  • Fack, Fred; Espedal, Heidi; Keunen, Olivier; Golebiewska, Anna; Obad, Nina; Harter, Patrick N.; Mittelbronn, Michel; Bähr, Oliver; Weyerbrock, Astrid; Stuhr, Linda Elin Birkhaug; Miletic, Hrvoje; Sakariassen, Per Øystein; Stieber, Daniel; Rygh, Cecilie Brekke; Lund-Johansen, Morten; Zheng, Liang; Gottlieb, Eyal; Niclou, Simone P.; Bjerkvig, Rolf (Journal article, Springer, 2015-01)
    Anti-angiogenic therapy in glioblastoma (GBM) has unfortunately not led to the anticipated improvement in patient prognosis. We here describe how human GBM adapts to bevacizumab treatment at the metabolic level. By performing ...
  • Sakariassen, Per Øystein; Immervoll, Heike; Chekenya, Martha (Journal article, Elsevier, 2007-11)
    Malignant primary brain tumors are characterized by a short median survival and an almost 100% tumorrelated mortality. Despite the addition of new chemotherapy regimes, the overall survival has improved marginally, and ...
  • Yang, Ning; Yan, Tao; Zhu, Huaiyang; Liang, Xiao; Leiss, Lina; Sakariassen, Per Øystein; Skaftnesmo, Kai Ove; Huang, Bin; Costea, Daniela Elena; Enger, Per Øyvind; Li, Xingang; Wang, Jian (Journal article, BioMed Central, 2014-10-04)
    Background: Although several studies suggest that stromal fibroblasts mediate treatment resistance in several cancer types, little is known about how tumor-associated astrocytes modulate the treatment response in brain ...
  • Svendsen, Agnete; Verhoeff, Joost J. C.; Immervoll, Heike; Brøgger, Jan C.; Kmiecik, Justyna; Poli, Aurélie; Netland, Inger A.; Planagumà, Jesús; Torsvik, Anja; Sakariassen, Per Øystein; Bjerkvig, Rolf; Enger, Per Øyvind; Tronstad, Karl Johan (Peer reviewed; Journal article, Springer, 2011-08-24)
    Glioblastoma (GBM) is a highly aggressive brain tumour, where patients respond poorly to radiotherapy and exhibit dismal survival outcomes. The mechanisms of radioresistance are not completely understood. However, cancer ...
  • Immervoll, Heike; Hoem, Dag; Sakariassen, Per Øystein; Steffensen, Ole Johnny; Molven, Anders (Journal article; Peer reviewed, BioMed Central, 2008-02-08)
    Background It has been suggested that a small population of cells with unique self-renewal properties and malignant potential exists in solid tumors. Such "cancer stem cells" have been isolated by flow cytometry, followed ...
  • Moen, Ingrid; Øyan, Anne Margrete; Kalland, Karl-Henning; Tronstad, Karl Johan; Akslen, Lars A.; Chekenya, Martha; Sakariassen, Per Øystein; Reed, Rolf K.; Stuhr, Linda Elin Birkhaug (Journal article; Peer reviewed, Public Library of Science, 2009-07-28)
    Tumor hypoxia is relevant for tumor growth, metabolism and epithelial-to-mesenchymal transition (EMT). We report that hyperbaric oxygen (HBO) treatment induced mesenchymal-to-epithelial transition (MET) in a dimetyl-a-b ...
  • Wang, Jian; Miletic, Hrvoje; Sakariassen, Per Øystein; Huszthy, Peter Csaba; Jacobsen, Hege; Brekkå, Narve; Li, Xingang; Zhao, Peng; Mørk, Sverre; Chekenya, Martha; Bjerkvig, Rolf; Enger, Per Øyvind (Journal article, BioMed Central, 2009-12-29)
    Background: Establishing clinically relevant animal models of glioblastoma multiforme (GBM) remains a challenge, and many commonly used cell line-based models do not recapitulate the invasive growth patterns of patient ...
