Epitranscriptomic RNA modifications in cancer DNA damage response: mechanistic links between RNA fate, genome maintenance, and therapy resistance
Abstract Epitranscriptomic RNA modifications have emerged as a fundamental regulatory layer linking RNA metabolism with genome maintenance, DNA damage response (DDR), and therapeutic resistance during cancer evolution. Throughout tumorigenesis, persistent oncogenic signaling, replication stress, oxidative stress, metabolic reprogramming, chronic inflammation, and anticancer treatments continuously generate DNA lesions that challenge genome integrity. Although the DDR network normally safeguards genomic stability by …
