BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is one of the primary causes of chronic liver disease and is closely linked to insulin resistance, type 2 diabetes mellitus (T2DM), and dyslipidemia. However, no effective drug therapies have been approved to treat this disease. The present research aimed to evaluate the therapeutic effects of the combination of oral hypoglycemic drug metformin (MET) and a natural product malvidin (MAL) on hepatic damage in HFD/STZ-induced diabetic rats.
METHODS: Sprague-Dawley rats were divided into five groups: normal control group (NC), diabetic control group (DC), DC+MET group, DC+MAL group, and DC+MET+MAL group and treated for eight weeks. Blood and liver tissue samples were collected for metabolic parameters, histological, and RT-qPCR analysis.
RESULTS: Our findings indicated that hyperglycemia, insulin resistance, hyperlipidemia, and non-alcoholic fatty liver disease (NAFLD) in diabetic rats were alleviated after oral treatment with MET and MAL, particularly their combination therapy. Besides, the expression of SREBP-1c, ACC, FAS, IL-6, IL-8, and NF-κB mRNA was down-regulated by MET+MAL, and the expression of PPARα, CPT1, and LPL was up-regulated by MET+MAL.
CONCLUSION: The evidence of this research indicated that the combination therapy may represent an efficient strategy against NAFLD in T2DM rats via improving lipid and glucose metabolisms, and inhibiting inflammation.
