摘要
脆性 X 综合征(FXS)是由于脆性 X 信使核糖核蛋白 1(FMR1)基因突变引起的一种遗传病,会导致一系列发育问题,包括自闭症谱系障碍(ASD)的特征。二甲双胍是美国食品和药物管理局批准的一种抗糖尿病药物,根据动物实验(包括一项二甲双胍治疗可纠正 Fmr1 基因敲除小鼠 ASD 核心表型的实验),它已成为靶向治疗 FXS 的候选药物。现在,《美国国家科学院院刊》(PNAS)上的一项新研究表明,生命早期二甲双胍干预能有效治疗 Fmr1 KO 小鼠的 FXS 病理生理学。二甲双胍从出生起就能纠正 MAPK/ERK 和 mTORC1 信号通路,而这些通路在 FXS 中会出现信号增强。信号级联的减少纠正了行为缺陷,并使特定突触 FMRP 结合靶点的升高水平恢复正常,而这在之前使用成年 Fmr1 KO 小鼠进行的研究中并未观察到。总之,这些结果表明,FXS 患者一旦确诊,应尽早开始服用二甲双胍:Choi, J.H. et al.Natl.USA 121, e2407546121 (2024)
