Activation of NADPH Oxidase 4 in the Endoplasmic Reticulum Promotes Cardiomyocyte Autophagy and Survival During Energy Stress Through the Protein Kinase RNA-Activated-Like Endoplasmic Reticulum Kinase/Eukaryotic Initiation Factor 2α/Activating Transcription Factor 4 Pathway

Abstract

Nox4 critically mediates autophagy in response to energy stress in cardiomyocytes by eliciting ROS in the ER and stimulating the protein kinase RNA-activated-like ER kinase signaling pathway.
