2. 21. Cyclin A1 Expression and Regulation in Hematopoietic and Leukemic Cells

   Author : Jenny Ekberg; Malmö Patologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; General pathology; pathological anatomy; Patologi allmän ; patologisk anatomi; onkologi; Cytologi; cancerology; oncology; Cytology; AML; cyclin A1; apoptosis; cell cycle regulation;

   Abstract : Increased expression of the cell cycle regulatory protein cyclin A1 has previously been detected in patients with acute myeloid leukemia (AML) and targeted overexpression of cyclin A1 in a transgenic mouse model initiated AML. The aim of this thesis was to further study the expression and regulation of cyclin A1 in hematopoietic cells. READ MORE

4. 22. Gene Expression Studies of Hematologic Malignacies

   Author : Anna Andersson; Avdelningen för klinisk genetik; []
   Keywords : 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;

   Abstract : 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.

5. 23. THE HYPOXIC HEMATOPOIETIC STEM CELL NICHE Consequences of Hypoxia-induced Transcription on Stem Cell Fate

   Author : Matilda Rehn; Avdelningen för molekylärmedicin och genterapi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic Stem Cells; Stem Cell Niche; Hypoxia; Hypoxia-Inducible Factor; Vegfa.;

   Abstract : Hematopoiesis is the process of blood formation that originates with the hematopoietic stem cell (HSC), a cell type that is responsible for the life-long supply of mature blood cells. HSCs are defined by their ability to self-renew as well as giving rise to differentiated cells of all blood lineages. READ MORE

6. 24. Neural Stem and Progenitor Cells : Cellular Responses to Known and Novel Factors

   Author : Jimmy Larsson; Karin Forsberg-Nilsson; Ola Hermanson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural stem cell; differentiation; proliferation; migration; PDGF; SCF; NRBP2; medulloblastoma; Biochemistry; Biokemi; Medical Biochemistry; Medicinsk biokemi;

   Abstract : Neural stem cell self-renewal and differentiation are tightly regulated events during CNS development, leading to cell division into new neural stem cells or the formation of neurons and glial cells. This thesis focuses on the cellular responses induced by known and novel factors in neural stem and progenitor cells (NSPCs). READ MORE

7. 25. A novel principle for immunomodulator delivery with hematopoietic cells as vehicles Focus on soluble TNF-receptor gene expression, targeting to secretory lysosomes and regulated secretion

   Author : Ying Gao; Avdelningen för hematologi och transfusionsmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellulära vätskor; extracellular fluids; Hematologi; Medicin människa och djur ; Haematology; Medicine human and vertebrates ; neutrophil; granule; secretory lysosome; sorting; phagocytosis; degranulation.; mast cell; hematopoietic cell; inflammation; soluble TNF receptor;

   Abstract : The goal of this research is to use hematopoietic cells as vehicles for targeting transgenic immunomodulators to the inflammatory sites. The work presented was focused on the anti-inflammatory soluble TNF receptor. A transmembrane soluble TNF receptor (sTNFR1) construct was expressed in hematopoietic cell lines. READ MORE
