Abstract

AIM: To investigate the therapeutic effect of TNF gene transfected LAK cells on ascitic liver carcinoma bearing mice.

METHODS: TNF gene was transfected into murine LAK cells by retrovirus. Low dose TNF gene transfected LAK cells and IL-2 were i.p. injected into murine model. Cytotoxicity of gene transfected LAK cells was studied in vitro growth and the survival time of murine model was observed.

RESULTS: TNF gene-transfected LAK cells secreted higher level of TNF than that of normal LAK cells or control gene-transfected LAK cells. The in vitro growth ability and cytotoxicity of TNF gene-transfected LAK cells were markedly inhibited by anti-TNF monoclonal antibodies. Significant therapeutic effect on ascitic liver carcinoma bearing mice was achieved.

CONCLUSION: TNF gene transfected LAK cells have therapeutic effect on ascitic liver carcinoma bearing mice.
