  1. 6. 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

  3. 7. Regulation of Polyamine Analogue-Induced Apoptosis in Human Breast Cancer Cells

    Författare :Martina Holst; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cancer; Animal physiology; Djurfysiologi; Pharmacological sciences; pharmacognosy; pharmacy; onkologi; Cytologi; cancerology; oncology; Cytochrome c; Cytology; Bcl-2; Mitochondrial respiration; Apoptosis; Human breast cancer cells; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Social medicine; Socialmedicin; samhällsmedicin; Mitochondria; Polyamine analogues;

    Sammanfattning : Apoptosis is a defined process for cells to commit suicide through a set of biochemical and morphological cell changes. Activated apoptotic signals converge on the mitochondria, leading to permeabilization of mitochondrial membranes and release of different apoptosis regulatory proteins into the cytosol. LÄS MER

  4. 8. On the Role of Polyamines in Apoptosis

    Författare :Cecilia Hegardt; Bröstcancer-genetik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SSAT; DENSPM; spermine; polyamines; mitochondrial membrane potential; cytochrome c; caspase; flow cytometry; Jurkat cells; mouse thymocytes; thymus in vivo; programmed cell death; Dexamethasone-induced apoptosis; Fas-induced apoptosis; AdoMetDC; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; Clinical biology; Klinisk biologi; Animal physiology; Djurfysiologi;

    Sammanfattning : Apoptosis is a kind of death that is best described as cellular suicide and it is important for normal tissue homeostasis. The process can be induced by a number of different stimuli and the dying cell goes through a defined pathway terminating in typical biochemical and morphological alterations of the cell. LÄS MER

  5. 9. Modulatory role of IL-17 in airway inflammation

    Författare :Elin Silverpil; Göteborgs universitet; []
    Nyckelord :Respiratory medicine; Lung; IL-17; IL-23; Macrophages; Neutrophils; T cells; Apoptosis; Phagocytosis; Airways;

    Sammanfattning : IL-17 orchestrates the accumulation of neutrophils to sites of infection and the release of microbicidal substances, and therefore plays a critical role in the innate immune response to infection. IL-17 is also involved in certain chronic inflammatory diseases in which dysfunctional control of neutrophil accumulation and turnover constitutes an important pathogenic factor. LÄS MER

  7. 10. Radiation-induced apoptosis in human lymphocytes : studies on expression, function and effects of different radiation qualities

    Författare :Annelie Meijer; Fabrizio Palitti; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Apoptosis; clonogenic survival; growth factors; chromosomal aberrations CA ; low dose-rate LDR ; linear energy transfer LET ; relative biological effectiveness RBE ; radio sensitivity; ataxia telangiectasia A-T ; Physical Biology; fysikalisk biologi;

    Sammanfattning : We are constantly exposed to radiation. Radiation causes damage to our cells. By the removal of damaged and unwanted cells, apoptosis is considered to be one of the most indispensable defence processes for a multi-cellular organism. LÄS MER
