• Cleavage of the urokinase receptor (uPAR) on oral cancer cells: Regulation by transforming growth factor - beta1 (TGF-beta1) and potential effects on migration and invasion 

      Magnussen, Synnøve; Hadler-Olsen, Elin Synnøve; Costea, Daniela Elena; Berg, Eli; Cavalcanti Jacobsen, Cristiane de Albuquerque; Mortensen, Bente; Salo, Tuula; Martinez, Inigo Zubiavrre; Winberg, Jan-Olof; Uhlin-Hansen, Lars; Svineng, Gunbjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-19)
      Background: Urokinase plasminogen activator (uPA) receptor (uPAR) is up-regulated at the invasive tumour front of human oral squamous cell carcinoma (OSCC), indicating a role for uPAR in tumour progression. We previously observed elevated expression of uPAR at the tumour-stroma interface in a mouse model for OSCC, which was associated with increased proteolytic activity. The tumour microenvironment ...
    • The marine natural product mimic MPM-1 is cytolytic and induces DAMP release from human cancer cell lines 

      von Hofsten, Susannah; Paulsen, Marianne Hagensen; Magnussen, Synnøve; Ausbacher, Dominik; Kranz, Mathias; Bayer, Annette; Strøm, Morten Bøhmer; Berge, Gerd (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-16)
      Bioprospecting contributes to the discovery of new molecules with anticancer properties. Compounds with cytolytic activity and the ability to induce immunogenic cell death can be administered as intratumoral injections with the aim to activate anti-tumor immune responses by causing the release of tumor antigens as well as damage-associated molecular patterns (DAMPs) from dying cancer cells. In ...
    • Nephronectin is Correlated with Poor Prognosis in Breast Cancer and Promotes Metastasis via its Integrin-Binding Motifs 

      Steigedal, Tonje S.; Toraskar, Jimita; Redvers, Richard P.; Valla, Marit; Magnussen, Synnøve; Bofin, Anna M.; Opdahl, Signe; Lundgren, Steinar; Eckhardt, Bedrich L.; Lamar, John M.; Doherty, Judy; Hynes, Richard O.; Anderson, Robin L.; Svineng, Gunbjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-11)
      Most cancer patients with solid tumors who succumb to their illness die of metastatic disease. While early detection and improved treatment have led to reduced mortality, even for those with metastatic cancer, some patients still respond poorly to treatment. Understanding the mechanisms of metastasis is important to improve prognostication, to stratify patients for treatment, and to identify new ...
    • Nephronectin mediates p38 MAPK‐induced cell viability via its integrin binding enhancer motif 

      Toraskar, Jimita Prashant; Magnussen, Synnøve; Chawla, Konika; Svineng, Gunbjørg; Steigedal, Tonje S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-30)
      Nephronectin (NPNT) is an extracellular matrix (ECM) protein involved in kidney development. We recently reported intracellular NPNT as a potential prognostic marker in breast cancer and that NPNT promotes metastasis in an integrin‐dependent manner. Here, we used reverse‐phase protein array (RPPA) to analyze NPNT‐triggered intracellular signaling in the 66cl4 mouse breast cancer cell line. The results ...
    • Oral Squamous Cell Carcinoma - Role of the Plasminogen Activation System in Tumour Progression. 

      Magnussen, Synnøve (Doctoral thesis; Doktorgradsavhandling, 2015-01-30)
      Oral squamous cell carcinoma (OSCC) is an aggressive and unpredictable cancer with a high tendency to recur and metastasise. Despite increasing efforts to improved treatment, the 5-year survival rate is still low. We discovered that low expression levels of the urokinase plasminogen activator receptor (uPAR) and the plasminogen activator inhibitor-1 (PAI-1) two proteins normally involved in the ...
    • Plectin as a prognostic marker in non-metastatic oral squamous cell carcinoma 

      Rikardsen, Oddveig G; Magnussen, Synnøve; Svineng, Gunbjørg; Hadler-Olsen, Elin Synnøve; Uhlin-Hansen, Lars; Steigen, Sonja Eriksson (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-26)
      <p>Background: Oral squamous cell carcinoma (OSCC) is associated with a poor 5-year survival rate. In general, patients diagnosed with small tumors have a fairly good prognosis, but some small tumors have an aggressive behavior leading to early death. There are at present no reliable prognostic biomarkers for oral cancers. Thus, to optimize treatment for the individual patient, there is a need ...
    • Tumour Microenvironments Induce Expression of Urokinase Plasminogen Activator Receptor (uPAR) and Concomitant Activation of Gelatinolytic Enzymes 

      Magnussen, Synnøve; Hadler-Olsen, Elin Synnøve; Latysheva, Nadezhda; Pirila, Emma; Steigen, Sonja Eriksson; Hanes, Robert; Salo, Tuula; Winberg, Jan-Olof; Uhlin-Hansen, Lars; Svineng, Gunbjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
    • Urokinase Plasminogen Activator Receptor (uPAR) and Plasminogen Activator Inhibitor-1 (PAI-1) are potential predictive biomarkers in early stage Oral Squamous Cell Carcinomas (OSCC)
