Project description:Patients with diabetes mellitus (DM) have an epidemiologically higher risk for hepatocellular carcinoma (HCC). In mouse models, administration of streptozotocin (STZ) induces insulin-dependent DM by causing islet beta-cell dysfunction and also induced hepatocellular carcinoma (HCC) after 12 weeks. We attempted to elucidate the carcinogenic mechanism in the precancerous state by using hepatic miRNAs and create precancerous marker using exosomal miRNA. Serum and liver tissues were collected from STZ mice and non-treated mice (CTL mice) at 6, 10 and 12W. Total RNA in liver and exosome were extracted. Histological examination in liver in HE stain and hepatic and exosomal miRNA analysis were serially performed. miRNA and mRNA was analyzed by next-generation sequencing (NGS). The raw data of NGS was analyzed by Principal Component analysis. No inflammation or fibrosis was found in the liver in CTL mice during the observation period. In STZ-treated mice, regeneration and inflammation of hepatocytes was found at 6W and then nodules of atypical hepatocytes were found at 10 and 12 W. Expression of let-7f-5p, miR-21a-5p, 22-3p, and 26a-5p in liver of STZ mice was significantly increased during 6-10W, and these miRNAs controlled several tumor suppressor genes as target genes. We also identified six novel miRNAs associated with precancerous status. Furthermore, miR-122-5p and miR-192-5p in exosome were significantly upregulated in STZ mice in precancerous state. The expression of miRNAs that regulate tumor suppressor genes was enhanced even before carcinogenesis, and the expression of these miRNAs was not affected by liver fibrosis. In addition, the expression pattern of miRNAs in exosome is expected to be a marker for predicting carcinogenesis.

Project description:Streptozotocin administration to mice (STZ-mice) induces type I diabetes and hepatocellular carcinoma (HCC). We attempted to elucidate the carcinogenic mechanism and the miRNA expression status in the liver and blood during the precancerous state. Serum and liver tissues were collected from STZ-mice and non-treated mice (CTL-mice) at 6, 10, and 12 W. The exosome enriched fraction extracted from serum was used. Hepatic histological examination and hepatic and exosomal miRNA expression analysis were serially performed using next-generation sequencing (NGS). Human miRNA expression analysis of chronic hepatitis liver tissue and exosomes, which were collected before starting the antiviral treatment, were also performed. No inflammation or fibrosis was found in the liver of CTL-mice during the observation period. In STZ-mice, regeneration and inflammation of hepatocytes was found at 6 W and nodules of atypical hepatocytes were found at 10 and 12 W. In the liver tissue, during 6-12 W, the expression levels of let-7f-5p, miR-143-3p, 148a-3p, 191-5p, 192-5p, 21a-5p, 22-3p, 26a-5p, and 92a-3p was significantly increased in STZ-mice, and anti-oncogenes of their target gene candidates were down-regulated. miR-122-5p was also significantly down-regulated in STZ-mice. Fifteen exosomal miRNAs were upregulated in STZ-mice. Six miRNAs (let-7f-5p, miR-10b-5p, 143-3p, 191-5p, 21a-5p, and 26a-5p) were upregulated, similarly to human HCC cases. From the precancerous state, aberrant expression of hepatic miRNAs has already occurred, and then, it can promote carcinogenesis. In exosomes, the expression pattern of common miRNAs between mice and humans before carcinogenesis was observed and can be expected to be developed as a cancer predictive marker.

Project description:Liver fibrosis, results from the imbalance between extracellular matrix (ECM) production and degradation, is a common pathological consequence of various chronic liver diseases. Although a large number of miRNAs have been reported in liver fibrosis progression, miRNA-mRNA interactions involved in its reversal process remain to be fully elucidated. In the current study, we performed an integrated analysis of miRNA and mRNA expression profiles in a hepatic fibrosis recovery mouse model induced by thioacetamide. A total of 102 miRNA and 2,845 mRNAs showed significant differential expression in recovery mice compared to fibrotic mice. Moreover, 3,769 putative negatively correlated miRNA-mRNA pairs were revealed to be potentially implicated in the biological function regulation of small molecule metabolism and ECM organization. By integrating miRNA-mRNA regulatory networks, mmu-miR-1843a-5p, mmu-miR-193a-5p, mmu-miR-194-2-3p and mmu-miR-30c-2-3p were identified as lysyl oxidase-specific miRNAs that were associated with the pathogenesis of fibrosis recovery. Our results provide potential novel biomarkers and candidate targets for the treatment of liver fibrosis.
