AIMS The aim of this study was to analyse the mRNA expression levels and protein distribution of the cardiac sodium channel Scn5a/Nav1.5 during mouse cardiogenesis. METHODS AND RESULTS Scn5a mRNA levels were determined by real-time RT-PCR using embryonic hearts ranging from E9.5 to E17.5 as well as postnatal and adult hearts. In addition, Scn5a protein(More)
AIMS Ion channel remodelling and ventricular conduction system (VCS) alterations play relevant roles in the generation of cardiac arrhythmias, but the interaction between ion channel remodelling and cardiac conduction system dysfunctions in an arrhythmogenic context remain unexplored. METHODS AND RESULTS We have used a transgenic mouse line previously(More)
The cardiac conduction system (CCS) is composed of a group of myocardial tissues that control and coordinate the heart. Alterations in the CCS - especially in the His-Purkinje system, have been identified as a major cause of lethal arrhythmias. Unstable arrhythmias secondary to channelopathies significantly increase the risk of sudden cardiac death (SCD).(More)
