Inhibition of Translesion DNA Synthesis Sensitizes BRCA-Deficient Ovarian Cancer to PARP Inhibitors.
Poly(ADP-ribose) polymerase inhibitors (PARPi) exploit synthetic lethality to treat BRCA1/2-mutated ovarian cancer, yet clinical responses are often incomplete and resistance frequently emerges. PARPi exert cytotoxic effects by inhibiting single-strand break repair and trapping PARP on DNA, which impedes replication fo...
