Abstract
PARP inhibitors (PARPi) kill BRCA1/2-mutated cancers, which become resistant when DNA repair functions are restored. Now, MUS81 nuclease inhibition due to EZH2 downregulation is found to restore DNA replication fork protection but not repair, leading to PARPi-resistance in mutant BRCA2 cells and patients. This challenges the DNA repair dominance in synthetic lethality.Entities:
