Outline of Final Research Achievements

NRF2 is a master transcriptional activator playing a critical role in the defense mechanism against oxidative insults. NRF2 activates genes encoding cytoprotective enzymes and antioxidant proteins in response to electrophiles and reactive oxygen species (ROS), conferring resistance against xenobiotic and oxidative stress. While NRF2 activation is beneficial to our health, NRF2 is responsible for the malignant progression of various human cancers. To develop a new anti-cancer therapy for NRF2-addicted malignant cancers, we examined molecular mechanisms how NRF2 activation influences on the cancer evasion from the anti-cancer immunity. We found that NRF2 in cancer cells reduces expression of MHC class I and other genes involved in the antigen presentation, suggesting that NRF2 promotes the cancer evasion from the anti-cancer immunity.
