    • Molecular interaction studies of initial electrostatic attraction between trypsin and the human PAR-2 receptor 

      Kristoffersen, Tonje Håtveit (Master thesis; Mastergradsoppgave, 2020-01-16)
      Workers in livestock and fish cultivation are at increased risk of occupational airway damage caused by proteases. Proteases, such as trypsin, activate PAR-2 which in turn triggers an inflammatory response, potentially causing airway damage over time. There has been some speculation that PAR-2 receptors easier attract trypsin form species where this enzyme has a more negative electrostatic charge. ...
    • Molecular Interactions Stabilizing the Promatrix Metalloprotease-9·Serglycin Heteromer 

      Dawadi, Rangita; Malla, Nabin; Hegge, Beate; Wushur, Imin; Berg, Eli; Svineng, Gunbjørg; Sylte, Ingebrigt; Winberg, Jan-Olof (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-12)
      Previous studies have shown that THP-1 cells produced an SDS-stable and reduction-sensitive complex between proMMP-9 and a chondroitin sulfate proteoglycan (CSPG) core protein. The complex could be reconstituted in vitro using purified serglycin (SG) and proMMP-9 and contained no inter-disulfide bridges. It was suggested that the complex involved both the FnII module and HPX domain of proMMP-9. The ...

      The dominant sex hormone testosterone is mainly metabolized by liver enzymes belonging to the uridine-diphospho (UDP) glucuronosyltransferase (UGT) family. These enzymes are the main phase II enzymes, and they have an important role in the detoxification of endogenous and exogenous compounds in humans. The aim of the present study was to improve the understanding of the binding properties of UGT2B17. ...
    • A molecular study of putative pili structures in Enterococuus faecium 

      Schei, Ingvild Kristin Midtervoll (Master thesis; Mastergradsoppgave, 2008-12)
      Infections caused by Enterococcus faecium have increased over the last few decades. In this thesis there has been an attempt to identify putative pili proteins in E. faecium. The putative genes were ligated into a pENTR vector; the insert was sequenced to check the orientation, sequence, length and ends. Then the putative genes were recombined into a pDEST vector for expression. The expression showed ...
    • Molecular targets and biological effects of PAX6 in lung cancer 

      Johannessen, Charles (Master thesis; Mastergradsoppgave, 2013-05-15)
      Lung cancer is by far the leading cause of cancer-related mortality worldwide regardless of sex, and has a dismal overall 5-year survival rate of approximately 15%. More than 85% of all lung cancers are non-small cell lung cancer (NSCLC), and about 50% of these are adenocarcinomas. Targeted treatment has shown promising results in treating certain types of NSCLC, but the overall survival is still ...

Low-level resistant isolates with the N526K substitution (group II low-rPBP3) predominate in most geographical regions, while high-level resistant isolates with the additional S385T substitution (group III high-rPBP3) are common in Japan ...
    • Multimodal super-resolution optical microscopy visualizes the close connection between membrane and the cytoskeleton in liver sinusoidal endothelial cell fenestrations 

      Mönkemöller, Viola; Øie, Cristina Ionica; Hubner, Wolfgang; Huser, Thomas Rolf; McCourt, Peter Anthony (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      Liver sinusoidal endothelial cells (LSECs) act as a filter between blood and the hepatocytes. LSECs are highly fenestrated cells; they contain transcellular pores with diameters between 50 to 200 nm. The small sizes of the fenestrae have so far prohibited any functional analysis with standard and advanced light microscopy techniques. Only the advent of super-resolution optical fluorescence microscopy ...
    • Multiple faces of succinate beyond metabolism in blood 

      Grimolizzi, Franco; Arranz, Lorena (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-28)
      Succinate is an essential intermediate of the tricarboxylic acid cycle that exerts pleiotropic roles beyond metabolism in both physiological and pathological conditions. Recent evidence obtained in mouse models shows its essential role regulating blood cell function through various mechanisms that include pseudohypoxia responses by hypoxiainducible factor-1α activation, post-translational modifications ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      While the risk of ovarian cancer clearly reduces with each full-term pregnancy, the effect of incomplete pregnancies is unclear. We investigated whether incomplete pregnancies (miscarriages and induced abortions) are associated with risk of epithelial ovarian cancer. This observational study was carried out in female participants of the European Prospective Investigation into Cancer and Nutrition ...
    • Multiple specialised goose-type lysozymes potentially compensate for an exceptional lack of chickentype lysozymes in Atlantic cod 

      Seppola, Marit; Bakkemo, Kathrine Ryvold; Mikkelsen, Helene V.; Myrnes, Bjørnar; Helland, Ronny; Irwin, David; Nilsen, Inge Waller (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-21)
      Previous analyses of the Atlantic cod genome showed unique combinations of lacking and expanded number of genes for the immune system. The present study examined lysozyme activity, lysozyme gene distribution and expression in cod. Enzymatic assays employing specific bacterial lysozyme inhibitors provided evidence for presence of g-Type, but unexpectedly not for c-Type lysozyme activity. Database ...
    • Multiscale and Multimodal Optical Imaging of the Ultrastructure of Human Liver Biopsies 

      Kong, Cihang; Bobe, Stefanie; Pilger, Christian; Lachetta, Mario; Øie, Cristina Ionica; Kirschnick, Nils; Mönkemöller, Viola; Hübner, Wolfgang; Förster, Christine; Schuttpelz, Mark; Kiefer, Friedemann; Huser, Thomas; Schulte am Esch, Jan (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-17)
      The liver as the largest organ in the human body is composed of a complex macroscopic and microscopic architecture that supports its indispensable function to maintain physiological homeostasis. Optical imaging of the human liver is particularly challenging because of the need to cover length scales across 7 orders of magnitude (from the centimeter scale to the nanometer scale) in order to fully ...
