Investigation of the Influence of hERG 1b on hERG Channel Pharmacology [PDF]

open access: yesBiophysical Journal, 2013
hERG channels mediating the rapid delayed rectifier K+ current (IKr) are important for normal ventricular repolarization. In native cardiac tissues, hERG 1a subunit co-assembles with a subunit encoded by an alternate transcript, “ERG1b” which has a shorter N-terminus (1) and influences current kinetics (2).

Proton block of proton-activated TRPV1 current. [PDF]

open access: yes, 2015
The TRPV1 cation channel is a polymodal nociceptor that is activated by heat and ligands such as capsaicin and is highly sensitive to changes in extracellular pH. In the body core, where temperature is usually stable and capsaicin is normally absent, H(+)

Prospective in silico trials identify combined SK and K2P channel block as an effective strategy for atrial fibrillation cardioversion

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In silico trials were conducted in 654 virtual patients with atrial fibrillation (AF) to assess the cardioversion efficacy of three pharmacological treatments: single SK and K2P channel block and combined SK+K2P channel inhibition. Left: representative virtual AF patient with the atria inside the torso.

Clenbuterol Attenuates hERG Channel by Promoting the Mature Channel Degradation [PDF]

open access: yesInternational Journal of Toxicology, 2017
Clenbuterol, a β2-selective adrenergic receptor agonist, is illicitly used in weight loss and performance enhancement and animal production. Increasing evidence demonstrates that clenbuterol induces various kinds of arrhythmias and QTc interval prolongation. However, little is known about the underlying mechanism.

Action potential clamp and pharmacology of the variant 1 Short QT Syndrome T618I hERG K⁺ channel.

open access: yesPLoS ONE, 2012
BackgroundThe familial Short QT Syndrome (SQTS) is associated with an increased risk of cardiac arrhythmia and sudden death. Gain-of-function mutations in the hERG K(+) channel protein have been linked to variant 1 of the SQTS. A hERG channel pore (T618I)

Fast stochastic simulation of biochemical reaction systems by\ud alternative formulations of the Chemical Langevin Equation [PDF]

open access: yes, 2010
The Chemical Langevin Equation (CLE), which is a stochastic differential equation (SDE) driven by a multidimensional Wiener process, acts as a bridge between the discrete Stochastic Simulation Algorithm and the deterministic reaction rate equation when ...

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical

Upregulation of Functional Kv11.1 Isoform Expression by Inhibition of Intronic Polyadenylation with Antisense Morpholino Oligonucleotides

open access: yes, 2014
The KCNH2 gene encodes the Kv11.1 potassium channel that conducts the rapidly activating delayed rectifier current in the heart. KCNH2 pre-mRNA undergoes alternative processing; intron 9 splicing leads to the formation of a functional, full-length Kv11 ...

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.
