Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver pathologies. Molecular mechanisms of NAFLD pathogenesis are complex and still require further clarification. Thus, this study aimed to investigate the impact of lipoic acid (LA), widely used as an antioxidant, on the development of different links of NAFLD, including de novo lipogenesis, antioxidant and xenobiotic-metabolizing enzymes by gene expression analysis. The experiment was carried out on three groups of male Wistar rats received control diet, hypercaloric choline-deficient diet (HCCD) or HCCD with LA (HCCD+LA). In the liver of rats the expression of acetyl-CoA carboxylase 1 (Acaca), fatty acid synthase (Fasn), stearoyl-CoA desaturase (Scd) and transcriptional regulators sterol-regulatory element-binding protein SREBP (Srebf1), carbohydrate response element-binding protein ChREBP (Mlxipl), peroxisome proliferator-activated receptor alpha PPARα (Ppara), heme oxygenase-1 HO-1 (Hmox1) and nuclear erythroid 2-related factor 2 Nrf2 (Nrf2), cytochrome P450 1A1 CYP1A1 (CYP1A1) and aryl hydrocarbon receptor AhR (AhR), cytochrome P450 2E1 CYP2E1 (CYP2E1) genes were evaluated. Supplementation of HCCD with LA led to an even greater than in HCCD group decrease in Scd gene expression by 88% (p [ J Adv Biotechnol Exp Ther 2024; 7(3.000): 612-619]
