Silencing of the Metabolic Gene HKDC1 Is Associated With Aging and Neurodegeneration in Mice and Humans

📜 Aging Cell (IF: 7.1)
研究揭示,代谢基因HKDC1的表达沉默是驱动衰老和神经退行病变的关键机制。在小鼠和人类中,HKDC1表达随年龄增长而下降,其原因是染色质构象变化阻碍了转录因子TFEB的结合,导致线粒体质量调控蛋白PINK1丢失、线粒体功能失调,进而促进细胞衰老和神经炎症。HKDC1脑特异性敲除小鼠表现出年龄相关的焦虑、记忆受损和神经炎症。该研究首次将染色质重塑、代谢调控与神经退行直接关联,为干预认知衰退提供了新靶点。
