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.

Modulation of energy homeostasis in maize and Arabidopsis to develop lines tolerant to drought, genotoxic and oxidative stresses [PDF]
Abiotic stresses cause crop losses worldwide that reduce the average yield by more than 50%. Due to the high energy consumed to enhance the respiration rates, the excessive reactive oxygen species release provokes cell death and, ultimately, whole plant ...

RNA Regulation by Poly(ADP-Ribose) Polymerases [PDF]
Posttranscriptional regulation of RNA facilitates the fine-tuning of gene expression. It occurs through multiple pathways that include the nuclear processing of mRNA and its precursors, mRNA silencing, regulation of mRNA decay, and regulation of translation. Poly(ADP-ribose) polymerases (PARPs), enzymes that modify target proteins with ADP-ribose, play

Recruitment of ubiquitin-activating enzyme UBA1 to DNA by poly(ADP-ribose) promotes ATR signalling
Human but not yeast UBA1 binds poly(ADP-ribose) polymers via a solvent-exposed and positively charged patch. Poly(ADP-ribose) polymerase 1–dependent recruitment of UBA1 to DNA ensures ataxia-telangiectasia and RAD3-related activation.

Role of poly(ADP-ribose)polymerase 2 in DNA repair [PDF]
Poly(ADP-ribosyl)ation is a posttranslational protein modification significant for the genomic stability and cell survival in response to DNA damage.

Poly(ADP-ribose) in the skin and in melanomas.
Cutaneous melanoma (CM) and uveal melanoma (UM) represent the most aggressive pigment cell tumor types. Our investigation examined the signaling molecule poly(ADP-ribose) (PAR) in CM and UM. We have demonstrated PAR in keratinocytes, sebocytes, hair follicles, endothelial cells and in subcutaneous adipocytes in the normal skin indicating that PAR may ...

Poly(ADP-ribose)polymerase activity controls plant growth by promoting leaf cell number [PDF]
A changing global environment, rising population and increasing demand for biofuels are challenging agriculture and creating a need for technologies to increase biomass production.

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.

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