| 内容記述 | The molecular mechanisms underlying the progression of nonalcoholic steatohepatitis (NASH) have not been fully elucidated. The aim of this study was to identify factors involved in NASH progression by analysis of pathophysiological features and gene-expression profiles in livers of STAM mice, a model of NASH-associated hepatocarcinogenesis. C57BL/6N (B6N) mice were injected with streptozotocin to generate STAM mice. Four-week-old male STAM and B6N mice were fed a high-fat diet (HFD) (STAM-F, B6N-F) or a conventional diet (STAM-C, B6N-C) until they were 10, 14, or 18 weeks old. Blood glucose and nonalcoholic fatty liver disease (NAFLD) activity scores of STAM-F were higher than those of STAM-C during all observation periods. STAM-F mice had more severe hepatic fibrosis at 14 weeks, and exhibited higher levels of α-fetoprotein-positive hepatic tumor formation with multiplication than STAM-C mice at 18 weeks. At 14 weeks, cDNA microarray analysis revealed that the hepatic expression of eight mRNAs was ≥30-fold higher in STAM-F than B6N-F mice. The expression of another four genes was increased ≥5-fold in STAM-F than B6N-F mice, and ≥5-fold in B6N-F relative to B6N-C mice. Of the 12 genes, the difference in Sptlc3 mRNA expression was most pronounced, and gradually increased over time, as determined by quantitative RT-PCR in STAM-F mice. In addition, Sptlc3 mRNA expression in STAM-F mice was higher than that in db/db micethat received HFD and in B6N mice fed a choline‑deficient L-amino acid (CDAA)-defined diet. In conclusion, a high-fat diet aggravated pathophysiological findings in the liver in NASH mouse models, and the hepatic expression of Sptlc3 mRNA was potentially associated with NASH progression.
