Streptavidin-Conjugated DNA for the Boronate Affinity-Based Detection of Poly(ADP-Ribose) Polymerase-1 with Improved Sensitivity

Biosensors, 2023
This work reports the development of a fluorescence method for the detection of poly(ADP-ribose) polymerase-1 (PARP1), in which a phenylboronic acid-modified fluorescein isothiocyanate dye (FITC-PBA) was used to recognize the formed poly(ADP-ribose) (PAR)

The Ups and Downs of Tannins as Inhibitors of Poly(ADP-Ribose)glycohydrolase

Molecules, 2011
DNA damage to cells activates nuclear poly(ADP-ribose)polymerases (PARPs) and the poly(ADP-ribose) (PAR) synthesized is rapidly cleaved into ADP-ribose (ADPR) by PAR glycohydrolase (PARG) action.

Research Advances in the Role of the Poly ADP Ribose Polymerase Family in Cancer

Frontiers in Oncology, 2021
Poly ADP ribose polymerases (PARPs) catalyze the modification of acceptor proteins, DNA, or RNA with ADP-ribose, which plays an important role in maintaining genomic stability and regulating signaling pathways. The rapid development of PARP1/2 inhibitors

Inhibiting poly(ADP-ribosylation) improves axon regeneration

eLife, 2016
The ability of a neuron to regenerate its axon after injury depends in part on its intrinsic regenerative potential. Here, we identify novel intrinsic regulators of axon regeneration: poly(ADP-ribose) glycohodrolases (PARGs) and poly(ADP-ribose ...

Poly(ADP-Ribose) Links the DNA Damage Response and Biomineralization

Cell Reports, 2019
Summary: Biomineralization of the extracellular matrix is an essential, regulated process. Inappropriate mineralization of bone and the vasculature has devastating effects on patient health, yet an integrated understanding of the chemical and cell ...

An Efficient Synthesis of PARP Inhibitors Containing a 4-Trifluoromethyl Substituted 3,6,7,7a-Tetrahydro- 1H-pyrrolo[3,4-d]pyrimidine-2,5-dione Scaffold

Журнал органічної та фармацевтичної хімії, 2023
Poly(ADP-ribose) polymerases (PARPs) are key enzymes in the DNA repair pathway. Inhibitors of these enzymes belong to a new type of anticancer drugs that selectively kill cancer cells by targeting the homologous recombination genetic defects.

Poly(ADP-ribose) Polymerase Null Mouse Cells Synthesize ADP-ribose Polymers [PDF]

Journal of Biological Chemistry, 1998
Poly(ADP-ribose) polymerase (PARP) (EC 2.4.2.30), the only enzyme known to synthesize ADP-ribose polymers from NAD+, is activated in response to DNA strand breaks and functions in the maintenance of genomic integrity. Mice homozygous for a disrupted gene encoding PARP are viable but have severe sensitivity to gamma-radiation and alkylating agents.

ADP-ribosylation: from molecular mechanisms to human disease [PDF]

Genetics and Molecular Biology
Post-translational modification of proteins by ADP-ribosylation, catalysed by poly (ADP-ribose) polymerases (PARPs) using NAD+ as a substrate, plays central roles in DNA damage signalling and repair, modulates a range of cellular signalling cascades and ...

Structures of the human poly (ADP-ribose) glycohydrolase catalytic domain confirm catalytic mechanism and explain inhibition by ADP-HPD derivatives. [PDF]

PLoS ONE, 2012
Poly(ADP-ribose) glycohydrolase (PARG) is the only enzyme known to catalyse hydrolysis of the O-glycosidic linkages of ADP-ribose polymers, thereby reversing the effects of poly(ADP-ribose) polymerases.
