DMTU and NAC added after cisplatin treatment suppresses p53 activation and apoptosis in renal tubular cells. RPTC cells were incubated with 20 µM cisplatin for 2 h. Then cisplatin was removed for further 22 h of incubation in the presence or absence of 5 mM DMTU or 0.5 mM NAC. (A) %Apoptosis. (B) Caspase activity. Data are expressed as means ± S.D. (n = 6). *Statistically significantly different from the control group; #significantly different from the cisplatin-only group. (C) Representative blots for p53 and phospho-p53. Whole cell lysates were examined by immunoblot analysis.
