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.

Hydroxymethylation of microRNA-365-3p Regulates Nociceptive Behaviors via Kcnh2 [PDF]

The Journal of Neuroscience, 2016
DNA 5-hydroxylmethylcytosine (5hmC) catalyzed by ten-eleven translocation methylcytosine dioxygenase (TET) occurs abundantly in neurons of mammals. However, thein vivocausal link between TET dysregulation and nociceptive modulation has not been established.

Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin

The Journal of Physiology, EarlyView.
Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S.

Potassium voltage-gated channel subfamily H member 2 (KCNH2) is a promising target for incretin secretagogue therapies

Signal Transduction and Targeted Therapy
Derived from enteroendocrine cells (EECs), glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) are pivotal incretin hormones crucial for blood glucose regulation.

Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

The Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

Case Report: Biventricular Noncompaction Cardiomyopathy With Pulmonary Stenosis and Bradycardia in a Fetus With KCNH2 Mutation

Frontiers in Genetics, 2022
Background: Left ventricular noncompaction (LVNC) is a rare cardiomyopathy, long QT syndrome (LQTS) is a rare ion channel disease, and simultaneous occurrence of both is even rarer.

hERG1 channels and potential therapeutics for long QT syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...

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.

Optimization of novel compounds using computer‐aided drug design for treatment of cardiac arrhythmia

British Journal of Pharmacology, Volume 183, Issue 17, Page 5407-5420, September 2026.
Background and Purpose Loss‐of‐function mutations of the voltage‐gated Kv7.1 (KCNQ/KCNE1) channels lead to cardiac arrhythmia such as long QT syndrome, characterized by a prolonged QT interval . One strategy to correct the prolonged QT interval is to design molecules that activate KCNQ1/KCNE1 channels and restore the QT interval.
