    • Detection of phenotype-specific therapeutic vulnerabilities in breast cells using a CRISPR loss-of-function screen 

      Barkovskaya, Anna; Goodwin, Craig; Seip, Kotryna; Hilmarsdòttir, Bylgja; Pettersen, Solveig; Stalnecker, Clint; Engebraaten, Olav; Briem, Eirikur; Der, Channing J; Moestue, Siver Andreas; Guðjónsson, Þórarinn; Mælandsmo, Gunhild Mari; Prasmickaite, Lina (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-24)
      Cellular phenotype plasticity between the epithelial and mesenchymal states has been linked to metastasis and heterogeneous responses to cancer therapy, and remains a challenge for the treatment of triple-negative breast cancer (TNBC). Here, we used isogenic human breast epithelial cell lines, D492 and D492M, representing the epithelial and mesenchymal phenotypes, respectively. We employed a CRISPR-Cas9 ...

    • Glutamine to proline conversion is associated with response to glutaminase inhibition in breast cancer 

      Grinde, Maria Tunset; Hilmarsdòttir, Bylgja; Tunset, Hanna Maja; Henriksen, Ida Marie; Kim, Jana; Haugen, Mads Haugland; Rye, Morten Beck; Mælandsmo, Gunhild Mari; Moestue, Siver Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-14)
      <p><i>Introduction - </i>Glutaminase inhibitors target cancer cells by blocking the conversion of glutamine to glutamate, thereby potentially interfering with anaplerosis and synthesis of amino acids and glutathione. The drug CB-839 has shown promising effects in preclinical experiments and is currently undergoing clinical trials in several human malignancies, including triple-negative breast cancer ...

    • Metabolic re-wiring of isogenic breast epithelial cell lines following epithelial to mesenchymal transition 

      Haldorsson, Skarphedinn; Rohatgi, Neha; Magnusdottir, Manuela; Choudhary, Kumari; Gudjónsson, Thorarinn; Knutsen, Erik; Barkovskaya, Anna; Hilmarsdòttir, Bylgja; Perander, Maria; Mælandsmo, Gunhild; Gudmundsson, Steinn; Rolfsson, Ottar (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-18)
      Epithelial to mesenchymal transition (EMT) has implications in tumor progression and metastasis. Metabolic alterations have been described in cancer development but studies focused on the metabolic re-wiring that takes place during EMT are still limited. We performed metabolomics profiling of a breast epithelial cell line and its EMT derived mesenchymal phenotype to create genome-scale metabolic ...

    • O-GlcNAc Transferase Inhibition Differentially Affects Breast Cancer Subtypes 

      Barkovskaya, Anna; Seip, Kotryna; Hilmarsdòttir, Bylgja; Mælandsmo, Gunhild Mari; Moestue, Siver Andreas; Itkonen, Harri (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-05)
      Post-translational modifcation of intracellular proteins with a single N-acetylglucosamine sugar (O-GlcNAcylation) regulates signaling, proliferation, metabolism and protein stability. In breast cancer, expression of the enzyme that catalyzes O-GlcNAcylation – O-GlcNAc-transferase (OGT), and the extent of protein O-GlcNAcylation, are upregulated in tumor tissue, and correlate with cancer progression. ...
