Project description: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

Project description:Genome-wide transcriptomic analyses in left ventricles (LVs) from cardiac-specific miR-150 conditional knockout KO (cKO) mice were performed to identify novel miR-150 targets in the heart.
Project description:We used Illumina Small RNA and RNA-Seq kits to prepare both small RNA and RNA-Seq libraries from total RNA isolated from either leptotenze/zygotene or pachytene spermatocytes purified from either Dgcr8 or Dicer germline conditional knockout mice. Conditional knockout mice were generated by using a Ddx4 promoter to drive cre excision of either Dgcr8 or Dicer at embryonic day 18. Mixed leptotene/zygotene or pachytene spermatocytes were then isolated from the testis of adult conditional knockout mice, along with paired WT littermates as a control. RNA was isolated from these spermatocytes using Trizol. Small RNA or RNA-Seq libraries were then prepped using Illumina's sequencing library preparation kits.
