Abstract:
To observe the expression of human wild-type p53, B7-1 and GM-CSF genes mediated by recom-binant adenovirus and their effects of inducing apoptosis on lung cancer cells. Methods; Human wild-type p53, B7-1 and GM-CSF genes were transfected into lung cancer cells mediated by recombinant adenovirus. The expression products of these genes were detected by immunohistochemistry assay, flow cytometric analysis and ELISA. Cell growth assay was carried out by counting alive cells after trypan blue exclusion. Cell apoptosis was detected by TdT assay of DNA fragmentation . Results: The multi-genes could be efficiently expressed in lung cancer cells mediated by recombinant adenovirus, which could suppress lung cancer cell growth and induce their apoptosis. Conclusion: These results suggest the feasibility of muti-gene therapy for lung cancer.
