DDP suppressed A549/DDP and A549 cells proliferation. The lung cancer cells were stimulated by various concentrations of DDP for 48 hours, and the A549/DDP and A549 cells proliferation suppression rates were determined by MTT assay. (A) The inhibitory effect of DDP on A549/DDP and A549 cell growth. (B) IC50 value of DDP. The results were shown as means±SD. * P<0.05, and ** P<0.01 compared to A549 cells. DDP – cis-diamminedichloroplatinum also known as cisplatin; MTT – thiazolyl blue tetrazolium bromide; SD – standard deviation.
