The study investigated the effects of resveratrol, atorvastatin, and their combination on gene expression in the cholesterol metabolic pathway in fatty liver. The results showed that resveratrol and atorvastatin reduced fat accumulation in the liver and improved blood lipid profiles compared to the control group. The combination therapy had significant effects on the expression of genes related to cholesterol metabolism and miR33.
The present study was designed to evaluate the effects of resveratrol, atorvastatin, and a combination of resveratrol and atorvastatin on expression levels of genes involved in the cholesterol metabolic pathway in the fatty liver of C57/BL6 mice. A high-fat diet was used to induce fatty liver in C57/BL6 mice treated with resveratrol, atorvastatin, or a combination of resveratrol and atorvastatin. Pathological and biochemical studies were performed. In addition, hepatic gene expressions of ATP-binding cassette transporter A1 (ABCA1), ABCG1, liver X receptor (LXR)alpha, scavenger receptor B1 (SR-B1), low-density lipoprotein receptor (LDLR), and miR33 were evaluated by the real-time PCR method, and the Western blot method was used to measure the ABCA1, ABCG1, and LXR alpha protein levels. Resveratrol and atorvastatin reduced fat accumulation in the liver of mice with fatty liver, and this effect was correlated with decreased blood glucose levels, triglyceride, cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol blood levels compared with the positive control (PC) group. In contrast to the animals of the PC group, fatty liver groups that received resveratrol and atorvastatin had a significant effect on the mRNA levels of the ABCA1, ABCG1, LXR alpha, SR-B1, LDLR, and miR33 genes. Moreover, resveratrol and atorvastatin administration elevated ABCA1 and ABCG1 and reduced LXR alpha protein expression. Obtained results showed that resveratrol and atorvastatin combination therapy can improve nonalcoholic fatty liver disease by targeting genes involved in cholesterol metabolism and miR33.
