Prohibitin Is a Novel Regulator of Antioxidant Response That Attenuates Colonic Inflammation in Mice

These results show that PHB is a regulator of Nrf2 expression in intestinal epithelial cells during oxidative conditions and prevents inflammation-associated oxidative stress and injury through sustained activation of Nrf2. Our data show that PHB is a novel regulator of antioxidants and suggest that restoration of PHB levels represents a potential therapeutic approach in inflammatory bowel disease.
