  1. 1. Regulation of PDGFRβ signaling 

    Författare :Piotr Wardęga; Johan Lennartsson; Edvard Smith; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PDGF; HD-PTP; Alix; Cbl; Ub; Fer; Y857; Y771; downregulation; degradation; ubiquitination; activation loop; Cell and molecular biology; Cell- och molekylärbiologi; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Platelet-derived growth factor (PDGF) isoforms, which bind to closely related a- and b-tyrosine kinase receptors, induce migration, proliferation, survival and differentiation of mesenchymal cells. They signal by the active receptor attracting Src homology 2 (SH2) domain containing proteins, which subsequently initiate a set of signaling pathways. LÄS MER

  3. 2. The Role of Membrane Trafficking in G Protein-Coupled Receptor Regulation

    Författare :Johan Enquist; Drug Target Discovery; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; downregulation; recycling; resensitization; desensitization; GPCR; membrane trafficking;

    Sammanfattning : Movements of a receptor in the plasma membrane and within the cell influence receptor function and physiology. I have investigated the role of such movements, generally known as membrane trafficking, in G protein-coupled receptor regulation. LÄS MER

  4. 3. Ubiquitination and Receptor Endocytosis

    Författare :Kaisa Haglund; Carl-Henrik Heldin; Ivan Dikic; Harald Stenmark; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Ubiquitination; receptor tyrosine kinase; endocytosis; Cbl; CIN85; EGFR; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : Protein ubiquitination is an evolutionary conserved mechanism that controls a wide variety of cellular functions. Polyubiquitinated proteins are generally degraded in the proteasome, whereas monoubiquitination controls various other cellular processes, including endocytosis and endosomal sorting. LÄS MER

  5. 4. Regulation and Function of MAP Kinases in PDGF Signaling

    Författare :Glenda Eger; Johan Lennartsson; Carl-Henrik Heldin; Martin Gullberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; PDGFR; MAP kinase; Erk1 2; Erk5; Dusp MKP; NR4A1; cancer; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Platelet-derived growth factor (PDGF) is a family of signaling molecules that stimulates cell growth, survival and migration. PDGF is recognized by specific transmembrane proteins, the PDGF receptors, which relay the signals to the cell activating the Mitogen-activated protein (MAP) kinases and other signaling pathways.

  7. 5. Studies of PDGF receptor signaling in vitro and in vivo

    Författare :Maria Tsioumpekou; Carl-Henrik Heldin; Jean-Baptiste Demoulin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; signaling; cancer; Erk5; kinase; Cbl; ubiquitination; deubiquitinase; pericytes; tumor growth; angiogenesis; low molecular weight inhibitors;

    Sammanfattning : Platelet-derived growth factor receptor (PDGFR) signaling is essential for proliferation, migration and survival of cells of mesenchymal origin; however, its deregulation has been associated with various diseases, including cancer. The aim of this thesis was to clarify the molecular mechanisms of PDGFR signaling regulation. LÄS MER
