    • MYCN-regulated miRNAs Inhibit Secretion of the Tumor Suppressor DICKKOPF-3 (DKK3) in Neuroblastoma 

      Haug, Bjørn Helge; Henriksen, Jørn Remi; Buechner, Jochen; Kogner, Per; Martinsson, Tommy; Flægstad, Trond; Sveinbjørnsson, Baldur; Einvik, Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      The MYCN oncogene is frequently amplified in neuroblastoma. It is one of the most consistent markers of a bad prognosis for this disease. Dickkopf-3 (DKK3) is a secreted protein of the Dickkopf family of Wnt regulators. It functions as a tumor suppressor in a range of cancers, including neuroblastoma. MYCN was recently found to downregulate DKK3 mRNA. In this study, we show that MYCN knockdown in ...

    • Rho-associated kinase is a therapeutic target in neuroblastoma 

      Dyberg, Cecilia; Fransson, Susanne; Andonova, Teodora; Sveinbjørnsson, Baldur; Lannerholm-Palm, Jessika; Olsen, Thale Kristin; Forsberg, David; Herlenius, Eric; Martinsson, Tommy; Brodin, Bertha; Kogner, Per; Johnsen, John Inge; Wickström, Malin (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-24)
      Neuroblastoma is a peripheral neural system tumor that originates from the neural crest and is the most common and deadly tumor of infancy. Here we show that neuroblastoma harbors frequent mutations of genes controlling the Rac/Rho signaling cascade important for proper migration and differentiation of neural crest cells during neuritogenesis. RhoA is activated in tumors from neuroblastoma ...
