The Epstein–Barr virus (EBV) is an oncogenic Herpes virus involved in the induction of a variety of human tumours. It was the first virus found to encode microRNAs (miRNAs). MiRNAs are short, non-coding RNAs that in most cases negatively regulate gene expression at the post-transcriptional level. EBV-transformed cells express at least 44 mature viral miRNAs that target viral and cellular genes. In...
The X protein (HBx) of hepatitis B virus (HBV) plays important roles in hepatitis, cirrhosis, and hepatocellular carcinoma (HCC) during viral infection. In this study, we demonstrated that co-transfection of mouse embryo fibroblasts (STO) with HBx and activated Ras triggered apoptotic cell death, while HBx or activated Ras individually failed to induce apoptosis. In addition, STO cells were able to...
