Depletion of p53 by RNAi prolongs cell survival following cisplatin treatment. (A and B) p53 siRNA or control siRNA was transfected into WT Bcl2-expressing H7 cells using Lipofectamine 2000. Cells were treated with cisplatin (10 μM) for 72 h, and the levels of p53 expression were analyzed by Western blotting using a p53 antibody. Cell viability was assessed as described in the legend for Fig. 1C. Data represent the mean ± standard deviation of three separate experiments.
