    • 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 ...

    • 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 ...

    • Metabolic reprogramming supports the invasive phenotype in malignant melanoma 

      Bettum, Ingrid Johanne; Gorad, Saurabh Sayajirao; Barkovskaya, Anna; Pettersen, Solveig; Moestue, Siver Andreas; Vasiliauskaite, Kotryna; Tenstad, Ellen; Øyjord, Tove Ragnhild; Risa, Øystein; Nygaard, Vigdis; Mælandsmo, Gunhild; Prasmickaite, Lina (Journal article; Tidsskriftartikkel, 2015)
      Invasiveness is a hallmark of aggressive cancer like malignant melanoma, and factors involved in acquisition or maintenance of an invasive phenotype are attractive targets for therapy. We investigated melanoma phenotype modulation induced by the metastasis-promoting microenvironmental protein S100A4, focusing on the relationship between enhanced cellular motility, dedifferentiation and metabolic ...
