• Altered DNA methylation profile in Norwegian patients with Autoimmune Addison’s Disease 

      Bjånesøy, Trine Elholm; Andreassen, Bettina Kulle; Bratland, Eirik; Reiner, Andrew Henry; Islam, Shahinul; Husebye, Eystein Sverre; Bakke, Marit (Peer reviewed; Journal article, 2014-03-22)
      Autoimmune Addison's Disease (AAD) is an endocrine and immunological disease of uncertain pathogenesis resulting from the immune system's destruction of the hormone producing cells of the adrenal cortex. The underlying ...
    • Computational characterization of modes of transcriptional regulation of nuclear receptor genes 

      Sharma, Yogita; Chilamakuri, Chandra Sekhar Reddy; Bakke, Marit; Lenhard, Boris (Peer reviewed; Journal article, 2014-02-13)
      Background: Nuclear receptors are a large structural class of transcription factors that act with their co-regulators and repressors to maintain a variety of biological and physiological processes such as metabolism, ...
    • 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 ...
    • Epac1-deficient mice have bleeding phenotype and thrombocytes with decreased GPIbβ expression 

      Nygaard, Gyrid; Herfindal, Lars; Åsrud, Kathrine Sivertsen; Bjørnstad, Ronja; Kopperud, Reidun Kristin; Oveland, Eystein; Berven, Frode; Myhren, Lene Elisabeth; Høivik, Erling Andre; Lunde, Turid Helen Felli; Bakke, Marit; Døskeland, Stein Ove; Selheim, Frode (Peer reviewed; Journal article, 2017)
      Epac1 (Exchange protein directly activated by cAMP 1) limits fluid loss from the circulation by tightening the endothelial barrier. We show here that Epac1−/− mice, but not Epac2−/− mice, have prolonged bleeding time, ...
    • Fusion pore regulation by cAMP/Epac2 controls cargo release during insulin exocytosis 

      Gucek, Alenka; Gandasi, Nikhil R.; Omar-Hmeadi, Muhmmad; Bakke, Marit; Doskeland, Stein Ove; Tengholm, Anders; Barg, Sebastian (Peer reviewed; Journal article, 2019-05-20)
      Regulated exocytosis establishes a narrow fusion pore as initial aqueous connection to the extracellular space, through which small transmitter molecules such as ATP can exit. Co-release of polypeptides and hormones like ...
    • 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 ...
    • Long-term consumption of an obesogenic high fat diet prior to ischemia-reperfusion mediates cardioprotection via Epac1-dependent signaling 

      Edland, Fridtjov; Wergeland, Anita; Kopperud, Reidun Kristin; Åsrud, Kathrine Sivertsen; Hoivik, Erling A; Witsø, Solveig Lund; Æsøy, Reidun; Madsen, L; Kristiansen, K.; Bakke, Marit; Doskeland, Stein Ove; Jonassen, Anne K (Peer reviewed; Journal article, 2016-11-28)
      Background: Obesity is still considered a risk factor for cardiovascular disease, although more recent knowledge also suggests obesity to be associated with reduced morbidity and mortality - the “obesity paradox”. This ...
    • Mice depleted for Exchange Proteins Directly Activated by cAMP (Epac) exhibit irregular liver regeneration in response to partial hepatectomy 

      Åsrud, Kathrine Sivertsen; Pedersen, Line; Æsøy, Reidun; Muwonge, Haruna; Aasebø, Elise; Pettersen, Ina Katrine Nitschke; Herfindal, Lars; Dobie, Ross; Jenkins, Stephen; Berge, Rolf Kristian; Henderson, Neil Cowan; Selheim, Frode; Doskeland, Stein Ove; Bakke, Marit (Peer reviewed; Journal article, 2019-09-24)
      The exchange proteins directly activated by cAMP 1 and 2 (Epac1 and Epac2) are expressed in a cell specific manner in the liver, but their biological functions in this tissue are poorly understood. The current study was ...
    • Regulation of CDKN2B expression by interaction of Arnt with Miz-1 - a basis for functional integration between the HIF and Myc gene regulatory pathways 

      Æsøy, Reidun; Gradin, Katarina; Åsrud, Kathrine Sivertsen; Høivik, Erling Andre; Ruas, Jorge L.; Poellinger, Lorenz; Bakke, Marit (Peer reviewed; Journal article, 2014-03-11)
      Background: Hypoxia- and Myc-dependent transcriptional regulatory pathways are frequently deregulated in cancer cells. These pathways converge in many cellular responses, but the underlying molecular mechanisms are unclear. ...
