Nevertheless, resistance to PARP inhibitors often develops. Thus, it is imperative to identify strategies or targets that can enhance the efficacy of PARP inhibitors. In this study, we demonstrated that TNBC cells lacking N-acetyltransferase 10 (NAT10) exhibited greater sensitivity to olaparib and extensive DNA double-strand breaks (DSBs).

Remarkably, the combination of olaparib and remodelin, an inhibitor of NAT10, induced robust anti-tumor effects <em>in vitro</em> and <em>in vivo</em> by promoting DSBs.
