Mitophagy Impairment Aggravates Cisplatin-Induced Ototoxicity

Figure 5

Chemical inhibition of cisplatin (CP) augmented mitophagy induces cytotoxicity and suppresses the expression of mitophagy-associated proteins. (a) The survival of cisplatin-treated HEI-OC1 cells was significantly reduced by pretreatment with the mitophagy suppressor 3-MA. (b, c) Pretreatment with 3-MA downregulates the expression of PINK1, Parkin, BNIP3, and LC3B in a dose-dependent manner. Data are presented as the of five independent experiments. 3-MA: 3-methyladenine; .
