PARP-1 activity (PAR) determines the sensitivity of cervical cancer to olaparib

Objectives Cervical cancer (CC) remains a major health problem worldwide. Poly (adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitors (PARPi) have emerged as a promising class of chemotherapeutics in ovarian cancer. We explored the preclinical in vitro and in vivo activity of olaparib against multiple primary whole exome sequenced (WES) CC cells lines and xenografts. Methods Olaparib cell-cycle, apoptosis,...
