Mitophagy Impairment Aggravates Cisplatin-Induced Ototoxicity

Figure 4

Knockdown of Parkin and BNIP3 enhances cisplatin- (CP-) induced mitochondrial dysfunction. HEI-OC1 cells were transfected with the indicated siRNAs followed by treatment with cisplatin (10 μM, 24 h). (a) Mitochondrial membrane potential was examined by flow cytometry. (b) Mitochondrial depolarization was significantly greater in cisplatin-treated HEI-OC1 cells transfected with Parkin and BNIP3 siRNAs as compared to cisplatin-treated cells transfected with si-Control. (c) Knockdown of Parkin and BNIP3 impairs the cisplatin-induced reduction of intracellular ATP. Data are presented as the of five independent experiments. .
