Project description:microRNA miR-144/451 is highly expressed during erythropoiesis. We deleted the miR-144/451 gene locus in mice and compared the transcriptomes of miR-144/451-null bone marrow erythroid precursors to stage-matched wild-type control cells.

Project description:Bcl11a is a transcription factor known to regulate lymphoid and erythroid development. Recent bioinformatic analysis of global gene expression patterns has suggested a role for Bcl11a in the development of dendritic cell (DC) lineages. We tested this hypothesis by analyzing the development of DC and other lineages in Bcl11a(-/-) mice. We show that Bcl11a is required for expression of IL-7 receptor (IL-7R) and Flt3 in early hematopoietic progenitor cells. The loss of IL-7R(+) common lymphoid progenitors accounts for previously described lymphoid defects in Bcl11a(-/-) mice. In addition, we found severely decreased numbers of plasmacytoid dendritic cells (pDCs) in Bcl11a(-/-) fetal livers and in the bone marrow of Bcl11a(-/-) fetal liver chimeras. Moreover, Bcl11a(-/-) cells show severely impaired in vitro development of Flt3L-derived pDCs and classical DCs (cDCs). In contrast, we found normal in vitro development of DCs from Bcl11a(-/-) fetal liver cells treated with GM-CSF. These results suggest that the persistent cDC development observed in Bcl11a(-/-) fetal liver chimeras reflects derivation from a Bcl11a- and Flt3-independent pathway in vivo. We compared global gene expression by microarray for donor-derived wild-type and Bcl11a(-/-) populations isolated from chimeric bone marrow to identify Bcl11a target genes that explain its role in hematopoietic progenitors.

GMP and MPP populations were sorted from fetal liver chimeras and pooled by donor genotype. RNA was isolated using an RNAqueous-Micro Kit (Ambion) and submitted for amplification, labeling and hybridization. Expression values were analyzed after RMA quantile normalization using ArrayStar software (DNASTAR).

Project description:microRNA miR-144/451 is highly expressed during erythropoiesis. We deleted the miR-144/451 gene locus in mice and compared the transcriptomes of miR-144/451-null bone marrow erythroid precursors to stage-matched wild-type control cells. Ter119+/CD71+/FSC-high bone marrow erythroblasts were sorted directly into Trizol LS reagent. Total RNAs extracted from three miR-144/451 knock-out and three wide type mice were analyzed using Affymetrix Mouse Genome 430 2.0 Arrays.

Project description:BCL11A is a critical mediator of hemoglobin switching and gamma-globin silencing. In this study, we showed the BCL11A is required in vivo for developmental silencing of gamma-globin genes in adult animals. We used microarray to determine the changes in gene expression profile after loss of BCL11A in adult erythroid cells CD71+Ter119+ erythroid progenitor cells were FACS-sorted from bone marrows of 6-week old control (Bcl11a +/+) and BCL11A knockout (Bcl11a fl/fl EpoR-Cre+) mice.

Project description:To get insight into lineage-specific TRIM33 functions, TRIM33 ChIP-seq was carried out in non-differentiated erythroid (MEL NI), differentiated erythroid (MEL I), immature myeloid (32D). In addition, we compared the genome-wide profiles of RNA PolII occupancy between wild-type bone marrow-derived macrophages (BMDM) and Trim33-/- BMDM activated with LPS.
