Cas9 is mostly orthogonal to human systems of DNA break sensing and repair.

open access: yesPLoS ONE, 2023
CRISPR/Cas9 system is а powerful gene editing tool based on the RNA-guided cleavage of target DNA. The Cas9 activity can be modulated by proteins involved in DNA damage signalling and repair due to their interaction with double- and single-strand breaks (

Protein poly(ADP-ribosyl)ation regulates arabidopsis immune gene expression and defense responses. [PDF]

open access: yesPLoS Genetics, 2015
Perception of microbe-associated molecular patterns (MAMPs) elicits transcriptional reprogramming in hosts and activates defense to pathogen attacks. The molecular mechanisms underlying plant pattern-triggered immunity remain elusive.

Selective down-regulation of nuclear poly(ADP-ribose) glycohydrolase. [PDF]

open access: yesPLoS ONE, 2009
The formation of ADP-ribose polymers on target proteins by poly(ADP-ribose) polymerases serves a variety of cell signaling functions. In addition, extensive activation of poly(ADP-ribose) polymerase-1 (PARP-1) is a dominant cause of cell death in ...

Kynurenine–PARP-1 Link Mediated by MicroRNA 210 May Be Dysregulated in Pulmonary Hypertension

open access: yesAnatolian Journal of Cardiology, 2022
Background: Dysregulation of microRNAs is associated with pulmonary hypertension. The present study aimed to determine the alterations in microRNA and microRNA expressions and their role in signaling pathways and investigate the relationship with serum ...

Chromatin composition is changed by poly(ADP-ribosyl)ation during chromatin immunoprecipitation. [PDF]

open access: yesPLoS ONE, 2012
Chromatin-immunoprecipitation (ChIP) employs generally a mild formaldehyde cross-linking step, which is followed by isolation of specific protein-DNA complexes and subsequent PCR testing, to analyze DNA-protein interactions.

Neurological and histological consequences induced by in vivo cerebral oxidative stress: evidence for beneficial effects of SRT1720, a sirtuin 1 activator, and sirtuin 1-mediated neuroprotective effects of poly(ADP-ribose) polymerase inhibition.

open access: yesPLoS ONE, 2014
Poly(ADP-ribose)polymerase and sirtuin 1 are both NAD(+)-dependent enzymes. In vitro oxidative stress activates poly(ADP-ribose)polymerase, decreases NAD(+) level, sirtuin 1 activity and finally leads to cell death.

Structural modeling of NAD+ binding modes to PARP-1

open access: yesВавиловский журнал генетики и селекции, 2017
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 ...

Recruitment of ubiquitin-activating enzyme UBA1 to DNA by poly(ADP-ribose) promotes ATR signalling

open access: yesLife Science Alliance, 2018
Human but not yeast UBA1 binds poly(ADP-ribose) polymers via a solvent-exposed and positively charged patch. Poly(ADP-ribose) polymerase 1–dependent recruitment of UBA1 to DNA ensures ataxia-telangiectasia and RAD3-related activation.

Automodified Poly(ADP-Ribose) Polymerase Analysisto Monitor DNA Damagein Peripheral Lymphocytes of Floriculturists Occupationally Exposed to Pesticides

open access: yesCells, 2019
Increased DNA damage and the propension to cancer development, depend on the modulation of the mechanisms to control and maintain genomic integrity. Poly(ADP-Ribose)Polymerase activation and automodification are early responses to genotoxic stress.
