English, Scientific journal, BACKGROUND: Lysophosphatidylethanolamines (lyso-PEs) are the partial hydrolysis products of phosphatidylethanolamine. Although lyso-PEs are important biomarkers in various diseases, their determination is limited by the lack of simple and efficient quantification methods. This study aims to develop an improved quantitative method for the determination of lyso-PEs and its application to an epidemiological study. METHODS: Single reaction monitoring channels by collision-induced dissociation for seven lyso-PEs were established using liquid chromatography-tandem mass spectrometry. Plasma lyso-PEs were extracted with a single-phase method using an isotopically labeled internal standard for quantification. The proposed method was adopted to define lyso-PEs in plasma samples of children aged 9-12 years living in Sapporo, Japan. RESULTS: The limit of detection and limit of quantification for each lyso-PE ranged between 0.001-0.015 and 0.002-0.031 pmol/μL, respectively. Recoveries were found to be > 91% for all the species. The analysis results of children's plasma showed that the total lyso-PE concentrations in boys (n = 181) and girls (n = 161) were 11.53 and 11.00 pmol/μL (median), respectively. Participants were further classified by the percentage of overweight and subgrouped as underweight (n = 12), normal range (n = 292), or overweight (n = 38). Interestingly, the reduction of lyso-PE 16:0 and increased lyso-PE 22:6 were observed in overweight children compared with normal range (Fold change: 0.909 and 1.174, respectively). CONCLUSIONS: This study successfully established a simple quantitative method to determine lyso-PE concentrations. Furthermore, our method revealed the possible relation between plasma lyso-PEs and overweight status. - Relationships of the Surface Charge of Low-Density Lipoprotein (LDL) with the Serum LDL-Cholesterol and Atherosclerosis Levels in a Japanese Population: The DOSANCO Health Study.

English, Scientific journal, AIM: This study investigated the associations of the surface charge of low-density lipoprotein (LDL) with the serum LDL-cholesterol and atherosclerosis levels in a community-based Japanese population. METHODS: The study had a cross-sectional design and included 409 community residents aged 35-79 years who did not take medications for dyslipidemia. The potential electric charge of LDL and the zeta potential, which indicate the surface charge of LDL, were measured by laser Doppler microelectrophoresis. The correlations of the zeta potential of LDL (-mV) with the serum LDL-cholesterol levels (mg/dL), cardio-ankle vascular index (CAVI), and serum high-sensitivity C-reactive protein (hsCRP) levels (log-transformed values, mg/L) were examined using Pearson's correlation coefficient (r). Linear regression models were constructed to examine these associations after adjusting for potential confounding factors. RESULTS: A total of 201 subjects with correctly stored samples were included in the primary analysis for zeta potential measurement. An inverse correlation was observed between the LDL zeta potential and the serum LDL-cholesterol levels (r=-0.20; p=0.004). This inverse association was observed after adjusting for sex, age, dietary cholesterol intake, smoking status, alcohol intake, body mass index, and the serum levels of the major classes of free fatty acids (standardized β=-6.94; p=0.005). However, the zeta potential of LDL showed almost no association with CAVI or the serum hsCRP levels. Similar patterns were observed in the 208 subjects with compromised samples as well as all the original 409 subjects. CONCLUSION: A higher electronegative surface charge of LDL was associated with lower serum LDL-cholesterol levels in the general Japanese population. - Increased phosphatidylcholine and its hydroperoxides in serum low-density lipoproteins from patients with non-alcoholic steatohepatitis.

