(Submitter supplied) Erg is an ETS family transcription factor frequently overexpressed in human leukemias and has been implicated as a key regulator of hematopoietic stem cells (HSCs). However how Erg controls normal hematopoiesis, particularly at the stem cell level, remains poorly understood. Using homologous recombination, we generated an Erg knockdown allele (Ergkd) in which Erg expression can be restored upon Cre-mediated excision of a Stopper cassette. more...

(Submitter supplied) Hematopoietic stem cells are both necessary and sufficient to sustain the complete blood system of vertebrates. Here we show that Nfix, a member of the nuclear factor I (Nfi) family of transcription factors, is highly expressed by hematopoietic stem and progenitor cells (HSPC) of murine adult bone marrow. Although shRNA mediated knockdown of Nfix expression in Lineage-Sca-1+c-Kit+ HSPC had no effect on in vitro cell growth or viability, Nfix-depleted HSPC displayed a significant loss of colony forming potential, as well as short- and long-term in vivo hematopoietic repopulating activity. more...

(Submitter supplied) Estrogens are potential regulators of the hematopoietic stem cell (HSC) niche and have effects on mature hematopoietic cells; however, whether estrogen signaling directly regulates normal and malignant HSC remains unclear. We demonstrate differential expression and specific roles of estrogen receptors (ER) in hematopoietic progenitors. ERa activation in short-term HSC and multipotent progenitors induced apoptosis. more...

(Submitter supplied) Hi-C was used to examine long range chromatin interactions in B cell progenitors in the presence and absence of the Erg transcription factor. Specifically, OP9 cultured B220+ B-cell progenitors derived from the bone marrow of Rag1CreT/+;ErgΔ/Δ mice and from Rag1CreT/+ and Rag1Cre+/+;Erg fl/fl control mice were isolated and DNA interactions were profiled by in situ Hi-C.

(Submitter supplied) MYSM1 is a transcriptional regulator essential for HSC function and hematopoiesis. We established that p53 activation is a common mechanism mediating HSC dysfunction, MPP depletion, and lymphopenia in Mysm1-deficiency, however, the specific p53-induced effectors that trigger dysfunction in Mysm1-deficient HSPCs remain unknown. Here, we performed RNA-Seq of Lin-cKit+Sca1+CD150+ and CD150- HSPCs from Mysm1-/-Puma-/-, Mysm1-/-Puma+/-, Puma-/-, and wild-type mice; (Mysm1-/-Puma+/- phenocopies Mysm1-/-). more...

(Submitter supplied) To better understand the differentiation and survival defect of Nrf2-/- HSPC, we performed gene expression studies on KSL cells isolated by FACS from Nrf2+/+ and Nrf2-/- mice. Gene expression data suggests that loss of Nrf2 leads to global defects in cytokine signaling, and the administration of the exogenous granulocyte colony-stimulating factor (G-CSF) improved HSPC survival despite increasing intracellular ROS.

(Submitter supplied) Although hematopoietic stem and progenitor cells (HSPCs) become activated in the cell-cycle status after chemotherapy to supply hematopoietic loss, the detailed mechanisms of activation remain unknown. Here we show that Sca1+ macrophages play a key role for bone marrow (BM) recovery through granulocyte-macrophage colony-stimulating factor (GM-CSF) secretion. By analyzing gene expression profiles of HSPCs lodged in 5-fluolouracil (5-FU)-treated mice, we found GM-CSF as a key proliferative signal. more...

(Submitter supplied) The Hematopoietically-expressed homeobox transcription factor (Hhex) is important for the maturation of definitive hematopoietic progenitors and B-cells during development. We have recently shown that in adult hematopoiesis, Hhex is dispensable for maintenance of hematopoietic stem cells (HSCs) and myeloid lineages but essential for the commitment of Common Lymphoid Progenitors (CLPs) to lymphoid lineages. more...

(Submitter supplied) Gata2, a zinc finger TF, is essential for the generation and survival of HSCs in the embryo and has been implicated in the pathogenesis of AML, yet the requirement for Gata2 in adult HSCs and LSCs remains unclear. Using a conditional mouse model where Gata2 was deleted specifically in hematopoietic cells, we show that knockout of Gata2 leads to a rapid and complete cell-autonomous loss of adult HSCs. more...

(Submitter supplied) Loss of Setd1b in adult mice using both ubiquitous and hematopoietic-specific deletion strategies caused lethality arising from severe hematopoietic defects. To identify genes regulated by Setd1b in HSPCs we performed RNA-seq analysis of the LSK (Lin-, Sca+, Kit+) compartment in the bone marrow. Mice carrying heterozygous and homozygous conditional Setd1b alleles and Rosa26-Cre-ERT2 were treated with Tamoxifen for 6 days (4 days gavage - 3 days pause - 2 days gavage). more...
