Influence of each treatment on cell proliferation. a EDU staining of cisplatin-resistant A549 cells after various treatments (×200). The concentrations of DDP and TET were 60 µM and 0.25 µg/ml, respectively. b EDU staining of cisplatin-sensitive A549 cells (×200). The concentrations of DDP and TET were 25 µM and 0.25 µg/ml, respectively. The time of the drug treatments was 12 h. c, d are the statistical analyses of a, b. *p < 0.05 versus the control cells; ^#p < 0.05 versus DDP treatment (n = 3)
