Low-Frequency Electroacupuncture Improves Insulin Sensitivity in Obese Diabetic Mice through Activation of SIRT1/PGC-1 in Skeletal Muscle
Schematic model of electroacupuncture on insulin resistance in skeletal muscle. SIRT1-mediated deacetylation of PGC1α is required to activate genes that are associated with mitochondrial fatty acid oxidation in response to energy demands. The resultant increase in expression of mitochondrial genes, including NRF1, could exert positive effects on insulin signaling. eNOS: endothelial nitric oxide synthase; PGC1α: peroxisome proliferator-activated receptor γ coactivator 1α; SIRT1: Sirtuin 1; NRF1: nuclear respiratory factor 1.
