      Diab, Joseph; Hansen, Terkel; Goll, Rasmus; Stenlund, Hans; Ahnlund, Maria; Jensen, Einar; Moritz, Thomas; Florholmen, Jon; Forsdahl, Guro (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-11)
      <p><i>Background - </i>The onset of ulcerative colitis (UC) is associated with alterations in lipid metabolism and a disruption of the balance between pro- and anti-inflammatory molecules. Only a few studies describe the mucosal lipid biosignatures during active UC. Moreover, the dynamics of lipid metabolism in the remission state is poorly defined. Therefore, this study aims to characterize mucosal ...
    • Mucosal Metabolomic Profiling and Pathway Analysis Reveal the Metabolic Signature of Ulcerative Colitis 

      Diab, Joseph; Hansen, Terkel; Goll, Rasmus; Stenlund, Hans; Jensen, Einar; Moritz, Thomas; Florholmen, Jon; Forsdahl, Guro (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-27)
      The onset of ulcerative colitis (UC) is characterized by a dysregulated mucosal immune response triggered by several genetic and environmental factors in the context of host–microbe interaction. This complexity makes UC ideal for metabolomic studies to unravel the disease pathobiology and to improve the patient stratification strategies. This study aims to explore the mucosal metabolomic profile in ...
    • Polyethylene glycol (PEG) as a broad applicability marker for LC–MS/MS-based biodistribution analysis of nanomedicines 

      Hyldbakk, Astrid; Hansen, Terkel; Hak, Sjoerd; Borgos, Sven Even F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-13)
      Polyethylene glycol (PEG) conjugation (PEGylation) is a well-established strategy to improve the pharmacokinetic and biocompatibility properties of a wide variety of nanomedicines and therapeutic peptides and proteins. This broad use makes PEG an attractive ‘allround’ candidate marker for the biodistribution of such PEGylated compounds. This paper presents the development of a novel strategy for ...
    • The Presumed Polyomavirus Viroporin VP4 of Simian Virus 40 or Human BK Polyomavirus Is Not Required for Viral Progeny Release 

      Henriksen, Stian; Hansen, Terkel; Bruun, Jack-Ansgar; Rinaldo, Christine Hanssen (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-14)
      The minor capsid protein of human BK polyomavirus (BKPyV), VP2, and its N-terminally truncated form, VP3, are both important for viral entry. The closely related simian virus 40 (SV40) reportedly produces an additional truncated form of VP2/3, denoted VP4, apparently functioning as a viroporin promoting progeny release. The VP4 open reading frame is conserved in some polyomaviruses, including BKPyV. ...
    • A Quantitative Analysis of Colonic Mucosal Oxylipins and Endocannabinoids in Treatment-Naïve and Deep Remission Ulcerative Colitis Patients and the Potential Link With Cytokine Gene Expression 

      Diab, Joseph; Al-Mahdi, Rania; Gouveia, Sandra; Hansen, Terkel; Jensen, Einar; Goll, Rasmus; Moritz, Thomas; Florholmen, Jon; Forsdahl, Guro (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-22)
      <p><i>Background</i> - The bioactive metabolites of omega 3 and omega 6 polyunsaturated fatty acids (ω-3 and ω-6) are known as oxylipins and endocannabinoids (eCBs). These lipid metabolites are involved in prompting and resolving the inflammatory response that leads to the onset of inflammatory bowel disease (IBD). This study aims to quantify these bioactive lipids in the colonic mucosa and to ...
    • Ulcerative colitis: Functional analysis of the in-depth proteome 

      Schniers, Armin; Goll, Rasmus; Pasing, Yvonne; Sørbye, Sveinung; Florholmen, Jon; Hansen, Terkel (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-29)
      <p><i>Background - </i>Ulcerative colitis (UC) is one major form of inflammatory bowel disease. The cause and the pathophysiology of the disease are not fully understood and we therefor aim in this study to identify important pathophysiological features in UC from proteomics data. <p><i>Methods - </i>Colon mucosa biopsies from inflamed tissue of untreated UC patients at diagnosis and from healthy ...
