RAD51 Mediates Resistance of Cancer Stem Cells to PARP Inhibition in Triple-Negative Breast Cancer

Abstract

Our data suggest that in both BRCA1-mutant and BRCA1-wild-type TNBCs, CSCs are relatively resistant to PARP inhibition. This resistance is mediated by RAD51, suggesting that strategies aimed at targeting RAD51 may increase the therapeutic efficacy of PARPi. Clin Cancer Res; 23(2); 514-22. ©2016 AACR.
