Analysis of bone marrow-derived GMPs from Dicer1-deficient, C57BL/6 females. Dicer1 encodes an RNaseIII enzyme critical for miRNA biogenesis. Dicer1-deficient GMPs are defective in myeloid development in vitro. Results provide insight into the role of miRNAs in myeloid-lineage specification.

(Submitter supplied) MiRNAs have the potential to regulate cellular differentiation programs. However, miRNA-deficiency in primary hematopoietic stem cells (HSCs) results in HSC depletion in mice, leaving the question of whether miRNAs play a role in early-lineage decisions unanswered. To address this issue, we deleted Dicer1, which encodes an essential RNaseIII enzyme for miRNA biogenesis, in murine CCAAT/enhancer-binding protein alpha (C/EBPA)-positive myeloid-committed progenitors in vivo. more...

(Submitter supplied) Through gene expression analysis of CMPs and GMPs at single cell levels, we identified CD62L as a marker to reveal the heterogeneity of CMPs and GMPs. We confirmed that the CD62L-low CMPs represent ‘bona fide’ CMPs, whereas CD62L-high CMPs are mostly restricted to GMP potentials both in mice and humans. In addition, we identified CD62L-neg GMPs as the most immature subsets in GMPs and Ly6c+CD62L-low and Ly6c+CD62L-high GMPs are skewed to neutrophil and monocyte differentiation, respectively. more...

(Submitter supplied) Total bone marrow (BM) from miR-223 knockout (mir-223-/-) and wildtype (miR-223+/+) mice 21 was extracted, prestimulated for 2 days. Then, the BM cells were simultaneously cotransduced with MSCV-Hoxa9-pgk-neomycin and a MSCV-Meis1-IRES-YFP by co-cultivation with irradiated (4,000 cGy) viral producers. HoxA9-Meis1 transduced cells were sorted for YFP expression and continuously selected with neomycin (1.4 mg/ml). more...

(Submitter supplied) Recurrent somatic hotspot mutations of DICER1 appear to be clustered around each of four critical metal binding residues in the RNase IIIB domain of DICER1. This domain is responsible for cleavage of the 3’ end of the 5p-miRNA strand of a pre-mRNA hairpin. To investigate the effects of these cancer-associated “hotspot” mutations we engineered mouse Dicer1-deficient ES cells to express wild-type and an allelic series of the mutant human DICER1 variants. more...

(Submitter supplied) We report the generation and characterization of DICER1-deficient hESCs. We uncover an unexpected requirement for DICER1 as well as essential pro-survival roles of members of the mir-302- 367 and mir-371- 373 clusters in hESCs. Our work provides a robust platform for interrogating microRNA function in hESC and differentiation.

(Submitter supplied) Granulocyte-monocyte progenitors (GMPs) and monocyte-dendritic cell progenitors (MDPs) produce monocytes during homeostasis and in response to increased demand during infection. Both progenitor populations are thought to derive from common myeloid progenitors (CMPs), and a hierarchical relationship (CMP-GMP-MDP-monocyte) is presumed to underlie monocyte differentiation. Here, however, we demonstrate that mouse MDPs arose from CMPs independently of GMPs, and that GMPs and MDPs produced monocytes via similar, but distinct, monocyte-committed progenitors. more...

(Submitter supplied) DICER1 plays a critical role in microRNA (miRNA) biogenesis. Recurrent somatic “hotspot” mutations at four mental binding sites within the RNase IIIb domain of DICER1, were identified in ovarian sex cord-stromal tumors and have since been described in other pediatric tumors. In this study, we identified and characterized DICER1 hotspot mutations in endometrial cancers derived from The Cancer Genome Atlas (TCGA) and our local tumor bank. more...

(Submitter supplied) Endometrial cancer remains the most common gynecological malignancy in the United States. While the loss of the tumor suppressor, PTEN, is well studied in endometrial cancer, recent studies suggest that DICER1, the endoribonuclease responsible for miRNA genesis, also plays a significant role in endometrial adenocarcinoma. To examine the effects of DICER1 deletion on mRNA and miRNA expression in endometrial cancer, poly-A RNA sequencing (RNA-seq) and small RNA sequencing were performed. more...

(Submitter supplied) It has been shown previously that endothelial cells and LepR+ stromal cells are the main sources of SCF in vivo in the mouse bone marrow. We tested whether SCF from endothelial cells and/or LepR+ stromal cells is important for the maintenance of hematopoietic progenitors and erythroid progenitors in mouse bone marrow by conditional deletion of Scf from these two cell types. We discovered that Scf deletion from LepR+ stromal cells, but not endothelial cells, reduced the numbers of hematopoietic progenitors and erythroid progenitors in mice. more...

(Submitter supplied) In this study, we use pre-malignant cells from different Cebpa mutant acute myeloid leukemia (AML) models. We have used conditional KO models (CreLoxP) and isolated hematopoietic cells shortly after induction of recombination, in order to look at pre-leukemic cells, which have acquired the first hit, but not yet undergone full malignant transformation.

(Submitter supplied) To determine whether DGCR8 is required for maturation of all miRNAs, we performed miRNA microarray analysis. Using RNA from wild-type ES cells as our reference sample, we observed a global loss of miRNAs in DGCR8 knockout cells, but normal levels of expression in DGCR8 heterozygous cells. The similarity in expression levels between wild-type and heterozygous cells suggests that DGCR8 is not limiting in the maintenance of steady-state levels of miRNAs in ES cells. more...

(Submitter supplied) While most blood lineages are assumed to mature through a single cellular and developmental route downstream of hematopoietic stem cells (HSCs), dendritic cells (DCs) can be derived from both myeloid and lymphoid progenitors in vivo. To determine how distinct progenitors can generate similar downstream lineages, we examined the transcriptional changes that accompany loss of in vivo myeloid potential as common myeloid progenitors (CMPs) differentiate into common dendritic cell progenitors (CDPs), and as lymphoid-primed multipotent progenitors (LMPPs) differentiate into all lymphoid progenitors (ALPs). more...

(Submitter supplied) MicroRNAs (miRNAs) are a class of endogenous, non-coding RNAs that mediate post-transcriptional gene silencing by inhibiting mRNA translation and promoting mRNA decay. DICER1, an RNAse III endonuclease encoded by Dicer1, is required for processing short 21-22 nucleotide miRNAs from longer double-stranded RNA precursors. Here, we investigate the loss of Dicer1 in mouse postnatal male germ cells to determine how disruptions in the miRNA biogenesis pathway may contribute to infertility. more...

(Submitter supplied) To determine genes regulated independently of microRNAs in early haematopoietic progenitors (LSKs) we compared the expression profiles of Drosha or Dicer deficient LSKs and control. Those genes differentially expressed between Drosha or Dicer deficient LSKs are likely regulated indepedently of microRNAs as either Drosha or Dicer deletion will lead to a complete and equivalent loss of microRNAs.
