Reactive Oxygen Species Suppress Cardiac NaV1.5 Expression through Foxo1

Abstract excerpt

Na(V)1.5 is a cardiac voltage-gated Na(+) channel αsubunit and is encoded by the SCN5a gene. The activity of this channel determines cardiac depolarization and electrical conduction. Channel defects, including mutations and decrease of channel protein levels, have been linked to the development of cardiac arrhythmias. The molecular mechanisms underlying the regulation of Na(V)1.5 expression are largely unknown....
