Bone morphogenetic protein-9 suppresses growth of myeloma cells by signaling through ALK2 but is inhibited by endoglin
Olsen, Oddrun Elise; Wader, Karin Fahl; Misund, Kristine; Våtsveen, Thea Kristin; Rø, Torstein Baade; Mylin, Anne K.; Turesson, I; Størdal, Berit Fladvad; Moen, Siv Helen; Standal, Therese; Waage, Anders; Sundan, Anders; Holien, Toril (Journal article; Peer reviewed, 2014)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 ... -
Caspase-8 regulates the expression of pro- and anti-inflammatory cytokines in human bone marrow-derived mesenchymal stromal cells
Moen, Siv Helen; Westhrin, Marita; Zahoor, Muhammad; Nikolai N., Nørgaard; Hella, Hanne; Størdal, Berit Fladvad; Sundan, Anders; Nilsen, Nadra J.; Sponaas, Anne-Marit; Standal, Therese (Journal article; Peer reviewed, 2016)Introduction: Mesenchymal stem cells, also called mesenchymal stromal cells, MSCs, have great potential in stem cell therapy partly due to their immunosuppressive properties. How these cells respond to chronic inflammatory ... -
Chemerin is elevated in multiple myeloma patients and is expressed by stromal cells and pre-adipocytes
Westhrin, Marita; Moen, Siv Helen; Kristensen, Ida Bruun; Buene, Glenn; Mylin, Anne Kærsgaard; Turesson, Ingemar; Abildgaard, Niels; Waage, Anders; Standal, Therese (Journal article; Peer reviewed, 2018)Chemerin is a recently discovered adipokine shown to be involved in both inflammatory and metabolic processes. Here, we demonstrate that chemerin serum levels are elevated in patients with multiple myeloma and that it ... -
Human Toll-like Receptor 8 (TLR8) Is an Important Sensor of Pyogenic Bacteria, and Is Attenuated by Cell Surface TLR Signaling
Moen, Siv Helen; Ehrnström, Birgitta; Kojen, June Frengen; Yurchenko, Mariya; Beckwith, Kai Sandvold; Afset, Jan Egil; Damås, Jan Kristian; Zhenyi, Hu; Hang, Yin; Espevik, Terje; Stenvik, Jørgen (Journal article; Peer reviewed, 2019)TLR8 is an endosomal sensor of RNA degradation products in human phagocytes, and is involved in the recognition of viral and bacterial pathogens. We previously showed that in human primary monocytes and monocyte derived ... -
Hypoxia promotes IL-32 expression in myeloma cells, and high expression is associated with poor survival and bone loss
Zahoor, Muhammad; Westhrin, Marita; Aass, Kristin Roseth; Moen, Siv Helen; Misund, Kristine; Psonka-Antonczyk, Katarzyna Maria; Giliberto, Mariaserena; Buene, Glenn; Sundan, Anders; Waage, Anders; Sponaas, Anne-Marit; Standal, Therese (Journal article; Peer reviewed, 2017)Multiple myeloma (MM) is a hematologic cancer characterized by expansion of malignant plasma cells in the bone marrow. Most patients develop an osteolytic bone disease, largely caused by increased osteoclastogenesis. The ... -
IL-32 and multiple myeloma bone disease
Aass, Kristin Roseth (Master thesis, 2016)Multiple myeloma is a malignancy of plasma cells characterized by multiple tumors in the bone marrow and progressive osteolytic bone disease. The bone lesions are caused by increased bone resorption by osteoclasts and ... -
Influence of Inflammation and Cancer on Mesenchymal Stem Cell Function
Moen, Siv Helen (Doktoravhandlinger ved NTNU, 1503-8181; 2014:46, Doctoral thesis, 2014) -
The proportion of CD16+CD14dim monocytes increases with tumor cell load in bone marrow of patients with multiple myeloma
Sponaas, Anne-Marit; Moen, Siv Helen; Liabakk, Nina-Beate; Feyzi, Emadoldin; Holien, Toril; Kvam, Solveig; Grøseth, Lill Anny Gunnes; Størdal, Berit Fladvad; Buene, Glenn; Espevik, Terje; Waage, Anders; Standal, Therese; Sundan, Anders (Journal article; Peer reviewed, 2015)Multiple myeloma is an incurable cancer with expansion of malignant plasma cells in the bone marrow. Previous studies have shown that monocytes and macrophages in the bone marrow milieu are important for tumor growth ... -
TLR8 and complement C5 induce cytokine release and thrombin activation in human whole blood challenged with Gram-positive bacteria
Ehrnstrøm, Birgitta; Kojen, June Frengen; Giambelluca, Miriam; Ryan, Liv; Moen, Siv Helen; Hu, Zhenyi; Yin, Hang; Mollnes, Tom Eirik; Damås, Jan Kristian; Espevik, Terje; Stenvik, Jørgen (Journal article; Peer reviewed, 2020)We recently showed that TLR8 is critical for the detection of Gram‐positive bacteria by human monocytes. Here, we hypothesized that TLR8 and complement together regulate antibacterial responses in human blood. Anticoagulated ... -
Toll-Like Receptor 8 Is a Major Sensor of Group B Streptococcus But Not Escherichia coli in Human Primary Monocytes and Macrophages
Ehrnstrøm, Birgitta; Beckwith, Kai Sandvold; Yurchenko, Mariya; Moen, Siv Helen; Frengen Kojen, June; Lentini, Germana; Teti, G.; Damås, Jan Kristian; Espevik, Terje; Stenvik, Jørgen (Journal article; Peer reviewed, 2017)TLR8 is the major endosomal sensor of degraded RNA in human monocytes and macrophages. It has been implicated in the sensing of viruses and more recently also bacteria. We previously identified a TLR8-IFN regulatory factor ... -
Toll-like receptor-mediated regulation of IL-32 in multiple myeloma cells
Tryggestad, Synne Stokke (Master thesis, 2020)Myelomatose, eller beinmargskreft, skyldes ukontrollert vekst av maligne plasmaceller i beinmargen. Pasienter med myelomatose er spesielt utsatt for infeksjoner, som også er en utbredt dødsårsak hos disse pasientene. ...
