Effective DNA repair is essential for cell survival: a failure to correctly repair damage leads to the accumulation of mutations and is the driving force for carcinogenesis. Multiple pathways have evolved to protect against both intrinsic and extrinsic genotoxic events, and recent developments have highlighted an unforeseen critical role for RNA in ensuring genome stability. It is currently unclear exactly how RNA molecules participate in the repair pathways, although many models have been proposed and it is possible that RNA acts in diverse ways to facilitate DNA repair. A number of well-documented DNA repair factors have been described to have RNA-binding capacities and, moreover, screens investigating DNA-damage repair mechanisms have identified RNA-binding proteins as a major group of novel factors involved in DNA repair. In this review, we integrate some of these datasets to identify commonalities that might highlight novel and interesting factors for future investigations. This emerging role for RNA opens up a new dimension in the field of DNA repair; we discuss its impact on our current understanding of DNA repair processes and consider how it might influence cancer progression.

RNA在DNA双链断裂修复中的作用。



有效的DNA修复对于细胞生存至关重要:未能正确修复损伤会导致突变的积累,是致癌的驱动力。已经进化出多种途径来防止内在和外在的基因毒性事件,最近的发展凸显了 RNA 在确保基因组稳定性方面发挥着不可预见的关键作用。目前尚不清楚 RNA 分子如何参与修复途径,尽管已经提出了许多模型,并且 RNA 可能以多种方式发挥作用来促进 DNA 修复。许多有据可查的 DNA 修复因子已被描述为具有 RNA 结合能力,而且,研究 DNA 损伤修复机制的筛选已将 RNA 结合蛋白确定为参与 DNA 修复的一类主要的新因子。在这篇综述中,我们整合了其中一些数据集,以确定可能突出未来研究的新颖且有趣的因素的共性。 RNA 的这一新兴作用为 DNA 修复领域开辟了新的维度;我们讨论了它对我们目前对 DNA 修复过程的理解的影响,并考虑了它如何影响癌症进展。
