Abstract B37: PARP inhibitor olaparib induces genomic instability in normal mammalian cells

Poly(ADP-ribose) polymerases (PARPs) are the first proteins involved in cellular DNA damage response pathways to be targeted by specific inhibitors for clinical benefit. Tumors with defects in homologous recombination (HR) are hypersensitive to PARP inhibitors (PARPi), and early phase clinical trials have been promising in patients with advanced BRCA1 and BRCA2-associated breast, ovary and prostate cancer. Unlike HR-defective cells,...
