The sodium current is primarily carried by the voltage gated sodium channel isoform NaV1.5. Using a novel NaV1.5 chimeric construct, our study reveals a unique chamber-specific distribution of non-NaV1.5 sodium channel isoforms, and we performed spatial sequencing of murine hearts to assess the transcriptional changes associated with our chimeric channel.2026/04/09GSE319481GSM9518461GSM9518460GSM9518462GSM9518458GSM9518457GSM951845934290319481Mus musculus[41878815]
