Unscheduled RNA-DNA hybrids promote the formation DNA double-strand breaks (DSBs) through poorly characterized mechanism. In this issue, Sollier et al. (2014) show that R-loops are processed by XPF and XPG, two structure-specific endonucleases of the NER pathway, to generate DSBs.
非计划 RNA-DNA 杂交体通过特征不明显的机制促进 DNA 双链断裂(DSBs)的形成。在本期中,Sollier 等人(2014)表明 R 环通过 XPF 和 XPG(NER 通路的两种结构特异性内切酶)进行加工,从而产生 DSBs。
