The Nrf2-Keap1-ARE pathway is an important signaling axis that functions to protect cells against oxidative stress and harmful chemicals through the induction of cytoprotective genes. The maintenance and protective role of Nrf2 pathway has been recognized as a means for chemoprevention. On the other hand, constitutive activation of Nrf2, due to somatic mutations of genes that control Nrf2 degradation, promotes carcinogenesis and imparts chemoresistance to cancer cells. Autophagy is another tightly regulated...
