Hepatitis B virus surface antigen (HBsAg) could be studied until recently only by isolating it from the blood of carriers, thus making incorporation of radioactive precursors into this protein(s) impossible. The isolation of a cell line producing HBsAg [Alexander et al, 1978] has eliminated this obs

โฆ Synopsis
Three drugs were assayed for their capacity to inhibit hepatitis B surface antigen (HBsAg) production by the PLC/PRF/5 human hepatoma cell line. The effect on cell growth and HBsAg production of Cordycepin, 6-azauridine, and Hygromicin B is reported. Hygromicin B, a translation inhibitor unable to penetrate normal cells, greatly reduced HBsAg production by growing and confluent cells.

The human hepatoblastoma-derived cell line HB6 I I secretes hepatitis-B surface antigen (HBsAg) and hepatitis-B e antigen (HBeAg) into the medium. Hepatitis-B-virus(HBV) DNA integrated into the cellular genome was found to be hypermethylated. When the cells were treated with 5-azacytidine for 3 days
Previously, we have found that human liver annexin V (hA-V; in earlier reports referred as Endonexin II) is a specific hepatitis B surface antigen (HBsAg) binding protein. In this study, we demonstrate that transfection of rat hepatoma FTO 2B cells, a cell line that is not infectable by hepatitis B
It has been postulated that tumor cells expressing Fas ligand (FasL) can evade immune surveillance by inducing apoptosis in T cells expressing Fas. In this study, we investigated FasL expression in 13 human hepatoma cell lines. Strong FasL expression was detected by reverse transcriptionpolymerase c
