    • Effect of antiangiogenic therapy on tumor growth, vasculature and kinase activity in basal- and luminal-like breast cancer xenografts 

      Lindholm, Evita Maria; Kristian, Alexandr; Nalwoga, Hawa; Kruger, Kristi; Nygård, Ståle; Akslen, Lars A.; Mælandsmo, Gunhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-03-31)
      Several clinical trials have investigated the efficacy of bevacizumab in breast cancer, and even if growth inhibiting effects have been registered when antiangiogenic treatment is given in combination with chemotherapy no gain in overall survival has been observed. One reason for the lack of overall survival benefit might be that appropriate criteria for selection of patients likely to respond ...
    • Interplay of choline metabolites and genes in patient-derived breast cancer xenografts 

      Grinde, Maria Tunset; Skrbo, Nirma; Moestue, Siver Andreas; Rødland, Einar Andreas; Borgan, Eldrid; Kristian, Alexandr; Sitter, Beathe; Bathen, Tone; Børresen-Dale, Anne-Lise; Mælandsmo, Gunhild; Sørlie, Therese; Marangoni, Elisabetta; Gribbestad, Ingrid S (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-01-21)
      Introduction: Dysregulated choline metabolism is a well-known feature of breast cancer, but the underlying mechanisms are not fully understood. In this study, the metabolomic and transcriptomic characteristics of a large panel of human breast cancer xenograft models were mapped, with focus on choline metabolism. <br> Methods: Tumor specimens from 34 patient-derived xenograft models were collected ...
    • 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 ...
    • Longitudinal magnetic resonance imaging-based assessment of vascular changes and radiation response in androgen-sensitive prostate carcinoma xenografts under androgen-exposed and androgen-deprived conditions 

      Røe, Kathrine; Seierstad, Therese; Kristian, Alexandr; Mikalsen, Lars Tore G; Mælandsmo, Gunhild; van der Kogel, Albert; Ree, Anne Hansen; Olsen, Dag Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2010-10)
      Prostate cancer (PCa) patients receive androgen-deprivation therapy (ADT) to reduce tumor burden. However, complete eradication of PCa is unusual, and recurrent disease is evident within approximately 2 years in high-risk patients. Clinical evidence suggests that combining ADT with radiotherapy improves local control and disease-free survival in these patients compared with radiotherapy alone. ...
    • Metabolic biomarkers for response to PI3K inhibition in basal-like breast cancer 

      Moestue, Siver Andreas; Dam, Cornelia Gerarda; Gorad, Saurabh Sayajirao; Kristian, Alexandr; Bofin, Anna M.; Mælandsmo, Gunhild; Engebråten, Olav; Gribbestad, Ingrid S; Bjørkøy, Geir (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Introduction: The phosphatidylinositol 3-kinase (PI3K) pathway is frequently activated in cancer cells through numerous mutations and epigenetic changes. The recent development of inhibitors targeting different components of the PI3K pathway may represent a valuable treatment alternative. However, predicting efficacy of these drugs is challenging, and methods for therapy monitoring are needed. ...
