Analysis of mononuclear cells from acute myeloid leukemia patients (AML 1-4) cultured in the presence of interleukin-3 (IL-3) for up to 16hrs. The overexpression of IL-3Rα in AML has been associated with reduced overall survival. Results provide insight into the role of IL-3 signaling in AML.

(Submitter supplied) Aberrant activation of β-catenin is a common event in Acute Myeloid Leukemia (AML), and is recognized as an independent predictor of poor prognosis. Although increased β-catenin signaling in AML has been associated with AML1-ETO and PML-RARα translocation products, and activating mutations in the FLT3 receptor, it remains unclear which mechanisms activate β-catenin in AML more broadly. Here, we describe a novel link between interleukin-3 (IL-3) signaling and the regulation of β-catenin in myeloid transformation and AML. more...

(Submitter supplied) Activation or maintenance of a leukemia stem cell self-renewal pathway in downstream myeloid cells is an important component of AML development We generated either MLL-AF9 mediated murine leukemias that originate from committed progenitor (GMP) cells or Hoxa9/Meis1a mediated murine leukemias that originate from hematopoietic stem cells (HSC). The leukemia stem cell fraction in these two type of leukemias shared a common self-renewal pathway with normal hematopoietic stem cells. more...

Analysis of acute myelogenous leukemia (AML) leukemia stem cells (LSC) induced either by Hoxa9/Meis1a oncogenes or MLL-AF9 oncoprotein. LSC self-renewal pathway in myeloid cells is central to AML development. Results provide insight into the molecular mechanisms underlying development of LSC in AML.

(Submitter supplied) OBJECTIVE: MEIS1, a HOX cofactor, collaborates with multiple HOX and NUP98-HOX fusion proteins to accelerate the onset of acute myeloid leukemia (AML) through largely unknown molecular mechanisms. MATERIALS AND METHODS: To further resolve these mechanisms, we conducted a structure-function analysis of MEIS1 and gene-expression profiling, in the context of NUP98-HOXD13 (ND13) leukemogenesis. RESULTS: We show, in a murine bone marrow transplantation model, that the PBX-interaction domain, the homeodomain, and the C-terminal domain of MEIS1, are all required for leukemogenic collaboration with ND13. more...

(Submitter supplied) To understand better the mechanisms controlling the balance between proliferation and and differentiation during myelopoiesis we have utilized teh bi-potent FDB1 myeloid cell line which differentiates to granulocytes and macrophages in response to GM-CSF and thus provides a dissectable model to analyse the switch between growth and differentiation. This was further studied using this cell line in which a second site mutation Y577F had been generated. more...

(Submitter supplied) Canonical Wnt signaling output is mediated by β-catenin, which interacts with LEF/TCF transcription factors and recruits a general transcriptional activation complex to its C-terminus. Its N-terminus binds BCL9/9L proteins, which bind co-activators that in mammals contribute to fine-tuning the transcriptional output. We found that a BCL9/9L-dependent gene expression signature was strongly associated with patient outcome in colorectal cancer and that stem cell and mesenchymal genes determine its prognostic value. more...

(Submitter supplied) We analyzed RNA-seq, ATAC-seq, ChIP-seq and 4C-seq data to find that CTCF binding site located between HOXA7 and HOXA9 genes (CBS7/9) is critical for establishing and maintaining aberrant HOXA9-HOXA13 gene expression in AML. Disruption of the CBS7/9 boundary resulted in spreading of repressive H3K27me3 into the posterior active HOXA chromatin domain that subsequently impaired enhancer/promoter chromatin accessibility and disrupted ectopic long-range interactions among the posterior HOXA genes. more...

(Submitter supplied) Acute myeloid leukemia (AML) is a heterogeneous neoplastic disorder, in which only a subset of cells have function as leukemia-initiating cells (LICs). In this study, we prospectively evaluated leukemia-initiating capacity of fractionated subpopulations of AML cells depending on expression of a nucleolar GTP binding protein, Nucleostemin (NS). To monitor NS expression in living AML cells, we generated a mouse AML model using a transgenic mouse, in which green florescence protein (GFP) is expressed under the control of particular region of NS promoter (NS-GFP). more...

More recently osteoblasts were implicated in pre-leukemic conditions in mice. Yet, it has not been shown that a single genetic event taking place in osteoblastscan induce leukemogenesis. We show here that in mice, an activating mutation of β-catenin leading to development of acute myeloid leukemia (AML) with common chromosomal aberrationsand cell autonomous progression. more...

(Submitter supplied) The molecular mechanism defining susceptibility of normal cells to oncogenic transformation may be a valuable therapeutic target. We characterized the cell of origin and its critical pathways in MN1 leukemias. Common myeloid (CMP), but not granulocyte-macrophage progenitors (CMP) could be transformed by constitutively overexpressed MN1. Complementation studies of CMP-signature genes in GMPs demonstrated that leukemogenicity of MN1 required the MEIS1/abdB-like HOX protein complex. more...

(Submitter supplied) The translocation t(7;12)(q36;p13) occurs in infants and very young children with AML and usually has a fatal prognosis. Whereas the transcription factor ETV6, located at chromosome 12p13, has largely been studied in different leukemia types, the influence of the translocation partner HB9 (chr. 7q36), is still unknown. This is particularly surprising as ectopic expression of HB9 is the only recurrent molecular hallmark of translocation t(7;12) AML. more...
