探索肌动蛋白 feimin 的功能
骨骼肌产生一系列的肌肉因子,它们对全身有不同的影响。发表在《自然-代谢》(Nature Metabolism)杂志上的两项新研究发现了一种他们称之为feimin的肌肉因子,并描述了它对葡萄糖稳态和运动表现的影响。研究人员通过对小鼠进行全身敲除,或对不同器官特异性敲除模型(例如肠或肌肉)中的一种敲除,证明了feimin是在对喂养的反应中从骨骼肌分泌的。此外,与野生型小鼠相比,骨骼肌敲除编码feimin的基因的小鼠在喂食后血糖水平升高,肝脏和肌肉糖原储存减少。这一发现表明feimin在调节葡萄糖稳态中起作用。“与胰岛素的作用相反,我们的研究结果表明,feimin信号通过一种独特的机制起作用;它对AKT激活和葡萄糖调节的作用更慢,更弱,但更持久,”王解释说。“这表明胰岛素是一种粗略的调节机制,而feimin是精细调节葡萄糖稳态的机制。”
