙げたのは11%であった。ワクチンについての情報源は、女子は学校と家族が多く、男子は学校の他にTVが多かった。1回目の接種直後に「積極的勧奨の中止」の報道があり、25例の申込みのうち、最終の1例が未接種で辞退、5例が2回目以降の接種を辞退した。ワクチンを接種する際、保護者特に母親の理解が必要で、今回の調査でも中止という選択も母親の意向が強かったことが窺えた。, (公社)全国大学保健管理協会, Japanese - 定期健康診断の血圧測定における本学の取り組み 高血圧の偽陽性の学生を少なくするために

定期健康診断時(定健)の尿検査や再検査の結果について、一般学生(日本国籍)と比較し、留学生における尿検査有所見の傾向について検討した。定健尿検査を受診した学生31555例を一般学生と留学生に分けて検討した。定健尿検査(1回目)の再検該当者は、一般学生は平均3.2%であったが、留学生平均7.7%と高かった。さらに、男女別では、女性の留学生に高い傾向が見られた。再検該当項目別の陽性率は、尿潜血賜性は留学生及び男女、特に女性で高かった。再検受診者のうち、他医療機関へ紹介した紹介率は、留学生が平均5割と高いが、医療機閣からの返信が来た返信率は、一般学生の方が高かった。医療機関からの返信内容では、異常なしと血尿が多い傾向にあった。留学生の受診者数でもっとも多いのがアジアで、再検該当率、受診率最多は中国で次いで韓国、インドネシアに多く多かった。, (公社)全国大学保健管理協会, Japanese - FGIDの病態生理学と脳腸相関研究の進歩 ストレスによる胃機能異常にはグレリンシグナルの異常が関与する

下部消化管内視鏡検査に伴う術者の汚染リスクについて検討するため、術者11名にフェースガード付マスクを着用させ、内視鏡検査102例実施後の水滴付着の有無および面積、個数を調べた。その結果、18例で水滴付着を認め、うち17例は検査経験3年以下の術者によるものであった。検査状況でみると、鉗子口の操作回数に伴って水滴付着陽性率は増加し、水滴面積も増大する傾向にあった。鉗子口の操作数を、鉗子を入れた回数と注射器を用いた水の注入回数の和とし、4回以下の群と5回以上の群で比較したところ、5回以上群で有意に水滴数が多く、水滴面積も大きかった。水滴は全30滴中、20滴がフェースガードの左側に付着していた。検査時間(30分未満/以上)、検査形態(通常検査/緊急検査/EMR・ポリペクトミー)、液体吸引量(200ml未満/以上)と水滴数、水滴面積に有意差はなく関係は認めなかった。また、術者の身長(170cm未満/以上)とも関係は認めなかった。, (一社)日本消化器内視鏡学会, Japanese - 消化器病における漢方治療のエビデンスを目指して 六君子湯は社会的隔離による食欲不振を改善する

50歳代男。主訴は食道腫瘍の増大で、腫瘍は20年前の検診で指摘され、15年前の生検にて食道平滑筋腫と診断され経過観察中であった。食道バリウム造影および上部消化管内視鏡検査では胸部中部食道後壁になだらかな隆起性病変を認め、隆起部のヨード不染帯からの生検では強い異型を認めた。超音波内視鏡では第二層由来の内部均一な低エコー腫瘤を認めたため、食道癌と食道平滑筋腫の合併と考え内視鏡的粘膜下層剥離術により一括切除した。病理組織学的に平滑筋腫の直上上皮粘膜にcarcinoma in situを認めT1a-EP食道癌と診断した。, (一社)日本消化器内視鏡学会, Japanese - 悪性リンパ腫の化学療法中に繰り返し発症したHelicobacter cinaedi感染症

