【摘要】：目的:探討不同時間一次有氧運動對小鼠骨骼肌NF-E2相關因子(NF-E2-related factor 2,Nrf2)與Kelch樣環(huán)氧氯丙烷相關蛋白-1(Kelch-like ECH-associated protein-1,Keapl)結合作用的影響。方法:C57BL/6J小鼠30只,按體重隨機分為安靜對照組(0 h組)和一次有氧運動3小時組(3 h組)、一次有氧運動6小時組(6 h組),每組10只。0 h組安靜飼養(yǎng),3 h組和6 h組小鼠分別進行3小時和6小時的一次有氧跑臺訓練,跑速為15 m/min,坡度為0。運動后即刻取后腿骨骼肌。高質熒光測定法檢測小鼠骨骼肌活性氧(ROS)水平;免疫共沉淀法測Nrf2/Keap1結合量;Western Blot法測定骨骼肌總Nrf2、Keap1蛋白表達量和細胞核Nrf2蛋白表達量。結果:與0 h組相比,6 h組ROS水平顯著高于0 h組(P0.05);3h、6 h組小鼠骨骼肌中Nrf2/Keap1結合量顯著降低(P0.05);3 h、6 h組小鼠骨骼肌總Nrf2蛋白表達顯著升高(P0.05),6 h組小鼠骨骼肌細胞核Nrf2蛋白表達顯著增加且與3h組相比也顯著增加(P0.05);小鼠骨骼肌總Keap1蛋白表達基本無變化。結論:一次有氧運動對小鼠骨骼肌Nrf2與Keap1解綁和Nrf2轉位入核的影響與運動時間的長短有關。
[Abstract]:Aim: to investigate the effect of aerobic exercise at different times on the binding of NF-E2 related factor NF-E2-related factor 2nrf2) to Kelch like epichlorohydrin associated protein-1 Kelch-like ECH-associated protein-1 Keapl. in mice skeletal muscle. Methods 30 C57BL / 6J mice, According to body weight, they were randomly divided into three groups: the control group (0 h), the 3 h aerobic exercise group (3 h group) and the 6 hour aerobic exercise group (6 h group). 10 rats in each group were fed quietly for 3 h and 6 h group respectively An hour and six hours of aerobic treadmill training, Running at a speed of 15 m / min, with a slope of 0. Take back leg skeletal muscle immediately after exercise. High quality fluorescence assay was used to detect the level of reactive oxygen species (Ros) in skeletal muscle of mice, and the expression of total Nrf2Keap1 protein and nuclear Nrf2 protein were measured by immunoprecipitation method and Western Blot method. Results: compared with the 0 h group, the ROS level of the 6 h group was significantly higher than that of the 0 h group P0.05 + 3 h group. The Nrf2/Keap1 binding capacity in the skeletal muscle of the mice was significantly lower than that of the 0 h group. The expression of total Nrf2 protein in the skeletal muscle of the mice in the P0. 05 h group was significantly higher than that in the 0 h group. The expression of total Nrf2 protein in the skeletal muscle of the 6 h group was significantly higher than that of the 0 h group. Compared with the 3h group, the protein expression increased significantly, and the expression of total Keap1 protein in the skeletal muscle of mice showed no change. Conclusion: the effect of one aerobic exercise on Nrf2 and Keap1 untying and Nrf2 transposition into nucleus is related to the duration of exercise.
