The aim of our study was to create an in vitro `patient-specific cell-based system’ that could facilitate the screening of new therapeutic molecules for the treatment of catecholaminergic polymorphic ventricular tachycardia (CPVT), an inherited kind of fatal arrhythmia. Here, we report the development of a cardiac model of CPVT by way of the generation of iPSC from a CPVT patient carrying a heterozygous mutation in the cardiac ryanodine receptor gene (RyR2) and their subsequent differentiation into cardiomyocytes (CMs). Whole-cell patch-clamp and intracellular MEK5 Inhibitor Compound electrical recordings of spontaneously beating cells revealed the presence of delayed afterdepolarizations (DADs) in CPVT-CMs, both in resting conditions and after b-adrenergic stimulation, resembling the cardiac phenotype of your individuals. Furthermore, therapy with KN-93 (2-[N-(2-hydroxyethyl)]-N-(4methoxybenzenesulfonyl)]amino-N-(4-chlorocinnamyl)-N-methylbenzylamine), an antiarrhythmic drug that inhibits Ca2 ?/calmodulin-dependent serine hreonine protein kinase II (CaMKII), drastically lowered the presence of DADs in CVPT-CMs, rescuing the arrhythmic phenotype induced by catecholamine.
