اثرتمرین استقامتی بر میزان بیان ژن CDK5 در بخش حرکتی نخاع رت‌های نر ویستار دارای نوروپاتی دیابت

Background: Increased and decreased CDK5 gene expression regulation, as a protein kinase, is associated with launching death or survival pathways in the nervous system. According to the chronic effects of endurance training on growth Germination, Neuronal function and improvement of pathological conditions of neurodegenerative diseases, the aim of our study was to investigate the effect of 6 Weeks Endurance Training on Gene Expression of Cdk5 in spinal motor part of Male Wistar Rats with Diabetic Neuropathy. Methods: Twenty eight adult male Wistar rats ten year old in the weight range of 326.3±84gr, were randomly divided into four groups including healthy control (C), healthy training (HT), neuropathic control (N) and neuropathic training (NT). Diabetes was induced with one shut injection of STZ(45mg/Kg) and after confirmation of neuropathic condition with behavior tests, training groups performed 6 weeks endurance training(with moderate intensity and increasing) on the treadmill. CDK5 gene expression in Spinal motor segments forming the sciatic nerve was measured with Real time technique and calculated using the 2-ΔΔCT method. Results: After 6 weeks of endurance training, CDK5 gene expression in spinal motor part of (NT) group was significantly lower than the (NC) group, also, in comparison with neuropathy control, training led to significant decrease in blood glucose levels in neuropathic training group. Conclusion: According to the specific role of CDK5 in neuronal growth or death, our study showed the beneficial effects of Chronic endurance exercise on neural networks leading to reduced gene expression of CDK5 in a pathologic condition.
