    • Agnoprotein of polyomavirus BK interacts With proliferating cell nuclear antigen and inhibits DNA replication 

      Gerits, Nancy; Johannessen, Mona; Tümmler, Conny; Walquist, Mari; Kostenko, Sergiy; Snapkov, Igor; van Loon, Barbara; Ferrari, Elena; Hübscher, Ulrich; Moens, Ugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-01)
      Background: The human polyomavirus BK expresses a 66 amino-acid peptide referred to as agnoprotein. Though mutants lacking agnoprotein are severely reduced in producing infectious virions, the exact function of this peptide remains incompletely understood. To elucidate the function of agnoprotein, we searched for novel cellular interaction partners. <p>Methods: Yeast-two hybrid assay was performed ...

    • The blood transcriptome prior to ovarian cancer diagnosis: A case-control study in the NOWAC postgenome cohort 

      Jareid, Mie Linnea; Snapkov, Igor; Holden, Marit; Busund, Lill-Tove Rasmussen; Lund, Eiliv; Nøst, Therese Haugdahl (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-27)
      Epithelial ovarian cancer (EOC) has a 5-year relative survival of 50%, partly because markers of early-stage disease are not available in current clinical diagnostics. The aim of the present study was to investigate whether EOC is associated with transcriptional profiles in blood collected up to 7 years before diagnosis. For this, we used RNA-stabilized whole blood, which contains circulating immune ...

    • Each pregnancy linearly changes immune gene expression in the blood of healthy women compared with breast cancer patients 

      Lund, Eiliv; Nakamura, Aurelie; Snapkov, Igor; Thalabard, Jean-Christophe; Olsen, Karina Standahl; Holden, Lars; Holden, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-30)
      <p><i>Background</i>: There is a large body of evidence demonstrating long-lasting protective effect of each full-term pregnancy (FTP) on the development of breast cancer (BC) later in life, a phenomenon that could be related to both hormonal and immunological changes during pregnancies. In this work, we studied the pregnancy-associated differences in peripheral blood gene expression profiles between ...

    • FITC conjugation markedly enhances hepatic clearance of N-formyl peptides 

      Øie, Cristina Ionica; Snapkov, Igor; Elvevold, Kjetil; Sveinbjørnsson, Baldur; Smedsrød, Bård (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-05)
      In both septic and aseptic inflammation, N-formyl peptides may enter the circulation and induce a systemic inflammatory response syndrome similar to that observed during septic shock. The inflammatory response is brought about by the binding of N-formyl peptide to formyl peptide receptors (FPRs), specific signaling receptors expressed on myeloid as well as non-myeloid cells involved in the ...

    • Inhibition of chemerin/CMKLR1 axis in neuroblastoma cells reduces clonogenicity and cell viability in vitro and impairs tumor growth in vivo 

      Tümmler, Conny; Snapkov, Igor; Wickström, Malin; Moens, Ugo; Ljungblad, Linda; Elfman, Maria; Winberg, Jan-Olof; Kogner, Per; Johnsen, John Inge; Sveinbjørnsson, Baldur (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-27)
      Pro-inflammatory cells, cytokines, and chemokines are essential in promoting a tumor supporting microenvironment. Chemerin is a chemotactic protein and a natural ligand for the receptors CMKLR1, GPR1, and CCRL2. The chemerin/CMKLR1 axis is involved in immunity and inflammation, and it has also been implicated in obesity and cancer.<p> In neuroblastoma, a childhood tumor of the peripheral nervous ...

    • The role of formyl peptide receptor 1 (FPR1) in neuroblastoma tumorigenesis 

      Snapkov, Igor; Öqvist, Carl Otto; Figenschau, Yngve Anton; Kogner, Per; Johnsen, John Inge; Sveinbjørnsson, Baldur (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-18)
      Background: Formyl peptide receptor 1 (FPR1) is a G protein-coupled receptor mainly expressed by the cells of myeloid origin, where it mediates the innate immune response to bacterial formylated peptides. High expression of FPR1 has been detected in various cancers but the function of FPR1 in tumorigenesis is poorly understood. Methods: Expression of FPR1 in neuroblastoma cell lines and primary ...

    • The role of inflammatory pathways in neuroblastoma tumorigenesis 

      Snapkov, Igor (Doctoral thesis; Doktorgradsavhandling, 2016-09-23)
      Neuroblastoma er en type nervecellekreft hos barn. Den har en svært kompleks biologisk heterogenisitet og er i noen tilfeller resistent mot cellegift. Den aggressive varianten av neuroblastoma er vanskelig å behandle, og dødeligheten er relativ høy. Det betyr at behovet for alternative behandlingsstrategier er stort. Gjennom økt biologisk forståelse kan man utvikle mer målrettede behandlinger som ...

    • Signals of Death - Post-Diagnostic Single Gene Expression Trajectories in Breast Cancer - A Proof of Concept 

      Lund, Eiliv; Holden, Marit; Thalabard, Jean-Christophe; Rasmussen Busund, Lill-Tove; Snapkov, Igor; Holden, Lars (Chapter; Bokkapittel, 2020-12-08)
      Using the time-dependent dynamics of gene expression from immune cells in blood, we aimed to explore single gene expression trajectories as biomarkers for death after a diagnosis of breast cancer introducing a new statistical method denoted Difference in Time Development Statistics (DTDS). This shows as proof of principle that the gene expression profiles from immune cells in blood differed in the ...
