The epitranscriptome: reshaping the DNA damage response

Genomic instability poses a formidable threat to cellular vitality and wellbeing, prompting cells to deploy an intricate DNA damage response (DDR) mechanism. Recent evidence has suggested that RNA is intricately linked to the DDR by serving as template, scaffold, or regulator during the repair of DNA damage. Additionally, RNA molecules undergo modifications, contributing to the epitranscriptome, a dynamic regulatory layer influencing cellular responses to genotoxic stress. The intricate interplay between RNA and the DDR sheds new light on how the RNA epigenome contributes to the maintenance of genomic integrity and ultimately shapes the fate of damaged cells.
