Selective down-regulation of nuclear poly(ADP-ribose) glycohydrolase. [PDF]

PLoS ONE, 2009
The formation of ADP-ribose polymers on target proteins by poly(ADP-ribose) polymerases serves a variety of cell signaling functions. In addition, extensive activation of poly(ADP-ribose) polymerase-1 (PARP-1) is a dominant cause of cell death in ...

Chromatin composition is changed by poly(ADP-ribosyl)ation during chromatin immunoprecipitation. [PDF]

PLoS ONE, 2012
Chromatin-immunoprecipitation (ChIP) employs generally a mild formaldehyde cross-linking step, which is followed by isolation of specific protein-DNA complexes and subsequent PCR testing, to analyze DNA-protein interactions.

Nucleolar-nucleoplasmic shuttling of TARG1 and its control by DNA damage-induced poly-ADP-ribosylation and by nucleolar transcription

Scientific Reports, 2018
Macrodomains are conserved protein folds associated with ADP-ribose binding and turnover. ADP-ribosylation is a posttranslational modification catalyzed primarily by ARTD (aka PARP) enzymes in cells.

Linking DNA repair and cell cycle progression through serine ADP-ribosylation of histones

Nature Communications, 2022
Poly(ADP-ribose)-polymerases (PARPs) are a cornerstone of the DNA damage response that promote DNA repair by modifying target proteins with ADP-ribose.

Biallelic ADPRHL2 mutations in complex neuropathy affect ADP ribosylation and DNA damage response

Life Science Alliance, 2021
This work studies known and new ADPRHL2 mutations with different disease mechanisms overall indicating that loss of nuclear ARH3 alone is pathogenic via dysregulated nuclear ADP ribosylation.

Poly(ADP-ribose) polymerase regulates transient receptor potential channel M2-dependent calpain activation in rd1 mouse retinal degeneration

Neural Regeneration Research
Inherited retinal degeneration refers to untreatable blinding diseases characterized by progressive photoreceptor loss. Photoreceptor degeneration is often associated with an excessive activation of poly(ADP-ribose) polymerase and Ca2+-dependent calpain ...

Poly(ADP-ribose) and cancer research [PDF]

Carcinogenesis, 1983
Carcinogenesis is a multistep process initiated by DNA damage, gene mutation, gene rearrangment and gene translocation, and ending with phenotypic transformation to cancer cells. Seventeen years ago, a unique enzymatic reaction was found. This reaction was catalyzed by a nuclear enzyme which polymerizes ADP-ribose residues of /3-NAD + to make poly(ADP ...

Neurological and histological consequences induced by in vivo cerebral oxidative stress: evidence for beneficial effects of SRT1720, a sirtuin 1 activator, and sirtuin 1-mediated neuroprotective effects of poly(ADP-ribose) polymerase inhibition.

PLoS ONE, 2014
Poly(ADP-ribose)polymerase and sirtuin 1 are both NAD(+)-dependent enzymes. In vitro oxidative stress activates poly(ADP-ribose)polymerase, decreases NAD(+) level, sirtuin 1 activity and finally leads to cell death.

PARG suppresses tumorigenesis and downregulates genes controlling angiogenesis, inflammatory response, and immune cell recruitment

BMC Cancer, 2022
Chemokines are highly expressed in tumor microenvironment and play a critical role in all aspects of tumorigenesis, including the recruitment of tumor-promoting immune cells, activation of cancer-associated fibroblasts, angiogenesis, metastasis, and ...
