摘要 目的:检测分析急性力竭运动对大鼠心肌蛋白激酶C(PKC)α、δ和ε亚型总蛋白及其磷酸化蛋白表达的影响。方法:健康雄性SD大鼠50只,随机分为对照组(C组)和急性力竭运动组(AEE组)(n=25),采用一次力竭跑台运动建立急性力竭运动模型,Western blot法检测PKCα、δ和ε总蛋白及其磷酸化蛋白的表达水平。结果:与C组比较,AEE组大鼠心肌PKCα、p-PKCα^(Ser-657)、PKCδ、P-pKCδ^(Thr-507)及PKCε水平均显著升高(P<0.0S)。结论:急性力竭运动导致PKCα、PKCδ、PKCε表达水平和PKCα、PKCδ活化水平上调,可能是急性力竭运动导致大鼠心肌损伤的重要因素,三亚型之间的交互作用可能是更重要的因素。
