Enhancement of iodinin solubility by encapsulation into cyclodextrin nanoparticles
Prandina, Anthony; Herfindal, Lars; Radix, S; Rongved, Pål; Doskeland, Stein Ove; Le Borgne, Marc; Perret, F (Journal article; Peer reviewed, 2018)Phenazine is known to regroup planar nitrogen-containing heterocyclic compounds. It was used here to enhance the bioavailability of the biologically important compound iodinin, which is near insoluble in aqueous solutions. ... -
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 ... -
Mathematical modelling of nitric oxide/cyclic GMP/cyclic AMP signalling in platelets
Kleppe, Rune; Jonassen, Inge; Doskeland, Stein Ove; Selheim, Frode (Peer reviewed; Journal article, 2018-02-19)Platelet activation contributes to normal haemostasis but also to pathologic conditions like stroke and cardiac infarction. Signalling by cGMP and cAMP inhibit platelet activation and are therefore attractive targets for ... -
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 ... -
New prodrugs and analogs of the phenazine 5,10-dioxide natural products iodinin and myxin promote selective cytotoxicity towards human acute myeloid leukemia cells
Viktorsson, Elvar Örn; Aesoy, Reidun; Støa, Sindre; Lekve, Viola; Doskeland, Stein Ove; Herfindal, Lars; Rongved, Pål (Journal article, 2021)Novel chemotherapeutic strategies for acute myeloid leukemia (AML) treatment are called for. We have recently demonstrated that the phenazine 5,10-dioxide natural products iodinin (3) and myxin (4) exhibit potent and ... -
The progression of acute myeloid leukemia from first diagnosis to chemoresistant relapse: A comparison of proteomic and phosphoproteomic profiles
Aasebø, Elise; Berven, Frode; Hovland, Randi; Doskeland, Stein Ove; Bruserud, Øystein; Selheim, Frode; Hernandez-Valladares, Maria (Journal article; Peer reviewed, 2020)Acute myeloid leukemia (AML) is an aggressive hematological malignancy. Nearly 50% of the patients who receive the most intensive treatment develop chemoresistant leukemia relapse. Although the leukemogenic events leading ...
