  1. 1. FLT3 receptor in normal and malignant hematopoiesis

    Författare :Shabnam Kharazi; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FLT3-ITD; FLT3; lineage commitment; acute myeloid leukemia; myeloprolifetaive disease; hematopoietic stem cell;

    Sammanfattning : All hematopoietic cells originate from hematopoietic stem cells (HSCs) residing in the bone marrow (BM). The classical model of hematopoietic lineage commitment, that has been the prevailing model for hematopoiesis, proposes that the first lineage commitment step of HSCs and progenitors results in a strict separation of myelopoiesis and lymphopoiesis.

  3. 2. Regulation of Apoptosis in Hematopoietic Progenitor Cells: Involvement of Different Signaling Pathways

    Författare :Maria Kraft; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytokines; apoptosis; cell cycle; c-Kit; Flt3; Flt3-ITD; Akt; Bcl-2; FoxO3; mouse; hematopoiesis; progenitor;

    Sammanfattning : Proliferation, differentiation, and survival of hematopoietic stem cells and multipotent progenitor cells are regulated by cytokines and cell-cell interactions. Kit ligand (KL) and Flt3 ligand (FL) have pleiotropic effects, promotes survival, but are nonredundant. LÄS MER

  4. 3. Studies on signaling pathways induced by FLT3, an important oncogene in AML

    Författare :Elena Razumovskaya; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FLT3; AML; RTK; oncogene; ERK5; hematopoiesis;

    Sammanfattning : FLT3, a receptor tyrosine kinase, is expressed in hematopoietic progenitor cells. FLT3-ITD (internal tandem duplication) and D835 mutations are found in approximately 30% and 7% of Acute Myeloid Leukemia (AML) patients respectively, and correlate with a poor prognosis, thus making the mutated receptor a potential therapeutic target.

  5. 4. Role of FLT3 in Acute Myeloid Leukemia: Molecular mechanisms and Therapeutic opportunities

    Författare :Sausan Moharram; Avdelningen för translationell cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LEUKEMIA; AML; Mutations; FLT3; Signlaing;

    Sammanfattning : Acute myeloid leukemia (AML) is a highly heterogeneous blood disease which is characterized by different mutations and chromosomal rearrangements. Nearly 60% of genetic alterations have been found in AML patients involve in signaling pathways including signaling of tyrosine kinase receptor FLT3. LÄS MER

  7. 5. Expression and role of the cytokine tyrosine kinase receptor flt3 in early hematopoiesis

    Författare :Jörgen Adolfsson; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematologi; extracellulära vätskor; extracellular fluids; Haematology; flt3; cytokine; Hematopoiesis; stem cells;

    Sammanfattning : Mature blood cells are crucial for life, but they have a short lifetime and thus have to be replaced. These mature blood cells are produced by lineage restricted progenitors, which themselves are generated by rare multipotent hematopoietic stem cells (HSCs) in a highly dynamic process called hematopoiesis.
