Background: SPTC is a mix of four herbal components (Salvia officinalis, Panax ginseng, Trigonella foenum-graeceum, and Cinnamomum zeylanicum) which may prevent the development of AGEs rich diet-induced diabetic complication and liver injury via activating the nuclear factor erythroid-2-related-factor-2 (Nrf2) pathway. Nrf2, as a master regulator of antioxidant response elements by activating cytoprotective genes expression, decreases oxidative stress associated with hyperglycemia and increases insulin sensitivity. We hypothesized that the combined effect of SPTC along with exercise could efficiently moderate oxidative stress with more favorable effects in the treatment of diabetes.Methods: We induced diabetes in C57BL/6 mice by AGEs using a diet supplementation and limitation of physical activity. After 16 weeks of intervention, AGEs fed mice were compared to control mice. Diabetic mice were assigned into seven experimental groups (n=5): diabetic mice, diabetic mice treated with SPTC (130 mg/kg), diabetic mice treated with Salvia Officinalis (60 mg/kg), diabetic mice treated with metformin (300 mg/kg), diabetic mice with endurance exercise training, diabetic mice treated with SPTC+metformin (the same as mentioned), diabetic mice treated with SPTC+exercise trainingResults: SPTC+exercise and SPTC+metformin reduced diabetic complications like gain weight, water, and calorie intake, blood glucose, insulin, and GLUT4 content more efficiently than each treatmen. These combinations improved oxidative stress hemostasis by activating the Nrf2 signaling pathway and attenuating keap1 protein more significantly.Conclusions: Eventually, combined treatment of SPTC with exercise and metformin as a novel approach had more beneficial effects to prevent the development of diabetes and oxidative stress associated with hyperglycemia. |
