    • Expression profiling reveals Spot 42 small RNA as a key regulator in the central metabolism of Aliivibrio salmonicida 

      Hansen, Geir Åsmund; Ahmad, Rafi; Hjerde, erik; Fenton, Christopher Graham; Willassen, Nils Peder; Haugen, Peik (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Spot 42 was discovered in Escherichia coli nearly 40 years ago as an abundant, small and unstable RNA. Its biological role has remained obscure until recently, and is today implicated in having broader roles in the central and secondary metabolism. Spot 42 is encoded by the spf gene. The gene is ubiquitous in the Vibrionaceae family of gamma-proteobacteria. One member of this family, Aliivibrio ...

    • A genome-wide study of gene expression regulation in the Gram-negative fish pathogen Aliivibrio salmonicida 

      Hansen, Geir Åsmund (Doctoral thesis; Doktorgradsavhandling, 2011-10-04)
      Regulation of gene expression is essential for all bacteria to function and survive. The expression of genes into proteins is dependent on a number of steps, each of which can be subjected to regulation. In the literature much emphasis has typically been placed on transcriptional regulation, but during recent years gene regulation at the post-transcriptional level has also gained much attention. One ...
