      Purpose - The primary aim was to evaluate whether anti-3-[<sup>18</sup>F]FACBC PET combined with conventional MRI correlated better with histomolecular diagnosis (reference standard) than MRI alone in glioma diagnostics. The ability of anti-3-[<sup>18</sup>F]FACBC to differentiate between molecular and histopathological entities in gliomas was also evaluated.<p> <p>Methods - In this prospective ...
    • Integrative metabolic and transcriptomic profiling of prostate cancer tissue containing reactive stroma 

      Andersen, Maria Karoline; Rise, Kjersti; Giskeødegård, Guro F.; Richardsen, Elin; Bertilsson, Helena; Størkersen, Øystein; Bathen, Tone Frost; Rye, Morten Beck; Tessem, May-Britt (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-24)
      Reactive stroma is a tissue feature commonly observed in the tumor microenvironment of prostate cancer and has previously been associated with more aggressive tumors. The aim of this study was to detect differentially expressed genes and metabolites according to reactive stroma content measured on the exact same prostate cancer tissue sample. Reactive stroma was evaluated using histopathology from ...
    • Metabolite and lipoprotein responses and prediction of weight gain during breast cancer treatment 

      Madssen, Torfinn Støve; Thune, Inger; Flote, Vidar Gordon; Lundgren, Steinar; Bertheussen, Gro Falkener; Frydenberg, Hanne; Wist, Erik; Schlichting, Ellen; Schäfer, Hartmut; Fjøsne, Hans Erikssønn; Vettukattil, Muhammad Riyas; Lømo, Jon; Bathen, Tone Frost; Giskeødegård, Guro F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-07)
      <p><i>Background</i>: Breast cancer treatment has metabolic side effects, potentially affecting risk of cardiovascular disease (CVD) and recurrence. We aimed to compare alterations in serum metabolites and lipoproteins during treatment between recipients and non-recipients of chemotherapy, and describe metabolite profiles associated with treatment-related weight gain.</p> <p><i>Methods</i>: This ...
    • Serum levels of inflammation-related markers and metabolites predict response to neoadjuvant chemotherapy with and without bevacizumab in breast cancers 

      Nome, Marianne Eikhom; Euceda, Leslie R.; Jabeen, Shakila; Debik, Julia; Bathen, Tone Frost; Giskeødegård, Guro F.; Tasken, Kristin Austlid; Mælandsmo, Gunhild Mari; Halvorsen, Bente; Yndestad, Arne; Borgen, Elin; Garred, Øystein; Aukrust, Pål; Ueland, Thor; Engebraaten, Olav; Kristensen, Vessela N.; Tekpli, Xavier (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-24)
      Angiogenesis is necessary for tumor growth and has been targeted in breast cancer; however, it is unclear which patients will respond and benefit from antiangiogenic therapy. We report noninvasive monitoring of patient response to neoadjuvant chemotherapy given alone or in combination with anti‐vascular endothelial growth factor (bevacizumab) in a randomized clinical trial. At four time points during ...
    • Simultaneous Detection of Zinc and Its Pathway Metabolites Using MALDI MS Imaging of Prostate Tissue 

      Andersen, Maria Karoline; Krossa, Sebastian; Høiem, Therese Stork; Buchholz, Rebecca; Claes, Britt S.R.; Balluff, Benjamin; Ellis, Shane; Richardsen, Elin; Bertilsson, Helena; Heeren, Ron M.A.; Bathen, Tone Frost; Karst, Uwe; Giskeødegård, Guro F.; Tessem, May-Britt (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-16)
      Levels of zinc, along with its mechanistically related metabolites citrate and aspartate, are widely reported as reduced in prostate cancer compared to healthy tissue and are therefore pointed out as potential cancer biomarkers. Previously, it has only been possible to analyze zinc and metabolites by separate detection methods. Through matrix-assisted laser desorption/ionization mass spectrometry ...
    • Spatial differentiation of metabolism in prostate cancer tissue by MALDI-TOF MSI 

      Andersen, Maria Karoline; Høiem, Therese Stork; Claes, Britt S.R.; Balluff, Benjamin; Marta, Martin-Lorenzo; Richardsen, Elin; Krossa, Sebastian; Bertilsson, Helena; Heeren, Ron M.A.; Rye, Morten Beck; Giskeødegård, Guro F.; Bathen, Tone Frost; Tessem, May-Britt (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-29)
      Background - Prostate cancer tissues are inherently heterogeneous, which presents a challenge for metabolic profiling using traditional bulk analysis methods that produce an averaged profile. The aim of this study was therefore to spatially detect metabolites and lipids on prostate tissue sections by using mass spectrometry imaging (MSI), a method that facilitates molecular imaging of heterogeneous ...