English, Scientific journal, BACKGROUND: Non-alcoholic fatty liver disease is classified into simple steatosis (SS) and non-alcoholic steatohepatitis (NASH) according to histological findings from liver biopsies. Phosphatidylcholine (PC), the main component of phospholipids in serum lipoproteins, is easily oxidized to phosphatidylcholine hydroperoxide (PC-OOH). Although a lipid composition in the low-density lipoproteins (LDL) from patients with NASH could be abnormal, it remains unclear. Here, to better understand the characteristics of lipids in the LDL from NASH and SS, we compared the composition of PC and PC-OOH species in LDL particles (LDL-PC, LDL-PCOOH) from these patients, then clarified the association between these lipids and NASH severity. METHODS: The serum samples from patients with NASH (female, n = 9) and SS (female, n = 4; male, n = 2) were used for isolation of LDL. Total lipids were extracted from isolated LDL, and the species of PC and PC-OOH were measured using liquid chromatography-mass spectrometry/mass spectrometry. RESULTS: The sum of LDL-PC and the sum of LDL-PCOOH were significantly higher in NASH than in SS. Several LDL-PC (PC 32:0, 32:1, 32:2, 34:3, 36:2, sum of PC with saturated fatty acyl chains and sum of LDL-PC with polyunsaturated fatty acyl chains) and several LDL-PCOOH (34:2, 36:2, 36:3 and total) were increased significantly with increasing fibrosis score. In particular, a series of LDL-PCOOH were more reflective of the severity of fibrosis score. CONCLUSIONS: LDL-PC and LDL-PCOOH species were strongly correlated with the fibrosis score in NASH, which suggests that abnormal LDL is involved in the development of liver fibrosis. - Kaempferol Improves Cardiolipin and ATP in Hepatic Cells: A Cellular Model Perspective in the Context of Metabolic Dysfunction-Associated Steatotic Liver Disease.

English, Scientific journal, Targeting mitochondrial function is a promising approach to prevent metabolic dysfunction-associated steatotic liver disease (MASLD). Cardiolipin (CL) is a unique lipid comprising four fatty acyl chains localized in the mitochondrial inner membrane. CL is a crucial phospholipid in mitochondrial function, and MASLD exhibits CL-related anomalies. Kaempferol (KMP), a natural flavonoid, has hepatoprotective and mitochondrial function-improving effects; however, its influence on CL metabolism in fatty liver conditions is unknown. In this study, we investigated the effects of KMP on mitochondrial function, focusing on CL metabolism in a fatty liver cell model (linoleic-acid-loaded C3A cell). KMP promoted mitochondrial respiratory functions such as ATP production, basal respiration, and proton leak. KMP also increased the gene expression levels of CPT1A and PPARGC1A, which are involved in mitochondrial β-oxidation. Comprehensive quantification of CL species and related molecules via liquid chromatography/mass spectrometry showed that KMP increased not only total CL content but also CL72:8, which strongly favors ATP production. Furthermore, KMP improved the monolysocardiolipin (MLCL)/CL ratio, an indicator of mitochondrial function. Our results suggest that KMP promotes energy production in a fatty liver cell model, associated with improvement in mitochondrial CL profile, and can serve as a potential nutrition factor in preventing MASLD. - Identification of a β-Carboline Alkaloid from Chemoselectively Derived Vanilla Bean Extract and Its Prevention of Lipid Droplet Accumulation in Human Hepatocytes (HepG2)

English, Scientific journal, Targeting bioactive compounds to prevent lipid droplet accumulation in the liver, we explored an antioxidative extract from vanilla bean (Vainilla planifolia) after chemo-selective derivatization through heating and acid modification. The chemical analysis of vanilla bean extract through chemoselective derivatization resulted in the identification of sixteen compounds (34–50) using LC-MS/MS analysis. A β-carboline alkaloid with a piperidine C-ring and a vanillin moiety at C-1 (34) was identified by molecular networking and diagnostic fragmentation filtering approaches. β-carboline alkaloid 34 exhibited significant inhibitory activity of lipid droplet accumulation (LDAI) in oleic acid-loaded hepatocellular carcinoma HepG2 cells. The LDAI activity was associated with both activation of lipolysis and suppression of lipogenesis in the cells. The study indicates that crude plant extracts, following chemoselective derivatization, may contain bioactive compounds that could be beneficial in preventing hepatosteatosis and could serve as a source of lead compounds for drug development. This approach may be useful to investigate other mixtures of natural products and food resources. - A Pacific Oyster-Derived Antioxidant, DHMBA, Protects Renal Tubular HK-2 Cells against Oxidative Stress via Reduction of Mitochondrial ROS Production and Fragmentation.

