WebPARP inhibitor (PARPi) treatment prevents the repair of single-stranded DNA breaks and leads to DSBs in cells. BRCA1/2-deficient cells are unable to repair DSBs via the HR pathway, resulting in cell death . Consequently, PARP inhibition is considered a promising strategy for the treatment of BRCA1/2-deficient tumors through synthetic lethality WebApr 8, 2024 · The combined use of olaparib and palbociclib can inhibit the WNT pathway, which is not downregulated by single-agent olaparib treatment.
