AML1/ETO accelerates cell migration and impairs cell-to-cell adhesion and homing of hematopoietic stem/progenitor cells
The AML1/ETO fusion protein found in acute myeloid leukemias functions as a transcriptional regulator by recruiting co-repressor complexes to its DNA binding site. In order to extend the understanding of its role in preleukemia, we expressed AML1/ETO in a murine immortalized pluripotent hematopoietic stem/progenitor cell line, EML C1, and found that genes involved in functions such as cell-to-c...
متن کاملThe AML1-ETO fusion protein promotes the expansion of human hematopoietic stem cells.
The acute myelogenous leukemia-1 (AML1)-ETO fusion protein is generated by the t(8;21), which is found in 40% of AMLs of the French-American-British M2 subtype. AML1-ETO interferes with the function of the AML1 (RUNX1, CBFA2) transcription factor in a dominant-negative fashion and represses transcription by binding its consensus DNA-binding site and via protein-protein interactions with other t...
متن کاملAML1-ETO reprograms hematopoietic cell fate by downregulating scl expression.
AML1-ETO is one of the most common chromosomal translocation products associated with acute myelogenous leukemia (AML). Patients carrying the AML1-ETO fusion gene exhibit an accumulation of granulocyte precursors in the bone marrow and the blood. Here, we describe a transgenic zebrafish line that enables inducible expression of the human AML1-ETO oncogene. Induced AML1-ETO expression in embryon...
متن کاملSpecification of Hemato-Endothelial-Like Structures and Generation of Hematopoietic Progenitor Cells from Human Pluripotent Stem Cells
Background and purpose: Human pluripotent stem cells (hPSCs) with the ability to differentiate into adult cells have provided a new perspective for treatment of some diseases. But, the efficiency of differentiation methods to generate hematopoietic progenitor cells (HPCs) is faced with multiple challenges. In the present study, we investigated the formation of hemato-endothelial-like structure...
متن کاملHoxb4 transduction down-regulates Geminin protein, providing hematopoietic stem and progenitor cells with proliferation potential.
Retrovirus-mediated transduction of Hoxb4 enhances hematopoietic stem cell (HSC) activity and enforced expression of Hoxb4 induces in vitro development of HSCs from differentiating mouse embryonic stem cells, but the underlying molecular mechanism remains unclear. We previously showed that the HSC activity was abrogated by accumulated Geminin, an inhibitor for the DNA replication licensing fact...
