Transcription factor may protect against hepatic injury caused by hepatitis C and alcohol
Date:11/10/2013

icology, and Therapeutics, also report that FOXO3 protects against acute ethanol-induced steatosis and liver injury. This study demonstrates that FOXO3 is necessary for activation of autophagy, a cellular degradation pathway that protects against alcohol-induced liver injury by removing damaged mitochondria. Acute alcohol-treated FOXO3-deficient mice developed more severe liver injury than that of wild-type mice, and this was attributed to decreased expression of autophagy-related genes.

"Our study," says Dr. Ding, "was an acute alcohol model whereas the study in Dr. Weinman's laboratory was a chronic alcohol feeding model; however, both studies show that FOXO3 is protective. Thus, these results indicate that FOXO3 is an important general mechanism by activating multiple cellular protective functions that the normal liver uses to resist the toxic effects of alcohol."
