FNDC5,也称为纤维连接蛋白III型结构域包含蛋白5,是一种在多种组织中表达的跨膜蛋白。FNDC5的主要功能是作为肌肉因子(myokine)在运动后释放,其可被切割并分泌为一种名为irisin的新型激素。irisin在调节能量代谢、脂肪细胞褐变和认知功能等方面发挥着重要作用[4]。

FNDC5的表达受到多种因素的调控,包括运动、PGC-1α和基因多态性。运动可以诱导骨骼肌中的FNDC5表达,并促进irisin的分泌。PGC-1α是一种转录共激活因子,可以促进FNDC5的表达。FNDC5基因的某些单核苷酸多态性(SNPs)与代谢综合征、2型糖尿病和身体成分等表型相关[3,5]。

FNDC5在多种生物学过程中发挥着重要作用。首先,FNDC5可以促进脂肪细胞的褐变,增加能量消耗,改善肥胖和葡萄糖稳态[4]。其次,FNDC5可以增强脑源性神经营养因子(BDNF)的表达,改善认知功能,并可能对阿尔茨海默病等认知障碍的治疗具有潜在价值[1,6]。此外,FNDC5还可以影响骨骼肌的生理功能和系统性能量稳态,改善年龄相关的肌肉萎缩和代谢功能障碍[2]。

综上所述,FNDC5是一种重要的肌肉因子,在调节能量代谢、脂肪细胞褐变和认知功能等方面发挥着重要作用。FNDC5的表达受到多种因素的调控,包括运动、PGC-1α和基因多态性。FNDC5的研究有助于深入理解肌肉因子在生物学过程中的作用机制,为代谢性疾病和认知障碍的治疗和预防提供新的思路和策略。
