Simultaneous Effect of Resistance Training and Endothelial Ancestral Cell Injection on Expression of MURF1 Muscle Degeneration Factor and Its Relationship with Insulin Resistance In STZ-Induced Diabetic Male Rats

Diabetes disorders can lead to muscular burnout. The aim of this study was to determine the simultaneous effect of resistance training and endothelial stem cell injection on the factor of degeneration in the muscles of diabetic rats.

36 male wistar rats (age 6 weeks with weight of 20±200g) were randomly divided into five groups of basic healthy, diabetic control (D), diabetic and resistance training (DR), untrained diabetic by injection of endothelial stem cells (DI), diabetic training by simultaneous injection of endothelial stem questions (DRI). Western blotting and insulin resistance index were measured by ELISA method to evaluate the changes in MURF1 expression. The data were analyzed by two-factor analysis of variance by SPSS software version 19 at a significant level of α≥%5.

In this study, 6 weeks of resistance training significantly reduced MURF1 and insulin resistance index. The interactive effect of resistance training and stem cell injection also resulted in a significant decrease in murf1 levels, but insulin resistance index was not significantly superior to only training or injection.

Based on the findings of this study, it can be stated that resistance training or injection of endothelial ancestral cells can improve muscular degeneration, but simultaneous use of these two strategies was not superior in reducing atrophy complications in diabetic rats.
