The apicobasal dispersion of ventricular repolarization in humans is associated with age and affects arrhythmia vulnerability

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated the age‐ and sex‐related differences in the apicobasal repolarization gradient (ABRG) and evaluated their possible role inventricular arrhythmia vulnerability. Electrocardiographic imaging (ECGI) was performed in healthy subjects during sinus rhythm, and the average recovery time (RT) and activation–recovery ...

Ro5‐4864, a ligand of the mitochondrial translocator protein, protects against heart failure in mice via regulation of the p62‐Keap1‐Nrf2 axis

The Journal of Physiology, EarlyView.
Abstract figure legend Graphical abstract of the proposed Ro5‐4864 mechanism of action via p62‐Keap1‐Nrf2 axis in heart failure. TSPO, the 18‐kDa mitochondrial translocator protein of the outer mitochondrial membrane, can directly interact with p62 (also known as SQSTM1), which is crucial for the degradation of damaged mitochondria by autophagy ...

Electromechanical modelling and simulation of human‐induced pluripotent stem cell‐derived cardiomyocytes predict drug‐induced contractility effects

The Journal of Physiology, EarlyView.
Abstract figure legend A study described in this paper describes a new tool for hiPSC‐CM electromechanical behaviour simulations using mathematical modelling. The model enables in silico assays making drug testing quick, comprehensive and accurate. New hiPSC‐CM models can be used as a platform to integrate in vitro and in silico findings.

In silico predictions of action potential propagation in doxorubicin cardiotoxicity: A parametric study using preclinical 3D magnetic resonance imaging‐based fibrotic left ventricle models

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).
