- Paper Abstract
- AIMS: This study aimed to investigate oxymatrine via regulating miR-182 improved the hepatic lipid accumulation in non-alcoholic fatty liver disease (NAFLD) model. MATERIALS AND METHODS: Wistar rats were fed high-fat and high-fructose diet (HFDHFr group) for 4 weeks and HepG2 cells were treated with palmitic acid (PA group), and then were given oxymatrine intervention. The expression profiles of miRNAs were accessed by RNA sequencing (RNA-Seq). Hematoxylin-eosin (HE) staining and Oil Red O staining were used to observe the inflammation and lipid accumulation in liver. The levels of sterol regulatory element binding protein-1c (SREBP-1c), acetyl-CoA carboxylase (ACC), fatty-acid synthase (FAS) and carnitine palmitoyltransferase 1A (CPT-1A) were detected by RT-qPCR and Western blotting, respectively. Cell viability was detected by Cell Counting Kit-8 (CCK-8). KEY FINDINGS: miR-182 was down-regulated in the HFDHFr group and PA group. Oxymatrine reduced body weight, and improved glucose tolerance and insulin resistance in the HFDHFr + OMT group compared with HFDHFr group. In addition, oxymatrine reduced the ratio (liver weight/body weight), the content of triglycerides (TG), hepatic lipid accumulation and steatosis. The levels of SREBP-1c, ACC, and FAS were significantly decreased, while the CPT-1A level was obviously elevated after oxymatrine intervention (P < 0.05). In vivo, miR-182 knockdown increased the levels of SREBP-1c, ACC and FAS, while reduced the CPT-1A level. Additionally, oxymatrine attenuated the effects of miR-182 inhibitor on lipid accumulation. SIGNIFICANCE: We presented a possible mechanism that oxymatrine alleviated hepatic lipid metabolism via regulating miR-182 in NAFLD model.
