    • Serum levels of inflammation-related markers and metabolites predict response to neoadjuvant chemotherapy with and without bevacizumab in breast cancers 

      Nome, Marianne Eikhom; Euceda, Leslie R.; Jabeen, Shakila; Debik, Julia; Bathen, Tone Frost; Giskeødegård, Guro F.; Tasken, Kristin Austlid; Mælandsmo, Gunhild Mari; Halvorsen, Bente; Yndestad, Arne; Borgen, Elin; Garred, Øystein; Aukrust, Pål; Ueland, Thor; Engebraaten, Olav; Kristensen, Vessela N.; Tekpli, Xavier (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-24)
      Angiogenesis is necessary for tumor growth and has been targeted in breast cancer; however, it is unclear which patients will respond and benefit from antiangiogenic therapy. We report noninvasive monitoring of patient response to neoadjuvant chemotherapy given alone or in combination with anti‐vascular endothelial growth factor (bevacizumab) in a randomized clinical trial. At four time points during ...

      Given the anthropometric differences between men and women and previous evidence of sex-difference in genetic effects, we conducted a genome-wide search for sexually dimorphic associations with height, weight, body mass index, waist circumference, hip circumference, and waist-to-hip-ratio (133,723 individuals) and took forward 348 SNPs into follow-up (additional 137,052 individuals) in a total ...

    • Short-term sequence evolution and vertical inheritance of the Naegleria twin-ribozyme group I intron 

      Wikmark, Odd-Gunnar; De Jonckheere, Johan F.; Einvik, Christer; Johansen, Steinar D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-05-02)
      Background Ribosomal DNA of several species of the free-living Naegleria amoeba harbors an optional group I intron within the nuclear small subunit ribosomal RNA gene. The intron (Nae.S516) has a complex organization of two ribozyme domains (NaGIR1 and NaGIR2) and a homing endonuclease gene (NaHEG). NaGIR2 is responsible for intron excision, exon ligation, and full-length intron RNA circularization, ...

    • Shotgun-metagenomics based prediction of antibiotic resistance and virulence determinants in Staphylococcus aureus from periprosthetic tissue on blood culture bottles 

      Sanabria-Moreno, Adriana Maria; James Peter, Jessin Janice; Hjerde, Erik; Simonsen, Gunnar Skov; Hanssen, Anne Merethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-21)
      Shotgun-metagenomics may give valuable clinical information beyond the detection of potential pathogen(s). Identification of antimicrobial resistance (AMR), virulence genes and typing directly from clinical samples has been limited due to challenges arising from incomplete genome coverage. We assessed the performance of shotgun-metagenomics on positive blood culture bottles (n = 19) with periprosthetic ...

    • Shotgun-Metagenomics on Positive Blood Culture Bottles Inoculated With Prosthetic Joint Tissue: A Proof of Concept Study 

      Sanabria-Moreno, Adriana Maria; Hjerde, Erik; Johannessen, Mona; Sollid, Johanna U Ericson; Simonsen, Gunnar Skov; Hanssen, Anne Merethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-17)
      Clinical metagenomics is actively moving from research to clinical laboratories. It has the potential to change the microbial diagnosis of infectious diseases, especially when detection and identification of pathogens can be challenging, such as in prosthetic joint infection (PJI). The application of metagenomic sequencing to periprosthetic joint tissue (PJT) specimens is often challenged by low ...

      Sletten, Elise Thoresen; Arnes, Marit; Lyså, Lena Marianne Myreng; Larsen, Marthe; Ørbo, Anne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-25)
      <p><i>Objective - </i>After successful progestin therapy for endometrial hyperplasia (EH), the risk of relapse remains. We aimed to assess if immunohistochemical (IHC) expression of progesterone receptor isoforms, PR‐A and PR‐B, in endometrial glands and stroma in pre‐treatment endometrial biopsies was related to relapse of EH. <p><i>Design and setting - </i>Biopsy material originated from women ...

    • Silenced vanA gene cluster on a transferable plasmid cause outbreak of vancomycin variable enterococci 

      Sivertsen, Audun; Pedersen, Torunn Annie; Larssen, Kjersti Wik; Bergh, Kåre; Rønning, Torunn Gresdal; Radtke, Andreas; Hegstad, Kristin (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-02)
      We report an outbreak of vancomycin-variable vanA+ enterococci (VVE) able to escape phenotypic detection by current guide- lines and demonstrate the molecular mechanisms for in vivo switching into vancomycin resistance and horizontal spread of the vanA cluster. Forty-eight vanA+ Enterococcus faecium isolates and one Enterococcus faecalis isolate were analyzed for clonality with pulsed-field ...

    • Silencing of Renal DNaseI in Murine Lupus Nephritis Imposes Exposure of Large Chromatin Fragments and Activation of Toll Like Receptors and the Clec4e 

      Thiyagarajan, Dhivya; Fismen, Silje; Seredkina, Natalya; Jacobsen, Søren; Elung-Jensen, Thomas; Kamper, Anne-Lise; Fenton, Christopher Graham; Rekvig, Ole Petter; Mortensen, Elin Synnøve (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Recent studies demonstrate that transformation of mild lupus nephritis into end-stage disease is imposed by silencing of renal DNaseI gene expression in (NZBxNZW)F1 mice. Down-regulation of DNaseI results in reduced chromatin fragmentation, and in deposition of extracellular chromatin-IgG complexes in glomerular basement membranes in individuals that produce IgG anti-chromatin antibodies. The main ...

    • Silencing Viral MicroRNA as a Novel Antiviral Therapy? 

      Moens, Ugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2009-03-20)
      Viruses are intracellular parasites that ensure their existence by converting host cells into viral particle producing entities or into hiding places rendering the virus invisible to the host immune system. Some viruses may also survive by transforming the infected cell into an immortal tumour cell. MicroRNAs are small non-coding transcripts that function as posttranscriptional regulators of gene ...

    • Simultaneous Detection of Zinc and Its Pathway Metabolites Using MALDI MS Imaging of Prostate Tissue 

      Andersen, Maria Karoline; Krossa, Sebastian; Høiem, Therese Stork; Buchholz, Rebecca; Claes, Britt S.R.; Balluff, Benjamin; Ellis, Shane; Richardsen, Elin; Bertilsson, Helena; Heeren, Ron M.A.; Bathen, Tone Frost; Karst, Uwe; Giskeødegård, Guro F.; Tessem, May-Britt (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-16)
      Levels of zinc, along with its mechanistically related metabolites citrate and aspartate, are widely reported as reduced in prostate cancer compared to healthy tissue and are therefore pointed out as potential cancer biomarkers. Previously, it has only been possible to analyze zinc and metabolites by separate detection methods. Through matrix-assisted laser desorption/ionization mass spectrometry ...

    • SIRT1 - a new mammalian substrate of nuclear autophagy 

      Wang, Lu; Xu, Caiyue; Johansen, Terje; Berger, Shelley L.; Dou, Zhixun (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-20)
      Macroautophagic/autophagic degradation of nuclear components (or nuclear autophagy) is a poorly understood area in autophagy research. We previously reported the nuclear lamina protein LMNB1 (lamin B1) as a nuclear autophagy substrate in primary human cells, stimulating the investigation of nuclear autophagy in the mammalian system. We recently reported the sirtuin protein SIRT1 as a new selective ...

    • SIRT1 is downregulated by autophagy in senescence and ageing
