Structural modeling of NAD+ binding modes to PARP-1

open access: yesВавиловский журнал генетики и селекции, 2017
The nuclear protein poly (ADP-ribose) polymerase-1 (PARP-1) plays an important role in the signaling and repair of DNA. PARP-1 catalyses covalent binding of poly (ADP-ribose) polymers with itself as well as with other acceptor proteins using NAD+ as a ...

The potential role and application of PARP inhibitors in cancer treatment [PDF]

open access: yes, 2009
Background: Since many anti-cancer agents act by inflicting DNA damage on tumour cells, there is increasing interest in the use of inhibitors of DNA repair to increase the cytotoxicity of these agents.

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

open access: yesCell 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 ...

Nitrosative Stress as a Modulator of Inflammatory Change in a Model of Takotsubo Syndrome

open access: yesJACC: Basic to Translational Science, 2018
Summary: Previous studies have shown that patients with Takotsubo syndrome (TS) have supranormal nitric oxide signaling, and post-mortem studies of TS heart samples revealed nitrosative stress.

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

open access: yesPLoS 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 ...

PARP-3 and APLF function together to accelerate nonhomologous end joining [PDF]

open access: yes, 2010
PARP-3 is a member of the ADP-ribosyl transferase superfamily of unknown function. We show that PARP-3 is stimulated by DNA double-strand breaks (DSBs) in vitro and functions in the same pathway as the poly (ADP-ribose)-binding protein APLF to accelerate

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

open access: yesJournal 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.

Effects of niacin restriction on sirtuin and PARP responses to photodamage in human skin. [PDF]

open access: yes, 2012
Sirtuins (SIRTs) and poly(ADP-ribose) polymerases (PARPs), NAD(+)-dependent enzymes, link cellular energy status with responses to environmental stresses.

Mcl-1 suppresses abasic site repair following bile acid–induced hepatic cellular DNA damage

open access: yesTumor Biology, 2017
In cholestasis, increases in bile acid levels result in the generation of reactive oxygen species and the induction of DNA damage and mutation. It is believed that bile acid accumulation is associated with liver tumorigenesis. However, the mechanism that

DNA repair deficiency biomarkers and the 70-gene ultra-high risk signature as predictors of veliparib/carboplatin response in the I-SPY 2 breast cancer trial. [PDF]

open access: yes, 2017
Veliparib combined with carboplatin (VC) was an experimental regimen evaluated in the biomarker-rich neoadjuvant I-SPY 2 trial for breast cancer. VC showed improved efficacy in the triple negative signature.
