  1. 21. Growth regulation in sarcomas : studies in vivo and in cell culture

    Författare :Avni Abdiu; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Sarcomas are malignant tumors of mesenchymal origin, and can arise in soft-tissue and in bones. It has been suggested that the abnormal growth regulation in sarcoma cells may be due to an autocrine mechanism, in which the cells are stimulated by an endogenous production of growth factors.

  2. 22. Biological activities of novel platelet-derived growth factors, PDGF-C and PDGF-D

    Författare :Annica Pontén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Platelet-derived growth factors (PDGFs) belong to the PDGF/VEGF (vascular endothelial growth factor) family of growth factors. Members of this family share a common structural feature, a conserved PDGF/VEGF homology domain, containing eight invariant cysteine residues. LÄS MER

  3. 23. Developmental origin and molecular regulation of vascular smooth muscle cells

    Författare :Per Wasteson; Göteborgs universitet; []
    Nyckelord :smooth muscle cell; aorta; cell origin; lateral plate mesoderm; paraxial mesoderm; lipoma preferred partner; serum response factor; neointimal hyperplasia; angiotensin II; platelet-derived growth factor-B;

    Sammanfattning : Several pathologies of the vascular system have been suggested to be dependent on the smooth muscle cells (SMCs) that build up the vessel wall. Aortic SMCs have been proposed to derive from lateral plate mesoderm. LÄS MER

  4. 24. Current Medical Treatment of Endocrine Pancreatic Tumors and Future Aspects

    Författare :Marie-Louise Fjällskog; Morten Vatn; Uppsala universitet; []
    Nyckelord :Medical sciences; pancreatic tumors; somatostatin analogs; cisplatin; etoposide; somatostatin receptors; immunohistochemistry; tyrosine kinase receptors; platelet-derived growth factors receptors PDGFRs ; c-kit; epidermal growth factor receptor EGFR ; MEDICIN OCH VÅRD; alfa-interferon; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : We treated 16 patients with somatostatin analogs combined with α-interferon and achieved a biochemical and/or radiological response in 56% (median duration 22 months). We consider this treatment a good alternative for patients who fail during chemotherapy or who do not want to/cannot receive cytotoxic drugs. LÄS MER

  5. 25. 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
