Abstract
OBJECTIVE
To investigate the effects of tomatidine (Td) on the progression of type 2 diabetes mellitus (T2DM) in mice and uncover the mechanism.
METHODS
T2DM mice model was induced by high-fat diet (HFD) and intrabitoneal injection of streptozotocin (STZ). The mice were grouped as follows: 1, control; 2, T2D; 3, T2D + tomatidine (5 mg/kg); 4, T2D + tomatidine (10 mg/kg); 5, T2D + tomatidine (20 mg/kg). Fasting blood glucose was detected by glucose metre and fasting insulin was detected by the kit to determine the effect of Td on T2DM mice. ELISA, qPCR, and Immunoblot assays were performed to detect the effects of Td on the hepatic glucose homeostasis and inflammation of mice. Immunoblot assays further confirmed the mechanism.
RESULTS
Td improved blood glucose and insulin resistance in T2DM mice. In addition, Td improved liver function and lipid metabolism disorder in T2DM mice. Td also affected the liver glucose homeostasis related genes in T2DM mice. Td alleviated serum inflammation in T2DM mice. We further found that Td activated AMPK pathway, therefore ameliorating T2DM.
CONCLUSION
Td ameliorated HFD/STZ-induced T2DM in mice, suggesting that it could serve as a drug of T2DM.
