• Epac1 null mice have nephrogenic diabetes insipidus with deficient corticopapillary osmotic gradient and weaker collecting duct tight junctions 

      Åsrud, Kathrine Sivertsen; Bjørnstad, Ronja; Kopperud, Reidun Kristin; Pedersen, Line; van der Hoeven, Barbara; Karlsen, Tine Veronica; Rygh, Cecilie Brekke; Curry, Fitz-Roy; Bakke, Marit; Reed, Rolf K.; Tenstad, Olav; Døskeland, Stein Ove (Journal article; Peer reviewed, 2020)
      Aim The cAMP‐mediator Epac1 (RapGef3) has high renal expression. Preliminary observations revealed increased diuresis in Epac1−/− mice. We hypothesized that Epac1 could restrict diuresis by promoting transcellular collecting ...
    • Fibroblast α11β1 Integrin Regulates Tensional Homeostasis in Fibroblast/A549 Carcinoma Heterospheroids 

      Lu, Ning; Karlsen, Tine Veronica; Reed, Rolf K.; Kusche-Gullberg, Marion; Gullberg, Donald (Peer reviewed; Journal article, 2014-07-30)
      We have previously shown that fibroblast expression of α11β1 integrin stimulates A549 carcinoma cell growth in a xenograft tumor model. To understand the molecular mechanisms whereby a collagen receptor on fibroblast can ...
    • High-salt diet causes osmotic gradients and hyperosmolality in skin without affecting interstitial fluid and lymph 

      Nikpey Esfahlan, Elham; Karlsen, Tine Veronica; Rakova, Natalia; Titze, Jens M.; Tenstad, Olav; Wiig, Helge (Peer reviewed; Journal article, 2017-04)
      The common notion is that the body Na+ is maintained within narrow limits for fluid and blood pressure homeostasis. Several studies have, however, shown that considerable amounts of Na+ can be retained or removed from the ...
    • Impaired lymphatic function accelerates cancer growth 

      Steinskog, Eli Sihn Samdal; Sagstad, Solfrid Johanne; Wagner, Marek; Karlsen, Tine Veronica; Yang, Ning; Markhus, Carl Erik Nordvik; Yndestad, Synnøve; Wiig, Helge; Eikesdal, Hans Petter (Peer reviewed; Journal article, 2016-06-13)
      Increased lymphangiogenesis is a common feature of cancer development and progression, yet the influence of impaired lymphangiogenesis on tumor growth is elusive. C3HBA breast cancer and KHT-1 sarcoma cell lines were ...
    • Increased microvascular permeability in mice lacking Epac1 (Rapgef3) 

      Kopperud, Reidun Kristin; Rygh, Cecilie Brekke; Karlsen, Tine Veronica; Krakstad, Camilla; Kleppe, Rune; Høivik, Erling Andre; Bakke, Marit; Tenstad, Olav; Selheim, Frode; Liden, Åsa; Madsen, Lise; Pavlin, Tina; Taxt, Torfinn; Kristiansen, K.; Curry, FE; Reed, Rolf K.; Doskeland, Stein Ove (Peer reviewed; Journal article, 2017-02)
      Aim: Maintenance of the blood and extracellular volume requires tight control of endothelial macromolecule permeability, which is regulated by cAMP signalling. This study probes the role of the cAMP mediators rap guanine ...
    • Interstitial IgG antibody pharmacokinetics assessed by combined in vivo- and physiologically-based pharmacokinetic modelling approaches 

      Eigenmann, Miro Julian; Karlsen, Tine Veronica; Krippendorff, Ben-Fillippo; Tenstad, Olav; Fronton, Ludivine; Otteneder, Michael B.; Wiig, Helge (Peer reviewed; Journal article, 2017-12)
      For most therapeutic antibodies, the interstitium is the target space. Although experimental methods for measuring antibody pharmacokinetics (PK) in this space are not well established, thus making quantitative assessment ...
    • The notochord in Atlantic salmon (Salmo salar L.) undergoes profound morphological and mechanical changes during development 

      Kryvi, Harald; Rusten, Iselin; Fjelldal, Per Gunnar; Nordvik, Kari; Totland, Geir Kåre; Karlsen, Tine Veronica; Wiig, Helge; Long, John H. (Peer reviewed; Journal article, 2017-11)
      We present the development of the notochord of the Atlantic salmon (Salmo salar L.), from early embryo to sexually mature fish. Over the salmon's lifespan, profound morphological changes occur. Cells and gross structures ...
    • Pharmacokinetics and pharmacodynamics of t-cell bispecifics in the tumour interstitial fluid 

      Eigenmann, Miro Julian; Karlsen, Tine Veronica; Wagner, Marek; Tenstad, Olav; Weinzierl, Tina; Fauti, Tanja; Grimm, Hans Peter; Skogstrand, Trude; Klein, Christian; Sam, Johannes; Umana, Pablo; Bacac, Marina; Wiig, Helge; Walz, Antje-Christine (Journal article; Peer reviewed, 2021)
      The goal of this study is to investigate the pharmacokinetics in plasma and tumour interstitial fluid of two T-cell bispecifics (TCBs) with different binding affinities to the tumour target and to assess the subsequent ...
    • Stromal integrin α11-deficiency reduces interstitial fluid pressure and perturbs collagen structure in triple-negative breast xenograft tumors 

      Smeland, Hilde Ytre-Hauge; Lu, Ning; Karlsen, Tine Veronica; Salvesen, Gerd Signe; Reed, Rolf K.; Stuhr, Linda Elin Birkhaug (Peer reviewed; Journal article, 2019-03-15)
      Background: Cancer progression is influenced by a pro-tumorigenic microenvironment. The aberrant tumor stroma with increased collagen deposition, contractile fibroblasts and dysfunctional vessels has a major impact on the ...
    • Time course of decompensation after angiotensin II and high-salt diet in Balb/CJ mice suggests pulmonary hypertension-induced cardiorenal syndrome 

      Becirovic-Agic, Mediha; Jönsson, Sofia; Tveitarås, Maria Kathrine; Skogstrand, Trude; Karlsen, Tine Veronica; Liden, Åsa; Leh, Sabine Maria; Ericsson, Madelene; Nilsson, Stefan K.; Reed, Rolf K.; Hultström, Michael (Peer reviewed; Journal article, 2019-05-01)
      The genetic background of a mouse strain determines its susceptibility to disease. C57BL/6J and Balb/CJ are two widely used inbred mouse strains that we found react dramatically differently to angiotensin II and high-salt ...
