Poly(adenosine diphosphate ribose) polymerase inhibitors induce autophagy‐mediated drug resistance in ovarian cancer cells, xenografts, and patient‐derived xenograft models

PARP inhibitor-induced autophagy provides an adaptive mechanism of resistance to PARP inhibitors in cancer cells with wild-type BRCA, and a combination of PARP inhibitors with CQ or other autophagy inhibitors could improve outcomes for patients with ovarian cancer.
