    • Conditional expression of retrovirally delivered anti-MYCN shRNA as an in vitro model system to study neuronal differentiation in MYCN-amplified neuroblastoma 

      Henriksen, Jørn Remi; Haug, Bjørn Helge; Büchner, Jochen; Tømte, Ellen; LØkke, cecilie; Flaegstad, Trond; Einvik, christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Background: Neuroblastoma is a childhood cancer derived from immature cells of the sympathetic nervous system. The disease is clinically heterogeneous, ranging from neuronal differentiated benign ganglioneuromas to aggressive metastatic tumours with poor prognosis. Amplification of the MYCN oncogene is a well established poor prognostic factor found in up to 40% of high risk neuroblastomas. Using ...

    • Tumour-suppressor microRNAs let-7 and mir-101 target the proto-oncogene MYCN and inhibit cell proliferation in MYCN-amplified neuroblastoma 

      Buechner, Jochen; Tømte, Ellen; Haug, Bjørn Helge; Henriksen, Jørn Remi; Løkke, Cecilie; Flægstad, Trond; Einvik, Christer (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-06-07)
      BACKGROUND: MicroRNAs (miRNAs) regulate expression of many cancer-related genes through posttranscriptional repression of their mRNAs. In this study we investigate the proto-oncogene MYCN as a target for miRNA regulation.<p> <p>METHODS: A luciferase reporter assay was used to investigate software-predicted miRNA target sites in the 30 -untranslated region (30 UTR) of MYCN. The miRNAs were ...
