The Emerging Role of RNA Modifications in DNA Double-Strand Break Repair

Front Mol Biosci. 2021 Apr 29:8:664872. doi: 10.3389/fmolb.2021.664872. eCollection 2021.

Abstract

The correct repair of DNA double-strand breaks is essential for maintaining the stability of the genome, thus ensuring the survival and fitness of any living organism. Indeed, the repair of these lesions is a complicated affair, in which several pathways compete for the DNA ends in a complex balance. Thus, the fine-tuning of the DNA double-strand break repair pathway choice relies on the different regulatory layers that respond to environmental cues. Among those different tiers of regulation, RNA modifications have just emerged as a promising field.

Keywords: DNA repair; DNA resection; R-loop; RNA modification; homologous recombination.
