Abstract
Epitranscriptomic RNA modifications constitute a critical gene regulatory component that can affect cancer progression. Among these, the RNA N4-acetylcytidine (ac4C) modification, which is mediated by the ac4C writer N-acetyltransferase 10 (NAT10), regulates the stabilization of mRNA. Here, we identified that the ac4C modification is induced upon cisplatin treatment and correlates with chemoresistance in bladder cancer. Both in vitro and in vivo, NAT10 promoted cisplatin chemoresistance in bladder cancer cells by enhancing DNA damage repair (DDR). Mechanistically, NAT10 bound and stabilized AHNAK mRNA by protecting it from exonucleases, and AHNAK-mediated DDR was required for NAT10-induced cisplatin…
