Poly(ADP-ribose) polymerase-1 (PARP1) is a potential biomarker and therapeutic target for cancers that can catalyze the poly-ADP-ribosylation of nicotinamide adenine dinucleotide (NAD+) onto the acceptor proteins to form long poly(ADP-ribose) (PAR ...

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

Methylation status of Dnmt1 promoter depends on poly(ADP-ribosy)lation [PDF]
Research is focused on CpG islands and on the mechanism that poly(ADP-ribosyl)ation uses to defend the unmethylated state of these important DNA sequences which are located in the promoter regions of the housekeeping genes having a role of transcription ...

Summary: PARP inhibitors have been shown to radiosensitize tumor cells in both in vitro and in vivo studies. This is a phase I study that aims to determine the safety, tolerability, and maximally tolerated dose of talazoparib, a PARP inhibitor, when ...

Radiosensitization with an inhibitor of poly(ADP-ribose) glycohydrolase: A comparison with the PARP1/2/3 inhibitor olaparib [PDF]
Upon DNA binding the poly(ADP-ribose) polymerase family of enzymes (PARPs) add multiple ADP-ribose subunits to themselves and other acceptor proteins.

Poly (ADP-Ribose) Polymerase Inhibitors: Talazoparib in Ovarian Cancer and Beyond
Genetic complexity and DNA damage repair defects are common in different cancer types and can induce tumor-specific vulnerabilities. Poly(ADP-ribose) polymerase (PARP) inhibitors exploit defects in the DNA repair pathway through synthetic lethality and ...

NADP+ is an endogenous PARP inhibitor in DNA damage response and tumor suppression
Cancer cells respond differently to inhibitors of Poly (ADP-ribose) polymerase. Here the authors reveal that ovarian cancer cells with higher cellular NADP+ levels are more sensitive to clinically relevant PARP1 inhibitors and show that NADP+ act as an ...

Update on Poly-ADP-ribose polymerase inhibition for ovarian cancer treatment [PDF]
Background: Despite standard treatment for epithelial ovarian cancer (EOC), that involves cytoreductive surgery followed by platinum-based chemotherapy, and initial high response rates to these, up to 80 % of patients experience relapses with a median ...
