  1. 16. Angiogenic mechanims in adipose tissue and tumor

    Författare :Sharon Siew Hoon Lim; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Angiogenesis is involved in the development and progression of many human diseases, including cancer, cardiovascular diseases, chronic inflammation, and metabolic diseases. Despite differences in microenvironment under various pathological settings, angiogenic blood vessels share some common features in numerous diseases. LÄS MER

  3. 17. Effect of Hyaluronan-activation of CD44 on Cell Signaling and Tumorigenesis

    Författare :Lingli Li; Paraskevi Heldin; Raija H. Tammi; Uppsala universitet; []
    Nyckelord :Biomedicine; Hyaluronan; CD44; growth factors; chemokines; tumorigenesis; wound healing; cell signaling; Biomedicin;

    Sammanfattning : Hyaluronan (HA), a structural component in the extracellular matrix (ECM), has been recognized as a signaling molecule. It is important during various biological activities such as embryogenesis, angiogenesis, wound healing and tumor progression. LÄS MER

  4. 18. Redox-regulation of PTPs : mechanisms and impact on PDGFR signaling

    Författare :Markus Dagnell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Protein tyrosine phosphatases (PTPs) are reversibly oxidized upon activation of platelet-derived growth factor receptor beta (PDGFβR). Dys-regulation of the PDGFβR signaling pathway is associated with several diseases, including cancers and cardiovascular disease, and is thus a known driver of disease progression. LÄS MER

  5. 19. Signal Transduction in Malignant Cells – Transformation, Activation and Differentiation

    Författare :Karin Kårehed; Fredrik Öberg; Jan-Ingvar Jönsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; transformation; PDGF; PI3K; Rho-GTPase; U-937; FcγRI; macrophage; Stat1; PKR; NFκB; ATRA; differentiation; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Pathology; Patologi;

    Sammanfattning : All aspects of cell life are regulated by signal transduction mechanisms. This thesis describes the regulatory roles of a few key signal transduction molecules involved in three major biological responses. LÄS MER

  7. 20. Action and interaction of growth factors and regulatory molecules in vascular cells : With special reference to the IGF-I-system

    Författare :Gunilla Dahlfors; Anna Hultgårdh-Nilsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Vascular function is greatly influenced by growth factors and regulatory molecules that can interact with each other in a complex pattern in the vascular wall. In this thesis we studied how different substances of special interest in the pathogenesis of vascular disease interact and regulate each other's expressions in endothelial cells and vascular smooth muscle cells (VSMCs).
