TIMELESS Forms a Complex with PARP1 Distinct from Its Complex with TIPIN and Plays a Role in the DNA Damage Response [PDF]

open access: yesCell Reports, 2015
PARP1 is the main sensor of single- and double-strand breaks in DNA and, in building chains of poly(ADP-ribose), promotes the recruitment of many downstream signaling and effector proteins involved in the DNA damage response (DDR).

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

open access: yesRev Cardiovasc Med
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 ...

Nucleosome unwrapping and PARP1 allostery drive affinities for chromatin and DNA breaks. [PDF]

open access: yesNat Commun
Poly(ADP-ribose) polymerase 1 (PARP1) detects DNA strand breaks that occur in duplex DNA and chromatin. Here, correlative optical tweezers and fluorescence microscopy reveal how single molecules of PARP1 identify single-strand breaks (i.e., nicks ...

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 ...

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 ...

5mC-hydroxylase activity is influenced by the PARylation of TET1 enzyme [PDF]

open access: yes, 2015
5-hydroxymethylcytosine is a new epigenetic modification deriving from the oxidation of 5-methylcytosine by the TET hydroxylase enzymes. DNA hydroxymethylation drives DNA demethylation events and is involved in the control of gene expression ...

Dynamics of endogenous PARP1 and PARP2 during DNA damage revealed by live-cell single-molecule imaging

open access: yesiScience, 2023
Summary: PARP1 contributes to genome architecture and DNA damage repair through its dynamic association with chromatin. PARP1 and PARP2 (PARP1/2) recognize damaged DNA and recruit the DNA repair machinery.

PARP1 might enhance the therapeutic effect of tetrahydroxystilbene glucoside in traumatic brain injury via inhibition of Ras/JNK signalling pathway

open access: yesFolia Neuropathologica, 2020
Trauma is the main cause of death for people aged 1-45, and among them, traumatic brain injury (TBI) is the major condition, which causes over 50,000 deaths each year and costs over 80 billion per year.
