Deacetylation-dependent regulation of PARP1 by SIRT2 dictates ubiquitination of PARP1 in oxidative stress-induced vascular injury

open access: yesRedox Biology, 2021
Poly(ADP-ribose) polymerase 1 (PARP1) has a major regulatory role in cardiovascular disease. However, inhibiting PARP1 activity does not significantly improve clinical outcomes of cardiovascular disease, which suggests that the regulatory mechanism of ...

The multifaceted roles of PARP1 in DNA repair and chromatin remodelling

open access: yesNature Reviews Molecular Cell Biology, 2017
Cells are exposed to various endogenous and exogenous insults that induce DNA damage, which, if unrepaired, impairs genome integrity and leads to the development of various diseases, including cancer.

Therapeutic Potentials of Poly (ADP‐Ribose) Polymerase 1 (PARP1) Inhibition in Multiple Sclerosis and Animal Models: Concept Revisiting

open access: yesAdvanced Science, 2022
Poly (ADP‐ribose) polymerase 1 (PARP1) plays a fundamental role in DNA repair and gene expression. Excessive PARP1 hyperactivation, however, has been associated with cell death. PARP1 and/or its activity are dysregulated in the immune and central nervous

PARP1-DNA co-condensation drives DNA repair site assembly to prevent disjunction of broken DNA ends

open access: yesCell
DNA double-strand breaks (DSBs) are repaired at DSB sites. How DSB sites assemble and how broken DNA is prevented from separating is not understood. Here we uncover that the synapsis of broken DNA is mediated by the DSB sensor protein poly(ADP-ribose ...

Vascular Protection of Poly(ADP-ribose) Polymerase Inhibitors in the Combination Therapy With Vascular Endothelial Growth Factor Signaling Pathway Inhibitors [PDF]

open access: yesReviews in Cardiovascular Medicine
The Poly(ADP-ribose) polymerase (PARP) family comprises seventeen members that catalyze poly- or mono- adenosine diphosphate (ADP)-ribosylation, a pivotal post-translational modification regulating a wide array of cellular processes, including ...

Muscle PARP1 inhibition extends lifespan through AMPKα PARylation and activation in Drosophila

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2023
Significance The activity of PARP1 was increased in the skeletal muscle of aged humans, mice, and Drosophila. The knockdown of PARP1, specifically in muscle, extended the lifespan of Drosophila.

FANCJ promotes PARP1 activity during DNA replication that is essential in BRCA1 deficient cells

open access: yesNature Communications
The effectiveness of poly (ADP-ribose) polymerase inhibitors (PARPi) in creating single-stranded DNA gaps and inducing sensitivity requires the FANCJ DNA helicase. Yet, how FANCJ relates to PARP1 inhibition or trapping, which contribute to PARPi toxicity,

A unified mechanism for PARP inhibitor-induced PARP1 chromatin retention at DNA damage sites in living cells

open access: yesCell Reports
Summary: Poly(ADP-ribose) polymerase (PARP) inhibitors (PARPis) not only suppress PARP1 catalytic activity but also prolong its association to damaged chromatin.

PARP1 condensates differentially partition DNA repair proteins and enhance DNA ligation

open access: yesEMBO Reports
Poly(ADP-ribose) polymerase 1 (PARP1) is one of the first responders to DNA damage and plays crucial roles in recruiting DNA repair proteins through its activity – poly(ADP-ribosyl)ation (PARylation). The enrichment of DNA repair proteins at sites of DNA

THE PEPTIDOGLYCAN FRACTION ENRICHED WITH MURAMYL PENTAPEPTIDE FROM Lactobacillus bulgaricus INHIBITS GLIOBLASTOMA U373MG CELL MIGRATION CAPABILITY AND UPREGULATES PARP1 AND NF-kB LEVELS [PDF]

open access: yesBiotechnologia Acta, 2020
Peptidoglycan is a universal component of bacterial walls that exerts various biological activities, including tumoricidal effect. Anti-cancer effect of various peptidoglycan fractions and their derivates is different.
