摘要 目的 :研究运动对SD大鼠骨骼肌细胞葡萄糖运载体 4 (GLUT4 )转位机制的影响。方法 :将SD大鼠随机分为 2组 :对照组和运动组。运动组大鼠进行 6周游泳训练。以Western印迹法对 2组大鼠骨骼肌细胞内膜和外膜的GLUT4含量进行检测 ,同时实验前后检测大鼠血清胰岛素和血糖浓度。结果 :运动组大鼠经过 6周游泳训练 ,与对照组大鼠相比 ,骨骼肌细胞内膜GLUT4含量增加 16 0 % (P <0 0 1) ,细胞外膜GLUT4含量增加 71 9% (P <0 0 1)。结论 :运动可促进骨骼肌细胞内膜GLUT4向细胞外膜转位 ,从而提高肌细胞对葡萄糖的摄取和利用。 ToinvestigatetheeffectofexerciseontranslocationofskeletalmusclecellGLUT4proteininrats,experimentalratswereran domizedintotwogroups :controlgroupandexercisegroup Exerciseratsweresubmittedtoswimfor 6weeks Afterskeletalmuscle plasmamembranesandtheintracellularmembraneswerepreparedandseparated ,GLUT4proteinwasdetectedbyWesternblotanaly sis,plasmaglucoseandseruminsulinconcentrationofratswerealsodetected Westernblotanalysisshowedthatintracellularmem branesGLUT4proteinofexerciseratsskeletalmuscleincreasedby 16 0 % (P <0 0 1)andplasmamembranesGLUT4proteinin creasedby 71 9% (P <0 0 1)ascomparedwiththecontrolrats ExercisetrainingcanamelioratetranslocationofGLUT4andraise theamountofGLUT4proteininplasmamembranesinrats,whichmayincreasetheutilizationofglucoseinskeletalmuscle