Japanese, Book review - Downregulation and growth inhibitory effect of epithelial-type Krüppel-like transcription factor KLF4, but not KLF5, in bladder cancer.
Shunsuke Ohnishi; Sumiko Ohnami; Friedrich Laub; Kazunori Aoki; Koichi Suzuki; Yae Kanai; Kazunori Haga; Masahiro Asaka; Francesco Ramirez; Teruhiko Yoshida, Biochemical and biophysical research communications, 308, 2, 251, 6, 22 Aug. 2003, [International Magazine]
Krüppel-like factors (KLFs) are key transcriptional regulators of cell differentiation and proliferation. Among the KLF family, the expression of KLF4 (GKLF) and KLF5 (IKLF) is highly restricted in the epithelial cells of several organs such as the gut and skin, and it has been reported that these epithelial-type KLF genes may be involved in colon carcinogenesis. Recently we found that Klf4 and Klf5 genes were significantly expressed in the developmental bladder epithelium of mice as well. Therefore, in this report we studied the involvement of the KLF4 and KLF5 genes in bladder carcinogenesis. First, we analyzed the expression of KLF4 and KLF5 in a variety of human bladder cancer cell lines and surgical specimens by RNA blot and in situ hybridization analyses. Both genes were highly expressed in the normal bladder epithelium, whereas KLF4, but not KLF5, was frequently downregulated in bladder cancer cell lines and cancer tissues. We then transduced the KLF4 and KLF5 genes into the bladder cancer cell lines using adenoviral vectors to examine the biological activities of the genes on those cells. The transduction of KLF4, but not KLF5, suppressed cell growth and induced apoptosis. Our study suggests that inactivation of KLF4 is one of the frequent steps towards bladder carcinogenesis., English - CTHAで低吸収域を示す肝結節性病変

本研究の目的は、胆管欠損部に生体吸収性胆管代替物(Bioabsorbable bile duct substitute: BBDS)を移植し、その部位に胆管を再生させる新規低侵襲治療法の開発である。現在、外科治療の方向性は機能温存および低侵襲にあるが、肝外胆管欠損の治療法は、乳頭部機能を廃絶した胆管―腸再建が通常行われ、機能温存の方向にはない。この再建法では、逆行性胆管炎が起こり理想的ではなく、他の治療法が求められている。本研究では、胆管欠損部を直接修復可能で、その部位に狭窄なく胆管再生が可能な胆管再建用BBDSの開発を目指す。具体的には、BBDSを用い、肝門部領域胆管癌手術の低侵襲化を目指し、Y字(左右肝管を模倣)に胆管を再生させること、さらに内視鏡的に胆管欠損部を修復させること(腹腔鏡下胆嚢摘出術時の胆管損傷治療を想定)が可能かを検討し、胆管系疾患に対する新規低侵襲治療法を開発する。
本年度は、BBDSを用いて、Y字に胆管を再生させる手技の実験研究を行った。(外部の動物実験施設にて)。本BBDSにて、肝外胆管を再生させることは可能となったが、確実にY字に再生させることにおいては、さらなる改善が必要である段階である(時々、再生胆管の狭窄が認められた)。内視鏡を用いた、胆管修復、再生の研究は、順調に進行しており、論文作成の段階である。
生体吸収性材料の消化器系疾患への応用は、一部、吻合部組織補強材として用いられているが、始まったばかりであり、本BBDSの臨床研究施行のための実験を重ねていく予定である。

【背景】脊髄損傷に対する再生治療・細胞治療は多くの基礎研究において有効性が報告され始めているが, その作用機序は全身の炎症制御や損傷部位への幹細胞生着によるネットワークの回復など多岐にわたると考えられている. 近年, 全身の免疫センターとしての機能を有する腸管と他臓器の関連が注目されており, 脊髄損傷においても腸管との関連(脊髄-腸相関)が報告されているが, 幹細胞投与がこの相関にどのように関与しているかは未だ明らかになっていない. 本研究では, 急性期脊髄損傷に対する羊膜由来間葉系幹細胞(AMSC)静脈投与が, “脊髄-腸相関”に与える影響を検討した.
【方法】SDラットを用い, Th6/7高位で, クリップ圧挫脊髄損傷モデルを作成した. 脊髄損傷の翌日, 一定以上の麻痺を認めたラットに対し, 無作為にヒトAMSC(1x107個, A群)または生理食塩水(C群)を尾静脈投与した. AMSCの分布は, XenoLight DiRで標識し, Fusionでin-vivo imagingを行った. 腸管評価は3日後と2週間後に, 運動機能評価は4週間後まで行い, その後に病理学的検討を加えた.
【結果】AMSCは1週間後まで主に肺と肝臓に集積していたが, 急性期には脊髄内にも確認された. A群はC群に比較し, 脊髄損傷3日後以降で回腸の絨毛構造の改善を認めた. 運動機能は2週以降, A群で有意に改善し, 病理学的評価においても, 損傷部位の縮小および炎症細胞浸潤が減少していた.
【考察・結語】本研究の結果から, 脊髄損傷により回腸絨毛構造が悪化するが, 羊膜細胞投与により, 運動機能回復に先立って回腸絨毛構造が改善することが明らかとなった. 今後、bacterial translocationの関与を検討する

