(Submitter supplied) Bmi1 is a protein member of PRC1 and plays a major role in the maintenance of gene repression. We are studying the role of Bmi1 in the context of hematopoietic stem cell aging. We used microarray to study the gene expression profile of LSK cells in relation to the knocking-out of Bmi1 in vivo

(Submitter supplied) Bmi1 is a component of polycomb repressive complex 1 and its role in the inheritance of the stemness of adult somatic stem cells has been well characterized. Bmi1 maintains the self-renewal capacity of adult stem cells, at least partially, by repressing the Ink4a/Arf locus that encodes a cyclin-dependent kinase inhibitor, p16Ink4a, and a tumor suppressor, p19Arf 14. Deletion of both Ink4a and Arf in Bmi1-deficient mice substantially restored the defective self-renewal capacity of HSCs and neural stem cells.

(Submitter supplied) Bone marrow mesenchymal stromal cells (MSCs) that express high levels of stem cell factor (SCF) and CXC chemokine ligand 12 (CXCL12) are one crucial component of the hematopoietic stem cell (HSC) niche. While the secreted factors produced by MSCs to support HSCs have been well described, little is known regarding the transcriptional regulators controlling the cell fate of MSCs and thus indirectly maintaining HSCs. more...

(Submitter supplied) Bmi1 is a component of the Polycomb-repressive complexes (PRC) and essential for maintaining the pool of adult stem cells. PRC are key regulators for embryonic development by modifying chromatin architecture and maintaining gene repression. To assess the role of Bmi1 in pluripotent stem cells and upon exit from pluripotency during differentiation, we studied forced Bmi1 expression in mouse embryonic stem cells (ESC). more...

Analysis of Bmi1 transduced CCE embryonic stem cells (ESC) and CCE ESC differentiated by embryoid body assay. Bmi1 is essential for maintaining the pool of adult stem cells. Results provide insight into role of Bmi1 in ESC-derived hematopoietic cell transition from pluripotency to differentiation.

(Submitter supplied) Regulation of lineage potential and transcriptional priming by Ikaros. New insight is provided into a bivalent regulation of lineage priming in the HSC and its lympho-myeloid restricted progeny the LMPP by the lymphoid lineage-determining factor Ikaros Whereas Ikaros is responsible for the activation of a cascade of lymphoid expression programs and for the establishment of lymphoid potential from the HSC to the LMPP it is also responsible for the repression of stem cell and erythroid genetic programs that are incompatible with further lineage restrictions emanating from the LMPP Keywords: Ikaros null versus wt

(Submitter supplied) In order to identify the key genes for self-renwal abiity of innate immune B-1a cells, we have gene expression analysis using Aglinant Whole Mouse gGenome Oligo Microarrays performed by Miltenyi Biottec. We isolated peritoneal B-1a cells from wild type mice and Bmi1 kockout (KO) mice that lost self-renewal ability of B-1a cells, and submitted purified RNA from each samples to Miltenyi.

(Submitter supplied) Stem cell differentiation and lineage specification depend on coordinated programs of gene expression, but our knowledge of the chromatin modifying factors regulating these events remains incomplete. Ubiquitination of histone H2A (H2A-K119u) is a common chromatin modification associated with gene silencing, and controlled by the ubiquitin-ligase polycomb repressor complex 1 (PRC1) and H2A-deubiquitinating enzymes (H2A-DUBs). more...

(Submitter supplied) Polycomb group (PcG) proteins control organism development by regulating the expression of developmental genes. Transcriptional regulation by PcG proteins is achieved at least partly through the PRC2-mediated methylation on lysine 27 of histone H3 (H3K27) and PRC1-mediated ubiquitylation on lysine 119 of histone H2A (uH2A). As an integral component of PRC1, Bmi1 has been demonstrated to be critical for H2A ubiquitylation. more...

(Submitter supplied) Conditional deletion of Geminin from the entire hematopoietic compartment using Vav1:iCre mice led to defective hematopoiesis/dyserythropoiesis in E15.5 mouse embryos. The present data set includes data from lineage-negative cells isolated from homogenized livers that were dissected from E15.5.dpc embryos. The two conditions compared were wild-type versus Geminin-KO Lin- cells. The cells were collected from littermates.

(Submitter supplied) We have previously shown that conditional overexpression of Bmi1 in NSC increases their proliferation both in the developing neocortexand in the postnatal brain (Yadirgi et al. 2011). However, during embryonic development, increased and ectopic proliferation induced by overexpression of Bmi1 in progenitors committed toward a neuronal lineage triggered apoptosis, leading eventually to a reduced overall brain size (Yadirgi et al. more...
