Epithelial to mesenchymal transition (EMT) is associated with attenuation of succinate dehydrogenase (SDH) in breast cancer through reduced expression of SDHC
Røsland, Gro Vatne; Dyrstad, Sissel Elisabeth; Tusubira, Deusdedit; Helwa, Reham; Tan, Tuan Zea; Lotsberg, Maria Lie; Pettersen, Ina Katrine Nitschke; Berg, Anna; Kindt, Charlotte; Hoel, Fredrik; Jacobsen, Kristine; Arason, Ari Jon; Engelsen, Agnete; Ditzel, Henrik J.; Lønning, Per Eystein; Krakstad, Camilla; Thiery, Jean Paul; Lorens, James; Knappskog, Stian; Tronstad, Karl Johan (Peer reviewed; Journal article, 2019-06-01)Background: Epithelial to mesenchymal transition (EMT) is a well-characterized process of cell plasticity that may involve metabolic rewiring. In cancer, EMT is associated with malignant progression, tumor heterogeneity, ... -
Intrinsic Differences in Spatiotemporal Organization and Stromal Cell Interactions Between Isogenic Lung Cancer Cells of Epithelial and Mesenchymal Phenotypes Revealed by High-Dimensional Single-Cell Analysis of Heterotypic 3D Spheroid Models
Lotsberg, Maria Lie; Røsland, Gro Vatne; Rayford, Austin James; Dyrstad, Sissel Elisabeth; Ekanger, Camilla Tvedt; Lu, Ning; Frantz, Kirstine; Stuhr, Linda Elin Birkhaug; Ditzel, Henrik J.; Thiery, Jean Paul; Akslen, Lars Andreas; Lorens, James; Engelsen, Agnete (Journal article; Peer reviewed, 2022)The lack of inadequate preclinical models remains a limitation for cancer drug development and is a primary contributor to anti-cancer drug failures in clinical trials. Heterotypic multicellular spheroids are three-dimensional ... -
Regulation and quantification of cellular mitochondrial morphology and content
Tronstad, Karl Johan; Nooteboom, Marco; Hodneland, Linn I.; Nikolaisen, Julie; Sokolewicz, Maciek; Grefte, Sander; Pettersen, Ina Katrine Nitschke; Dyrstad, Sissel Elisabeth; Hoel, Fredrik; Willems, Peter H.G.M.; Koopman, Werner J.H. (Peer reviewed; Journal article, 2014)Mitochondria play a key role in signal transduction, redox homeostasis and cell survival, which extends far beyond their classical functioning in ATP production and energy metabolism. In living cells, mitochondrial content ... -
A study on metabolic rewiring in cancer cell plasticity
Dyrstad, Sissel Elisabeth (Doctoral thesis, 2020-08-21)Adaptation of cellular energetics is an important feature of tumorigenesis as a vast supply of nutrients is needed to accommodate increased growth. Essential energy pathways includes glucose, fatty acid and amino acid ... -
Upregulated PDK4 expression is a sensitive marker of increased fatty acid oxidation
Pettersen, Ina Katrine Nitschke; Tusubira, Deusdedit; Ashrafi, Hanan; Dyrstad, Sissel Elisabeth; Hansen, Lena; Liu, Xiao-Zheng; Hodneland, Linn I.; Løvsletten, Nils Gunnar; Berge, Kjetil; Wergedahl, Hege; Bjørndal, Bodil; Fluge, Øystein; Bruland, Ove; Rustan, Arild; Halberg, Nils; Røsland, Gro Vatne; Berge, Rolf Kristian; Tronstad, Karl Johan (Peer reviewed; Journal article, 2019)Fatty acid oxidation is a central fueling pathway for mitochondrial ATP production. Regulation occurs through multiple nutrient- and energy-sensitive molecular mechanisms. We explored if upregulated mRNA expression of the ...