間葉系幹細胞は、出産時に廃棄される羊膜にも存在していることが知られており、次世代の再生医療材料として期待されている。申請者らは、ヒト卵膜から短期 間で簡便に間葉系幹細胞 を分離培養する技術を確立し、腸炎、肝炎、膵炎などの複数の炎症性疾患動物モデルに対して、細胞ならびにその培養上清を投与した ところ、いずれも高い治療効果を発揮することを明らかにしてきた。本研究では、羊膜由来間葉系幹細胞のもつ新規抗炎症因子の同定を行い、難治性として知られる炎症性腸疾患における新規治療効果の検討を探索することを目的としている。そこで本研究では、羊膜MSC由来新規物質の抗炎症効果の検証するために培養細胞を用いて検証を行った。具体的には以下の通り実施した。
マウス由来マクロファージを用いて、LPSで刺激後、羊膜MSC由来新規物質を処理し、LPS刺激後に産生される複数の炎症性サイトカインをELISA法で検証した。結果、LPS刺激後のマクロファージに羊膜MSC由来新規物質処理するとTNF-αやIL-6などの炎症性サイトカインの発現が著しく低下したほか、培養上清中の炎症性サイトカインの産生も低下していた。さらに、ウエスタンブロット法を用いて、炎症性サイトカインの産生に重要な転写因子であるNF-kBやIkBなどの活性化を確認した。結果、LPS刺激後のマクロファージではNF-kBやIkBなどの活性化が確認されたが、羊膜MSC由来新規物質を処理するとこれら転写因子の活性化が抑制されていることが明らかとなった。これらのことから、in vitroの系を用いた細胞培養実験において羊膜MSC由来新規物質の抗炎症効果が明らかとなった。

Mesenchymal stem cells have been reported to be a promising cell source in regenerative medicine. We analyzed secretory factors from amnion-derived mesenchymal stem cells, and identified eicosapentaenoic acid (EPA) and its metabolite resovlin E1 (RvE1).
When we administered EPA to LPS-induced premature birth model rats, it improved premature birth, and the concentrations of EPA and RvE1 in amniotic fluid were recovered. These results suggest that EPA prevents preterm birth via RvE1.

Recent advances in endoscopic diagnostics and techniques have enabled early detection and resection of gastrointestinal cancer. But it is still difficult to detect and diagnose early adenocarcinoma of the esophagogastric junction (EGJ) using conventional endoscopy or image-enhanced endoscopy.
Recently, a glutamylprolyl hydroxymethyl rhodamine green (EP-HMRG) fluorescent probe that can be enzymatically activated by a dipeptidyl peptidase (DPP)-IV expressed on the surface of several cancers has been developed.This study showed that the tumor lesions were visualized within a few minutes after the application of EP-HMRG and suggested that Fluorescence imaging with EP-HMRG could be useful for the detection of early EGJ adenocarcinoma lesions.

Endoscopic submucosal dissection (ESD) for esophageal cancer often causes postoperative stricture when more than three-quarters of the circumference of the esophagus is dissected. Mesenchymal stem cells are a valuable cell source in regenerative medicine, and conditioned medium (CM) obtained from mesenchymal stem cells reportedly inhibits inflammation. In this study, we evaluated whether CM could prevent esophageal stricture after ESD.
In a pig model of esophageal stricture after ESD, CM gel prevented esophageal stricture formation by suppressing myofibroblast activation and fibrosis following the infiltration of neutrophils and macrophages in acute phase. Oral administration of CM gel would be a promising treatment for the prevention of post-ESD stricture. We are currently evaluating the effect of CM on the prevention of re-stricture after balloon dilation.

The present study was conducted to search for therapeutic candidates (peptides, small molecules and miRNAs) to target liver fibrosis and activation of hepatic stellate cells and to analyze their mechanisms of action. The main results are as follows; (1) We confirmed suppressive effects of liver fibrosis and inflammation of exosomes derived from the culture supernatant of human amniotic membrane-derived mesenchymal stem cells. (2) palmitoylethanolamide (PEA) inhibited activation of hepatic stellate cells through PPAR-independent mechanisms. (3) Comprehensive glycan modification structure analysis indentified fucosyl modification of serum proteins as markers that associate with NAFL to NASH progression. (4) Comprehensive analysis of microRNAs related to cultured hepatic stellate cell activation identified miRNAs that up- or down-regulated in activated stellate cells.

