Abstract excerpt
Mutational inactivation of the tumor suppressor gene p53 is common in hepatocellular carcinomas (HCC). AGG to AGT transversion in codon 249 of exon 7 of the p53 gene occurs in over 50% of HCC from endemic regions, where both chronic infection with the hepatitis B virus (HBV) and exposure to carcinogens such as aflatoxin B1 (AFB1) prevail. In this study, we report the effect of the HBV x protein (HBx) on...
