blockade of the human ether-a-go-go-related gene (hERG) encoded rapidly activating delayed rectifier potassium (IKr) of cardiac cells
<h3>What are human ether-a-go-go-related gene (hERG)?</h3>
The rapidly activating delayed rectifier potassium channel's pore-forming component is encoded by the human ether-a-go-go-related gene (hERG) (IKr).
Acquired long-QT syndrome, which puts people at risk for ventricular arrhythmias and sudden death, is mostly caused by drug- or illness-mediated alteration of hERG activity.
Abuse and fatality rates related to fentanyl have been on the rise recently, raising severe health concerns.
We looked into how fentanyl affects the hERG channel because it frequently results in abrupt death.
We also looked at the effects of norfentanyl, the primary metabolite, and naloxone, an antidote for fentanyl overdose. HEK293 cell currents of hERG channels that were persistently expressed were captured using the whole-cell voltage-clamp technique.
