  1. 1. Gene Expression Studies of Hematologic Malignacies

    Författare :Anna Andersson; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Haematology; cancer; onkologi; Cytologi; oncology; Cytology; acute myeloid leukemia; acute lymphoblastic leukemia; normal hematopoietic cells; cDNA microarray; gene expression profiling; hematopoiesis; pediatric leukemia; fusion gene; Pediatrics; Pediatri; Clinical genetics; Klinisk genetik; cancerology; Hematologi; extracellulära vätskor;

    Sammanfattning : The general aim of this thesis was to characterize hematologic malignancies using gene expression profiling in order to obtain an improved classification and to study deregulated transcriptional networks in leukemia. In the first study (Article I), the gene expression profiles of hematologic cell lines were analyzed to investigate whether such cell lines maintain expression profiles that are characteristic of their primary genetic changes.

  3. 2. Identification and Characterization of Stem Cells in Preleukemia and Leukemia

    Författare :Lars Nilsson; Stamcellscentrum (SCC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haematology; extracellulära vätskor; Hematologi; Philadelphia chromosome; acute lymphoblastic leukemia; polycytemia vera; 5q- syndrome; myelodysplastic syndromes; self-renewal; preleukemia; Hematopoietic stem cells; leukemic stem cells; extracellular fluids;

    Sammanfattning : Hematopoietic stem cells (HSCs) are responsible for the daily and life long production of large numbers of mature blood cells through highly regulated self-renewal and multilineage capabilities. Leukemias on the other hand, are characterized by a clonal, dysregulated, lineage skewed proliferation and impaired differentiation as the result of multiple accumulated genetic events. LÄS MER

  4. 3. Molecular and functional studies of the BCR/ABL1 fusion gene

    Författare :Petra Johnels; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Hematologi; Haematology; onkologi; Cytologi; cancerology; oncology; Cytology; gene expression profiling; acute lymphoblastic leukemia; chronic myeloid leukemia; Ph chromosome; BCR ABL; extracellulära vätskor; Clinical genetics; Klinisk genetik; cancer;

    Sammanfattning : The BCR/ABL1 fusion gene is associated with chronic myeloid leukemia and a subgroup of acute lymphoblastic leukemia. The general aim of this thesis was to increase the understanding of BCR/ABL1-induced leukemogenesis by molecular and functional studies of this fusion gene. LÄS MER

  5. 4. 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.

  7. 5. Identification of intrinsic regulators in normal and malignant human hematopoiesis. An RNA-interference approach

    Författare :Roman Galeev; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cell; RNA interference; Acute myeloid leukemia; myelodysplastic syndrome; genetic screens; next generation sequencing; genetic regulators;

    Sammanfattning : Bildandet av blodceller, hematopoesen, utgår från ett litet antal av de så kallade hematopoetiska stamceller som sitter i vår benmärg. Dessa celler har förmågan att ge upphov till alla mogna blodcellstyper av de tre hematopoetiska linjerna, samtidigt som de genom celldelning bibehåller sin egna mängd. LÄS MER
