Whole body vibration remodels skeletal muscle via autophagy and energy metabolism in diabetic mice

Hyperglycemia occurs due to a defect in insulin secretion or impaired biological functions, or both. The long-term hyperglycemia during diabetes causes chronic damage and dysfunction of various tissues.

Sumario:Hyperglycemia occurs due to a defect in insulin secretion or impaired biological functions, or both. The long-term hyperglycemia during diabetes causes chronic damage and dysfunction of various tissues. Whole body vibration (WBV) has significant effects on lipid and glucose metabolism and endocrine and motor systems. In order to explore the effects of WBV on skeletal muscle, mice trained for 12 weeks with WBV (15 Hz, 30 min) were used as experimental subjects and their skeletal muscle morphology under the pathological state of diabetes was observed. In addition, the blood lipids, blood glucose, gastrocnemius muscle glycogen and mRNA and protein levels of autophagy and glucose metabolism biomarkers were compared among the three groups of mice via western blot and RT-qPCR. The results showed that WBV can significantly reshape skeletal muscle morphology and upregulate high density lipoprotein. The expression of glucose-6-phosphatase (G6P), Beclin1 and Atg7 in the gastrocnemius muscle of the WBV group was significantly increased. Therefore, it can be concluded that WBV promotes skeletal muscle remodeling in diabetic mice. The present study confirmed that WBV can attenuate the development of diabetes melitus (DM) and lead to lower level low density lipoprotein in the blood. In addition, G6P level plays an important role in WBV-treated DM model and may be used to monitor the effect of WBV in patients. The findings of the present study may provide a new molecular basis for WBV to play a therapeutic role in the treatment of diabetes and may have potential clinical applications in the future.
