Targeting the nucleotide salvage factor DNPH1 sensitizes BRCA -deficient cells to PARP inhibitors

Abstract excerpt

Three strikes to knock cancer out BRCA1 and BRCA2 are tumor-suppressor genes, and patients with mutations in these genes are predisposed to breast, ovarian, and other cancers. Because BRCA1 and BRCA2 mutations affect pathways involved in DNA break repair, these patients' tumors are usually vulnerable to treatments that further damage DNA repair, such as poly(ADP-ribose) polymerase (PARP) inhibitors, but they can...
