The aim of the present study was to investigate the role of calcineurin in the down-regulation of left ventricular transmural voltage-dependent K+ currents in heart failure. Transverse aorta was banded by using microsurgical techniques to create mouse heart failure model. Sham-operated(Sham) or aorta banded(Band) mice were randomized to receive calcineurin inhibitor cyclosporine A(Cs A) or vehicle. The densities and kinetic properties of voltage-dependent K+ currents, as well as action potential(AP), of lef...
