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

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 ...

Poly(ADP‐Ribose) Polymerase in Plant Nuclei [PDF]

open access: yesEuropean 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

Poly(ADP‐ribose) polymerase is a zinc metalloenzyme [PDF]

open access: yesEuropean Journal of Biochemistry, 1984
Purified poly(ADP‐ribose) polymerase was inhibited by 1,10‐phenanthroline at pH <8. This inhibition and the inhibition by other chelating agents suggested that this enzyme was a metalloprotein. Atomic absorption spectroscopy showed the presence of one atom of zinc per protein molecule.

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.

Metabolic roles of poly(ADP-ribose) polymerases [PDF]

open access: yesSeminars in Cell & Developmental Biology, 2017
Poly(ADP-ribosyl)ation (PARylation) is an evolutionarily conserved reaction that had been associated with numerous cellular processes such as DNA repair, protein turnover, inflammatory regulation, aging or metabolic regulation. The metabolic regulatory tasks of poly(ADP-ribose) polymerases (PARPs) are complex, it is based on the regulation of metabolic

Pyridazine Based Compounds with PARP-1 Inhibitory Activity

open access: yesArchives 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 ...
