Targeting potassium channels and autophagy to defeat chemoresistance

Molecular & Cellular Oncology, 2020
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 ...

Derivation and characterization of two human induced pluripotent stem cell lines (NUIGi004-A) and (NUIGi012-A) from two patients with LQT2 disease

Stem Cell Research, 2021
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 ...

Impact of functional studies on exome sequence variant interpretation in early-onset cardiac conduction system diseases [PDF]

, 2020
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.

The Linkage Phase of the Polymorphism KCNH2-K897T Influences the Electrophysiological Phenotype in hiPSC Models of LQT2

Frontiers in Physiology, 2021
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.

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.

Identification and Characterization of a Transcribed Distal Enhancer Involved in Cardiac Kcnh2 Regulation

Cell Reports, 2019
Summary: The human ether-a-go-go-related gene KCNH2 encodes the voltage-gated potassium channel underlying IKr, a current critical for the repolarization phase of the cardiac action potential. Mutations in KCNH2 that cause a reduction of the repolarizing

Generation of three heterozygous KCNH2 mutation-carrying human induced pluripotent stem cell lines for modeling LQT2 syndrome

Stem Cell Research, 2021
Congenital long QT syndrome type 2 (LQT2) results from KCNH2 mutations that cause loss of Kv11.1 channel function which can lead to arrhythmias, syncope, and sudden death.

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

, 2012
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 ...
