MECHANISMS OF DISEASE Acute Oxygen-Sensing Mechanisms [PDF]

, 2005
JOSEPH PRIESTLEY, ONE OF THE THREE SCIENTISTS CREDITED WITH THE discovery of oxygen, described the death of mice that were deprived of oxygen. However, he was also well aware of the toxicity of too much oxygen, stating, “For as a candle burns much faster

Precision Editing of NLRS Improves Effector Recognition for Enhanced Disease Resistance

Advanced Science, EarlyView.
Precision engineering of plant NLR immune receptors enables rational design of enhanced pathogen resistance through mismatched pairing, domain swapping, and targeted mutagenesis. These approaches achieve multi‐fold expansion in recognition breadth while minimizing autoimmunity risks and fitness penalties.

Regulation of Renin Release via Cyclic ADP-Ribose-Mediated Signaling: Evidence from Mice Lacking CD38 Gene

Cellular Physiology and Biochemistry, 2013
Background/Aims: Despite extensive studies, the intracellular regulatory mechanism of renin production and release is still poorly understood. The present study was designed to test whether CD38-ADP-ribosylcyclase signaling pathway contributes to the ...

Genetic Ablation of CD38 Protects against Western Diet-Induced Exercise Intolerance and Metabolic Inflexibility. [PDF]

PLoS ONE, 2015
Nicotinamide adenine dinucleotide (NAD+) is a key cofactor required for essential metabolic oxidation-reduction reactions. It also regulates various cellular activities, including gene expression, signaling, DNA repair and calcium homeostasis ...

Cyclic ADP-Ribose and Calcium Signaling in Eggs

Neurosignals, 1996
Cyclic ADP-ribose is a cyclic nucleotide with Ca2+ signaling functions. It was first discovered in sea urchin eggs and has since been shown to be active in a variety of cells. Another Ca2+ release mechanism recently described in the eggs is mediated by nicotinic acid dinucleotide phosphate, a derivative of NADP+. This article summarizes current results

Poly(ADP-ribose) Polymerase-1 (PARP1) in Atherosclerosis: From Molecular Mechanisms to Therapeutic Potential [PDF]

, 2014
Poly(ADP-ribosyl)ation reactions, carried out by poly(ADP-ribose) polymerases (PARPs/ARTDs), are reversible posttranslational modifications impacting on numerous cellular processes (e.g., DNA repair, transcription, metabolism, or immune functions). PARP1

Spatio‐Temporal Proteomic Landscape Reveals Early Warning Signals of Esophageal Squamous Cell Carcinoma Progression

Advanced Science, EarlyView.
This study constructs a proteomic atlas of esophageal squamous cell carcinoma (ESCC) progression using esophageal biopsy samples. It identifies moderate dysplasia as the critical turning stage and a seven‐protein panel for early detection. Functionally, GBP6 loss promotes ESCC progression via cell cycle and epithelial‐mesenchymal transition (EMT ...

Characterization of Two-Pore Channel 2 by Nuclear Membrane Electrophysiology [PDF]

, 2016
Lysosomal calcium (Ca2+) release mediated by NAADP triggers signalling cascades that regulate many cellular processes. The identification of two-pore channel 2 (TPC2) as the NAADP receptor advances our understanding of lysosomal Ca2+ signalling, yet the ...

Synthesis of Bispecific Conjugates by ADP‐Ribosyl Cyclases

Advanced Science, EarlyView.
Genetic fusion of a CD38 enzymatic domain to antibody scaffolds allows site‐specific conjugation of small‐molecule ligands. Using this approach, a PSMA ligand DUPA is conjugated with an anti‐human CD3 Fab antibody. The resulting bispecific anti‐CD3‐DUPA conjugate facilitates recruitment and activation of cytotoxic T cells against PSMA‐expressing ...

Molecular mechanism and functional role of brefeldin A-mediated ADP-ribosylation of CtBP1/BARS [PDF]

, 2015
ADP-ribosylation is a posttranslational modification that modulates the functions of many target proteins. We previously showed that the fungal toxin brefeldin A (BFA) induces the ADP-ribosylation of C-terminal-binding protein-1 short-form/BFA-ADP ...
