Low-Frequency Electroacupuncture Improves Insulin Sensitivity in Obese Diabetic Mice through Activation of SIRT1/PGC-1α in Skeletal Muscle

Figure 4: 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.

This study suggested a preliminary mechanism of electroacupuncture. Specifically, low-frequency EA improved insulin sensitivity in a mouse model of genetic insulin resistance and diabetes, at least in part, via stimulation of SIRT1/PGC-1α in the skeletal muscle. Events involved in this mechanism are presented in Figure 4. This effect leads to a net switch in the metabolic program of the organism to an adaptation that may be of benefit in the face of disorders characterized by insulin resistance. The study introduces an effective and safe activator (electroacupuncture) for SIRT1, offering a basis for applying acupuncture in clinical practice in the treatment of diseases related to insulin resistance.

Electroacupuncture for Painful Diabetic Peripheral Neuropathy

The participants in the EA group received EA treatment with a mixed current of 2 Hz/120 Hz at 12 acupuncture points (bilateral Zusanli [ST36], Xuanzhong [GB39], Yinlingquan [SP9], Sanyinjiao [SP6], Taichong [LR3], and Zulinqi [GB41]) twice per week for 8 weeks. Depending on the sites of pain, the additional acupuncture point Bafeng (EX-LE10) was available.

Electroacupuncture for Painful Diabetic Peripheral Neuropathy A Multicenter Randomized Assessor Blinded Controlled Trial

“To our knowledge, this is the first multicenter randomized controlled trial to evaluate the effectiveness and safety of EA treatment for the management in PDN. One limitation is that neither a placebo nor sham EA was used as an active control; therefore, the possibility of a placebo effect was not excluded. In conclusion, the results of this study
demonstrate that EA treatment is effective for reducing pain and improving sleep disturbance and quality of life in PDN. In addition, EA treatment was well tolerated and safe during this study. These findings suggest that EA treatment may be recommended as a nonpharmacological treatment for pain reduction in PDN.”
