Abstract: Genome-wide studies have revealed that human and other mammalian genomes are pervasively transcribed
and produce thousands of regulatory non-protein-coding RNAs (ncRNAs), including miRNAs, siRNAs, piRNAs
and long non-coding RNAs (lncRNAs). Emerging evidences suggest that these ncRNAs also play a pivotal role in genome
integrity and stability via the regulation of DNA damage response (DDR). In this review, we discuss the recent
finding on the interplay of ncRNAs with the canonical DDR signaling pathway, with a particular emphasis on miRNAs
and lncRNAs. While the expression of ncRNAs is regulated in the DDR, the DDR is also subjected to regulation by
those DNA damage-responsive ncRNAs. In addition, the roles of those Dicer- and Drosha-dependent small RNAs
produced in the vicinity of double-strand breaks sites are also described. (ajcr0000149).

Keywords: DNA damage response, ncRNAs, miRNAs, lncRNAs, crosstalk
