N6-Methylation of Adenosine of FZD10 mRNA Contributes to PARP Inhibitor Resistance

Despite the high initial response rates to PARP inhibitors (PARPi) in BRCA-mutated epithelial ovarian cancers (EOC), PARPi resistance remains a major challenge. Chemical modifications of RNAs have emerged as a new layer of epigenetic gene regulation. N6-methyladenosine (m6A) is the most abundant chemical modification of mRNA, yet the role of m6A modification in PARPi resistance has not previously been explored. Here, we show that m6A...
