Abstract:
Objective: This study was designed to explore the significance and the role of wild-type p53 (wt-p53) gene and mutant p53 gene(mt-p53) transfer on human glandular lung cancer cell growth in nude mice. Methods: wt-p53 gene and mt-p53 gene were transfected and lipofectin-mediated into the human glandular lung cancer cell line GLC-82. And the growth of gene-transfected cell lines were observed in vitro and in vivo. Results: The colony number in the colong-forming experiment and the volume and weight in nude mice were greater in the mf-p53 tranfecting cells group than in the control group. The tumor resulting from the cells transfected with the wt-p53 gene grew more slowly and was smaller than that from control GLC-82 cells. In contrast, the tumor from the cells transfected with the mt-p53 gene grew faster than that produced by cells transfeted with the wt-p53 gene and that produced by control GLC-82 cells. Conclusion: The wild-type p53 gene could inhibit the glandular lung cancer cell growth in nude mice and the mutant p53 gene could enhance the glandular lung cancer cell growth in nude mice.
