Background: Diabetic neuropathy leads to skeletal muscle atrophy however atrophy signaling mechanisms are not well documented. The aim of the present study was to investigate Sunday Driver (Syd) gene expression in soleus muscle of Wistar male rats with diabetic neuropathy. Methods: Twelve male Wistar rats were randomly assigned in 3 groups: diabetic trained, diabetic untrained and healthy control. Two weeks after STZ injection (45 mg/Kg), diabetic neuropathy was demonstrated with mechanical allodynia and thermal hyperalgesia tests and after which moderate endurance training protocol was performed for 6 weeks. 48 hours after final training session, the rats were dissected and soleus muscle tissues were removed. Also Sydgene expression was measured with Real time- PCR methods. Results: Soleus muscle weight was decreased in diabetic groups (P=0.001), but compared with diabetic untrained group, was higher in diabetic trained group (P=0.001). Sydgene expression in diabetic untrained group was higher than healthy control group (P=0.001). Also, compared with diabetic untrained group, training significantly decreased Sydgene expression and blood glucose levels in diabetic trained group. (P=0.001 and P=0.0001, respectively). Conclusion: In soleus muscle of diabetic rats, Sydm RNAup-regulation is involved in development of muscle atrophy and training as a non-pharmacotherapy strategy can modulate and get it close to normal levels. So, it is suggested that Syd should be noted as a novel treatment in diabetes disease.
