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

The 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.

14‐3‐3 proteins: Regulators of cardiac excitation–contraction coupling and stress responses

The Journal of Physiology, EarlyView.
Abstract figure legend 14‐3‐3 protein interactions in cardiac regulation. Schematic representation of 14‐3‐3 binding partners in excitation–contraction coupling, transcriptional regulation/development and stress response pathways. Asterisks indicate targets where the exact 14‐3‐3 binding site is unknown.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Cardioprotective effect of spirulina on cafeteria diet‐induced cardiac injury in silico and in vivo study

Journal of the Science of Food and Agriculture, Volume 106, Issue 8, Page 4720-4743, June 2026.
Abstract BACKGROUND Obesity is a major risk factor for cardiovascular disease, primarily due to its effects on lipid metabolism, oxidative stress, and inflammation. The aim of this study was to evaluate the effects of spirulina (SP) on cafeteria diet (CD)‐induced myocardial oxidative stress and inflammation using biochemical, histological, and in ...

Validation of a [3H]Astemizole Binding Assay in HEK293 Cells Expressing HERG K+ Channels

Journal of Pharmacological Sciences, 2004
A radioligand binding assay for the HERG (human ether-a-go-go-related gene) K+ channel was developed to identify compounds which may have inhibitory activity and potential cardiotoxicity.

Ion channels: structural basis for function and disease. [PDF]

, 1996
Ion channels are ubiquitous proteins that mediate nervous and muscular function, rapid transmembrane signaling events, and ionic and fluid balance. The cloning of genes encoding ion channels has led to major strides in understanding the mechanistic basis

Antidepressive and anxiolytic effects of ostruthin, a TREK-1 channel activator [PDF]

, 2018
We screened a library of botanical compounds purified from plants of Vietnam for modulators of the activity of a two-pore domain K+ channel, TREK-1, and we identified a hydroxycoumarin-related compound, ostruthin, as an activator of this channel ...

Activation of TREK‐1 and TREK‐2 Two‐Pore Domain Potassium Channels by the Kv4 Channel Modulator, NS5806

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT NS5806 is a diaryl‐urea small molecule developed for the treatment of pain and neurological disorders. A potent activator of Kv4.3 potassium channels, it is widely used to study Kv4 channel physiology in excitable cells, including trigeminal neurons.

CardioGenAI: a machine learning-based framework for re-engineering drugs for reduced hERG liability

Journal of Cheminformatics
The link between in vitro hERG ion channel inhibition and subsequent in vivo QT interval prolongation, a critical risk factor for the development of arrythmias such as Torsade de Pointes, is so well established that in vitro hERG activity alone is often ...

Silencing the Mutant KCNH2 Allele to Reduce the Effects of Long QT Syndrome Type 2

Frontiers in Bioscience-Landmark
Background: Long-QT syndrome type 2 (LQTS2), which is associated with life-threatening cardiac arrhythmias, is caused by pathogenic heterozygous loss-of-function mutations in the KCNH2 gene.
