Project description:The goal is to find out the gene expression changes when Dicer was inactivated in the murine heart. Keywords: Dicer mutant Dicer gene was specifically inactivated in the mouse heart using cardiac specific Nkx2.5 Cre knock-in line. Embryonic day 11.5 heart from mutant and control hearts were compared in triplicates.

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.

Project description:Anterior Heart Field (AHF)-conditional Mef2c Knockout
| PRJNA281945 | ENA
Project description:We have shown that Chrnb4-cre; Dicerflox/flox retinas (Dicer CKO) display a cone dystrophy by postnatal day P21, independent of rod degeneration. To elucidate which gene pathways were affected by Dicer loss, RNA sequencing was performed in whole neural retinas of P21 control and Dicer CKO mice. This experiment aims to identify which genes were differentially expressed between Dicer conditional knockout and control mice.

Project description:To determine the temporal variation of mRNA levels, we collected and sequenced poly-adenylated RNA from all cell extracts, cytoplasmic and nuclear fractions of a conditional Dicer mutant [DTCM23/49 XY (Nesterova et al. 2008)] mouse Embryonic Stem Cells before induction of Dicer excision (day 0) and at days 4, 8, 10 and 12 following Dicer loss of function. coverage.

Project description:MicroRNAs (miRNAs) are small, endogenous, non-protein coding RNAs that are an important means of post-transcriptional gene regulation. Deletion of Dicer, a key miRNA processing enzyme, is embryonic lethal in mice, and tissue-specific Dicer deletion results in developmental defects. Using a conditional knockout model, we generated mice lacking Dicer in the adrenal cortex. These Dicer knockout (KO) mice exhibited perinatal mortality and failure of the adrenal cortex during late gestation between embryonic day 16.5 (E16.5) and E18.5. Further study of Dicer KO adrenals demonstrated a significant loss of Sf1 expressing cortical cells that was histologically evident as early as E16.5 coincident with an increase in p21 and cleaved-caspase 3 staining in the cortex. However, peripheral cortical proliferation persisted in KO adrenals as assessed by anti-PCNA staining. To further characterize the embryonic adrenals from Dicer KO mice, we performed microarray analyses for both gene expression and miRNA on purified RNA isolated from control and KO adrenals of E15.5 and E16.5 embryos. Consistent with the absence of Dicer and the associated loss of miRNA-mediated mRNA degradation, we observed an up-regulation of a small subset of adrenal transcripts in Dicer KO mice, most notably the transcripts coded by the genes Nr6a1 and Acvr1c. Indeed, several miRNAs, including let-7, miR-34c, and miR-21 that are predicted to target these genes for degradation, were also markedly down-regulated in Dicer KO adrenals. Together these data suggest a role for miRNA mediated regulation of a subset of genes that are essential for normal adrenal growth and homeostasis. Adrenals from control and Dicer KO litter mates were pooled separately from 4 individual litters, resulting in a total of 4 control (cre-) and 4 Dicer KO biological replicates at both E15.5 and E16.5.
