Single nuclei RNA-seq and snATAC-seq multiome performed in WT and Dhx36 conditional KO hearts at postnatal day 7 (PD7)

In these experiments, we aimed to investigate the role of cardiomyocyte-specific deletion of the G-quadruplex resolvase Dhx36 in heart development and cardiomyocyte differentiation. To achieve this, we conducted multi-omics analysis using single-nuclei RNA sequencing (RNA-seq) and ATAC sequencing (ATAC-seq) on hearts from postnatal day 7 (PD7) wild-type (WT) and Dhx36 conditional knockout (cKO) mice. Our findings reveal that Dhx36 plays a critical role in the development of the cardiac conduction system (CCS) and in the differentiation of both CCS and working cardiomyocytes
