Novel modulators of poly(ADP-ribose) polymerase [PDF]
Trends in Pharmacological Sciences, 2006 The nuclear enzyme poly(ADP-ribose) polymerase (PARP)-1 has an important role in regulating cell death and cellular responses to DNA repair. Pharmacological inhibitors of PARP have entered clinical testing as cytoprotective agents in cardiovascular diseases and as adjunct antitumor therapeutics.

PARP-1 regulates DNA repair factor availability. [PDF]
, 2018 PARP-1 holds major functions on chromatin, DNA damage repair and transcriptional regulation, both of which are relevant in the context of cancer. Here, unbiased transcriptional profiling revealed the downstream transcriptional profile of PARP-1 enzymatic

Inputs and outputs of poly(ADP-ribosyl)ation: Relevance to oxidative stress
Redox Biology, 2014 Oxidative stress can cause DNA breaks which induce activation of the DNA nick sensor enzyme poly(ADP-ribose) polymerase-1 (PARP-1), part of the 17 member PARP enzyme family.

Pyridazine Based Compounds with PARP-1 Inhibitory Activity
Archives of Pharmaceutical Sciences Ain Shams University, 2023 Pyridazine-containing compounds have been identified as potent PARP1 inhibitors. The PARP is a family of enzymes essential for many cellular processes such as DNA repair, genomic stability, and apoptosis, also known as poly(ADP-ribose) synthetases and ...

Poly(ADP‐Ribose) Polymerase in Plant Nuclei [PDF]
European Journal of Biochemistry, 1994 We show that poly(ADP‐ribose) polymerase is present in maize, pea and wheat nuclei. We have identified the enzyme product as poly(ADP‐ribose) by purification and electrophoresis on a DNA sequencing gel. This reveals a polymer ladder consisting of up to 45 residues. The polymer product from maize, after digestion with snake venom phosphodiesterase, gave

Nature Communications, 2022 Poly(ADP) ribose polymerase (PARP) activity promotes, but is not required for, chromosome break repair by polymerase theta-mediated end joining (TMEJ). PARP activity promotes TMEJ by stimulating resection, a process that controls pathway choice.

Mechanisms of PARP inhibitor resistance in cancer and insights into the DNA damage response
Genome Medicine, 2018 Editorial summary Inhibitors of poly(ADP-ribose) polymerase (PARPi) have entered the clinic for the treatment of patients with cancers that lack homology-directed DNA repair, but drug resistance remains a clinical hurdle.
