Project description:Background: The pathogenesis of hepatitis B virus (HBV)-caused hepatocellular carcinoma (HCC) is complex and not fully understood. In clinical, the effective prevention and treatment of HCC rely on the accurate diagnosis. We developed a biology network approach to investigate the potential mechanisms and biomarkers of each stages from HBV infection to HCC. Methods Global gene profiling of healthy individuals (HC), HBV carriers (HBVC), chronic hepatitis B patients (CHB), liver cirrhosis (LC) and HCC was analyzed by gene array. Differentially expressed genes (DEG) were found by RVM (Random variance model) corrective ANOVA and STC (Series Test of Cluster) analysis.

Project description:Genome-wide DNA methylation profiling was performed in peripheral leukocytes to identify biomarkers that could track hepatitis B progression to hepatocellular carcinoma (HCC). Samples included 48 HBsAg carriers who developed HCC and 48 HBsAg carriers who did not during follow-up.

Project description:We applied small RNA Solexa sequencing technology to identify microRNA expression in human liver samples from surgically removed liver tissues including three normal liver tissues (distal normal liver tissue of liver hemangioma), an hepatitis B virus (HBV)-infected liver, a severe chronic hepatitis B liver, two HBV-related hepatocellular carcinoma (HCC), an hepatitis C virus (HCV)-related HCC, and an HCC without HBV or HCV infection. All samples were collected with the informed consent of the patients and the experiments were approved by the ethics committee of Second Military Medical University, Shanghai, China. We investigated the miRNome in human normal liver and suggested some deregulated abundantly expressed microRNAs in HCC. center_name: National Key Laboratory of Medical Immunology & Institute of Immunology, Second Military Medical University, Shanghai, China. Examination of miRNome in human liver samples from surgically removed liver tissues including three normal liver tissues (distal normal liver tissue of liver hemangioma), an hepatitis B virus (HBV)-infected liver tissue, a severe chronic hepatitis B liver tissue, an HBV-related hepatocellular carcinoma (HCC) tissue and adjacent liver tissues of different regions,an HBV-related HCC tissue and adjacent liver tissue, an hepatitis C virus (HCV)-related HCC tissue and adjacent liver tissue, and an HCC without HBV or HCV infection and adjacent liver tissue. All 15 human liver tissue samples.

Project description:Small, non-coding RNAs control gene expression post-transcriptionally and play important roles in virus-host interactions. Within the liver, the microRNA (miRNA) miR-122 is essential for replication of hepatitis C virus (HCV), while repression of miR-148a by hepatitis B virus (HBV) may enhance tumorigenesis. Despite their importance to the outcome of these infections, few previous studies have described unbiased profiling of small RNAs in the liver during chronic viral hepatitis. Here, we sequenced small (14-40 nts) RNAs in liver from subjects with chronic hepatitis B and C. We found that small RNAs derived from tRNAs, specifically 5’ tRNA-halves (“5’ tRHs”, ~31-34 nts), are abundant in liver and significantly increased during chronic viral infection in humans and also chimpanzees. In most infected livers, 5’ tRH abundance exceeded that of miRNAs. In contrast, in hepatocellular carcinoma (HCC) tissue from these subjects, tRH abundance was reduced concomitant with decreased expression of the tRNA-cleaving ribonuclease, angiogenin. Although tRHs have been identified in mice, our results show they are abundantly expressed in human tissue, increased in chronic viral infection, and decreased in liver cancer. Our findings highlight the potential biological and clinical relevance of these small non-coding RNAs. Small RNA-seq of liver samples from control subjects (n=4), subjects with chronic hepatitis B (n=4) and hepatitis B associated hepatocellular carcinoma (n=4, 3 out of 4 matched with non-tumor tissue) and subjects with chronic hepatitis C (n=4) and tissue from hepatocellular carcinoma of the same patients. Also, small RNA-seq of AGO2 and IgG pulldown in FT3-7 cells. Sequenced AGO2 pulldown (n=3), IgG pulldown (n=2) and total small RNA from FT3-7 cells (n=3).
