dc.description.abstractCarbonyl cyanide m-chlorophenyl hydrazone (CCCP) is a mitochondrial depolarizing agent that induces reactive oxygen species (ROS)-mediated cell death. The Nrf2-Keap1 pathway is crucial for the elimination of ROS in stressed cells. However, the molecular mechanism underlying the regulation of the Nrf2-Keap1 pathway in CCCP-induced cell death is unknown. In this study, we demonstrated that CCCP promotes Keap1 degradation, and thereby activates Nrf2. This CCCP-mediated Keap1 degradation is partly dependent on autophagy. Moreover, CCCP-induced Keap1 degradation is mainly reliant on p62, which functions as an adaptor protein during selective autophagy. Lack of p62 blocked CCCP-induced Keap1 degradation and inhibited Nrf2 activation, and thereby increased the accumulation of ROS. Ablation of p62 increased the susceptibility of cells to oxidative stress. These results indicate that p62 plays an important role in protecting cells against oxidative stress through Keap1 degradation-mediated Nrf2 activation.-
