      Introduction Acquired cancer therapy resistance evolves under selection pressure of immune surveillance and favors mechanisms that promote drug resistance through cell survival and immune evasion. AXL receptor tyrosine ...
    • Bortezomib abrogates temozolomide-induced autophagic flux through an ATG5 dependent pathway 

      Rahman, Mohummad Aminur; Engelsen, Agnete; Sarowar, Shahin; Bindesbøll, Christian; Birkeland, Even; Goplen, Dorota; Lotsberg, Maria Lie; Knappskog, Stian; Simonsen, Anne Gjøen; Enger, Martha (Journal article; Peer reviewed, 2022)
      Introduction: Glioblastoma (GBM) is invariably resistant to temozolomide (TMZ) chemotherapy. Inhibiting the proteasomal pathway is an emerging strategy to accumulate damaged proteins and inhibit their lysosomal degradation. ...
    • Bortezomib administered prior to temozolomide depletes MGMT, chemosensitizes glioblastoma with unmethylated MGMT promoter and prolongs animal survival 

      Rahman, Mohummad Aminur; Gras Navarro, Andrea; Brekke, Jorunn; Engelsen, Agnete; Bindesbøll, Christian; Sarowar, Shahin; Bahador, Marzieh; Bifulco, Ersilia; Goplen, Dorota; Waha, Andreas; Lie, Stein Atle; Gjertsen, Bjørn Tore; Selheim, Frode; Enger, Per Øyvind; Simonsen, Anne; Enger, Martha Chekenya (Peer reviewed; Journal article, 2019-08-15)
      Background Resistance to temozolomide (TMZ) is due in part to enhanced DNA repair mediated by high expression of O6-methyl guanine DNA methyltransferase (MGMT) that is often characterised by unmethylated promoter. Here, ...
    • Decoding cancer's camouflage: epithelialmesenchymal plasticity in resistance to immune checkpoint blockade 

      Lotsberg, Maria Lie; Rayford, Austin James; Thiery, Jean Paul; Bellaggia, Giuliana; Peters, Stacey D'Mello; Lorens, James; Chouaib, Salem; Terry, Stéphane; Engelsen, Agnete (Journal article, 2020)
      Epithelial-mesenchymal plasticity (EMP) of cancer cells contributes to cancer cell heterogeneity, and it is well established that EMP is a critical determinant of acquired resistance to cancer treatment modalities including ...
    • 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 ...
    • NK cells with KIR2DS2 immunogenotype have a functional activation advantage to efficiently kill glioblastoma and prolong animal survival 

      Gras Navarro, Andrea; Kmiecik, Justyna; Leiss, Lina Wik; Zelkowski, Mateusz; Engelsen, Agnete; Bruserud, Øystein; Zimmer, Jacques; Enger, Per Øyvind; Chekenya, Martha (Peer reviewed; Journal article, 2014-12)
      Glioblastomas (GBMs) are lethal brain cancers that are resistant to current therapies. We investigated the cytotoxicity of human allogeneic NK cells against patient-derived GBM in vitro and in vivo, as well as mechanisms ...
