ROS-dependent Nrf2 regulation further varies across microenvironments: APE1 mediates ROS-dependent Nrf2 activation in Barrett’s esophageal adenocarcinoma [83], whereas autophagy-related proteins (e.g., SQSTM1/p62) regulate this axis in HCC [84]. This evidence concerns the gene SQSTM1 and hepatocellular carcinoma.
