The KCNH2 genetic polymorphism (1956, C>T) is a novel biomarker that is associated with CCB and α,β-ADR blocker response in EH patients in China. [PDF]
KCNH2 (hERG) potassium channels have an integral role in regulating the excitability of smooth muscle cells. Some pathways driven by angiotensin II, nitric oxide and adrenergic receptors blocker are involved in modulating the properties of KCNH2 ...

Long QT syndrome type 2 (LQT2) is associated with KCNH2, which encodes the α subunit of the ion channel that controls the K+ current in the heart. Mutations of KCNH2 cause loss of Kv11.1 channel function by disrupting subunit folding, assembly, or ...

Targeting potassium channels and autophagy to defeat chemoresistance
Both autophagy and hERG1 potassium channels have been shown to promote tumor progression and resistance to treatment. Our findings indicate that the antibiotic clarithromycin can target hERG1 and modulate autophagy to promote the death of chemoresistant ...

While rare mutations in ion channel genes are primarily responsible for inherited cardiac arrhythmias, common genetic variants are also an important contributor to the clinical heterogeneity observed among mutation carriers.

Impact of functional studies on exome sequence variant interpretation in early-onset cardiac conduction system diseases [PDF]
Aims The genetic cause of cardiac conduction system disease (CCSD) has not been fully elucidated. Whole-exome sequencing (WES) can detect various genetic variants; however, the identification of pathogenic variants remains a challenge.

Postpartum QT Prolongation in a Long QT Syndrome Type 1 Patient. [PDF]
We present the case of an LQT1 patient with a previous cardiac event during the postpartum period. Performance of electrocardiograms and Estradiol as well as Progesterone levels revealed prolonged QT intervals postpartum correlating to declining sex hormone levels elevate the risk for arrhythmic events in this period.

Sudden cardiac death in young athletes: Literature review of molecular basis [PDF]
Intense athletic training and competition can rarely result in sudden cardiac death (SCD). Despite the introduction of pre-participation cardiovascular screening, especially among young competitive athletes, sport-related SCD remains a debated issue ...
