Moderate alcohol consumption diminishes the development of non-alcoholic fatty liver disease (NAFLD)

Using ob/ob mice as a model of non-alcoholic fatty liver disease (NAFLD), researchers investigated the effect of moderate alcohol intake on the development of NAFLD and molecular mechanisms involved. The Ob/ob mice were fed water or ethanol solution (2.5 g/kg body weight/day) for 6 weeks, and markers of liver injury, insulin signalling and adiponectin in visceral adipose tissue were determined.

Whereas bodyweight and the degree of liver steatosis did not differ among ob/ob mouse groups, those consuming ethanol had markedly less macrovesicular hepatic fat accumulation, inflammatory alterations and significantly lower transaminase levels. Despite similarly elevated protein levels of tumour necrosis factor , protein concentrations of plasminogen activator inhibitor 1 were significantly lower in livers of ob/ob mice consuming ethanol in comparison with controls. The hepato-protective property of moderate alcohol ingestion in ob/ob mice was associated with an induction of the sirtuin-1/adiponectin-signalling cascade in visceral fat tissue and an activation of Akt in the liver. Similar effects of moderate alcohol exposure were also found in vitro in 3T3-L1 and AML- 12 cells.

These data suggest that moderate alcohol intake may diminish the development of NAFLD through sirtuin- 1/-adiponectin-dependent signalling cascades.
