Abstract

This study aims to investigate the effects of metformin and resveratrol on muscle insulin resistance with emphasis on the regulation of lipolysis in hypoxic adipose tissue. ICR mice were fed with high fat diet (HFD) for 10days with administration of metformin, resveratrol, or intraperitoneal injection of digoxin. Adipose hypoxia, inflammation and cAMP/PKA-dependent lipolysis were investigated. Moreover, lipid deposition and insulin resistance were examined in the muscle VSports手机版. Metformin and resveratrol attenuated adipose hypoxia, inhibited HIF-1α expression and inflammation in the adipose tissue of HFD-fed mice. Metformin and resveratrol inhibited lipolysis through prevention of PKA/HSL activation by decreasing the accumulation of cAMP via preserving PDE3B. Metformin and resveratrol reduced FFAs influx and DAG accumulation, and thus improved insulin signaling in the muscle by inhibiting PKCθ translocation. This study presents a new view of regulating lipid metabolism to ameliorate insulin resistance and provides the clinical guiding significance for obesity and type 2 diabetes with metformin and resveratrol treatment. .
