Unc-51 Like Autophagy Activating Kinase-1 (ULK1) and FAK Family Kinase-Interacting Protein of 200 kDa (FIP200) play an essential role in controlling autophagy and muscle volume. The aim of this research is to investigate the effect of endurance training on the intracellular content of ULK1 and FIP200 proteins in the left ventricular of rats with type 1 diabetes.
In this experimental study, 18 rats 2-month-old male Sprague-Dawley rats with a mean weight of 300±20g were selected. 12 rats became diabetic by intraperitoneal injection of Streptozotocin solutions. These rats were randomly divided into 2 groups: diabetic training and diabetic control (6 heads per group); A healthy control group (6 heads)was also considered. The training group practiced endurance training 4 days a week for 6 weeks. Data were analyzed using SPSS software version 23 and one-way ANOVA and Tukey post hoc tests.
The content of ULK1 (increase) and FIP200 (decrease) after endurance training showed a significant change among the research groups in the left ventricular (P=0.0001). Tukey's post hoc test showed that this change is significant between the pair of diabetic training groups to diabetic control, diabetic training to healthy groups, and also diabetic control to healthy groups (P≤0.05).
Endurance training showed that it can have a dual nature to control autophagy in diabetic subjects by increasing ULK1 and decreasing FIP200. There is a need for more investigations in the field of exercise physiology on the proteins responsible for autophagy, especially in type 1 diabetes subjects.
