Department of Molecular Biology and Pharmacology, Washington University School of Medicine, St Louis, MO 63110, USA
Circ Res 102:1406-15. 2008..Functional changes in repolarizing K(+) currents with LVH, therefore, result from distinct cellular (cardiomyocyte enlargement) and molecular (alterations in the numbers of functional channels) mechanisms...
Remodeling of excitation-contraction coupling in transgenic mice expressing ATP-insensitive sarcolemmal KATP channelsThomas P Flagg
Department of Cell Biology and Physiology, Washington University School of Medicine, St Louis, MO 63110, USA
Am J Physiol Heart Circ Physiol 286:H1361-9. 2004..Collectively, the data demonstrate that a compensatory increase in I(Ca) counteracts a mild activation of ATP-insensitive K(ATP) channels to maintain the action potential duration and elevate the inotropic state of TG hearts...
