Objective:To research the expression of apoptosis-related oncogenes of wptp53 on the growth of human lung cancer line A549 . Methods: To study the effects of APS on the expression of wptp53 mRNA in the human lung cancer cell line A549 by RT-PCR. Results: APS could increase the expression of p53 gene significantly when concent ration of APS was 6.25μg/ml, 12.50μg/ml, 25.00μg/ml (P<0.05 or P<0.01) .Conclusion: APS could obviously enhance the expression of p53 tumor suppressor gene, its anti-tumor effect may a...
