Chromosomal instability syndromes are sensitive to poly ADP-ribose polymerase inhibitors
Poly ADP-ribose polymerase inhibitors have been shown to target cells with homologous recombination DNA repair defects. We report that poly ADP-ribose polymerase inhibitors induces apoptosis in cells deficient in other key DNA repair components ...

Structural modeling of NAD+ binding modes to PARP-1
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 ...

ARH Family of ADP-Ribose-Acceptor Hydrolases
The ARH family of ADP-ribose-acceptor hydrolases consists of three 39-kDa members (ARH1-3), with similarities in amino acid sequence. ARH1 was identified based on its ability to cleave ADP-ribosyl-arginine synthesized by cholera toxin.

Human PARP1 substrates and regulators of its catalytic activity: An updated overview
Poly (ADP-ribose) polymerase 1 (PARP1) is a key DNA damage sensor that is recruited to damaged sites after DNA strand breaks to initiate DNA repair. This is achieved by catalyzing attachment of ADP-ribose moieties, which are donated from NAD+, on the ...

Radiotherapy-Poly(ADP-ribose) Polymerase Inhibitor Combinations: Progress to Date [PDF]
Radiation resistance remains a huge clinical problem for cancer patients and oncologists in the 21st century. In recent years, the mammalian DNA damage response (DDR) has been extensively characterized and shown to play a key role in determining cellular survival following ionizing radiation exposure.

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

Poly (ADP-Ribose) Polymerase Inhibitors in Patients With Urothelial Cancer
Poly ADP-ribose polymerase inhibitors (PARPis) have clinical activity in several cancers. The rationale of their therapeutic use in urothelial cancer (UC) resides in the high homologous-recombination repair (HRR) deficiency (HRD) prevalence and potential cross-sensitivity with platinum-based chemotherapy (PBCT).

Inputs and outputs of poly(ADP-ribosyl)ation: Relevance to oxidative stress
Oxidative stress can cause DNA breaks which induce activation of the DNA nick sensor enzyme poly(ADP-ribose) polymerase-1 (PARP-1), part of the 17 member PARP enzyme family.

Mechanisms of PARP inhibitor resistance in cancer and insights into the DNA damage response
Editorial summary Inhibitors of poly(ADP-ribose) polymerase (PARPi) have entered the clinic for the treatment of patients with cancers that lack homology-directed DNA repair, but drug resistance remains a clinical hurdle.

Poly(ADP-ribose) polymerase inhibitors as cancer therapy
Poly(ADP-ribose) polymerase (PARP) inhibitors are pharmacologic agents which primarily inhibit the PARP-1 and PARP-2 enzymes within the cell. Inhibition of PARP results in failure of base-excision repair (BER) to correct single-stranded breaks in DNA.
