Additive activation of hepatic NF-kappaB by ethanol and hepatitis B protein X (HBX) or HCV core protein: involvement of TNF-alpha receptor 1-independent and -dependent mechanisms.

Abstract excerpt

Alcohol consumption and viral hepatitis infection synergistically accelerate liver injury, but the underlying mechanism is not fully understood. Here we have examined the effects of ethanol on hepatitis B protein X (HBX)- or hepatitis C core protein (HCV core protein)-mediated activation of NF-kappaB, a critical signal in hepatic injury, regeneration, and tumor transformation. Acute ethanol or acetaldehyde...
