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 skeletal muscle ryanodine receptor interaction domain in triadin. [PDF]

PLoS ONE, 2012
Excitation-contraction coupling in skeletal muscle depends, in part, on a functional interaction between the ligand-gated ryanodine receptor (RyR1) and integral membrane protein Trisk 95, localized to the sarcoplasmic reticulum membrane.

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).

A Mechanism for Statin-Induced Susceptibility to Myopathy

JACC: Basic to Translational Science, 2019
Summary: This study aimed to identify a mechanism for statin-induced myopathy that explains its prevalence and selectivity for skeletal muscle, and to understand its interaction with moderate exercise.

ER proteostasis meets mitochondrial function: contact sites as hubs of communication and therapeutic targets

The FEBS Journal, EarlyView.
Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

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.

Long‐Term Serial Exercise Stress Testing in Catecholaminergic Polymorphic Ventricular Tachycardia on Beta‐Blocker and Flecainide Therapy

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Introduction Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially life‐threatening arrhythmic disorder typically treated with beta‐blockers and, occasionally, with flecainide. Methods All patients underwent genetic testing, electrocardiogram, echocardiogram, and exercise testing.

DIAGNOSTICATION OF MALIGNANT HYPERTHERMIA IN SWINE

Scientific Papers Animal Science and Biotechnologies, 2023
Malignant hyperthermia (MH) causes neurological, liver, and kidney damage and death in humans and major economic losses in the swine industry. A single point mutation in the gene for the skeletal muscle ryanodine receptor (Ryrl) was found to be ...

Applying lessons from limb muscle disuse and ageing to better understand ventilator‐induced diaphragm dysfunction

Experimental Physiology, EarlyView.
Abstract Mechanical ventilation (MV) is a life‐saving intervention applied to critically ill patients. A common consequence of MV is ventilator‐induced diaphragm dysfunction (VIDD), which is characterized by significant diaphragm atrophy and reduced contractile function. Older patients who receive MV are more likely to develop VIDD, have worse recovery,