English, Scientific journal, The kidney contains numerous mitochondria in proximal tubular cells that provide energy for tubular secretion and reabsorption. Mitochondrial injury and consequent excessive reactive oxygen species (ROS) production can cause tubular damage and play a major role in the pathogenesis of kidney diseases, including diabetic nephropathy. Accordingly, bioactive compounds that protect the renal tubular mitochondria from ROS are desirable. Here, we aimed to report 3,5-dihydroxy-4-methoxybenzyl alcohol (DHMBA), isolated from the Pacific oyster (Crassostrea gigas) as a potentially useful compound. In human renal tubular HK-2 cells, DHMBA significantly mitigated the cytotoxicity induced by the ROS inducer L-buthionine-(S, R)-sulfoximine (BSO). DHMBA reduced the mitochondrial ROS production and subsequently regulated mitochondrial homeostasis, including mitochondrial biogenesis, fusion/fission balance, and mitophagy; DHMBA also enhanced mitochondrial respiration in BSO-treated cells. These findings highlight the potential of DHMBA to protect renal tubular mitochondrial function against oxidative stress. - Oxidized Low-Density Lipoproteins Trigger Hepatocellular Oxidative Stress with the Formation of Cholesteryl Ester Hydroperoxide-Enriched Lipid Droplets

Scientific journal, Oxidized low-density lipoproteins (oxLDLs) induce oxidative stress in the liver tissue, leading to hepatic steatosis, inflammation, and fibrosis. Precise information on the role of oxLDL in this process is needed to establish strategies for the prevention and management of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). Here, we report the effects of native LDL (nLDL) and oxLDL on lipid metabolism, lipid droplet formation, and gene expression in a human liver-derived C3A cell line. The results showed that nLDL induced lipid droplets enriched with cholesteryl ester (CE) and promoted triglyceride hydrolysis and inhibited oxidative degeneration of CE in association with the altered expression of LIPE, FASN, SCD1, ATGL, and CAT genes. In contrast, oxLDL showed a striking increase in lipid droplets enriched with CE hydroperoxides (CE-OOH) in association with the altered expression of SREBP1, FASN, and DGAT1. Phosphatidylcholine (PC)-OOH/PC was increased in oxLDL-supplemented cells as compared with other groups, suggesting that oxidative stress increased hepatocellular damage. Thus, intracellular lipid droplets enriched with CE-OOH appear to play a crucial role in NAFLD and NASH, triggered by oxLDL. We propose oxLDL as a novel therapeutic target and candidate biomarker for NAFLD and NASH. - リゾホスファチジルエタノールアミンと肝疾患

English, Scientific journal, Lysophosphatidylethanolamine (LPE) is a major lysophospholipid produced by phospholipids and binds to human serum albumin (HSA). LPEs may play various roles in vivo depending on the differences in their acyl chains. However, only few reports have been published on the biological functions of LPEs. Hence, we determined the exact relative abundance of the major LPEs in the serum of healthy participants (n = 8) using liquid chromatography-tandem mass spectrometry. Consequently, LPE 18:2 (24.1 ± 5.2%) was found to be the most abundant in serum. To understand the distribution of LPEs, the serum separated via gel-filtration high-performance liquid chromatography was subjected to quantitative measurement. LPEs were more observed in the albumin fraction than the lipoprotein fraction. We also performed a fluorescence displacement assay and an in silico molecular docking experiment using AutoDock to confirm the affinity and binding sites of the LPEs on HSA. The binding affinities of the LPEs for drug sites 1 and 2 on HSA were relatively low, with Ki values of approximately 11 and 3.8 μM, respectively. AutoDock analysis revealed the conformation of the LPEs bound to drug sites and the possibility of LPEs binding to other HSA sites. These findings could help to elucidate the biological and pathological functions of LPEs. - Food-Derived β-Carboline Alkaloids Ameliorate Lipid Droplet Accumulation in Human Hepatocytes.

English, Scientific journal, Lipid droplet accumulation (LDA) in hepatocytes is the initial stage of nonalcoholic fatty liver disease (NAFLD). In the search for natural compounds for the prevention of NAFLD, a series of β-carboline alkaloid derivatives, inspired by flazin and its derivative, newly identified in Crassostrea gigas Thunberg. extracts, were examined for LDA inhibition (LDAI) activity in oleic acid-loaded hepatocytes (HepG2). Eight compounds with a piperidine or pyridine C-ring were chemically synthesized (1-8). Among them, compounds 2 and 4 (flazin) with a carboxy group at C-3 and furfuryl alcohol moiety at C-1 showed low cytotoxicity and they exhibited significant LDAI activity. Compound 2 with piperidine C-ring was identified for the first time in C. gigas extract, and ameliorated the lipid accumulation with the LDAI value of 25.4%. Active compounds 2 and 4 significantly inhibited triacylglycerol species accumulation in cells. These compounds upregulated ATGL and downregulated SREBP1, FASN, and SCD1 genes, suggesting that they activated lipolysis and suppressed lipogenesis, respectively. These results suggest that β-carboline alkaloids, especially compounds 2 and 4, might be potentially useful for preventing NAFLD. - Simple and Sensitive Method for the Quantitative Determination of Lipid Hydroperoxides by Liquid Chromatography/Mass Spectrometry

