五周亞極限強度運動對StAR及其調(diào)控因子的影響
[Abstract]:Aim: to study the temporal changes of the expression of PKAP-CREB and SF-1 associated with cholesterol transporter (StAR), and to explore the effects of 5-week sub-limit intensity exercise on serum testosterone level and StAR protein in rats, and to find out the causes of exercise low testosterone. To provide evidence for prevention and treatment of exercise low testosterone. Methods: thirty 8-week male Sprague-Dawley rats were divided into three groups: group A (weight bearing 5%) and group B (6% body weight). The rats in group A were given 4min 脳 5 swimming exercises at intervals of 90 seconds. The rats were trained once in the afternoon. The rats in group C were kept quietly for five weeks. The changes of CKBU T and StAR mRNA were detected 48 hours after training. Formal experiment: 90 male Sprague-Dawley rats at 8 weeks were divided into 5 exercise intervention groups: exercise 1 week (T1), exercise 2 weeks (T2), exercise 3 weeks (T3), exercise 4 weeks (T4), exercise 5 weeks (T5) and control group before and after exercise (C0 C5). The exercise group was trained with 6% body weight. After 48 hours of training, the samples were selected for testing. The changes of protein and gene mRNA were detected by Western blot- RT-PCR and other techniques, such as Starn PKA, pCREBEBSF-1 and so on. Results: the level of lactic acid in group A and group B was significantly higher than that in group C (P0.01) after exercise in group A and group B (P0.01), and there was a significant difference between group A and group B (P0.01). CK and BU were significantly increased in exercise intervention group (p0.01), but the expression of StAR mRNA in group B was significantly lower than that in group C (p0.05). In formal experiment 1, the serum testosterone level in the exercise intervention group decreased slowly in the first three weeks, then increased, and the serum testosterone level in the T5 group decreased by 70% (p0.01) .LH in comparison with the C0 group. In the fifth week, the LH level decreased more significantly than that of C0, and the difference was significant (p0.01). The level of 3min lactic acid in the exercise intervention group increased significantly after training. The trend of change was: the first three weeks increased greatly (p0.01), the latter two weeks maintained a higher level and slightly increased (p0.05) .SOD activity continued to decrease. In the fifth week, the activity of SOD decreased to 77% (p0.01). The content of SOD fluctuated slightly in the first three weeks, and increased significantly in the fourth and fifth weeks, which was significantly different from that in the C0 group (p0.01) .The expression of PKAP-CREBSF-1 protein in testis of rats remained stable in the first three weeks. The expression of StAR mRNA in the exercise intervention group did not change significantly in the first three weeks, but the expression of mRNA in the T5 group was significantly different from that in the quiet group (p0.05). The SF-1 mRNA increased slightly in the first week compared with that in the C _ 0 group, and then gradually decreased to the fifth week (p _ (0.01). Conclusion the level of peroxidation in testicular tissue was increased after 1 and 5 weeks of submaximum intensity exercise, and the serum testosterone level was increased. The decrease of StAR and its related regulatory factor PKApCREBSF-1 in Leydig cells of testis. 2StAR-related regulatory factors were inhibited, which led to the decrease of StAR mRNA expression and the restriction of cholesterol transport, which may be the cause of accelerating the decrease of testosterone.
