The sodium current is primarily carried by the voltage gated sodium channel isoform NaV1.5. Using a novel NaV1.5 chimeric construct (NaV1.5-GX), our study reveals a unique chamber-specific distribution of non-NaV1.5 sodium channel isoforms, and we performed bulk RNA sequencing of murine ventricles to assess if acute NaV1.5 inhibition changed the trascriptional profile of the ventricular myocytes.2026/04/09GSE319426GSM9517837GSM9517826GSM9517825GSM9517836GSM9517828GSM9517827GSM9517829GSM9517831GSM9517830GSM9517833GSM9517832GSM9517835GSM9517824GSM951783424247319426Mus musculus[41878815]
