In this work we have combined biochemical and electrophysiological approaches to explore the modulation of rat ventricular transient outward K(+) current (I(to)) by calmodulin kinase II (CaMKII). Intracellular application of CaMKII inhibitors KN93, calmidazolium, and autocamtide-2-related inhibitory peptide II (ARIP-II) accelerated the inactivation of(More)
Imipramine, mianserine and maprotiline are three widely used antidepressant drugs with different chemical structure. In the present work we have studied the effects of these drugs on the delayed rectifier potassium current (I(K)) in myocytes isolated from rat ventricle. The delayed rectifier potassium current, responsible for action potential termination,(More)
Over the last years zebrafish has become a popular model in the study of cardiac physiology, pathology and pharmacology. Recently, the application of the 3Rs regulation and the characteristics of the embryo have reduced the use of adult zebrafish use in many studies. However, the zebrafish embryo cardiac physiology is poorly characterized since most works(More)
The heart must constantly adapt its activity to the needs of the body. In any potentially dangerous or physically demanding situation the activated sympathetic nervous system leads a very fast cardiac response. Under these circumstances, α1-adrenergic receptors activate intracellular signaling pathways that finally phosphorylate the caveolae-located(More)
