    • 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 ...

    • Wnt/β-catenin pathway regulates MGMT gene expression in cancer and inhibition of Wnt signalling prevents chemoresistance 

      Wickström, Malin; Dyberg, Cecilia; Milosevic, Jelena; Einvik, Christer; Calero, Raul; Sveinbjørnsson, Baldur; Sandén, Emma; Darabi, Anna; Siesjö, Peter; Kool, Marcel; Kogner, Per; Baryawno, Ninib; Johnsen, John Inge (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-25)
      The DNA repair enzyme O6-methylguanine-DNA methyltransferase (MGMT) is commonly overexpressed in cancers and is implicated in the development of chemoresistance. The use of drugs inhibiting MGMT has been hindered by their haematologic toxicity and inefficiency. As a different strategy to inhibit MGMT we investigated cellular regulators of MGMT expression in multiple cancers. Here we show a ...
