811-ATF4调节CUX2神经元发育与DNA修复机制

这篇研究揭示了ATF4蛋白在哺乳动物大脑发育中维护基因组稳定性的关键机制。实验表明，ATF4通过直接调控CIRBP等因子来激活DNA损伤修复通路，协助神经祖细胞应对快速分裂产生的复制压力。研究重点指出，位于皮层上层的CUX2+神经元对该保护机制具有极高的依赖性，若缺失ATF4，这类细胞会因严重的DNA双链断裂和p53介导的细胞凋亡而选择性消失。这种发育缺陷不仅导致大脑皮层明显变薄，还可能与自闭症、精神分裂症及多种神经退行性疾病的病理机制密切相关。总而言之，该成果确定了ATF4是神经发育过程中必不可少的DNA损伤响应调节器。References:* Xia W, Morcom L, Xu Z, et al.
