Abstract
A rat hepatocellular carcinoma cell line (cKDH-8 cl-11) showed decreased tumorigenicity after transfection with an envelope gene derived from a Friend leukemia virus (FV-env gene). FV-env gene product was found by indirect immunofluorescence staining to be expressed on the cell surface of the FV-env gene-transfected cells. The FV-env-transfected cells (FV-env cKDH-8), however, grew well in X-irradiated immunosuppressed rats, indicating that the reduction in tumorigenicity of the transfected cells is based on immunological reaction in the host. The rats which rejected FV-env cKDH-8 cells showed resistance to rechallenge with the parent cKDH-8 cl-11 tumor cells. These results suggest that the FV-env gene product may elicit antitumor immunity against FV-env cKDH-8 cells in a host with a resultant reduction in the tumorigenicity of these cells.Entities:
