(Submitter supplied) We report that IKZF2 is required for maintaining chromatin accessibility in leukemic stem cells in myeloid leukemia. RNA seq and ATAC-seq were performed to investigate the changes in chromatin accessibility of differentially expressed genes in leukemic stem cells when IKZF2 was absent. We found that IKZF2 maintains open accessibility in self-renewal transcription factor motifs such as HOXA9 sites whereas motifs of differentiation transcription factors including C/EBPs are kept closed.

(Submitter supplied) Standard chemotherapy for acute myeloid leukemia (AML) targets proliferative cells and efficiently induces complete remission; however, many patients relapse and die of their disease. Relapse is caused by leukemia stem cells (LSCs), the cells with self-renewal capacity. Self-renewal and proliferation are mutually exclusive in normal hematopoietic stem cells (HSCs) in steady state conditions. If these functions are also mutually exclusive in LSCs, then antiproliferative therapies may fail to target self-renewal, allowing for relapse. more...

(Submitter supplied) Leukemia stem cells (LSCs) are found in most aggressive myeloid diseases and contribute to therapeutic resistance. Genetic and epigenetic alterations cause a dysregulated developmental program in leukemia. The MSI2 RNA binding protein has been previously shown to predict poor survival in leukemia. We demonstrate that the conditional deletion of Msi2 results in delayed leukemogenesis, reduced disease burden and a loss of LSC function. more...

(Submitter supplied) Zeb1, a zinc finger E-box binding homeobox epithelial-mesenchymal (EMT) transcription factor, confers properties of ‘stemness’, such as self-renewal, in cancer. Yet little is known about the function of Zeb1 in adult stem cells. Here, we used the hematopoietic system, as a well-established paradigm of stem cell biology, to evaluate Zeb1 mediated regulation of adult stem cells. We employed a conditional genetic approach using the Mx1-Cre system to specifically knockout (KO) Zeb1 in adult hematopoietic stem cells (HSCs) and their downstream progeny. more...

(Submitter supplied) Acute myeloid leukemia (AML) with chromosomal rearrangements involving the H3K4 methyltransferase mixed-lineage leukemia (MLL) is an aggressive subtype with low overall survival. MLL rearrangements rapidly transform hematological stem and progenitor cell (HSPC) to leukemia stem cell (LSC). Bortezomib (Velcade) is used widely in hematological malignancies. However, it is still unknown whether bortezomib possesses anti-self-renewal and anti-leukemogenesis of LSC in AML with MLL rearrangements. 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...

The leukemia stem cell fraction in these two type of leukemias shared a common self-renewal pathway with normal hematopoietic stem cells. more...

(Submitter supplied) The polycomb group (PcG) proteins function in gene silencing through histone modifications. They form chromatin-associated multiprotein complexes, termed polycomb repressive complex (PRC) 1 and PRC2. These two complexes work in a coordinated manner in the maintenance of cellular memories through transcriptional repression of target genes. EZH2 is a catalytic component of PRC2 and trimethylates histone H3 at lysine 27 to transcriptionally repress the target genes. more...

(Submitter supplied) Acute myeloid leukemia (AML) with rearrangement of the mixed-lineage leukemia (MLL) gene are the most aggressive hematopoietic malignancies. Previous studies demonstrated the distribution of several epigenetic modifications including H3K9me3, H3K79me2, H3K36me3, H3K4me3 and H3K27me3, in MLL-AF9 transformed murine cells. Here, we examined the H3K9me3 distribution in c-Kit+ cells (enriched with stem/progenitor cells) from both MLL-AF9 transformed murine cells in parallel with control wild-type cells, and found an overall lower distribution of H3K9me3 in leukemia stem cells than normal hematopoietic stem/progenitor cells.

(Submitter supplied) Acute myeloid leukemias (AMLs) with rearrangement of the mixed-lineage leukemia (MLL) gene are the most aggressive hematopoietic malignancies. By analyzing the clinical data, we found the expression of SUV39H1 was significantly decreased in AML patients and MLL-AF9 (MA9) induced AML mice, in comparison with controls. Remarkably, when overexpress Suv39h1 in MA9 AML mice, the survival of AML mice was significantly prolonged.To examined the mechanism mediated by Suv39h1 overexpression (SUV-OE), we performed the RNAseq profiling of SUV-OE MA9 AML cells and control cells.
