PARP inhibitors [PDF]

Hereditary Cancer in Clinical Practice, 2015
بوليميرازات بولي (ADP - ريبوز)، التي يتم اختصارها باسم PARPs، هي مجموعة من البروتينات المألوفة التي تلعب دورًا مركزيًا في إصلاح الحمض النووي باستخدام مسار إصلاح استئصال القاعدة (BER). هناك حوالي 17 بروتينًا في هذه العائلة منها PARPs النووية الأولية هي PARP -1 و PARP -2 و PARP -3 و tankyrases 1 و 2 (PARP -5a و -5b).

Drug-Induced Interstitial Lung Disease From PARP Inhibitors (Olaparib and Niraparib) for Ovarian Cancer

Annals of Internal Medicine: Clinical Cases, 2023
Poly (ADP-ribose) polymerase (PARP) inhibitors are approved for the treatment of several types of cancers. We report a case of an 80-year-old Japanese woman who developed drug-induced interstitial lung disease (ILD) during treatment with PARP inhibitors (

Combined inhibition of PARP and EZH2 for cancer treatment: Current status, opportunities, and challenges

Frontiers in Pharmacology, 2022
Tumors with BRCA1/2 mutations or homologous recombination repair defects are sensitive to PARP inhibitors through the mechanism of synthetic lethality. Several PARP inhibitors are currently approved for ovarian, breast and pancreatic cancer in clinical ...

PARP inhibition promotes ferroptosis via repressing SLC7A11 and synergizes with ferroptosis inducers in BRCA-proficient ovarian cancer

Redox Biology, 2021
Pharmacologic inhibition of PARP is the primary therapeutic strategy for BRCA mutant ovarian cancer. However, most of patients carry wild-type BRCA1/2 with no significant clinical benefits from PARP inhibitors, calling for the needs to further ...

In silico screening identifies a novel small molecule inhibitor that counteracts PARP inhibitor resistance in ovarian cancer

Scientific Reports, 2021
Poly ADP-ribose polymerase (PARP) inhibitors are promising targeted therapy for epithelial ovarian cancer (EOC) with BRCA mutations or defective homologous recombination (HR) repair. However, reversion of BRCA mutation and restoration of HR repair in EOC
