• Altered metabolic landscape in IDH‐mutant gliomas affects phospholipid, energy, and oxidative stress pathways 

      Fack, Fred; Tardito, Saverio; Hochart, Guillaume; Oudin, Anaïs; Zheng, Liang; Fritah, Sabrina; Golebiewska, Anna; Nazarov, Petr; Bernard, Amandine; Hau, Ann-Christin; Keunen, Olivier; Leenders, William P.J.; Lund-Johansen, Morten; Stauber, Jonathan; Gottlieb, Eyal; Bjerkvig, Rolf; Niclou, Simone Pierrette (Peer reviewed; Journal article, 2017)
      Heterozygous mutations in NADP‐dependent isocitrate dehydrogenases (IDH) define the large majority of diffuse gliomas and are associated with hypermethylation of DNA and chromatin. The metabolic dysregulations imposed by ...
    • Bevacizumab treatment induces metabolic adaptation toward anaerobic metabolism in glioblastomas 

      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 (Peer reviewed; Journal article, 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 ...
    • Lack of functional normalisation of tumour vessels following anti-angiogenic therapy in glioblastoma 

      Obad, Nina; Espedal, Heidi; Jirík, Radovan; Sakariassen, Per Øystein; Rygh, Cecilie Brekke; Lund-Johansen, Morten; Taxt, Torfinn; Niclou, Simone Pierrette; Bjerkvig, Rolf; Keunen, Olivier (Peer reviewed; Journal article, 2017)
      Neo-angiogenesis represents an important factor for the delivery of oxygen and nutrients to a growing tumour, and is considered to be one of the main pathodiagnostic features of glioblastomas (GBM). Anti-angiogenic therapy ...
    • Multimodal imaging of gliomas in the context of evolving cellular and molecular therapies 

      Keunen, Olivier; Taxt, Torfinn; Grüner, Renate; Lund-Johansen, Morten; Tonn, Joerg-Christian; Pavlin, Tina; Bjerkvig, Rolf; Niclou, Simone P.; Thorsen, Frits Alan (Peer reviewed; Journal article, 2014-09-30)
      The vastmajority ofmalignant gliomas relapse after surgery and standard radio-chemotherapy. Novelmolecular and cellular therapies are thus being developed, targeting specific aspects of tumor growth.While histopathology ...
    • Multimodal Imaging of Physiologic Changes Induced by Anti-Angiogenic Therapy in Glioblastoma 

      Keunen, Olivier (Doctoral thesis, 2014-12-18)
      Glioblastoma (GBM) is the most frequent and malignant form of primary brain tumors. The standard of care for this disease consists in surgical resection, followed by radiotherapy and chemotherapy. Yet, the infiltrative ...
