Modulation of energy homeostasis in maize and Arabidopsis to develop lines tolerant to drought, genotoxic and oxidative stresses [PDF]
, 2017 Abiotic stresses cause crop losses worldwide that reduce the average yield by more than 50%. Due to the high energy consumed to enhance the respiration rates, the excessive reactive oxygen species release provokes cell death and, ultimately, whole plant ...

Crystallographic and biochemical analysis of the mouse poly(ADP-ribose) glycohydrolase. [PDF]
PLoS ONE, 2014 Protein poly(ADP-ribosyl)ation (PARylation) regulates a number of important cellular processes. Poly(ADP-ribose) glycohydrolase (PARG) is the primary enzyme responsible for hydrolyzing the poly(ADP-ribose) (PAR) polymer in vivo.

Human PARP1 substrates and regulators of its catalytic activity: An updated overview
Frontiers in Pharmacology, 2023 Poly (ADP-ribose) polymerase 1 (PARP1) is a key DNA damage sensor that is recruited to damaged sites after DNA strand breaks to initiate DNA repair. This is achieved by catalyzing attachment of ADP-ribose moieties, which are donated from NAD+, on the ...

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

Molecular mechanism of poly(ADP-ribosyl)ation catalyzed by human poly(ADP-ribose) polymerase-1 [PDF]
, 2017 Human poly(ADP-ribose) polymerase-1 (PARP-1) is an abundant nuclear enzyme which catalyzes protein poly(ADP-ribosyl)ation upon binding to DNA. NAD+ is used as a co-substrate in the reaction via iterative transfer of its ADP-ribose moiety to acceptor ...

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

Rapamycin inhibits poly(ADP-ribosyl)ation in intact cells [PDF]
Biochemical and Biophysical Research Communications, 2009 Rapamycin is an immunosuppressive drug, which inhibits the mammalian target of rapamycin (mTOR) kinase activity inducing changes in cell proliferation. Synthesis of poly(ADP-ribose) (PAR) is an immediate cellular response to genotoxic stress catalyzed mostly by poly(ADP-ribose) polymerase 1 (PARP-1), which is also controlled by signaling pathways ...
