(Submitter supplied) Acute myeloid leukemia (AML) is characterized by accumulation of myeloid blast cells in the bone marrow. Despite all efforts, prognosis of AML patients remains poor, warranting new therapeutic approaches. A single nucleotide polymorphism of growth factor independence 1 (GFI1), a hematopoietic transcription factor, generates a protein with an asparagine (GFI136N) instead of a serine at position 36 (GFI136S), which we have previously reported to be associated with de novo AML in humans. more...

(Submitter supplied) GFI1 is a transcription factor and was implicated in the development of MDS. Reduced expression of GFI1 or presence of the GFI1-36N variant leads to epigenetic changes. Using GFI1-36S, -36N -KD, NUP98-HOXD13-tg mice and curcumin (a natural histone acetyltransferase inhibitor (HATi)), we now demonstrate that expansion of GFI1-36N or –KD, NUP98-HODXD13 leukemic cells can be delayed. Curcumin treatment significantly reduced AML progression in GFI1-36N or -KD mice and prolonged AML-free survival. more...

(Submitter supplied) GFI1 is a transcriptional repressor protein that plays an essential role in HSCs development, lymphoid and myeloid differentiation and Acute Myeloid Leukaemic (AML) pathogenesis. Low expression levels of GFI1 is associated with a poor prognosis in AML development. In addition, a single nucleotide polymorphism (SNP) variant of GFI1 results in the generation of GFI1 protein with asparagine (N) instead of serine (S) at the 36th amino acid position, known as GFI136N. more...

(Submitter supplied) MDS is characterized by a disturbed function of the myeloid lineage of the hematopoietic system that may transform to AML, a malignant disease of the myeloid compartment. Epigenetic and genetic aberrations contribute to the initiation and progression of MDS/AML. GFI1 is a transcriptional repressor, which regulates expression of its target genes by, among other approaches, recruiting HDACs to its target genes to remove histone 3 lysine 9 (H3K9) acetylation, a marker for active gene expression. more...

(Submitter supplied) GFI136N is a coding Single Nucleotide Polymorphism (SNP) in the gene GFI1 that increases the risk for Acute myeloid leukemia (AML) by 60%. It is present in 3-5% of Caucasians and has a prevalence of 12% among AML patients. We generated knockin mice expressing either the human GFI136N variant or the more common GFI136S form and observed that GFI136N, in contrast to GFI136S, lacked the ability to bind to the Gfi1 target gene and leukemia associated transcription factor Hoxa9 in myeloid precursors and failed to initiate the histone modifications that regulate HoxA9 expression. more...

(Submitter supplied) Determine the differences in gene expression profiles of MV-4-11 AML cells treated with HDAC1/2-selective inhibition, azacitidine, or the combination of the two agents. Acute myeloid leukemia (AML) is a heterogeneous group of hematopoietic stem cell disorders characterized by defects in myeloid differentiation and increased proliferation of neoplastic hematopoietic precursor cells. Outcomes for patients with AML remain poor, highlighting the need for novel treatment options. more...

(Submitter supplied) GFI1 is a transcriptional repressor protein that represses the transcription by mediating chromatin modifications such as histone demethylation, methylation and deacetylation of target genes. The genes with significant open chromatin configuration in the promoter and enhancer regions of GFI1-KI and GFI1-KD mice are identified in this study. This aids in the identification of unique additional genes that might be GFI1 protein's potential targets. more...

(Submitter supplied) Lsd1KO and ATRA treatment in Hoxa9/Meis1- and MN1-transformed myeloid progenitor cells LSD1 has emerged as a promising epigenetic target in the treatment of acute myeloid leukemia (AML). Inhibition of LSD1 has been shown to induce differentiation and facilitate the responsiveness of AML cells to all-trans retinoic acid. We used two murine AML models based on retroviral overexpression of Hoxa9/Meis1 (H9M) or MN1 to study the effect of Lsd1 knockout in AML. more...

(Submitter supplied) AML1-ETO (Acute Myeloid Leukemia 1-Eight Twenty One) caused by the translocation t(8;21)(q22;q22) is a mutated transcription factor contributing to AML development. Although associated with a favorable prognosis, half of the patients fail to achieve long-term survival. We examined the role of the transcription factor Growth factor independence 1 (GFI1) in the initiation and progression of leukemia and exploited the use of a drug targeting GFI1 expression in the context of AML1-ETO associated AML. more...

(Submitter supplied) Activation of GFI1-super-enhancer (GFI1-SE) by a LSD1 inhibitor NCD38 was relevant to myeloid differentiation and antileukemia effect in human erythroleukemia cells (HEL cells). Thus, we investigated the role of GFI1-SE upon NCD38 treatment in HEL cells. We established three independent sublines with bi-allelic deletion of GFI1-SE (CCE2 #114, #141, and #216) using CRISPR-Cas9 genome editing system in HEL cells and a classical limiting dilution method. more...

(Submitter supplied) INCB059872 is a selective irreversible inhibitor of Lysine-Specific Demethylase 1 (LSD1) that is in phase 1 clinical trials in hematopoietic malignancies. We evaluated a pre-treatment bone marrow sample of a patient who showed a clinical response to INCB059872 + azacitidine treatment. Single-cell RNA-sequencing (scRNA-seq) showed that INCB059872 caused a shift in gene expression that was associated with GFI1/GFI1B regulation.

(Submitter supplied) INCB059872 is a selective irreversible inhibitor of Lysine-Specific Demethylase 1 (LSD1) that is in phase 1 clinical trials in hematopoietic malignancies. Mice treated with INCB059872 had reduced platelet counts within 4 days of treatment. Here, we used single-cell RNA-seq to study the effects of INCB059872 on hematopoietic progenitor populations within wild-type murine bone marrow. Our results showed that INCB059872 triggered accumulation of megakaryocyte early progenitor cells with gene expression hallmarks of stem cells, which may begin to explain the thrombocytopenia observed in patients treated with LSD1 inhibitors.
