摘要:

背景:原癌基因c-Src在调节高血压等心血管系统疾病中起着重要的作用,目前尚未看到有关运动干预影响主动脉血管内皮细胞c-Src的表达和活来调节高血压的研究。

目的:观察有氧运动对自发性高血压大鼠主动脉血管内皮细胞c-Src mRNA表达和c-Src活性的影响。
方法:8只雄性Wistar大鼠作为正常对照组,16只自发性高血压大鼠随机分为自发性高血压组8只,自发性高血压运动组8只。自发性高血压运动组每天进行90 min无负重有氧游泳运动,6 d/周,共8周;正常对照组和自发性高血压组大鼠不做游泳运动。每周测定大鼠血压1次,8周后,测定各组大鼠主动脉血管内皮细胞c-Src mRNA表达和c-Src活性。
结果与结论:与自发性高血压组相比,自发性高血压运动组血压明显降低,主动脉血管内皮细胞c-Src mRNA表达和c-Src活性明显升高。与正常对照组相比,自发性高血压运动组大鼠主动脉血管内皮细胞c-Src活性和c-Src mRNA表达高于正常对照组和自发性高血压组(P < 0.01)。结果提示有氧运动可以促进自发性高血压大鼠主动脉血管内皮细胞c-Src活性和c-Src mRNA表达的增加。

Abstract:

BACKGROUND: Proto-oncogene c-Src plays an important role in regulating cardiovascular diseases such as hypertension. At present, there were no studies concerning exercise intervention effects on c-Src expression in aortic endothelial cells so as to regulate hypertension.

OBJECTIVE: To observe the effects of aerobic exercise on c-Src mRNA expression and c-Src activity in the aorta blood vessel endothelial cells of spontaneous hypertensive rats.
METHODS: A total of 8 male Wistar rats were considered as normal control group. Sixteen spontaneous hypertensive rats were randomly assigned to 8 rats as spontaneous hypertension group and 8 rats as spontaneous hypertension exercise group. Rats in the spontaneous hypertension exercise group carried on 90 minutes unloaded aerobic swimming every day, 6 days a week, for 8 weeks. The rats in the normal control group and spontaneous hypertension group did not swim. Blood pressure of rats was measured once a week. 8 weeks later, the c-Src mRNA expression and c-Src activity were determined in aortic vascular endothelial cells of rats in each group.
RESULTS AND CONCLUSION: Compared with spontaneous hypertension group, blood pressure was lower, but c-Src mRNA expression and c-Src activity were significantly higher in the spontaneous hypertension exercise group. The c-Src activity and c-Src mRNA expression were higher in the spontaneous hypertension exercise group than normal control group and spontaneous hypertension group (P < 0.01). Results indicated that aerobic exercise can promote the increase in c-Src activity and c-Src mRNA expression in aortic endothelial cells of spontaneous hypertensive rats.
