Hepatic oval cells (HOC) are considered to be the stem cells of the liver and have been linked to the development of hepatic malignancies. Studies have demonstrated that chronic hepatitis B virus (HBV) infection and dietary aflatoxin B1 (AFB1) exposure are among the most important risk factors for the development of hepatocellular carcinoma (HCC). However,(More)
Growing evidence has shown that hepatic oval cells, also named liver progenitor cells, play an important role in the process of liver regeneration in various liver diseases. Oval cell proliferation has been reported in hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) and chronic liver disease. Studies have found expression of HBV surface(More)
OBJECTIVE To construct pEGFP-HBx eukaryotic expression plasmid and establish stable and effective transfected rat oval cell (LE/6) strain expressing EGFP-HBx fusion protein to explore the roles of HBx gene and oval cell in carcinogenesis of hepatocellular carcinoma (HCC). METHODS HBx gene with EcoRI and Hind III endo-enzyme sites was obtained by using PCR(More)
OBJECTIVE To determine whether hepatitis B virus X (HBX) protein expression affect the oval cells' response to anti-proliferative effect of transforming growth factor β1 (TGFβ1) in oval cells. METHODS Real-time PCR, Western blot analysis were performed to detect the expression of TGFβRII in HBX-transfected oval cells named HBX-EGFP-LE/6, and EGFP-LE/6,(More)
