    • Clinical Efficacy and Safety of Bevacizumab Monotherapy in Patients with Metastatic Melanoma: Predictive Importance of Induced Early Hypertension 

      Schuster, Cornelia; Eikesdal, Hans Petter; Puntervoll, Hanne; Geisler, Jürgen; Geisler, Stephanie; Molven, Anders; Akslen, Lars A. (Peer reviewed; Journal article, 2012-06-15)
      Background: VEGF driven angiogenesis plays a key role in cancer progression. We determined the clinical efficacy of bevacizumab monotherapy in patients with metastatic melanoma. Methods and Findings: Thirty-five patients ...

    • Clonal evolution in primary breast cancers under sequential epirubicin and docetaxel monotherapy 

      Venizelos, Andreas; Engebrethsen, Christina; Deng, Wei; Geisler, Jürgen; Geisler, Stephanie; Iversen, Gjertrud Titlestad; Aas, Turid; Aase, Hildegunn Siv; Seyedzadeh, Manouchehr; Steinskog, Eli Sihn Samdal; Myklebost, Ola; Nakken, Sigve; Vodák, Daniel; Hovig, Eivind; Meza, Leonardo Zepeda; Lønning, Per Eystein; Knappskog, Stian; Eikesdal, Hans Petter (Journal article; Peer reviewed, 2022)
      Background Subclonal evolution during primary breast cancer treatment is largely unexplored. We aimed to assess the dynamic changes in subclonal composition of treatment-naïve breast cancers during neoadjuvant ...

    • Concomitant inactivation of the p53- and pRB- functional pathways predicts resistance to DNA damaging drugs in breast cancer in vivo 

      Knappskog, Stian; Berge, Elisabet Ognedal; Chrisanthar, Ranjan; Geisler, Stephanie; Staalesen, Vidar; Leirvaag, Beryl; Yndestad, Synnøve; de Faveri, Elise Norheim; Karlsen, Bård Ove; Wedge, David C.; Akslen, Lars A.; Lilleng, Peer Kåre; Løkkevik, Erik; Lundgren, Steinar; Østenstad, Bjørn; Risberg, Terje; Mjaaland, Ingvil; Aas, Turid; Lønning, Per Eystein (Peer reviewed; Journal article, 2015-10)
      Chemoresistance is the main obstacle to cancer cure. Contrasting studies focusing on single gene mutations, we hypothesize chemoresistance to be due to inactivation of key pathways affecting cellular mechanisms such as ...

    • DNA methylation profiling in doxorubicin treated primary locally advanced breast tumours identifies novel genes associated with survival and treatment response 

      Dejeux, Emelyne; Rønneberg, Jo A.; Solvang, Hiroko Kato; Bukholm, Ida Rashida Khan; Geisler, Stephanie; Aas, Turid; Gut, Ivo G.; Børresen-Dale, Anne-Lise; Lønning, Per Eystein; Kristensen, Vessela N.; Tost, Jörg (Peer reviewed; Journal article, 2010-03-25)
      Background: Breast cancer is the most frequent cancer in women and consists of a heterogeneous collection of diseases with distinct histopathological, genetic and epigenetic characteristics. In this study, we aimed to ...

    • Expression of full-length p53 and its isoform Δp53 in breast carcinomas in relation to mutation status and clinical parameters 

      Baumbusch, Lars O.; Myhre, Simen; Langerød, Anita; Bergamaschi, Anna; Geisler, Stephanie; Lønning, Per Eystein; Deppert, Wolfgang; Dornreiter, Irene; Børresen-Dale, Anne-Lise (Molecular Cancer 5(47), Peer reviewed; Journal article, 2006-10-20)
      Background: The tumor suppressor gene p53 (TP53) controls numerous signaling pathways and is frequently mutated in human cancers. Novel p53 isoforms suggest alternative splicing as a regulatory feature of p53 activity. ...

    • Identification and characterization of retinoblastoma gene mutations disturbing apoptosis in human breast cancers 

      Berge, Elisabet Ognedal; Knappskog, Stian; Geisler, Stephanie; Staalesen, Vidar; Pacal, Marec; Børresen-Dale, Anne-Lise; Puntervoll, Pål; Lillehaug, Johan; Lønning, Per Eystein (Peer reviewed; Journal article, 2010-07-01)
      Background The tumor suppressor pRb plays a key role regulating cell cycle arrest, and disturbances in the RB1 gene have been reported in different cancer forms. However, the literature reports contradictory findings with ...

    • Prenatal BRCA1 epimutations contribute significantly to triple-negative breast cancer development 

      Nikolaienko, Oleksii; Eikesdal, Hans Petter; Berge, Elisabet Ognedal; Gilje, Bjørnar; Lundgren, Steinar; Blix, Egil Støre; Espelid, Helge; Geisler, Jürgen; Geisler, Stephanie; Janssen, Emiel; Yndestad, Synnøve; Minsaas, Laura; Leirvaag, Beryl; Lillestøl, Reidun Kristine; Knappskog, Stian; Lønning, Per Eystein (Journal article; Peer reviewed, 2023)
      Background Normal cell BRCA1 epimutations have been associated with increased risk of triple-negative breast cancer (TNBC). However, the fraction of TNBCs that may have BRCA1 epimutations as their underlying cause is ...
