    • High expression of miR-17-5p in tumor epithelium is a predictor for poor prognosis for prostate cancer patients 

      Støen, Maria Jenvin; Andersen, Sigve; Rakaee, Mehrdad; Pedersen, Mona Irene; Ingebriktsen, Lise Martine; Bremnes, Roy M.; Dønnem, Tom; Lombardi, Ana Paola; Kilvær, Thomas Karsten; Rasmussen Busund, Lill-Tove; Richardsen, Elin (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-05)
      MicroRNAs (miRs) are small non-coding RNA molecules, which are involved in the development of various malignancies, including prostate cancer (PCa). miR-17-5p is considered the most prominent member of the miR-17-92 cluster, with an essential regulatory function of fundamental cellular processes. In many malignancies, up-regulation of miR-17-5p is associated with worse outcome. In PCa, miR-17-5p has ...

    • Highly oxidized albumin is cleared by liver sinusoidal endothelial cells via the receptors stabilin-1 and -2 

      Holte, Christopher Florian; Szafranska, Karolina Joanna; Kruse, Larissa Dorothea; Simon-Santamaria, Jaione; Li, Ruomei; Svistounov, Dmitri; McCourt, Peter Anthony (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-05)
      Oxidized albumin (oxHSA) is elevated in several pathological conditions, such as decompensated cirrhosis, acute on chronic liver failure and liver mediated renal failure. Patient derived oxidized albumin was previously shown to be an infammatory mediator, and in normal serum levels of oxHSA are low. The removal from circulation of oxidized albumins is therefore likely required for maintenance of ...

    • A highly selective purine-based inhibitor of CSF1R potently inhibits osteoclast differentiation 

      Aarhus, Thomas Ihle; Eickhoff, Jan; Klebl, Bert; Unger, Anke; Boros, Johanna; Choidas, Axel; Zischinsky, Mia-Lisa; Wolowczyk, Camilla Izabel; Bjørkøy, Geir; Sundby, Eirik; Hoff, Bård Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-28)
      The colony-stimulating factor 1 receptor (CSF1R) plays an important role in the regulation of many inflammatory processes, and overexpression of the kinase is implicated in several disease states. Identifying selective, smallmolecule inhibitors of CSF1R may be a crucial step toward treating these disorders. Through modelling, synthesis, and a systematic structure-activity relationship study, we ...
