Abstract

DNA double-strand break DSB is the most deleterious form of DNA damage and poses great threat to genome stability. Eukaryotes have evolved complex mechanisms to repair DSBs through coordinated actions of protein sensors, transducers, and effectors. DSB-induced small RNAs diRNAs or Dicer-Drosha-dependent RNAs DDRNAs have been recently discovered in plants and vertebrates, adding an unsuspected RNA component into the DSB repair pathway. DiRNAs-DDRNAs control DNA damage response DDR activation by affecting DDR foci formation and cell cycle checkpoint enforcement and are required for efficient DSB repair. Here, we summarize the findings of diRNAs-DDRNAs and discuss the possible mechanisms through which they act to facilitate DSB repair.
