Description
Epigenetic regulation of key transcriptional programs is a critical mechanism that controls hematopoietic development and thus aberrant expression patterns or mutations in epigenetic regulators occur frequently in hematologic malignancies. We demonstrate that the Polycomb protein L3MBTL1, which is monoallelically deleted in 20q- myeloid malignancies, represses the ability of stem cells to drive hematopoietic-specific transcriptional programs by regulating the expression of SMAD5 and impairing its recruitment to target regulatory regions. Indeed, knock-down of L3MBTL1 promotes the development of hematopoiesis and impairs neural cell fate in human pluripotent stem cells. We also found a role for L3MBTL1 in regulating SMAD5 target gene expression in mature hematopoietic cell populations, thereby affecting erythroid differentiation. Taken together, we have identified epigenetic priming of hematopoietic-specific transcriptional networks, which may assist in the development of therapeutic approaches for patients with anemia.

Description
Transcriptional profiling of Murine BaF3 cells infected with MPLW515L grown under either normal conditions (Naive) or in 0.8 uM INCB18424 for 4-6 weeks (Persistent). Naive and Persistent cells were then treated with either DMSO (Control) or 0.8 uM INCB18424 for 4 hours. Goal was to determine transcriptional changes conditioned upon sensitivity/resistance of BaF3 MPLW515L mutants to JAK1/2 specific inhibitor.

Description
Hox genes are critical developmental transcription factor. We found that in mice with disrupted expression of Hoxa6, Hoxb6 and Hoxc6 there is significantly disrupted endocrine pancreas development. We used microarray analysis to probe for possible molecular mechanisms involed in Hox6 signaling in pancreas development.

Description
Macrophages were infected with low (PR8) and high pathogenic influenza viruses (FPV and H5N1). To our surprise a genome-wide comparative systems biology approach revealed that in contrast PR8 infections with HPAIV H5N1 and FPV result in a reduced immune response of human macrophages contradicting a primary role of this cell type for the cytokine storm.

Description
Loss-of-function studies are fundamental for dissecting gene function. Yet, methods to rapidly and effectively perturb genes in mammalian cells are scarce. We present a novel system, deliverable with only two lentiviral vectors, which enables simultaneous control over two different proteins in the same cell. By harnessing the plant auxin and jasmonate hormone-induced degradation pathways, combined with RNA interference, this system allows constitutive depletion of two endogenous proteins and their replacement with two exogenous proteins whose degradation is rapidly and reversibly induced by external ligands, representing a dual analog molecular tuner. Focusing on NANOG, CHK1 and NOTCH1 in embryonic stem cells and p53 in cancer cells we have validated the efficiency, rapidity, reversibility, titratability and multiplicity of the engineered tuners, and demonstrated their potential to facilitate previously-unfeasible experimental approaches and to generate novel biological insights. Overall design: For mRNA-Seq preparation, coronatine/DMSO treated cells were collected.

Description
Dendritic cells (DCs) in lymphoid tissue comprise conventional DCs (cDCs) and plasmacytoid DCs (pDCs) that develop from common DC progenitors (CDPs). CDPs are Flt3+c-kitintM-CSFR+ and reside in bone marrow. Here we describe a two-step culture system that recapitulates DC development from c-kithiFlt3-/lo multipotent progenitors (MPPs) into CDPs and further into cDC and pDC subsets. MPPs and CDPs are amplified in vitro with Flt3 ligand, stem cell factor, hyper-IL-6 and insulin- like growth factor-1. The four-factor cocktail readily induces self-renewal of MPPs and their progression into CDPs and has no self-renewal activity on CDPs. The amplified CDPs respond to all known DC poietins and generate all lymphoid tissue DCs in vivo and in vitro. Additionally, in vitro CDPs recapitulate the cell surface marker and gene expression profile of in vivo CDPs and possess a DC-primed transcription profile. Transforming growth factor-1 (TGF-1) impacts on CDPs and directs their differentiation towards cDCs. Genome-wide gene expression profiling of TGF-1-induced genes identified transcription factors, such as interferon regulatory factor-4 (IRF-4) and RelB, that are implicated as instructive factors for cDC subset specification. TGF-1 also induced the transcription factor inhibitor of differentiation/DNA binding 2 (Id2) that suppresses pDC development. Thus, TGF-1 directs CDP differentiation into cDC by inducing both cDC instructive factors and pDC inhibitory factors.

Description
In order to investigate genes regulated by Wnt/Beta-catenin-signaling in immortalized mouse adrenocortical cells, we treated a pair of ATCL7 cell cultures, one with BIO, a small molecule mimicking Wnt/Beta-catenin-signaling, the other with a control treatment. We repeated this 3 additional times resulting in 4 pairs of samples. The Wnt/beta-catenin pathway is not basally active in ATCL7 cells, nor do these cells appear to contain any mutations in the Wnt/Beta-catenin pathway. ATCL7 cells were grown under standard conditions at 37C in a humidified incubator containing 5% CO2. 250,000 ATCL7 cells per sample were treated with 0.5uM BIO (6-Bromoindirubin-3'-oxime) or 0.01% DMSO (v/v) for 24 hours, in DMEM:F12 growth media containing 100U/mL pencillin/streptomycin, 1X insulin-transferrin-selenium-X, 0.025% fetal bovine serum and 0.025% horse serum. Cells were harvested and RNA was extracted using an RNeasy Plus Mini Kit (Qiagen). Biotinylated cDNA were prepared according to the Ambion WT kit protocol from 250 ng total RNA (GeneAtlas WT Expression Kit User Manual P/N 702935 Rev. 3). We assayed the targets with Affymetrix Mouse Gene ST 1.1 strip arrays. We modeled the data using paired T-tests for each probe-set. We also supply a supplementary file holding the data and some statistical analysis, as well as probe-set annotation that we used at that time (users may wish to obtain new annotation though). We analyzed only 28944 probe-sets with category "main", "---", and "flmrna->unmapped" according to Affymetrix annotation.
