Abstract
Background: The Purpose of this study was to evaluate the effect of High Intensity Interval Training & Royal Jelly on expression of the genes of the hepatic miR-423-5P - FAM3A-AKt2 pathway in rats.
Methods: The statistical population was 36 male Wistar rats and reaching a weight of 193 ± 20 grams, they were subjected to a high-fat diet diet and intraperitoneal injection of 25 mg STZ. Blood sugar above 150 to 400 mg/dl was considered as a criterion to ensure that the mice had type 2 diabetes. Then divided into 4 groups (diabetic control group, intermittent exercise, Royal Jelly and exercise-Royal Jelly group). The experimental group of did HIIT with a 20 to 36 m/min. for 8 weeks. Royal jelly experimental groups consumed 100 mg/kg royal Jelly. 48 hours after the last training session, the mice were anesthetized with ether and blood was taken from the heart and tissue was removed, including liver tissue, and the tissue sample was transferred to a freezer temperature of -80. Serum glucose measurements were performed by an Auto analyzer. Insulin was measured by an ELISA kit, and the insulin resistance index was measured by formulas. The expression level of miRNA-423-5P, FAM3A and AKt genes in liver tissue was measured using Real Time-PCR method .the data, analyzed by one-way analysis of variance and Bonferroni’s post hoc and univariate and effect size. The significance level was considered to be p≥ 0.05.
Results: The findings showed that the expression of the hepatic miR-423-5P gene in the experimental groups of intermittent exercise with royal jelly and the exercise group and the gel group significantly decreased compared to the control group, and the expression of the FAM3A gene increased in the experimental groups compared to the control group. Non-significant and the expression of AKt2 gene in the training group and the training group with gel increased significantly compared to the control group, and in the gel group only compared to the control group, there was a non-significant increase, Also, there was a significant decrease in glucose in the experimental groups of HIIT exercise and HIIT- Royal jelly compared to the diabetic control group (p <0.05).Expression of the miR-423-5P gene was significantly lower in all groups compared to control, expression of mRNA FAM3 had insignificant increase and expression of mRNA AKt2 had a significant increase in groups of regular exercise and exercise with nutritional intervention. This gene had an insignificant increase of expression in the group with only nutritional intervention.
Conclusion: It seems that HIIT and royal jelly consumption, both alone and in combination, although with greater effect, can create favorable changes in the expression of Mir 4235p. FAM3A and AKt2 help to improve the condition of the liver.
