Jervell and Lange‐Nielsen Syndrome Related Clinical Genetics and Experimental Models

Pediatric Discovery, EarlyView.
ABSTRACT Jervell and Lange‐Nielsen syndrome (JLNS) is defined by electrocardiographic QT prolongation and sensorineural hearing loss, caused by homozygous or compound heterozygous variants in KCNQ1 and/or KCNE1. KCNQ1 encodes the alpha subunit Kv7.1 of the ion channels accountable for slow delayed rectifier potassium currents (IKs), whereas KCNE1 ...

Variable electrophysiology before and after block of the two delayed rectifier potassium channels in groups of isolated rabbit ventricular cells

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Between‐cell differences in ventricular cardiomyocyte action potential duration (APD) and responses to ion channel block may contribute to pro‐arrhythmic dispersion of myocardial repolarisation. This study quantifies between‐cell physiological and pharmacological variability in the rabbit left ventricle (LV) and uses ...

Therapeutic potential of small molecules that block receptor‐induced Kv7/M‐current suppression in neuroprotection, seizures, and pain

British Journal of Pharmacology, EarlyView.
Receptor‐induced Kv7/M‐current suppression increases neuronal activity and contributes to pathology of several conditions. A new class of Kv7 modulators identified in this study attenuates M‐current suppression and shows therapeutic effects. Abstract Background and Purpose Neuronal Kv7 channels generate low voltage–gated potassium currents known as the

Flecainide binding dynamics in voltage‐gated sodium channels: A comparative isoform analysis of the state‐dependent block

British Journal of Pharmacology, EarlyView.
Background and Purpose Local anaesthetics and class I anti‐arrhythmic drugs block voltage‐gated Na+ channels, but the molecular basis for the isoform differences in drug sensitivity remains unclear. Understanding these mechanisms is essential for optimizing therapeutic efficacy and safety.

Cardiotoxicity of BRAF/MEK inhibitors

British Journal of Pharmacology, EarlyView.
Abstract Rapidly accelerated fibrosarcoma type B/B‐Raf proto‐oncogene, serine/threonine kinase (BRAF) and mitogen‐activated protein kinase (MEK) inhibitors have transformed outcomes in cancer therapy, particularly in melanoma. However, cardiovascular toxicities are increasingly recognized in real‐world clinical practice.

Diltiazem N‐oxide, a novel ischaemia‐activated prodrug, prevents ischaemia‐induced ventricular fibrillation without off‐target adverse effects

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ventricular fibrillation (VF) in coronary heart disease accounts for up to 70% of sudden cardiac death. We examined whether diltiazem N‐oxide (DNO) has ischaemia‐selective antiarrhythmic activity. Experimental Approach Randomised and blinded experiments were performed in rat isolated hearts and in anaesthetised rats to ...

Characterization of AV Nodal Left Inferior Extension by Use of High‐Density Mapping and Voltage‐Time Relationship

Journal of Cardiovascular Electrophysiology, EarlyView.
High resolution voltage LA map is shown with Ripple mapping during sinus rhythm prior to atrial fibrillation ablation (panel A‐D, top row Left Anterior Oblique view, bottom row Left Anterior Oblique Caudal view). Chamber activation is visualized by white Ripple bars, proceeding from the septum and septal roof (panel A), spreading clockwise and ...