English, Scientific journal, Serum fatty acids (FAs) exist in the four lipid fractions of triglycerides (TGs), phospholipids (PLs), cholesteryl esters (CEs) and free fatty acids (FFAs). Total fatty acids (TFAs) indicate the sum of FAs in them. In this study, four statistical analysis methods, which are independent component analysis (ICA), factor analysis, common principal component analysis (CPCA) and principal component analysis (PCA), were conducted to uncover food sources of FAs among the four lipid fractions (CE, FFA, and TG + PL). Among the methods, ICA provided the most suggestive results. To distinguish the animal fat intake from endogenous fatty acids, FFA variables in ICA and factor analysis were studied. ICA provided more distinct suggestions of FA food sources (endogenous, plant oil intake, animal fat intake, and fish oil intake) than factor analysis. Moreover, ICA was discovered as a new approach to distinguish animal FAs from endogenous FAs, which will have an impact on epidemiological studies. In addition, the correlation coefficients between a published dataset of food FA compositions and the loading values obtained in the present ICA study suggested specific foods as serum FA sources. In conclusion, we found that ICA is a useful tool to uncover food sources of serum FAs. - A mouse model of short-term, diet-induced fatty liver with abnormal cardiolipin remodeling via downregulated Tafazzin gene expression.

English, Scientific journal, BACKGROUND: Cardiolipin (CL) helps maintain mitochondrial structure and function. Here we investigated whether a high carbohydrate diet (HCD) fed to mice for a short term (5 days) can modulate the CL level including that of monolysoCL (MLCL) in the liver. RESULTS: Total CL in the HCD group was 22% lower than that in the normal chow diet (NCD) group (P <0.05). CL72:8 level strikingly decreased by 93% (P <0.0001), whereas total nascent CL (CLs other than CL72:8) increased (P <0.01) in the HCD group. Moreover, total MLCL in the HCD group increased by 2.4-fold compared with that in the NCD group (P <0.05). Tafazzin expression in the HCD group was significantly downregulated compared with that in the NCD group (P <0.05). A strong positive correlation between nascent CL and total MLCL (r = 0.955, P <0.0001), and a negative correlation between MLCL and Tafazzin expression (r = -0.593, P = 0.0883) were observed. CONCLUSION: HCD modulated fatty acid compositions of CL and MLCL via Tafazzin in the liver, which could lead to mitochondrial dysfunction. This model may be useful for elucidating the relationship between fatty liver and mitochondrial dysfunction. This article is protected by copyright.

English, Scientific journal, Lysophosphatidylethanolamines (LysoPEs) are the partial hydrolysis products of phosphatidylethanolamine. Despite the unique in vitro bioactivities of LysoPEs, there are limited reports on the pathophysiological role of LysoPEs in the serum, due to the lack of sensitive analytical methods for determination of each molecular species in clinical samples. Herein, we developed a highly sensitive quantitative method to profile the serum LysoPE species by liquid chromatography-tandem mass spectrometry (LC-MS/MS) with selected reaction monitoring (SRM). The internal standard (IS), chemically synthesized in-house, and the lineup of seven major LysoPE species were used in this study. The limits of detection and quantification for each LysoPE species ranged within 0.5-3.3 pmol/mL and 1.0-5.0 pmol/mL, respectively. The combined concentrations of LysoPEs in the serum from healthy subjects (n = 8) and the patients with non-alcoholic fatty liver diseases (NAFLD) including simple steatosis (SS, n = 9) and non-alcoholic steatohepatitis (NASH, n = 27) were 18.030 ± 3.832, 4.867 ± 1.852, and 5.497 ± 2.495 nmol/mL, respectively. The combined and individual concentrations of LysoPEs, except for LysoPE 18:0, significantly decreased in the patients with NAFLD compared with those for the healthy subjects. However, no significant difference was observed between the SS and NASH groups. Our proposed LC-MS/MS method is valid and has advantages of small sample volume, high sensitivity, and simultaneous absolute quantitation for multiple molecular species. This method may enable diagnostic evaluation and elucidation of the as-yet uncovered pathophysiological role of LysoPEs. - Low-Density Lipoprotein (LDL)-Triglyceride and Its Ratio to LDL-Cholesterol as Diagnostic Biomarkers for Nonalcoholic Steatohepatitis.

