    • Molecular targets and biological effects of PAX6 in lung cancer 

      Johannessen, Charles (Master thesis; Mastergradsoppgave, 2013-05-15)
      Lung cancer is by far the leading cause of cancer-related mortality worldwide regardless of sex, and has a dismal overall 5-year survival rate of approximately 15%. More than 85% of all lung cancers are non-small cell lung cancer (NSCLC), and about 50% of these are adenocarcinomas. Targeted treatment has shown promising results in treating certain types of NSCLC, but the overall survival is still ...

      Granaas, Magnus Løkke (Master thesis; Mastergradsoppgave, 2013-05-15)
      PDE5 is a member of the superfamily of phosphodiesterases, and it is identified as the main mechanism for breakdown of cGMP in mammals. Sildenafil is a well-known inhibitor of the PDE5 enzyme and it is also shown that sildenafil inhibits the ABCC5 transporter pump. ABCC5 is a member of the superfamily of ABC-transporters, and identified as an important transporter for mediating the cellular efflux ...

    • Partial characterization of predicted ABCC5 inhibitors by the aid of human erythrocyte inside-out vesicles 

      Ørvoll, Elin (Master thesis; Mastergradsoppgave, 2011-06-24)
      ABCC5 is a member of the superfamily of ABC-transporters, and it has been identified as an efflux transporter of cGMP. This transporter is also involved in export of antibiotic and cytostatic drugs from target cells, and as such represents a challenge in treatment of cancer and infectious diseases. In order to find inhibitors to ABCC5 mediated drug efflux, compounds predicted as potent inhibitors ...

    • Silencing of Renal DNaseI in Murine Lupus Nephritis Imposes Exposure of Large Chromatin Fragments and Activation of Toll Like Receptors and the Clec4e 

      Thiyagarajan, Dhivya; Fismen, Silje; Seredkina, Natalya; Jacobsen, Søren; Elung-Jensen, Thomas; Kamper, Anne-Lise; Fenton, Christopher Graham; Rekvig, Ole Petter; Mortensen, Elin Synnøve (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Recent studies demonstrate that transformation of mild lupus nephritis into end-stage disease is imposed by silencing of renal DNaseI gene expression in (NZBxNZW)F1 mice. Down-regulation of DNaseI results in reduced chromatin fragmentation, and in deposition of extracellular chromatin-IgG complexes in glomerular basement membranes in individuals that produce IgG anti-chromatin antibodies. The main ...
