The underlying mechanism for the PARP and BRCA synthetic lethality: Clearing up the misunderstandings

Abstract Poly (ADP‐ribose) polymerase (PARP) inhibitors effectively kill tumours defective in the BRCA1 or BRCA2 genes through the concept of synthetic lethality. It is suggested that PARP inhibitors cause an increase in DNA single‐strand breaks (SSBs), which are converted during replication to irre... View More
