Resveratrol improves high-fat diet-induced insulin resistance in mice by downregulating the lncRNA NONMMUT008655.2.


ABSTRACT: As essential players in the field of diabetes treatment, resveratrol (RSV) has received much attention in recent years. However, it is unclear whether it can improve insulin resistance by regulating the long-chain non-coding RNA (lncRNA). The objective of this study was to investigate whether RSV improves high-fat diet-induced insulin resistance in mice by regulating thelncRNANONMMUT008655.2 in vivo and in vitro. To this end, animal and cell insulin resistance models were developed. Specifically, C57BL/6J mice were fed a high-fat diet (HFD) and administered RSV for eight weeks. Additionally, mouse Hepa cells were treated with palmitic acid, transfected with siRNA NONMMUT008655.2, and treated with RSV. Treated mice and cells were then compared to normal controls that were not exposed to RSV. In the animal model, RSV was found to decrease the levels of fasting blood glucose, triglycerides, and low-density lipoprotein cholesterol, as well as the insulin index and area under the curve; while increasing the insulin sensitivity index. Besides, RSV decreased the expression levels of SOCS3, G6PC, and FOXO1 yet increased that of p-Akt and p-FOXO1 in mice. The same results were observed following knockdown of NONMMUT008655.2 in cells. Overall, our results suggest that RSV may improve hepatic insulin resistance and control blood glucose levels by downregulating lncRNA NONMMUT008655.2.
