Abstract:
Objective To investigate the suppression effects of tumor suppressor gene p53 alone and apoptosis incombination with TNF-? in a hepatocellular carcinoma cell line Hep3B. Methods Hep3B cells were transfected with a wild-type p53 cDNA(wt-p53)and plain vector(pNeo) respectively. Then the cell were cultured for 12 hours, one of the transfected p53 groups was added TNF-?(20 ?g/ml). The expression of p53 was detected by immunological fluorescence assay. Determination of apoptosis was used by DNA fragmentation, TUNEL assay. Results Both a small dose TNF-? and wt-p53 can induce apoptosis more efficiently comparing with non-transfected cultures(P
