Abstract

目的: 探讨耐力运动对小鼠骨骼肌葡萄糖摄取能力的影响及白细胞介素(IL-15)的作用机制。方法: 将32只C57BL/6J小鼠随机分为安静对照组(Control, C)、耐力训练组(Exercise, E)、PBS注射组(PBS injected, PI)、IL-15注射组(IL-15 injected, II)。每组8只,C组小鼠正常饲养8周,E组小鼠进行8周中等强度耐力训练,II组小鼠一次性腹腔注射300 μl IL-15复合剂溶液(1.5 μg IL-15和7 μg IL-15Rα),PI组一次性腹腔注射与II组等量的PBS。其中C组和E组在饲养第7周时,PI组和II组在一次性注射后,各组小鼠禁食12 h,随后进行葡萄糖耐量试验(IPGTT)检测并记录血糖水平。采用Western blot检测小鼠骨骼肌GLUT4、IL-15、AKT、pAKT、AMPK、pAMPK、AS160、pAS160的蛋白表达水平。结果: 与C组相比,E组小鼠骨骼肌IL-15、GLUT4、pAMPK、pAKT、pAS160蛋白表达明显升高(P＜0.05)。与PI组相比,II组小鼠骨骼肌IL-15、GLUT4、pAMPK、pAS160蛋白表达明显升高(P＜0.05)。结论: 8周耐力运动和腹腔注射IL-15复合剂均可提升小鼠骨骼肌葡萄糖的摄取能力,但单独增加IL-15可能是通过激活AMPK/AS160/GLUT4通路提升对于葡萄糖的转运能力,这一过程不依赖AKT/AS160/GLUT4通路的激活。.