English, Scientific journal, BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the most common type of liver disease, but it is difficult to distinguish its pathogenic phenotype, nonalcoholic steatohepatitis (NASH), from nonalcoholic fatty liver (NAFL) without a liver biopsy. We analyzed serum lipids, including low-density lipoprotein triglyceride (LDL-TG), to elucidate their usefulness for diagnosing NASH. PATIENTS AND METHODS: Serum samples obtained from 35 NASH and 9 NAFL biopsy-confirmed patients and 6 healthy volunteers (HLT) were studied for 13 lipid-related markers and compared between HLT, NAFL, and NASH groups. The relationship between histological findings and the lipid markers was also analyzed. RESULTS: There were significant differences in triglyceride, LDL-TG, the ratio of LDL-TG to the LDL-cholesterol (LDL-TG/LDL-C), small dense LDL-C, and apolipoprotein E between the three groups. Among the 5 lipid components, serum LDL-TG level and the ratio of LDL-TG to the LDL-cholesterol (LDL-TG/LDL-C) were significantly elevated in NASH. The median concentrations of LDL-TG in HLT, NAFL, and NASH were 9, 15, and 20 mg/dL (P < 0.001), and those of LDL-TG/LDL-C were 0.097, 0.102, and 0.173 (P < 0.001), respectively. Although the degree of steatosis was not correlated with the LDL-TG/LDL-C, the ratio was significantly higher in patients with lobular inflammation (P = 0.071), ballooning (P = 0.031), and fibrosis (P < 0.001). The area under the receiver operating characteristic curve of the ratio for distinguishing NASH from NAFL was 0.857. The rest of studied markers showed no significant utility. CONCLUSION: Serum LDL-TG levels and the LDL-TG/LDL-C ratio might serve as simple and noninvasive diagnostic biomarkers for NASH. - Multivariate Analysis for Molecular Species of Cholesteryl Ester in the Human Serum.

English, Scientific journal, Cholesteryl ester (CE) is an ester of cholesterol and fatty acid (FA). Plasma CE reflects complicated metabolisms of cholesterol, phospholipids, lipoproteins, and dietary FAs. An informatics approach could be useful for analysis of the CE species. In this study, two basic dimension reduction methods, principal component analysis (PCA) and factor analysis, were applied to serum CE species determined by LC-MS/MS in a Japanese population (n = 545). PCA and factor analysis both reflected the size (concentration), food source, fat solubility, and biological aspect of the CE species. In a comparison between PCA (PC4) and factor analysis (factor 4), the latter was found to be more suggestive from a biological aspect of n-6 FAs. Cholesteryl docosahexaenoate (DHA) was found to be unique by a factor analysis, possibly relevant to the unique accumulation of DHA in the brain. An informatics approach, especially factor analysis, might be useful for the analysis of complicated metabolism of CE species in the serum. - Learning Effect of Diagnosing Depth of Invasion Using Non-Extension Sign in Early Gastric Cancer

English, Scientific journal, A fluorescence microscopic method for characterizing size, quantity, and oxidation of lipid droplets (LDs) in HepG2 cells was developed. LDs were induced by palmitic (PA), oleic (OA), or linoleic acids (LA) and stained with two fluorescent probes for neutral lipids and lipid peroxides. Each fatty acid increased the number of LDs and oxidized LDs (oxLDs) and the degree of LD oxidation time dependently, as well as increased intracellular triglyceride hydroperoxides. LDs induced by LA without 2,2'-azobis(2-amidinopropane)dihydrochloride (AAPH) showed the most significant oxidation degree over PA and OA, especially in large LDs (area ≥ 3 μm2, oxLD/LD = 52.3 ± 21.7%). Under this condition, two food-derived antioxidants were evaluated, and both of them significantly improved the LD characteristics. Moreover, chlorogenic acid reduced the quantity of large LDs by 74.0-87.6% in a dose-dependent manner. The proposed method provides a new approach to evaluate the effect of dietary antioxidants on LD characteristics. - 糖化がLDLの物性に与える影響について(Effect of glycation on the physical properties of low density-lipoprotein)

