• Resumen

  • Targeting disorders of glucose metabolism and the occurrence of hyperglycemia provides a potential therapeutic strategy for balancing energy to reduce insulin resistance such as type 2 diabetes. The present study investigated whether theasaponin E1 regulate energy metabolism in skeletal muscle cells. C2C12 mouse myoblasts were differentiated into myotubes . An MTT colorimetric assay verified cell viability. Theasaponin E1 (30, 45 or 60 mg/ ml), or metformin (2.5 mM), insulin (150 nM) for reference were used to treat the C2C12 myotubes. The expressions of energy metabolism were measured by western blotting in C2C12 myotubes. 2-NBDG kit to detect the glucose uptake capacity. Theasaponin E1 Treatment increases glucose uptake,GSK 3 β, as well as increases to the glycogen synthesis through the PI3K/AKT/mTOR signaling pathway, while reducing AMPK and ACC activities, and reducing the adipose synthesis pathway. These results suggest that theasaponin E1 may be increases glucose uptake by improving muscle energy metabolism.
