Background: Cardiac function in diabetic people is affected through different cellular mechanisms; One of these important cellular pathways is the c-Jun N-terminal kinases (JNKs), whose dysfunction can lead to heart failure; Therefore, the aim of this research is to investigate the effect of moderate intensity interval training on total and phosphorylated content of c-Jun N-terminal kinases protein in heart tissue of type 1 diabetic rats.
Methods: In this experimental study, 12 two-month-old male Sprague Dawley rats with an average weight of 300±20 grams were selected. Type 1 diabetes (blood sugar above 300) was induced to rats through intraperitoneal injection of streptozotocin (with a dose of 50 mg per kilogram of body weight) solution. The rats were randomly divided into two groups, diabetic training and diabetic control; The training group performed MIIT for four weeks at an intensity of 55-75% of maximum speed. Data analysis was done through independent t-test in GraphPad Prism software version 9.5. The significance level of the current research is P≤ 0.05.
Results: The intracellular content of JNK protein after four weeks of MIIT showed a significant decrease in both total (P= 0.01) and phosphorylated (P= 0.0001) forms. On the other hand, the ratio of total to phosphorylated intracellular content of JNK protein did not show a significant change after four weeks of MIIT (P= 0.23).
Conclusion: MIIT led to a decrease in the content of total and phosphorylated forms of JNK protein, which could possibly lead to less cell death in cardiac cells of diabetic subjects.
