Background: Glycogen synthase kinase 3 beta is a key regulator of many signaling pathways. It is reported that Inhibition of this kinase results neuronal survival. Accordingly in this study we investigated the effect of endurance training on the gene expression of GSK-3β in the sensory areas of the spinal cord of male Wistar rats with diabetic neuropathy.

Methods: we randomly assigned 16 male Wistar rats into four groups: healthy control, healthy trained, neuropathy control, neuropathy trained. Intraperitoneal injection of a STZ (streptozotocin) solution (45 mg/kg) was used to induce diabetes. At two weeks after STZ injections, the mechanical allodynia and thermal hyperalgesia tests demonstrated the presence of diabetic neuropathy. A moderate endurance training protocol was performed for a six- week period. At 24 hours after the final training session, the rats were sacrificed and the L4-L6 sensory neurons of the spinal cord tissue were removed. GSK-3β mRNA expression was performed using real time-PCR.

Results: Statistical analysis shows that neuropathy trained experiences a decrease in gene expression in comparison to neuropathy control (P=0.02). On the other there was significant difference between healthy control and neuropathy control (P=0.02). However, there was no significant difference between healthy control and neuropathy trained.

Conclusion: we claim that endurance training will effectively decrease the expression of GSK-3β in the sensory areas of spinal cord of male Wistar rats with diabetic neuropathy. Endurance training as a non- pharmacotherapy strategy can modulate and return GSK-3β to approximate normal levels.

Background: The prevalence of type 2 diabetes is rapidly increasing in the world. As a result of this disease, long-term insulin resistance develops, as a result of which pancreatic beta cells are destroyed and disappear, as a result insulin is not released. Recently, a protein called lipasin, which is responsible for signaling the liver to beta cells, has been discovered, and previous reports have shown that lipasin/betatrophin increases pancreatic β cell proliferation. Therefore, the aim of this study was to investigate the effect of eight weeks of high intensity interval training (HIIT) and endurance training on lipasin gene expression in rats with type 2 diabetes.
Methods: The study was performed on 25 Wistar rats with a mean weight of 160±10 g and age of 8 weeks. After induction of diabetes, the rats were randomly divided into three groups of 6: control and endurance and HIIT. And exercise was performed for eight weeks (5 sessions per week). QRT-PCR technique was used to evaluate changes in hepatic lipasin gene expression.
Results: The present study showed that after eight weeks of endurance training and HIIT, the expression of lipasin gene in the liver of rats in the training group increased significantly compared to the control group (P = 0.037); Also, a significant negative correlation was observed between lipasin gene expression and insulin resistance index in the exercise group compared to the control group (r = -0.605, P = 0.037).
Conclusion: It seems that performing eight weeks of endurance training and HIIT, by increasing the expression of lipasin gene can increase beta cells in diabetic patients and may be an effective non-pharmacological intervention to reduce the symptoms of this disease.

Background: The pathway of insulin messengers is so important that diabetes can lead to disruption of this pathway. However, the aim of this study was to investigate the effect of 8 weeks of endurance training on protein Kinase-B (PKB or AKT) and mechanical target of rapamycin (mTOR) in the left ventricle of the heart of diabetic rats induced by streptozotocin and nicotinamide.
Methods: In this experimental study, 12 head two-month-old Sprague-Dawley rats with a mean weight of 270±20 g were selected. After diabetic induction with streptozotocin and Nicotinamide, rats were randomly assigned to two groups, training and control (6 heads in group each). The rat training program was performed on a treadmill for 8 weeks and 4 sessions per week, including 30 minutes of endurance training with an intensity of about 50 to 70% of the maximum speed. SPSS software and independent t-test were used to analyze the data.
Results: Eight weeks of endurance training resulted in a significant increase in protein Kinase-B content (P=0.03); But no significant change in Protein Mechanistic Target of Rapamycin content was observed in the endurance training group compared to the control (P=0.97).
Conclusion: protein Kinase-B is a key protein for regulating many cellular pathways, which was significantly increased by eight weeks of endurance training. Due to the fact that the content of protein mechanistic target of rapamycin does not change, it is possible that endurance training cannot lead to physiological hypertrophy heart through the mTORC1 pathway.
