An RNA link for METTL16 and DNA repair in PDAC

Increasing evidence links RNA methyltransferases to DNA damage repair. METTL16 is now shown to antagonize homologous recombination by preventing DNA-end resection via MRE11. Thus, METTL16 may represent a cancer vulnerability that can be used to identify patients able to benefit from combination therapies with DNA-damaging agents.
