Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Ryanodine receptor in heart failure: potential therapeutic sites. [PDF]

Revista Cubana de Cardiología y Cirugía Cardiovascular, 2010
Heart failure (HF) is one of the most important contributors to morbidity and mortality from cardiac diseases. Ca2+ handling abnormalities play an important role in the development of HF.

AIP limits neurotransmitter release by inhibiting calcium bursts from the ryanodine receptor

Nature Communications, 2017
In this work the authors show that AIP (aryl hydrocarbon receptor-interacting protein), a gene frequently mutated in association with pituitary tumors, regulates neurotransmitter release by inhibiting calcium release from ryanodine receptors.

Structure of a mammalian ryanodine receptor [PDF]

Nature, 2014
Ryanodine receptors (RyRs) mediate the rapid release of calcium (Ca(2+)) from intracellular stores into the cytosol, which is essential for numerous cellular functions including excitation-contraction coupling in muscle. Lack of sufficient structural detail has impeded understanding of RyR gating and regulation.

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.

Inhibition of late sodium current prevents pathological hyperactivation of calcium/calmodulin‐dependent protein kinase IIδ in a murine model of acute doxorubicin‐related cardiotoxicity

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Doxorubicin (DOX) is a highly effective anthracycline, whose clinical application for cancer is limited by cardiotoxicity. The mechanisms underlying doxorubicin‐induced toxic cardiomyopathy (DICM) involve electrophysiological remodelling with intracellular Na+ overload because of increased late INa and hyperactivation of

A novel RyR1-selective inhibitor prevents and rescues sudden death in mouse models of malignant hyperthermia and heat stroke

Nature Communications, 2021
Mutations in ryanodine receptor 1 (RyR1), a Ca2+ release channel in skeletal muscle, cause malignant hyperthermia (MH) and are involved in heat stroke. Here, the authors show that an oxolinic acid-derivative RyR1 inhibitor effectively prevents and treats

Bruton tyrosine kinase inhibitors and cardiovascular adverse events

British Journal of Pharmacology, EarlyView.
Abstract Bruton tyrosine kinase inhibitors (BTKi) have transformed the management of chronic lymphocytic leukaemia and other B‐cell malignancies, yet their therapeutic benefit is tempered by clinically relevant cardiovascular toxicities (predominantly atrial fibrillation, hypertension, bleeding and ventricular arrhythmias).

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)
