The ARumenamide AR-788 suppresses the transient outward current in human iPSC-derived right-ventricular Brugada cardioids

Brugada syndrome (BrS) is an inherited arrhythmia disorder with limited drug therapy, quinidine being the principal agent. Loss-of-function variants in SCN5A reduce the cardiac sodium current (INa), but the arrhythmogenic imbalance also depends on the transient outward potassium current (Ito). Here we generated human i...

Developmental mis-specification of cardiac conduction and structure transcriptome in Brugada syndrome

The findings support a model in which non-SCN5A BrS is associated with early dysregulation of developmental transcriptional networks controlling cardiac conduction and extracellular matrix organization, whereas SCN5A-mediated BrS primarily results from sodium channel deficiency with limited developmental remodeling.
