WebNov 15, 1996 · A hypothesis is that HERG produces the repolarizing cardiac potassium current I Kr, with the consequence that mutations in HERG prolong the QT interval by reducing I Kr. The elementary properties of HERG are unknown, and as a test of the hypothesis that HERG produces I Kr, we compared their elementary properties.

WebJul 25, 2024 · In cardiomyocytes, human ether-a-go-go related gene ( hERG) encoded potassium channels mediate delayed rectifier potassium current, which is the most important mechanism for drug-induced prolongation of QT. Due to its special molecular structure, and the hERG can be a variety of structural compounds to suppress. WebHuman ether-a-go-go-related gene (hERG) channel blockade by small molecules is a big concern during drug development in the pharmaceutical industry. Failure or inhibition of hERG channel activity caused by drug molecules can lead to prolonging QT interval, which will result in serious cardiotoxicity. chingford rise estate

WebHuman ether-a-go-go-related gene (hERG) potassium channels conduct the rapid component of the delayed rectifier potassium current, IKr, which is crucial for repolarization of cardiac action potentials. Moderate hERG blockade may produce a beneficial class III antiarrhythmic effect. WebIn this study they evaluated the ability of an in silico action potential simulation assay, which uses concentration–effect data from high-throughput ion channel screens (hERG, NaV1.5, CaV1.2), to predict the results of the rabbit left-ventricular wedge assay. WebThe hERG channel inhibition assay is a highly sensitive measurement which will identify compounds exhibiting cardiotoxicity related to hERG inhibition in vivo. It is important to note, however that not all compounds … chingford road closure
