The expression of proliferation- and apoptosis-related proteins of the cells in response to different treatments for 12 h. a Proteins expression of cisplatin-resistant A549 cells after each drug treatment. The concentrations of DDP and TET were 60 µM and 0.25 µg/ml, respectively. b Proteins expression of cisplatin- sensitive A549 cells. The concentrations of DDP and TET were 25 µM and 0.25 µg/ml, respectively. c–e are the statistical analyses of a, besides, f–h are the statistical analyses of b. *p < 0.05 versus the control cells, ^#p < 0.05 versus the DDP treatment (n = 3)
