Effect of p53 gene polymorphism on functions of prostate cancer cells
Prostate cancer cells were transfected with plasmids [empty plasmids, wild-type pcDNA3.1-p53 (V/V), mutant type pcDNA3.1- p53 (G/G)] to analyze the effect of p53 gene polymorphisms on the proliferation, cycle, and apoptosis of prostatic cancer cells. Empty plasmids containing wild-type pcDNA3.1-p53 (V/V) and mutant type pcDNA3.1- p53 (G/G) were used to transfect PC3 and LNCaP cells, respectively. Cell proliferation was detected at 0, 24, 48, and 72 h using the MTT method. Cells were collected at 24 and 72 h.
