LC3 II protein expression levels of cisplatin-resistant A549 cells (a) and cisplatin-sensitive A549 cells (b). The concentrations of DDP in a, b were 60 and 25 µM, respectively. The concentrations of TET was 0.25 µg/ml. The time of the drug treatments was 12 h. c, d are the statistical analyses of a, e and f are the statistical analyses of b. *p < 0.05 versus the control cells, ^#represents p < 0.05 versus the DDP treatment (n = 3)
