Cyclic ADP-ribose. A new component of calcium signaling.

open access: yes, 1995
International audienceCyclic ADP-ribose is a recently discovered metabolite of NAD that appears to function in cellular calcium signaling. The discovery that NAD glycohydrolases are bifunctional enzymes that catalyze both the synthesis and hydrolysis of ...

Cyclic ADP-Ribose Requires FK506-Binding Protein to Regulate Intracellular Ca2+ Dynamics and Catecholamine Release in Acetylcholine-Stimulated Bovine Adrenal Chromaffin Cells

open access: yesJournal of Pharmacological Sciences, 2006
.: The present study was undertaken to elucidate whether cyclic ADP-ribose (cADPR) mediates the amplification of Ca2+ signaling and catecholamine release via the involvement of FK506-binding proteins (FKBPs)/ryanodine receptor (RyR) in bovine adrenal ...

Insights into the mechanism of bovine CD38/NAD+glycohydrolase from the X-ray structures of its Michaelis complex and covalently-trapped intermediates. [PDF]

open access: yesPLoS ONE, 2012
Bovine CD38/NAD(+)glycohydrolase (bCD38) catalyses the hydrolysis of NAD(+) into nicotinamide and ADP-ribose and the formation of cyclic ADP-ribose (cADPR).

TPI1 Loss Triggers a Metabolite‐Driven Mitochondrial Redox Vulnerability via the SARM1–cADPR–Ca2+ Axis

open access: yesAdvanced Science, EarlyView.
Metabolite‐driven redox stress governs cancer cell senescence. TPI1 deficiency elevates DHAP, initiating SARM1‐dependent cADPR‐Ca2+ release. Mitochondrial ROS surge subsequently induces DNA damage and senescence, offering a conserved therapeutic target in multiple cancers.

RIOX1-demethylated cGAS regulates ionizing radiation-elicited DNA repair

open access: yesBone Research, 2022
Exposure to radiation causes DNA damage; hence, continuous surveillance and timely DNA repair are important for genome stability. Epigenetic modifications alter the chromatin architecture, thereby affecting the efficiency of DNA repair.

EDNRA Forms a Positive Feedback Loop with the Hippo/YAP Axis to Drive Triple‐Negative Breast Cancer Progression

open access: yesAdvanced Science, EarlyView.
Endothelin receptor type A (EDNRA) and the Hippo/YAP pathway form a self‐reinforcing loop that sustains triple‐negative breast cancer. EDNRA activates YAP through Gαq/11–Rho/ROCK–LATS signaling, while YAP/TEAD4 reciprocally drives EDNRA transcription.

Imeglimin amplifies glucose-stimulated insulin release from diabetic islets via a distinct mechanism of action.

open access: yesPLoS ONE, 2021
Pancreatic islet β-cell dysfunction is characterized by defective glucose-stimulated insulin secretion (GSIS) and is a predominant component of the pathophysiology of diabetes.

PARP Inhibitors plus Anlotinib as Bridging Therapy for Armored CAR‐T Cells in Ovarian Cancer Enhances Infiltration and Antitumor Efficacy

open access: yesAdvanced Science, EarlyView.
This study shows that a PARP inhibitor combined with anlotinib, administered as bridging therapy, preconditions the tumor microenvironment to enhance the infiltration and antitumor activity of subsequently infused CAR‐T cells across preclinical ovarian cancer models, supporting bridging therapy as a promising strategy to address limited CAR‐T cell ...

Klotho‐Derived Peptide 1 Protects against Acute Kidney Injury by Directly Targeting Mitochondrial ATAD3A

open access: yesAdvanced Science, EarlyView.
This study uncovers that KP1, a Klotho‐derived peptide, protects the kidney against acute kidney injury, a clinical syndrome with high morbidity and mortality. KP1 enters tubular epithelial cells via endocytosis, directly interacts with the mitochondrial ATAD3A/HIGD2A complex, thereby preventing cytochrome c release, and caspases activation, and ...
