    • Breast cancer patient-derived explant cultures recapitulate in vivo drug responses 

      Pettersen, Solveig; Øy, Geir Frode; Egeland, Eivind Valen; Juell, Siri; Engebråten, Olav; Mælandsmo, Gunhild Mari; Prasmickaite, Lina (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-22)
      Assessment of drug sensitivity in tumor tissue ex vivo may significantly contribute to functional diagnostics to guide personalized treatment of cancer. Tumor organoid- and explant-cultures have become attractive tools towards this goal, although culturing conditions for breast cancer (BC) tissue have been among the most challenging to develop. Validation of possibilities to detect concordant responses ...

    • Detection of disseminated tumor cells in lymph nodes from patients with early stage non-small cell lung cancer 

      Rud, Ane Kristine Kongsgaard; Pedersen, Kjetil Boye; Fodstad, Øystein; Juell, Siri; Jørgensen, Lars Hilmar; Solberg, Steinar; Helland, Åslaug; Brustugun, Odd Terje; Mælandsmo, Gunhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-17)
      Background: The regional lymph node involvement is a major prognostic factor in patients with non-small cell lung cancer (NSCLC) undergoing surgical resection. Disease relapse is common, suggesting that early disseminated disease is already present in the regional lymph nodes at the time of surgery, and that the current nodal staging classification might be suboptimal. Early detection of disseminated ...

    • Liver X receptors induce antiproliferative effects in basal-like breast cancer 

      Haugen, Mads; von der Lippe Gythfeldt, Hedda; Egeland, Eivind Valen; Svartdal Normann, Lisa; Pandya, Abhilash D.; Vedin, Lise-Lotte; Juell, Siri; Tenstad, Ellen; Øy, Geir Frode; Kristian, Alexandr; Marangoni, Elisabetta; Sørlie, Therese; Steffensen, Knut Rune; Mælandsmo, Gunhild Mari; Engebråten, Olav (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-21)
      Liver X receptors (LXRs) are nuclear transcription factors important in the regulation of cholesterol transport, and glucose and fatty acid metabolism. The antiproliferative role of LXRs has been studied in a variety of malignancies and may represent a therapeutic opportunity in cancers lacking targeted therapies, such as triple-negative breast cancer. In this study, we investigated the impact of ...

    • Novel human melanoma brain metastasis models in athymic nude fox1nu mice: Site-specific metastasis patterns reflecting their clinical origin 

      Svendsen, Henrik Aasrum; Meling, Torstein Ragnar; Nygaard, Vigdis; Waagene, Stein; Russnes, Hege Elisabeth Giercksky; Juell, Siri; Rogne, Siril Gudmundson; Pahnke, Jens; Helseth, Eirik; Fodstad, Øystein; Mælandsmo, Gunhild Mari (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-06)
      Background: Malignant melanomas frequently metastasize to the brain, but metastases in the cerebellum are underrepresented compared with metastases in the cerebrum.<p> <p>Methods: We established animal models by injecting intracardially in athymic nude fox1<sup>nu</sup> mice two human melanoma cell lines, originating from a cerebral metastasis (HM19) and a cerebellar metastasis (HM86).<p> <p>Results: ...
