PLC/PRF/5 cell [32P]RNA was found to hybridize with all restriction fragments of HBV DNA adequately tested, indicating that at least most, and possibly all, of the viral DNA in these cells is transcribed.
Hepatitis B core antigen and its antibody and hepatitis B e antigen and its antibody were not detected in 26 mice, using immunohistochemical and radioimmunoassay methods. alpha-Fetoprotein, carcinoembryonic antigen, and alpha-antitrypsin were detected in nude mice tumors, using the peroxidase-antiperoxidase technique.
Finally, hepatitis B virus DNA, identified in the nude mouse tumor by molecular hybridization techniques, was compared to PLC/PRF/5 cell line hepatitis B virus DNA.
320 adults and children of an isolated community of Bali, Indonesia, have been tested for blood groups ABO, Rh, MNS, P, Lewis, Duffy, Kell, for haptoglobin and transferrin and for hepatitis B surface antigen and antibodies.
The rearrangements of chromosome I are most striking in the Hep 3B and PLC/PRF/5 cell lines, which are derived from human hepatocellular carcinomas and contain integrated copies of the hepatitis B viral genome.

The temporal relation between the cytopathologic response and HBc gene expression was similar for both cell types, indicating a primary role for HBc gene expression in the cytopathology of HBV-infected human liver.
A group of people judged to be at high risk of PHC because of long-term serological positivity for hepatitis B surface antigen, ethnicity, location of residence, and a strong family history of PHC were screened for increasing levels of AFP.
We report here the isolation by molecular cloning and the analysis by heteroduplex and restriction enzyme mapping of seven distinct DNA fragments containing hepatitis B virus (HBV) sequences from genomic DNA of the PLC/PRF/5 human liver carcinoma cell line (the Alexander cell).
Colonies of tk-transformed cells, selected after 3-4 weeks of incubation and subcultured in HAT medium, synthesized either hepatitis B surface antigen (HBsAg) alone or HBsAg in combination with hepatitis B e antigen (HBeAg).
The human PLC/PRF/5 hepatoma cell line (the Alexander cell) contains at least seven copies of hepatitis B virus (HBV) DNA integrated in its genome; but it selectively expresses the HBV surface antigen (HBsAg) gene and perhaps low levels of the core gene.
In vitro and in vivo synthesis of the hepatitis B virus surface antigen and of the receptor for polymerized human serum albumin from recombinant human adenoviruses.
The karyotype of the PLC/PRF/5 (Alexander) human hepatoma cell line was identified at passage +/- 110, prior to attempting in situ hybridization studies to determine the chromosomal localization of the hepatitis B virus (HBV) DNA integration sites.
In situ hybridization of an HBV DNA probe to metaphase chromosomes of the PLC/PRF/5 cell line, followed by statistical analysis, identified three integration sites; these were 15q22-q23, 11q22, and 18q12.
