Abstract:
Type 2 diabetes mellitus develops due to a combination of genetic and environmental factors. C57BL/6 mice prone to obesity and leptin resistance were kept on a high-fat diet for 21 weeks. The animals showed a significant increase in fasting and postprandial glucose levels and body weight, the development of insulin resistance, and by week 18, an increase in the serum TNFα level. Metformin therapy at a dose of 250 mg/kg was effective against the background of disturbances in carbohydrate metabolism: animals showed a significant decrease in insulin resistance and TNFα level.
