Abstract Background Type 2 Diabetes Mellitus (T2DM) is definitely characterised by hyperglycemia due to the incidence of insulin resistance. Testosterone supplementation offers been shown to possess a positive co-relation with improved glycemic control in T2DM males. Clinical studies possess reported that Androgen Alternative Therapy (ART) to hypogonadic males with T2DM resulted in improved glycemic control and metabolic parameters, but, these studies did not address in detail how testosterone acted on the key glucose homeostatic organs. Method In this study, we delineate the effect of testosterone supplementation to high-fat diet (HFD) induced T2DM in male C57BL6J mice and the effect of testosterone supplementation on the skeletal muscle mass insulin responsiveness. We also studied the effect of testosterone on the insulin signaling pathway proteins in C2C12 myocyte cells to validate the in vivo findings. Results We TGX-221 inhibition found that testosterone experienced a potentiating effect on the skeletal muscle mass insulin signaling pathway to improve glycaemic control. We demonstrate that, in males, testosterone enhances skeletal muscle mass insulin responsiveness by potentiating the PI3K-AKT pathway. The testosterone treated animals showed significant increase in the skeletal muscle mass Insulin Receptor (IR), p85 subunit of PI3K, P-GSK3 (Ser-21), and P-AKT (Ser-473) levels when compared with the control animals; but there was no significant switch in total AKT and GSK3. Testosterone supplementation inhibited GSK3 in the myocytes in a PI3K/AKT pathway dependent manner; on the other hand GSK3 gene expression was reduced in the skeletal muscle mass upon testosterone supplementation. Conclusion Testosterone raises insulin responsiveness by potentiating insulin signaling in the skeletal muscle mass cells, which is in contrast to the improved insulin resistance in the liver of testosterone treated TGX-221 inhibition T2DM male animals.
