Herg channel current

WitrynaIntroduction: Safety Pharmacology studies were conducted in mouse, rat, and non-human primate to determine in vivo effects of antisense oligonucleotides (ASOs) on … WitrynahERG activity manifests as the movement of potassium ions through a pore present in the hERG channel protein. In the heart, that potassium movement generates one of the major repolarizing currents that bring the excited cardiomyocyte to rest. Any impairment of this repolarizing current may result in life-threatening cardiac arrhythmias.
