Epicardial Lineages and Cardiac Repair

Journal of Developmental Biology, 2013
The death of cardiac myocytes resulting from myocardial infarction is a major cause of heart failure worldwide. Effective therapies for regenerating lost cardiac myocytes are lacking.

Cyclic AMP-Dependent Regulation of Kv7 Voltage-Gated Potassium Channels

Frontiers in Physiology, 2020
Voltage-gated Kv7 potassium channels, encoded by KCNQ genes, have major physiological impacts cardiac myocytes, neurons, epithelial cells, and smooth muscle cells. Cyclic adenosine monophosphate (cAMP), a well-known intracellular secondary messenger, can

In silico modelling of multi‐electrode arrays for enhancing cardiac drug testing on hiPSC‐CM heterogeneous tissues

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the experimental and computational framework for investigating hiPSC‐CM electrophysiology with MEA systems. The MEA‐based model integrates experimental data with phenotype‐specific ionic models and tissue‐level heterogeneity.

TMEM16A channel signalling microdomains in the regulation of vascular function

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow

The Journal of Physiology, EarlyView.
Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

TRPV4 Activation during Guinea Pig Airway Smooth Muscle Contraction Promotes Ca²⁺ and Na⁺ Influx

Pharmaceuticals
Airway smooth muscle (ASM) contraction is determined by the increase in intracellular Ca2+ concentration ([Ca2+]i) caused by its release from the sarcoplasmic reticulum (SR) or by extracellular Ca2+ influx.

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

The Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...
