Presenilin-ryanodine receptor connection [PDF]

Proceedings of the National Academy of Sciences, 2013
The Presenilins (PS) gene family is composed of two members: PS1 and PS2. Mutations in PSs are linked to familial Alzheimer's disease (FAD) (1). PSs are the catalytic subunits of the γ-secretase multimolecular complex, which mediates the intramembranous cleavage of many type I membrane proteins, including amyloid precursor protein (APP) and Notch (2, 3)

The ryanodine receptor microdomain in cardiomyocytes

Cell Calcium, 2023
The ryanodine receptor type 2 (RyR) is a key player in Ca2+ handling during excitation-contraction coupling. During each heartbeat, RyR channels are responsible for linking the action potential with the contractile machinery of the cardiomyocyte by releasing Ca2+ from the sarcoplasmic reticulum.

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

Advanced 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.

Calmodulin-binding Locations on the Skeletal and Cardiac Ryanodine Receptors*

Journal of Biological Chemistry, 2012
Background: Ca2+-calmodulin (CaM) and apo-CaM regulate ryanodine receptors (RyRs) differently. Results: Mutant and wild-type CaM-binding locations on RyRs have been determined.

Regulation of Ryanodine Receptors in the Heart [PDF]

Circulation Research, 2007
See related article, pages 819–829 In response to exercise or other stresses, catecholamines are released into the circulation and within the heart. Catecholaminergic stimulation of β1-adrenergic receptors (β1ARs) in the heart increases heart rate (chronotropy) and contractility (inotropy), resulting in increased cardiac output during acute ...

Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

ESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...

Aging Effects of Caenorhabditis elegans Ryanodine Receptor Variants Corresponding to Human Myopathic Mutations

G3: Genes, Genomes, Genetics, 2017
Delaying the decline in skeletal muscle function will be critical to better maintenance of an active lifestyle in old age. The skeletal muscle ryanodine receptor, the major intracellular membrane channel through which calcium ions pass to elicit muscle ...

Ryanodine receptors blockade reduces Amyloid-beta load and memory impairments in Tg2576 mouse model of Alzheimer disease

Journal of Neuroscience, 2012
In Alzheimer disease (AD), the perturbation of the endoplasmic reticulum (ER) calcium (Ca2+) homeostasis has been linked to presenilins, the catalytic core in γ-secretase complexes cleaving the amyloid precursor protein (APP), thereby generating amyloid ...
