  1. 11. Translational Aspects of Erythropoietin Receptor and Hypoxia-Inducible Factors in Breast Cancer

    Författare :Anna-Maria Larsson; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast Cancer; Anemia; Hypoxia; Erythropoietin EPO ; EPO receptor EPOR ; Estrogen Receptor ER ; Hypoxia-Inducible Factors HIFs ; Tamoxifen Response; Proliferation;

    Sammanfattning : The main function of erythropoietin (EPO) is in hematopoiesis where EPO stimulates increased proliferation, survival and differentiation of erythrocytic precursors in response to hypoxia. The EPO effect is mediated via binding to the EPO receptor (EPOR), which induces activation of different intracellular signaling pathways. LÄS MER

  3. 12. Electrical Bioimpedance Cerebral Monitoring : Effects of Hypoxia

    Författare :Fernando Seoane; Kaj Lindecrantz; Orjan Martinsen; University of Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electrical bioimpedance spectroscopy is one way to study the electrical properties of biological matter. Different applications of electrical bioimpedance measurements have already been used in both research and clinical scenarios i.e. impedance plethysmography, total body water contents, etc. LÄS MER

  4. 13. Effects of hypoxia on macrophage function in atherosclerosis

    Författare :Ellen Knutsen Rydberg; Göteborgs universitet; []
    Nyckelord :atherosclerosis; hypoxia; macrophage; IL-8; oxidized LDL; oxysterols; 15-lipoxygenase-2;

    Sammanfattning : Atherosclerosis is a complex disease, which affects large and medium sized arteries and is characterized by an arterial wall thickening. A constant supply of oxygen is needed to maintain cell functions in the atherosclerotic plaque. The oxygen distribution to the cells in the arterial wall depends on diffusion. LÄS MER

  5. 14. Hypoxia-induced phenotypic modulation of human neuroblastoma cells

    Författare :Linda Holmquist Mengelbier; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; reoxygenation; HIF-2a; HIF-1a; differentiation; hypoxia; neuroblastoma;

    Sammanfattning : Neuroblastoma is a childhood tumour derived from cells of the sympathetic nervous system, which are arrested at low differentiation stages. Low differentiation stage and high tumour stage correlate to poor outcome. LÄS MER

  7. 15. Hypoxia inducible factor-1α in renal cell carcinoma

    Författare :Anders Lidgren; Börje Ljungberg; Torgny Rasmuson; Kjell Grankvist; Anders Bergh; Per-Uno Malmström; Umeå universitet; []

    Sammanfattning : Hypoxia Inducible Factor-1α in Renal Cell Carcinoma Departments of Surgical and Perioperative Sciences, Urology and Andrology; Radiation Sciences, Oncology; Medical Biosciences, Pathology; and Medical Biosciences, Clinical Chemistry, Umeå University, Umeå, Sweden Background: Renal cell carcinoma (RCC) accounts for approximately 2-3% of all human cancers. A distinguished feature of RCC is vascularisation and among the three dominating RCC types conventional RCC (cRCC) generally is more vascularised than papillary RCC (pRCC) and chromophobe RCC (chRCC).
