Abstract
After transient transfection of an hNav1.4-L443C/A444W mutant clone, HEK-293 cells exhibited large inactivation-deficient Na+currents. We subsequently established a stable cell line expressing robust inactivation-deficient Na+currents. Persistent late Na+currents were far more sensitive to block by class 1 anti-arrhythmic flecainide, mexiletine, propafenone, and amiodarone at 10 microM than peak Na+currents. Such results support a hypothesis...
