Project description:Hepatitis B virus (HBV) infection is one of the major causes of hepatocellular carcinoma (HCC). Nucleos(t)ide analogue (NA) therapy is effective to reduce the HCC incidence, while it doesn’t completely prevent HCC. In this study, we explored the involvement of microRNA (miRNA) in the post-NA treatment HCC development. Chronic hepatitis B (CHB) patients who received NA treatment (n = 18) were divided into 2 groups: those who didn’t develop HCC during the follow-up period (non-HCC group) and those who developed HCC after treatment (HCC group). Liver specimens were obtained before and after NA therapy, and HCC tissues were also obtained from the HCC group patients. Normal liver tissues were also obtained from 4 liver hemangioma patients who underwent surgical resection. miRNA expression was analyzed using Agilent miRNA microarray V3.
Project description:The emergence of drug-resistant viruses against nucleot(s)ide analogs (NAs), which are the main treatment for chronic hepatitis B virus (HBV) infection, has become a problem. To discover novel anti-HBV compounds with a low risk of emergence of drug-resistant viruses, we performed screening of a G protein-coupled receptor-associated compound library and identified Rimonabant as a candidate. Transcriptome analysis of Rimonabant-treated primary hepatocytes by RNA sequencing revealed that the transcriptional activity of HNF4α, which is known to stimulate viral RNA synthesis, was depressed.
