    • 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 ...

    • Complete mitochondrial genome sequences of the Arctic Ocean codfishes Arctogadus glacialis and Boreogadus saida reveal oriL and tRNA gene duplications 

      Breines, Ragna; Ursvik, Anita; Nymark, Marianne; Johansen, Steinar; Coucheron, Dag-Hugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-05-27)
      We have determined the complete mitochondrial genome sequences of the codWshes Arctogadus glacialis and Boreogadus saida (Order Gadiformes, Family Gadidae). The 16,644 bp and 16,745 bp mtDNAs, respectively, contain the same set of 37 structural genes found in all vertebrates analyzed so far. The gene organization is conserved compared to other Gadidae species, but with one notable exception. ...

    • Plasma profile of microRNA after supplementation with high doses of vitamin D3 for 12 months 

      Jorde, Rolf; Svartberg, Johan; Joakimsen, Ragnar Martin; Coucheron, Dag-Hugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-05-17)
      Background: Recently a large number of short non-coding-RNAs (microRNAs, (miRNA)) have been identified. These miRNAs act as post-transcriptional regulators where they generally have an inhibitory function. miRNAs are present in all human cells, and they are also detected in serum or plasma. The miRNAs have a broad range of actions, and their biogenesis must therefore be under tight control. One ...

    • Polyphyletic origin of the genus Physarum (Physarales, Myxomycetes) revealed by nuclear rDNA mini-chromosomal analysis and group I intron synapomorphy 

      Nandipati, Satish C R; Haugli, Kari B.; Coucheron, Dag-Hugo; Haskins, Edward F.; Johansen, Steinar (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-08-31)
      Physarales represents the largest taxonomic order among the plasmodial slime molds (myxomycetes). Physarales is of particular interest since the two best-studied myxomycete species, Physarum polycephalum and Didymium iridis, belong to this order and are currently subjected to whole genome and transcriptome analyses. Here we report molecular phylogeny based on ribosomal DNA (rDNA) sequences that ...
