Abstract

The expression of human hepatitis B virus (HBV) surface (HBS) and e (HBe) antigens has been studied comparatively in monkey and mouse cell lines co-transfected with HBV DNA and the dominant selective marker aminoglycoside 3'-phosphotransferase gene. We have found that the kinetics and stability of expression of the HBS gene varies with the cell lines used. Only a late transient expression of both HBS and HBe is observed between 1 and 5 weeks after transfection in monkey kidney Vero cells transfected with the complete HBV genome, while a permanent expression of HBS and HBe is obtained in mouse cells. HBS and HBe are excreted into the cell culture medium. HBe is expressed in cells transfected with the complete HBV genome, but not with isolated HBS gene. In clones of Vero cells transformed with the HBS gene, HBV sequences were rearranged or lost.
