C‐terminal truncated hepatitis B virus x protein is associated with metastasis and enhances invasiveness by c‐jun/matrix metalloproteinase protein 10 activation in hepatocellular carcinoma
Karen M.F. Sze, Glanice K.Y. Chu, Joyce M.F. Lee, Irene O.L. Ng – 23 July 2012 – Random integration of hepatitis B virus (HBV) DNA into the host genome is frequent in human hepatocellular carcinoma (HCC) and this leads to truncation of the HBV DNA, particularly at the C‐terminal end of the HBV X protein (HBx). In this study, we investigated the frequency of this natural C‐terminal truncation of HBx in human HCCs and its functional significance. In 50 HBV‐positive patients with HCC, full‐length HBx was detected in all nontumorous livers.