γ-glutamyltranspeptidase (GGT), a cell surface enzyme, is overexpressed in several cancers, and it has been reported that γ-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG), a fluorescent targeting agent which can be enzymatically activated and becomes fluorescent after cleavage of a GGT-specific sequence. We investigated whether early HNSCC can be detected by applying gGlu-HMRG to clinical samples.
All four gGlu-HMRG-applied cell lines emitted green fluorescence. Immunohistological examination demonstrated that GGT was highly expressed in HNSCC of the recent three ESD cases but barely expressed in the normal mucosa. Fluorescence imaging showed that iodine-voiding lesions became fluorescent within a few minutes after application of gGlu-HMRG in all eight resected cases. Tumor ROI fluorescence intensity was significantly higher than in the normal mucosa five minutes after gGlu-HMRG application. Fluorescence imaging with gGlu-HMRG would be useful for early detection of HNSCC.

We investigate the role of macrophage migration inhibitory factor (MIF) in non alcoholic steatohepatitis (NASH) using animal model. Methionine and choline-deficient diet(MCD) induces NASH in mice. The expression of MIF was up-regulated in liver of mice given MCD. However, ISO-1, an inhibitor of MIF bioactivity, did not ameliorated the severity of NASH in mice. In another hepatitis model induced by acetaminophene, ISO-1 reduced the severity of liver injury and decrease the level of inflammatory mediater. Taken together, our data suggest that the role of MIF is perplexing in NASH.

Objectives: We investigated the effect of rat FM-derived mesenchymal stem cells (FM-MSCs) and human amnion-derived MSCs (AMSCs) on the therapeutic effects in rats with acute and chronic pancreatitis.
Methods: Acute pancreatitis was induced by intraductal injection of taurocholate, and rat FM-MSCs were transplanted intravenously. Chronic pancreatitis was induced by intravenous injection of 5 mg/kg dibutyltin dichloride, and human AMSCs were transplanted intravenously.
Results: Transplantation of rat FM-MSCs significantly reduced the histological score and infiltration of CD68-positive macrophages in the rat pancreas. Human AMSC transplantation significantly decreased the expression of MCP-1 and attenuated the downregulation of amylase expression in the pancreas. Conclusions: Transplantation of FM-MSCs and AMSCs suppressed the inflammatory reaction of acute and chronic pancreatitis in rats.

Radiation enteritis is caused by radiation therapy to cancer patients, or by an accident in nuclear power plants. The aim of the study was to explore the new strategy to treat radiation enteritis, and I investigated the effect of fetal membrane-derived mesenchymal stem cells in vivo and in vitro.
Treatment with human amnion-derived mesenchymal stem cells in rats with radiation enteritis ameliorated histological observations and the expression of proinflammatory cytokines. In vitro experiments demonstrated that radiation-induced cell injury was suppressed by human amnion-derived mesenchymal stem cells.
Taken together, amnion-derived mesenchymal cells could be considered as a new treatment for radiation enteritis.

肺動脈性肺高血圧症は、肺血管内皮細胞の機能障害により肺動脈の収縮や肺血管内皮・平滑筋細胞の増殖を来たす難治性疾患である。既存の治療薬は血管拡張を主な作用点としており、治療抵抗例が存在するため、我々は治療のターゲットを主たる病因である肺動脈の血管内皮・血管平滑筋細胞の増殖へ転換する必要があると考えた。肺高血圧症では、細胞増殖・分化を制御するMAPKシグナリングが病態へ関与していると考えられており、まずこのシグナル蛋白であるMEKを標的としたsiRNAをデサインし、その効果を確認した。ラットMEK1および2の双方に相同性をもつ21merのsiRNAを合成し、培養ラット血管平滑筋細胞(A7r5)にリポフェクションさせ、標的遺伝子、蛋白の抑制効率をそれぞれ定量的Real time PCR法、Western blotting法により検討したところ、siRNA濃度が1nMの低濃度でも85%以上の抑制効率を示し、また濃度10nMにおける経時的検討では少なくとも96時間以上その抑制効果が持続していた。次に、このsiRNAの血管平滑筋細胞に対する増殖抑制効果を、MAPKカスケードを下流とする増殖因子であるPDGF-BB刺激下にMTS assayを用いて検討したところ、siRNA濃度依存的に血管平滑筋細胞の増殖が抑制されていた。さらに、アポトーシス誘導効果をカスパーゼ3および7の細胞内活性を測定し検討したところ、やはり濃度依存的にアポトーシス誘導が起こっていた。以上より、我々のデザインした合成siRNAはラノト血管平滑筋細胞の標的蛋白合成を効率的に阻害し、期待された増殖抑制およびアポトーシス誘導の表現型を示すことが証明された。現在、このsiRNAを脂質化合物を用いて生体内での安定性を確保した薬物送達システムを開発中であり、ラット肺高血圧モデルを用いて標的となる肺動脈への導入効率を検討する予定である。
