MicroRNA-34c targets TGFB-induced factor homeobox 2, represses cell proliferation and induces apoptosis in hepatitis B virus-related hepatocellular carcinoma.

MicroRNAs (miRs) are short, non-coding RNAs with post-transcriptional regulatory functions. Previous studies have demonstrated that miR-34c is involved in diverse biological processes, including carcinogenesis. The aim of the present study was to investigate the role of miR-34c and its target genes in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC).

miR-29c targets TNFAIP3, inhibits cell proliferation and induces apoptosis in hepatitis B virus-related hepatocellular carcinoma.

Recent studies have revealed that microRNA-29c (miR-29c) is involved in a variety of biological processes including carcinogenesis. Here, we report that miR-29c was significantly downregulated in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) cell lines as well as in clinical tissues compared with their corresponding controls. Tumor necrosis factor alpha-induced protein 3 (TNFAIP3), a key regulator in inflammation and immunity, was found to be inversely correlated with miR-29c levels and was identified as a target of miR-29c.

miR-122 inhibits viral replication and cell proliferation in hepatitis B virus-related hepatocellular carcinoma and targets NDRG3.

microRNAs (miRNAs) are short, non-coding RNAs with post-transcriptional regulatory functions that participate in diverse biological pathways. miR-122, a liver-specific miRNA, has been found to be down-regulated in hepatocellular carcinoma (HCC) and HCC-derived cell lines. In this study, miR-122 was down-regulated in the hepatitis B virus (HBV)-related HCC cell line HepG2.
