Effects of Lipoic Acid and High-Intensity Interval Training (HIIT) on Pancreatic VEGFR-3 Levels in Diabetic Rat Model

Abstract

Objective: The purpose of this experimental research is to investigate the effects of High-Intensity Interval Training (HIIT) and Lipoic Acid )ALA( supplementation on VEGFR-3 of pancreatic in diabetic Wistar rats model. Materials and Methods: 20 male Wistar rats weighing 159 ± 3 gr and aged3 weeks, were randomly assigned into 4 groups:1) diabetes/sham, 2)diabetes/ ALA, 3)diabetes/exercise/sham, and 4) diabetes /exercise/ ALA. Diabetes was induced with streptozotocin (65 mg/kg dose) and Nicotinamide (120 mg/kg dose). After two weeks of familiarization with interval training, the rats started their main training, included 10 repetitions of 4 minutes of running on the treadmill with an intensity of 85-90% VO2max and 2 minutes of active rest between repetitions (5-10 m/min) for 5 sessions per week for 6 weeks. ALA supplement was taken at a dose of 20 mg/kg/day for 6 weeks. One-way ANOVA test used and Tukey's post hoc test at for analysis (P≤ 0.05). Results: HIIT has a significant effect on blood glucose (P= 0.004) and insulin (P= 0.001) and VEGFR3 (P= 0.001) of pancreatic tissue of diabetic rats. Conclusion: Lymphatic vessels play an important role in the pancreas and treat diabetes.The results of this research showed that HIIT and ALA increased lymphangiogenesis in the diabetic rat model.
