Research Abstract

Pathogenesis by disrupting the cytoprotective system
Keap1-Nrf2 system regulates a battery of cytoprotective genes in response to both endogenous and exogenous stimuli. Constitutive Nrf2 activation by Keap1 deletion leads to hyperkeratosis in the upper digestive tract. In this study, we examined impaired autophagy activates Nrf2 to cause liver injury. The results indicate that Nrf2 activation needs properly regulation by Keap1.