ウコン(ターメリック)に含まれるポリフェノールであるクルクミノイドのヒトにおける吸収・代謝・動態は不明である。我々は,血中クルクミノイドのUV検出高速液体クロマトグラフィー(HPLC)による定量法を開発し,ターメリック粉3g(クルクミノイド60~90mg含有)を服用した健常成人7名(m:f=-5:2,24±1歳)と市販ウコン錠(90%精製クルクミノイド480mg含有)を服用した健常成人7名(m:f=4:3,22±2歳)の血中抱合型並びに非抱合型のクルクミノイド(非還元型)を本法により測定した。ターメリック粉群では服用1時間後に最大血中濃度が142.9±63.7nmol/lに達した。一方,ウコン錠群では服用8時間に最大血中濃度が26.9±17.7nmol/lとなり,クルクミノイドの精製度が消化管吸収速度に影響する可能性が示唆された。酵素水解反応の結果から,非還元型クルクミノイドは大部分がグルクロン酸抱合体あるいはグルクロン酸と硫酸の二重抱合型として存在し,一部が遊離型として存在することが推測された。今回開発したHPLC法は,ウコン食品の薬理学的研究に有用なツールとなることが期待される。 Curcuminoids are the polyphenols contained in turmeric. They are getting more popular in Japan as an ingredient of health foods. However, little is known about the intestinal absorption, metabolites and pharmacokinetic profiles of orally administered curcuminoids in human. In this report, quantitative analyses of curcuminoids in human plasma after oral administration were done by using HPLC with the aid of synthetic curcuminoid derivatives as an internal standard. For non-reduced forms of curcuminoids, the average recoveries from plasma were 93.1%~114.8%, and the coefficients of variation were less than 16.2%. The enzymatic hydrolysis demonstrated that the non-reduced curcuminoids were glucuronides (50.0%) , glucuronide/ sulfate double conjugates (45.4%) and free (4.6%) at 1 hour after oral ingestion of 4 g turmeric powder. The maximum plasma concentrations of curcuminoids (non-reduced form) in the turmeric powder group (60~90 mg curcuminoids included, n=7) and the turmeric tablet group (90% purified curcuminoids 480 mg included, n=7) were 142.9 + 63.7 nmol/l (mean ± SD) at 1 hour and 26.9 ± 17.7 nmol/l (mean ± SD) at 8 hour, respectively, indicating the different intestinal absorption rates. The present method will serve as a useful analytical tool for pharmacological studies of curcuminoids., 日本臨床化学研究会, Japanese - 動的光散乱を用いた各種リポ蛋白粒径の簡易計測法の開発

我々が獲得したGll-6(抗体)を用いる酵素免疫学的測定法(Gll-6 ELISA)では、穏やかに酸化されたリポタンパク質を検出できる。以前の報告で、血清をゲルろ過HPLCで分離して本ELISAで測定したところ、重度肝疾患患者ではトリグリセリド高含有リポタンパク質の位置に、脂質異常症患者では大型LDLの位置に、健常者では小型LDLの位置にそれぞれピークが出現した。本年度では症例数を増やし、酸化リポタンパク質分布パターンの統計学的解析により確かな結果であることが確認された。
また、メタボリックシンドロームの肝における表現型とされる非アルコール性脂肪性肝炎(NASH)は単純性脂肪肝との鑑別が必須であるが、侵襲的な肝生検が用いられており、非侵襲的で良好な血液マーカーが無いことが問題視されてきた。我々はNASHと単純性脂肪肝をもつ患者において、NASH患者ではトリグリセリド高含有リポタンパク質の位置に、単純性脂肪肝の患者では脂質異常症患者のパターンと同じく、大型LDLの位置にそれぞれ酸化リポタンパク質のピークが観察された。よって、NASHと単純性脂肪肝患者における酸化リポタンパク質分布パターンは、統計学的に異なるという事を見出した。したがって、Gll-6はそれらの疾患の鑑別、病態把握や治療法評価に新知見を与える可能性が示された。
本研究テーマのこれまでの進捗と結果を総括すると、ヒト血液中に存在するTG-rich LDLを認識するモノクローナル抗体Gll-6を得て、穏やかに酸化されたリポタンパク質を簡便に測定するELISAを構築することができた。
Gll-6ELISAは、健常者のsd LDLや高TG血症患者の酸化レムナントの検出、さらには、肝疾患患者の重症度評価や、NASH患者の異常リポタンパク質の検出に貢献できる可能性が示された。
