Overexpressed ABCB1 Induces Olaparib-Taxane Cross-Resistance in Advanced Prostate Cancer [PDF]

Translational Oncology, 2019
Castration-resistant prostate cancer remains as an incurable disease. Exploiting DNA damage repair defects via inhibition of poly (ADP-ribose) polymerase (PARP) is becoming an attractive therapeutic option.

IGFBP3 promotes resistance to Olaparib via modulating EGFR signaling in advanced prostate cancer [PDF]

iScience
Summary: Olaparib is a pioneering PARP inhibitor (PARPi) approved for treating castration-resistant prostate cancer (CRPC) tumors harboring DNA repair defects, but clinical resistance has been documented.

A Quaternary Solid Dispersion System for Improving the Solubility of Olaparib

Solids
To improve the low solubility of poorly water soluble olaparib, in the following study, we prepared olaparib-loaded quaternary solid dispersions with hypromellose, Tween 20 or Labrasol, and colloidal silica.

The combination of olaparib and camptothecin for effective radiosensitization [PDF]

Radiation Oncology, 2012
Background Poly (ADP-ribose) polymerase-1 (PARP-1) is a key enzyme involved in the repair of radiation-induced single-strand DNA breaks. PARP inhibitors such as olaparib (KU-0059436, AZD-2281) enhance tumor sensitivity to radiation and to topoisomerase I

Differentially expressed proteins between olaparib-sensitive and olaparib-resistant triple-negative breast cancer cells

, 2021
To better understand the mechanism of PARPi resistance, two olaparib-resistant SUM159 and MDA468 cells were established by chronically exposing to olaparib. Olaparib-resistant SUM159 and MDA468 cells displayed 5-fold and 7-fold more resistant relative to

Targeting GALNT7 Disrupts the TAZ O-GalNAcylation Feedback Loop to Suppress Gallbladder Cancer Progression. [PDF]

Adv Sci (Weinh)
Aberrant GALNT7‐mediated O‐GalNAcylation stabilizes TAZ to drive gallbladder cancer progression through a feed‐forward transcriptional loop. Structure‐based screening identifies Olaparib as a potent GALNT7 antagonist that disrupts this oncogenic axis, providing an immediate therapeutic strategy for this aggressive malignancy.
