      Multiple myeloma is a malignancy of plasma cells predominantly located in the bone marrow. A number of bone morphogenetic proteins (BMPs) induce apoptosis in myeloma cells in vitro, and with this study we add BMP-9 to the ...
    • FKBP12 is a major regulator of ALK2 activity in multiple myeloma cells 

      Quist-Løkken, Ingrid; Andersson-Rusch, Clara Leticia; Kastnes, Martin Haugrud; Jürgen Markus Kolos, , Jürgen Markus; Jatzlau, Jerome; Hella, Hanne; Olsen, Oddrun Elise; Sundan, Anders; Knaus, Petra; Hausch, Felix; Holien, Toril (Journal article; Peer reviewed, 2023)
      Background: The immunophilin FKBP12 binds to TGF-β family type I receptors, including the BMP type I receptor ALK2. FKBP12 keeps the type I receptor in an inactive state and controls signaling activity. Removal of FKBP12 ...
    • GDF-15 signalling in multiple myeloma 

      Skjærvik, Anette (Master thesis, 2015)
      Abstract Multiple myeloma (MM), also known as bone marrow cancer, is a malignancy of hypermutated antibody-producing plasma cells in the bone marrow. An accumulation of this antibody (M-protein) can be detected in blood- ...
    • High concentrations of soluble endoglin can inhibit BMP9 signaling in non-endothelial cells 

      Andersson-Rusch, Clara Leticia; Liu, Bin; Quist-Løkken, Ingrid; Upton, Paul D.; Olsen, Oddrun Elise; Hella, Hanne; Yang, Xudong; Tong, Zhen; Morrell, Nicholas W.; Holien, Toril; Li, Wei (Peer reviewed; Journal article, 2023)
      Endoglin (ENG) is a single-pass transmembrane protein highly expressed on vascular endothelial cells, although low expression levels can be detected in many other cell types. Its extracellular domain can be found in ...
    • MYC amplifications in myeloma cell lines; correlation with MYC-inhibitor efficacy 

      Holien, Toril; Misund, Kristine; Olsen, Oddrun Elise; Baranowska, Katarzyna Anna; Buene, Glenn; Børset, Magne; Waage, Anders; Sundan, Anders (Journal article; Peer reviewed, 2015)
      In multiple myeloma, elevated MYC expression is related to disease initiation and progression. We found that in myeloma cell lines, MYC gene amplifications were common and correlated with MYC mRNA and protein. In primary ...
    • Potentiation of BMP and activin induced apoptosis in multiple myeloma cells by FK506 

      Booc, Nerissa Rae (Master thesis, 2019)
      Myelomatose er en hematologisk kreft som kjennetegnes av maligne plasmaceller som akkumuleres in benmargen. Akkumulering av myelomceller kan forårsake osteolyse mens monoklonale immunoglobuliner produsert av myelomceller ...
    • RNA-Integrity and 8-Isoprostane Levels Are Stable in Prostate Tissue Samples Upon Long-Term Storage at −80°C 

      Dybos, Sandra Amalie; Winje Brustad, Åge; Rolfseng, Toril F.Langvik; Kvam, Solveig; Olsen, Oddrun Elise; Halgunset, Jostein; Skogseth, Haakon (Peer reviewed; Journal article, 2020)
      Sampling of prostate tissue (n = 97) was performed in conjunction with planned radical prostatectomies, in collaboration with Biobank1®. The tissue used in this study was collected during the period 2003-2016, quickly ...
    • Targeting FKBP12 potentiates bone morphogenetic protein signaling in multiple myeloma cells
