Abstract
Acquired resistance limits the efficacy of PARP inhibitors (PARPi) in high grade serous ovarian cancer (HGSOC). Here, the authors show that inhibition of RNA polymerase I transcription using CX-5461 increases the therapeutic efficacy of PARPi and overcomes PARPi resistance in PDX models of HGSOC.
