title: [Hepatitis B virus and hepatoma: evidence for a cytoplasmic tumor antigen in transformed hepatocytes].
abstract: A tumoural antigen (HBV/T Ag) has been found in the cytoplasm of the human hepatoma cell line PLC/PRF/5 by indirect immunofluorescence and immunoperoxidase assays using anti-sera from Senegalese patients with primary hepatocellular carcinoma. The same antigen was detected in PHC tissues. According to the data obtained with serum and tissue controls the HBV/T Ag-anti-HBV/T system seems associated with transformation of hepatocytes by hepatitis B virus.
