Immunomodulatory Roles of PARP-1 and PARP-2: Impact on PARP-Centered Cancer Therapies [PDF]

Cancers, 2020
Poly(ADP-ribose) polymerase-1 (PARP-1) and PARP-2 are enzymes which post-translationally modify proteins through poly(ADP-ribosyl)ation (PARylation)—the transfer of ADP-ribose chains onto amino acid residues—with a resultant modulation of protein function.

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).

BLM helicase inhibition synergizes with PARP inhibition to improve the radiosensitivity of olaparib resistant non-small cell lung cancer cells by inhibiting homologous recombination repair

Cancer Biology & Medicine, 2022
Objective: We aimed to investigate the radiosensitizing efficacy of the poly-ADP-ribose polymerase (PARP) inhibitor, olaparib, and the Bloom syndrome protein (BLM) helicase inhibitor, ML216, in non-small cell lung cancer (NSCLC) cells.

Olaparib Combined with an ATR or Chk1 Inhibitor as a Treatment Strategy for Acquired Olaparib-Resistant BRCA1 Mutant Ovarian Cells

Diagnostics, 2020
Objective: Despite the promise of PARP inhibitors (PARPi) for treating BRCA1/2 mutated ovarian cancer (OC), drug resistance invariably develops. We hypothesized rationale drug combinations, targeting key molecules in DNA repair pathways and the cell ...

Approaches to PET Imaging of Glioblastoma

Molecules, 2020
Glioblastoma multiforme (GBM) is the deadliest type of brain tumor, affecting approximately three in 100,000 adults annually. Positron emission tomography (PET) imaging provides an important non-invasive method of measuring biochemically specific targets

Chemical genetics and proteome-wide site mapping reveal cysteine MARylation by PARP-7 on immune-relevant protein targets

eLife, 2021
Poly(ADP-ribose) polymerase 7 (PARP-7) has emerged as a critically important member of a large enzyme family that catalyzes ADP-ribosylation in mammalian cells. PARP-7 is a critical regulator of the innate immune response.

Cooperative targeting of PARP-1 domains to regulate metabolic and developmental genes

Frontiers in Endocrinology, 2023
PARP-1, also known as poly(ADP-ribose) polymerase 1, is a multifunctional nuclear enzyme that plays a critical role in transcriptional regulation through its three functional domains: the N-terminal DNA-binding domain (DBD) containing two zinc fingers ...
