Core Tip

Core tip: Hepatic miR-192-5p levels decreased in non-alcoholic steatohepatitis rat models fed a high-fat diet and the decrease could be reversed after disease remission by liraglutide therapy. miR-192-5p showed a direct interaction with stearoyl-CoA desaturase 1 (SCD-1). miR-192-5p overexpression significantly alleviated lipid accumulation in Huh7 cells exposed to PA, and SCD-1 siRNA abrogated the lipid deposition aggravated by miR-192-5p inhibitor. Our study provides evidence that miR-192-5p participates in lipid synthesis in non-alcoholic fatty liver disease (NAFLD) through SCD-1 and suggests that the overexpression of miR-192-5p may represent a promising treatment for NAFLD.
