• Blood Transcriptome Analysis of Septic Patients Reveals a Long Non-Coding Alu-RNA in the Complement C5a Receptor 1 Gene 

      Emblem, Åse; Knutsen, Erik; Jørgensen, Tor Erik; Fure, Hilde; Johansen, Steinar Daae; Brekke, Ole Lars; Mollnes, Tom Eirik; Karlsen, Bård Ove (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-29)
      Many severe inflammation conditions are complement-dependent with the complement component C5a-C5aR1 axis as an important driver. At the RNA level, the blood transcriptome undergoes programmed expression of coding and long non-coding RNAs to combat invading microorganisms. Understanding the expression of long non-coding RNAs containing Alu elements in inflammation is important for reconstructing ...

    • Characterization of mitochondrial mRNAs in codfish reveals unique features compared to mammals 

      Coucheron, Dag-Hugo; Nymark, Marianne; Breines, Ragna; Karlsen, Bård Ove; Andreassen, morten; Jørgensen, Tor Erik; Moum, Truls; Johansen, Steinar Daae (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Expression and processing of mitochondrial gene transcripts are fundamental to mitochondrial function, but information from early vertebrates like teleost fishes is essentially lacking. We have analyzed mitogenome sequences of ten codfishes (family Gadidae), and provide complete sequences from three new species (Saithe, Pollack and Blue whiting). Characterization of the mitochondrial mRNAs in Saithe ...
    • Direct small RNA signatures in extracellular vesicles from breast cancer cell lines 

      Fiskaa, Tonje; Knutsen, Erik; Nikolaisen, Malene; Jørgensen, Tor Erik; Johansen, Steinar Daae; Perander, Maria; Seternes, Ole Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-31)
      Breast cancer is a heterogeneous disease, and different subtypes of breast cancer show distinct cellular morphology, gene expression, metabolism, motility, proliferation, and metastatic potential. Understanding the molecular features responsible for this heterogeneity is important for correct diagnosis and better treatment strategies. Extracellular vesicles (EVs) and their associated molecules ...
    • Elucidating the small regulatory RNA repertoire of the sea anemone Anemonia viridis based on whole genome and small RNA sequencing 

      Urbarova, Ilona; Patel, Hardip; Forêt, Sylvain; Karlsen, Bård Ove; Jørgensen, Tor Erik; Hall-Spencer, Jason M.; Johansen, Steinar Daae (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-27)
      Cnidarians harbor a variety of small regulatory RNAs that include microRNAs (miRNAs) and PIWI-interacting RNAs (piRNAs), but detailed information is limited. Here, we report the identification and expression of novel miRNAs and putative piRNAs, as well as their genomic loci, in the symbiotic sea anemone <i>Anemonia viridis</i>. We generated a draft assembly of the <i>A. viridis</i> genome with ...
    • An evolutionary preserved intergenic spacer in gadiform mitogenomes generates a long noncoding RNA

    • Halibut mitochondrial genomes contain extensive heteroplasmic tandem repeat arrays involved in DNA recombination 

      Johansen, Steinar D.; Mjelle, Kenneth A.; Karlsen, Bård O.; Jørgensen, Tor Erik; Moum, Truls (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-01-11)
      Background: Halibuts are commercially important flatfish species confined to the North Pacific and North Atlantic Oceans. We have determined the complete mitochondrial genome sequences of four specimens each of Atlantic halibut (Hippoglossus hippoglossus), Pacific halibut (Hippoglossus stenolepis) and Greenland halibut (Reinhardtius hippoglossoides), and assessed the nucleotide variability within ...

      Objective:<br> The objective of this study was to analyse intraspecifc sequence variation of Atlantic cod mitochondrial DNA, based on a comprehensive collection of completely sequenced mitochondrial genomes. <br>Results:<br> We determined the complete mitochondrial DNA sequence of 124 cod specimens from the eastern and western part of the species’ distribution range in the North Atlantic Ocean. ...
    • Performance Comparison of Digital microRNA Profiling Technologies Applied on Human Breast Cancer Cell Lines 

      Knutsen, Erik; Fiskaa, Tonje; Ursvik, Anita; Jørgensen, Tor Erik; Perander, maria; Lund, Eiliv; Seternes, Ole Morten; Johansen, Steinar (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      MicroRNA profiling represents an important first-step in deducting individual RNA-based regulatory function in a cell, tissue, or at a specific developmental stage. Currently there are several different platforms to choose from in order to make the initial miRNA profiles. In this study we investigate recently developed digital microRNA high-throughput technologies. Four different platforms were ...
