    • Basal‐like breast cancer engages tumor‐supportive macrophages via secreted factors induced by extracellular S100A4 

      Prasmickaite, Lina; Tenstad, Ellen; Pettersen, Solveig; Jabeen, Shakila; Egeland, Eivind Valen; Nord, Silje; Pandya, Abhilash D.; Haugen, Mads Haugland; Kristensen, Vessela N.; Børresen-Dale, Anne-Lise; Engebråten, Olav; Mælandsmo, Gunhild Mari (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-09)
      The tumor microenvironment (TME) may influence both cancer progression and therapeutic response. In breast cancer, particularly in the aggressive triple‐negative/basal‐like subgroup, patient outcome is strongly associated with the tumor's inflammatory profile. Tumor‐associated macrophages (TAMs) are among the most abundant immune cells in the TME, shown to be linked to poor prognosis and therapeutic ...

    • 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 ...

    • 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 ...

    • Stroma-induced phenotypic plasticity offers phenotype-specific targeting to improve melanoma treatment 

      Seip, Kotryna; Jørgensen, Kjetil Nordbø; Haselager, Marco Vincent; Albrecht, Marco; Haugen, Mads Haugland; Egeland, Eivind Valen; Lucarelli, Philippe; Engebråten, Olav; Sauter, Thomas; Mælandsmo, Gunhild Mari; Prasmickaite, Lina (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-18)
      Cancer cells' phenotypic plasticity, promoted by stromal cells, contributes to intra-tumoral heterogeneity and affects response to therapy. We have disclosed an association between fibroblast-stimulated phenotype switching and resistance to the clinically used BRAF inhibitor (BRAFi) vemurafenib in malignant melanoma, revealing a challenge in targeting the fibroblast-induced phenotype. Here we compared ...
