Alpha-lipoic acid (ALA), a naturally occurring antioxidant, was shown to decrease lipid accumulation in skeletal muscle by activating AMPK. Fatty liver is common in obese subjects with insulin resistance. Hepatic expression of SREBP-1c, which plays a majorrole in hepatic steatosis, is regulated by multiple factors, including insulin, AMP-activated protein kinase (AMPK), liver X receptors (LXRs) and specificity protein 1 (Sp1). Here we show that ALA decreases hepatic steatosis and SREBP-1c expression in rats on a high fat diet or given an LXR agonist. ALA increasedAMPK phosphorylation in the liver and in cultured liver cells, and dominant-negative AMPK partially prevented ALA-induced suppression of insulin-stimulated SREBP-1c expression. ALA also inhibited DNA-binding activity and transcriptional activity of both Sp1 and LXR. These results show that ALA prevents fatty liver disease through multiple mechanisms, and suggest that ALA can be used to prevent the development and progression of nonalcoholic fatty liver disease in patients with insulin resistance.
