Abstract:
Objective:To explore the effects of wild type p53 gene on biologic behavior of human ovarian cancer cell line SKOV 3 and the efficacy of cisplatin against the cancer cells when combined with p53 gene therapy.Methods:A human wild type p53 gene recombinant eukaryotic expression vector was introduced by lipofectin mediated gene transfection into SKOV 3 cells which does not express endogenous p53.The clones obtained were observed for their biological behavior and the colony formation when exposed to cisplatin.Results:The exogenous wild type p53 gene expressed stably in the cells.The growth rate and colony formation of these transfected cells were suppressed significantly by exogenous p53 gene and the percentage of phase G 1 cells increased.There was an increasement in the sensitivity to cisplatin of the transfected cells.Conclusion:Exogenous wild type p53 gene can suppress the growth of human ovarian cancer cells and increase the efficacy of cisplatin against the cells.
