Methylation status of Dnmt1 promoter depends on poly(ADP-ribosy)lation [PDF]

, 2007
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 ...

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

, 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

NADP+ is an endogenous PARP inhibitor in DNA damage response and tumor suppression

Nature Communications, 2019
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 ...

Targeted Therapy in Ovarian Cancer

healthbook TIMES. Oncology Hematology, 2021
Ovarian cancer (OC) is associated with a dismal prognosis and lack of curative treatment. Increased understanding of OC biology has led to the development of several targeted therapies, including antiangiogenic agents and poly(ADP-ribose) polymerase ...

Identification of regulators of poly-ADP-ribose polymerase inhibitor response through complementary CRISPR knockout and activation screens

Nature Communications, 2020
Mutations in the homologous recombination proteins BRCA1 and BRCA2 can sensitize cells to treatment with inhibitors of poly-ADP-ribose polymerase 1 (PARPi), but resistance to the treatment can occur.

Radiosensitization with an inhibitor of poly(ADP-ribose) glycohydrolase: A comparison with the PARP1/2/3 inhibitor olaparib [PDF]

, 2018
Upon DNA binding the poly(ADP-ribose) polymerase family of enzymes (PARPs) add multiple ADP-ribose subunits to themselves and other acceptor proteins.

Quantitation of intracellular NAD(P)H can monitor an imbalance of DNA single strand break repair in base excision repair deficient cells in real time [PDF]

, 2003
DNA single strand breaks (SSBs) are one of the most frequent DNA lesions in genomic DNA generated either by oxidative stress or during the base excision repair pathways.

The role of histone modifications in transcription regulation upon DNA damage

FEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.
