The small number of hematopoietic stem and progenitor cells in cord blood units limits their widespread use in human transplant protocols. We identified a family of chemically related small molecules that stimulates the expansion ex vivo of human cord blood cells capable of reconstituting human hematopoiesis for at least 6 months in immunocompromised mice. The potent activity of these newly identified compounds, UM171 being the prototype, is independent of suppression of the aryl hydrocarbon rec ...[more]

RNA-Seq analysis of primary AML specimens exposed to AhR modulating agents

Project description:The goal of the study was to identify genes that are directly or indirectly coregulated by the AhR pathway in primary human AML cells. Patient AML cells were treated for 16 hours with the two indirubin derivatives 6-bromoindirubin-3'oxime (BIO), 1-Methyl-6-bromoindirubin-3'oxime (MeBIO), the AHR-antagonist SR1 (StemReginin1), combinations of BIO+SR1 and MeBIO+SR1 or DMSO alone at indicated concentrations prior to RNA extraction for sequencing. RNA-Seq performed on 5 primary AML samples fresh (t0) and after exposure to AhR-agonists (2), -antagonist (1), and DMSO Contributor: Leucegene Project, IRIC

Integrated analysis of MLL-AF9 AML patients and model leukemias highlights RET and other novel therapeutic targets [RNA-Seq_normal]

Project description:Next generation DNA sequencing of acute myeloid leukemia (AML) patient samples has revealed novel recurrent mutations while at the same time highlighting the genetic heterogeneity of the disease. These observations suggest that an extraordinarily large number of combinations of mutations can contribute to leukemogenesis. In order to address the question of the contribution of patient genetic background to AML we have developed a model system to generate multiple human leukemias in a single donorâs genetic background. Stepwise RNA-seq data from this model shows that in the context of AML driven by the MLL-AF9 (MA9) oncogene, the genetic background of the donor does not have a detectable effect. Comparison of these model leukemias from multiple single donors to AML patient samples containing MA9 translocations revealed conserved gene expression patterns not previously highlighted in this genetic sub-type. We further demonstrate that the expression of one of these genes, RET, is essential both in vivo and in vitro growth of MA9 AMLs . Transcriptome of normal cells (CD34+) from different donors

Effect of LMP7 and MECL1-immunoproteasome subunits deficiency on the transcriptome of mouse bone marrow-derived dendritic cells

Project description:As regulators of protein degradation, proteasomes regulate practically all cellular functions. It is therefore logical to assume that replacement of the constitutive proteasome (CP) by its IFN- inducible homolog immunoproteasome (IP) could have far reaching effects on cell function. Accordingly, recent studies have revealed important roles for IPs in immune cells beyond MHC I-peptide processing. Moreover, the expression of IPs in non-immune cells from non-inflamed tissues suggests that the involvement of IPs is not limited to the immune system. We demonstrate here that IP-deficiency affects the transcription of 8104 genes in maturing dendritic cells (DCs). This occurs mainly through non-redundant regulation of key immune-related transcription factors by CPs and IPs. Additionally, IP-deficiency decreases DC's efficiency to activate CD8+ T cells in vivo. Our study reveals that the broad cellular roles of IPs could rely on transcription regulation and, more importantly, illustrates how IP-deficiency could generate MHC I-peptide processing-independent phenotypes. Examination of the transcriptome of WT and immunoproteasome-deficient cells at 4 different time points of dendritic cell maturation, in 4 experimental replicates (total of 32 samples).

Differential features of Aire-induced and Aire-independent promiscuous gene expression in thymic epithelial cells

Project description:Promiscuous gene expression (pGE) of numerous self-antigens in thymic epithelial cells (TEC) enables the elimination of self-reactive T cells. The autoimmune regulator (Aire) is the only known molecular determinant driving pGE in the thymus but the existence of Aire-independent mechanisms has been inferred. Here, we analyzed the poly(A)+ transcriptome of TEC populations by RNA-sequencing (RNA-seq) in order to reveal differential features of Aire-induced vs. –independent pGE. We report an unanticipated effect of Aire deletion on the proliferation and differentiation of cortical TEC. Moreover, the RNA-seq data reveal the breath of Aire-induced and –independent pGE in medullary TEC (mTEC) subsets and the extent of thymic peripheral tissue representation. The results suggest that Aire-induced promiscuously expressed transcripts affect several functions with far reaching biological consequences in mTEC. High-throughput characterization of TEC transcriptomes will enable progress in understanding TEC biology and the establishment of self-tolerance. The mRNA profiles of cTEC, mTEClo and mTEChi from 6-8 week-old wild type (WT) and Aire-/- (KO) mice were generated by RNA-sequencing using Illumina HiSeq2000.
