Analysis of c-Kit+Sca-1+Lin- hematopoietic stem cells (HSCs) lacking Runx1 or expressing the runt homology domain, RUNX1 (41-214). RUNX1(41-214) expression induces myelodysplastic syndrome (MDS) in mice. Results provide insight into molecular basis of MDS progression induced by RUNX1 (41-214).

(Submitter supplied) Mutations of RUNX1 are detected in patients with myelodysplastic syndrome (MDS). In particular, C-terminal truncation mutations lack a transcription regulatory domain and have increased DNA binding through the runt homology domain (RHD). The expression of the RHD, RUNX1(41-214), in mouse hematopoietic cells induced progression to MDS and acute myeloid leukemia (AML). Analysis of pre-myelodysplastic animals revealed expansion of c-Kit+Sca-1+Lin- (KSL) cells and skewed differentiation to myeloid at the expense of the lymphoid lineage. more...

(Submitter supplied) We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mammalian cells. By obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of mouse embryonic stem cells, neural progenitor cells and embryonic fibroblasts. We find that lysine 4 and lysine 27 trimethylation effectively discriminates genes that are expressed, poised for expression, or stably repressed, and therefore reflect cell state and lineage potential. more...

(Submitter supplied) Disrupting mutations of the RUNX1 gene are found in 10% of patients with myelodysplasia (MDS) and 30% of patients with acute myeloid leukemia (AML). Previous studies have revealed an increase in hematopoietic stem cells (HSCs) and multipotent progenitor (MPP) cells in conditional Runx1-knockout (KO) mice, but the molecular mechanism is unresolved. We investigated the myeloid progenitor (MP) compartment in KO mice, arguing that disruptions at the HSC/MPP level may be amplified in downstream cells. more...

(Submitter supplied) RUNX1 is among the most frequently mutated genes in human leukemia, and the loss or dominant-negative suppression of RUNX1 function is found in myelodysplastic syndrome and acute myeloid leukemia (AML). However, how post-translational modifications (PTMs) of RUNX1 affect its in vivo function and whether PTM dysregulation of RUNX1 can cause leukemia are largely unknown. We performed targeted deep sequencing on a family with 3 occurrences of AML and identified a novel RUNX1 mutation R237K. more...

(Submitter supplied) In order to identify genes that are activated in differentiating WT ESCs, but are missing in Tal-1-/- and Runx1-/- ESCs, and which might be involved in the generation of definitive hematopoietic progenitors and their specification thereafter, we performed microarray analyses on purified Flk-1+ cells, differentiated from these ESCs for 4, 5, and 6 days “in vitro”.

(Submitter supplied) Early hematopoiesis is a continuous process in which hematopoietic stem and progenitor cells (HSPCs) gradually differentiate and are primed toward specific lineages. Aging and myeloid malignant transformation are characterized by changes in the composition and regulation of HSPCs. In this study, we evaluated HSPCs obtained from young and elderly healthy donors using single-cell RNA sequencing to identify the transcriptional and regulatory perturbations associated with healthy aging at single cell resolution. more...

(Submitter supplied) The transcription factor Runx1 is essential for the establishment of definitive hematopoiesis during embryonic development. In adult blood homeostasis, Runx1 plays a pivotal role in the maturation of lymphocytes and megakaryocytes. Furthermore, Runx1 is required for the regulation of hematopoietic stem and progenitor cell (HSPC) pools. However, how Runx1 orchestrates self-renewal and lineage choices in combination with other factors is not well understood. more...

(Submitter supplied) Mesenchymal stromal cells (MSC) are involved in the pathogenesis of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), but how they contribute to the expansion of malignant cells and hematopoietic failure is poorly understood. To further characterize the pathological phenotype we performed RNA sequencing of MSC from patients with MDS and AML. Data analysis revealed a specific molecular signature with a significant overlap of genes commonly deregulated in all MDS subtypes and in AML. more...

(Submitter supplied) Hematological malignancies are characterised by a block in differentiation, which is in many cases caused by recurrent mutations affecting the activity of hematopoietic transcription factors. RUNX1-EVI1 is a fusion protein formed by the t(3;21) translocation linking two transcription factors required for normal hematopoiesis. RUNX1-EVI1 is found in myelodysplastic syndrome, secondary acute myeloid leukemia, and blast crisis of chronic myeloid leukemia; with clinical outcomes being worse than in patients with RUNX1-ETO, RUNX1 or EVI1 mutations alone. more...

(Submitter supplied) Recent studies have showed that loss-of-function mutations of EZH2, a catalytic component of polycomb repressive complex 2, are often associated with RUNX1 mutations in myelodysplastic syndrome (MDS) patients. We established a novel MDS model mouse by transducing a RUNX1S291fs mutant in hematopoietic stem cells followed by deletion of Ezh2 and found that Ezh2 loss significantly promoted RUNX1S291fs-induced MDS.

(Submitter supplied) RUNX1 is crucial for multiple stages of hematopoiesis and its mutation can cause familial platelet disorder with predisposition to acute myeloid leukemia (FPD/AML). We aim to study the role of RUNX1 in megakaryocyte-biased HSCs differentiation to megakaryocytes. Here, by using Runx1F/FMx1-Cre mouse model ,we sorted CD41pos HSCs and CD41neg HSCs in both RUNX1 WT and KO, and tested the RUNX1 direct binding targets in these cells genome.
