Diabetologia:补充α-亚麻酸在白色脂肪组织线粒体生物能学的改善和全身葡萄糖平衡改善中的作用如何?

2018-04-24 MedSci MedSci原创

虽然目前关于胰岛素抵抗发生的潜在机制仍然不确定,但白色脂肪组织(WAT)和骨骼肌中的代谢功能障碍已牵涉到该过程中。因此,研究人员研究了补充α-亚麻酸(ALA)和运动训练对肥胖Zucker大鼠WAT和骨骼肌内全身葡萄糖稳态和线粒体生物能量学的独立及综合影响。近日,国际杂志 《Diabetologia》上在线发表一项关于补充α-亚麻酸对Zucker大鼠运动诱导的白色脂肪组织线粒体生物能学的改善和全身

虽然目前关于胰岛素抵抗发生的潜在机制仍然不确定,但白色脂肪组织(WAT)和骨骼肌中的代谢功能障碍已牵涉到该过程中。因此,研究人员研究了补充α-亚麻酸(ALA)和运动训练对肥胖Zucker大鼠WAT和骨骼肌内全身葡萄糖稳态和线粒体生物能量学的独立及综合影响。近日,国际杂志 《Diabetologia》上在线发表一项关于补充α-亚麻酸对Zucker大鼠运动诱导的白色脂肪组织线粒体生物能学的改善和全身葡萄糖平衡改善的研究。 研究人员随机分配肥胖的Zucker大鼠单独接受对照饮食或补充ALA并保持久坐或进行4周的运动训练(CON-Sed,ALA-Sed,CON-Ex和ALA-Ex组)。通过葡萄糖负荷的应答来确定全身葡萄糖耐量。在骨骼肌和附睾WAT(eWAT)中检测线粒体含量和生物能量学。采用Western印迹检测胰岛素敏感性和细胞应激。 运动训练提高了全身葡萄糖耐量以及肌肉和WAT中胰岛素诱导的信号传导。然而,运动训练期间ALA的消耗阻止了运动介导的全身葡萄糖耐量改善。ALA消耗量不影响骨骼肌、胰岛素敏感性和线粒体生物能量学的运动诱导适应性,相反,在eWAT中,补充ALA减弱了胰岛素信号传导,
