Folic acid supplementation ameliorates alcohol-induced hepatic steatosis by inhibiting SREBP-1c-mediated lipogenesis.

ABSTRACT:

Background

Alcoholic fatty liver disease (AFLD), a prevalent yet reversible stage of alcoholic liver pathology, is often associated with folate deficiency. This study investigated the association between folate status and AFLD risk and explored the underlying mechanisms.

Methods

Data from NHANES 2011-2020 (n = 10,452; 259 with AFLD) were analyzed. Associations between dietary folate equivalent (DFE), serum folate, 5-methyltetrahydrofolate (5-MTHF), red blood cell (RBC) folate, and AFLD were evaluated using multivariable logistic regression, adjusting for demographic and clinical variables. In parallel, ethanol-fed C57BL/6J mice, with or without folic acid supplementation, and L02 hepatocyte models were used to assess biochemical markers, hepatic histology, and lipogen
