Selective loss of Cx40 and conduction abnormalities underlie enhanced atrial fibrillation susceptibility in a HFpEF model in male mice

open access: yesPhysiological Reports, Volume 14, Issue 11, June 2026.
Abstract Heart failure with preserved ejection fraction (HFpEF) is frequently complicated by atrial fibrillation (AF), yet the mechanisms underlying AF vulnerability prior to or independent of extensive structural remodeling remain incompletely understood.

A Novel KCNJ2 Mutation Identified in an Autistic Proband Affects the Single Channel Properties of Kir2.1 [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2018
Inwardly rectifying potassium channels (Kir) have been historically associated to several cardiovascular disorders. In particular, loss-of-function mutations in the Kir2.1 channel have been reported in cases affected by Andersen-Tawil syndrome while gain-of-function mutations in the same channel cause the short QT3 syndrome.

Functional characterization of KCNJ2 mutations associated with Andersen-Tawil syndrome and atrial tachycardia

open access: yes, 2007
Andersen-Tawil syndrome is a triad of periodic paralysis, cardiac arrhythmias and dysmorphic features. The causative gene KCNJ2 encoding the Kir2.1 inward-rectifier potassium channel contributes to cell excitability and resting membrane potential in ...

The research of ion channel‐related gene polymorphisms with atrial fibrillation in the Chinese Han population

open access: yesMolecular Genetics & Genomic Medicine, 2019
Background Atrial fibrillation (AF) is one of the common arrhythmia in clinics. Its incidence is high among the elderly. This study aimed to identify a possible connection between ion channel‐related gene polymorphisms and the risk of AF. Methods A total

Population‐Based Study Found Low Risk of Misdiagnosing Long QT Syndrome as Breath‐Holding Spells in Swedish Children

open access: yesActa Paediatrica, Volume 115, Issue 5, Page 1116-1125, May 2026.
ABSTRACT Aim An electrocardiogram is commonly recommended in breath‐holding spell management, mainly to rule out long QT syndrome. This retrospective study investigated the risk of long QT syndrome being misdiagnosed as breath‐holding spells in a paediatric population in southern Sweden.

Opening closed inward rectifier potassium channel doors

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 10, Page 2197-2218, May 2026.
Inwardly rectifying potassium (KIR) channels are essential regulators of membrane potential in excitable and non‐excitable tissues. Although KIR channels exhibit a biophysical preference for potassium influx due to voltage‐dependent block of outward current by polyamines and Mg2+, under physiological conditions, they predominantly mediate K+ efflux ...

Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 16, 24 April 2026.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...
