我们遗传物质的完整性不断受到众多内源性和外源性因素的攻击。 DNA损伤反应缺陷的后果在增殖细胞中得到了充分研究,特别是在癌症的发展方面,但其在神经系统中的确切作用却相对知之甚少。在这里,我们试图全面概述神经系统中基因组不稳定的后果。我们重点介绍由 DNA 修复因子突变引起的先天性综合征的神经病理学,并强调 DNA 损伤反应在神经发育中的重要性。此外,我们描述了最近的研究结果,这些研究结果表明,强大的 DNA 损伤反应也与衰老和与年龄相关的神经退行性疾病(如阿尔茨海默病和肌萎缩侧索硬化症)的表现密切相关。
The integrity of our genetic material is under constant attack from numerous endogenous and exogenous agents. The consequences of a defective DNA damage response are well studied in proliferating cells, especially with regards to the development of cancer, yet its precise roles in the nervous system are relatively poorly understood. Here we attempt to provide a comprehensive overview of the consequences of genomic instability in the nervous system. We highlight the neuropathology of congenital syndromes that result from mutations in DNA repair factors and underscore the importance of the DNA damage response in neural development. In addition, we describe the findings of recent studies, which reveal that a robust DNA damage response is also intimately connected to aging and the manifestation of age-related neurodegenerative disorders such as Alzheimer’s disease and amyotrophic lateral sclerosis.
