  1. 1. Importance of Hyaluronan-CD44 Signaling in Tumor Progression : Crosstalk with TGFβ and PDGF-BB Signaling

    Författare :Helena Porsch; Paraskevi Heldin; Véronique Orian-Rousseau; Uppsala universitet; []
    Nyckelord :extracellular matrix; growth factor; hyaluronan synthase; hyaluronidase; epithelial-mesenchymal transition; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : In order for solid tumors to metastasize, tumor cells must acquire the ability to invade the surrounding tissue and intravasate into blood- or lymph vessels, survive in the circulation and then extravasate at a distant site to form a new tumor. Overexpression of the glycosaminoglycan hyaluronan, and its adhesion receptor CD44, correlate with breast cancer progression. LÄS MER

  3. 2. Collagen-binding integrin α2β1 activity in vivo and in vitro : Effects of platelet-derived growth factor-BB

    Författare :Karina Åhlén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Integrin α2β1; PDGF-BB; fibroblast; interstitial fluid pressure; cytoskeletal interaction; phosphatidylinositol 3-kinase; [Ca2 ]i; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : The expression of integrins by two cell clones from a rat colon carcinoma was investigated. Cloned cells that gave rise to regressive tumors, but not cells that gave rise to progressive, lethal, tumors, adhered to interstitial collagens through the integrin α2β1, although both cell types expressed it.

  4. 3. Intra- and Extracellular Modulation of Integrin-directed Connective Tissue Cell Contraction

    Författare :Tijs van Wieringen; Kristofer Rubin; Anders Arner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interstitial fluid pressure; PDGF-BB; bacterial proteins; αVβ3 integrin; cytoskeleton; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : All blood vessels in the microvasculature are embedded in loose connective tissue, which regulates the transport of fluid to and from tissues. The intersti-tial fluid pressure (IFP) is one of the forces that control this transport. LÄS MER

  5. 4. Regulation of Hyaluronan Synthesis and Signaling via CD44 in Cancer

    Författare :Merima Mehić; Paraskevi Heldin; Carl-Henrik Heldin; Liliana Schaefer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyaluronan; CD44; TGFβ; PDGF-BB; cancer; signaling; hyaluronan synthase; epithelial-mesenchymal transition; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi; Medical Science; Medicinsk vetenskap;

    Sammanfattning : Hyaluronan is a ubiquitous glycosaminoglycan which is an important constituent of the extracellular matrix (ECM). In addition to organizing the extracellular matrix and regulating tissue homeostasis, hyaluronan, by binding to its main cell surface receptor CD44, is involved in intracellular signaling pathways regulating major cellular processes during development, wound healing, inflammation and cancer.

  7. 5. Angiogenic growth factors : mechanism of action and function in vascular development

    Författare :Charlotte Rolny; Andrius Kazlauskas; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; PDGF-BB; VEGF; angiogenesis; hypoxia; migration; heparin; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Molecular Medicine; molekylär medicin genetik och patologi ;

    Sammanfattning : The mature vascular system is composed of a network of blood vessels organized into arteries, capillaries, and veins. The vessels are composed of endothelial cells surrounded by smooth muscle cells and embedded in a specialized basement membrane. LÄS MER
