• Basal level of autophagy and MAP1LC3B-II as potential biomarkers for DHA-induced cytotoxicity in colorectal cancer cells 

      Samdal, Helle; Sandmoe, Malin Alise; Olsen, Lene Christin; Jarallah, Elaf Ali Hadi; Høiem, Therese Stork; Schønberg, Svanhild Margrethe Arentz; Pettersen, Caroline Hild (Journal article, 2018)
      The omega‐3 fatty acid docosahexaenoic acid (DHA) is known as an anticancer agent. Colorectal cancer (CRC) cells exhibit different sensitivity toward DHA, but the mechanisms involved are still unclear. Gene expression ...
    • Establishment of a patient-derived xenograft model of colorectal cancer in CIEA NOG mice and exploring smartfish liquid diet as a source of omega-3 fatty acids 

      Samdal, Helle; Olsen, Lene Christin; Grøn, Knut Sverre; Røyset, Elin Synnøve; Høiem, Therese Stork; Nervik, Ingunn; Sætrom, Pål; Wibe, Arne; Schønberg, Svanhild Margrethe Arentz; Pettersen, Caroline Hild (Peer reviewed; Journal article, 2021)
      Cancer patient-derived xenografts (PDXs) better preserve tumor characteristics and microenvironment than traditional cancer cell line derived xenografts and are becoming a valuable model in translational cancer research ...
    • An optimized MALDI MSI protocol for spatial detection of tryptic peptides in fresh frozen prostate tissue 

      Høiem, Therese Stork; Andersen, Maria Karoline; Martin-Lorenzo, Marta; Longuespée, Rémi; Claes, Britt S.R.; Nordborg, Anna; Dewez, Frédéric; Balluff, Benjamin; Giampà , Marco; Sharma, Animesh; Hagen, Lars; Heeren, Ron M.A.; Bathen, Tone Frost; Giskeødegård, Guro F.; Krossa, Sebastian; Tessem, May-Britt (Peer reviewed; Journal article, 2022)
      MALDI MS imaging (MSI) is a powerful analytical tool for spatial peptide detection in heterogeneous tissues. Proper sample preparation is crucial to achieve high quality, reproducible measurements. Here we developed an ...
    • Prediction of recurrence from metabolites and expression of TOP2A and EZH2 in prostate cancer patients treated with radiotherapy 

      Hansen, Ailin Falkmo; Høiem, Therese Stork; Selnæs, Kirsten Margrete; Bofin, Anna M.; Størkersen, Øystein; Bertilsson, Helena; Wright, Alan J.; Giskeødegård, Guro F.; Bathen, Tone Frost; Rye, Morten Beck; Tessem, May-Britt (Peer reviewed; Journal article, 2023)
      Background The dual upregulation of TOP2A and EZH2 gene expression has been proposed as a biomarker for recurrence in prostate cancer patients to be treated with radical prostatectomy. A low tissue level of the metabolite ...
    • 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; Peer reviewed, 2020)
      Levels of zinc, along with its mechanistically related metabolites citrateand aspartate, are widely reported as reduced in prostate cancer compared to healthytissue and are therefore pointed out as potential cancer biomarkers. ...
    • 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 (Peer reviewed; Journal article, 2021)
      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 ...
