      Prostate cancer diagnosis and early stratification is an important aspect to avoid undertreatment of high-risk prostate cancer patients. Major Vault Protein (MVP) has been proposed as a prognostic biomarker in prostate cancer. PTEN and the immune checkpoint protein B7-H3 interact with MVP and are important in prostate cancer progression and therapy response. We evaluated the expression of MVP by ...
    • The ubiquitin E3 ligase TRIM27 emerges as a new player in mitophagy 

      Berge, Anne Kristin McLaren; Garcia, Juncal Garcia; Sjøttem, Eva; Olsvik, Hallvard Lauritz (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-05)
      Mitochondria are the center for energy production, cell fate determination and synthesis of essential biomolecules in cells. Hence, mitochondrial quality control mechanisms are essential for cellular health. Failure of these control mechanisms may lead to damaged mitochondria that represent a threat to cell survival. Mitophagy is a selective autophagy process that removes damaged mitochondria ...
    • NBR1: The archetypal selective autophagy receptor 

      Rasmussen, Nikoline Lander; Kournoutis, Athanasios; Lamark, Trond; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-18)
      NBR1 was discovered as an autophagy receptor not long after the first described vertebrate autophagy receptor p62/SQSTM1. Since then, p62 has currently been mentioned in >10,000 papers on PubMed, while NBR1 is mentioned in <350 papers. Nonetheless, evolutionary analysis reveals that NBR1, and likely also selective autophagy, was present already in the last eukaryotic common ancestor (LECA), while ...

      Background: Rhabdomyosarcoma (RMS) is a paediatric cancer driven either by fusion proteins (e.g., PAX3-FOXO1) or by mutations in key signalling molecules (e.g., RAS or FGFR4). Despite the latter providing opportunities for precision medicine approaches in RMS, there are currently no such treatments implemented in the clinic.<p> <p>Methods: We evaluated biologic properties and targeting strategies ...
    • SLE classification criteria: Science-based icons or algorithmic distractions – an intellectually demanding dilemma 

      Rekvig, Ole Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)
      It is, so to say, not a prerogative authority assigned to SLE classification criteria that allow them to declare something definitively important about SLE. This is particularly true as criteria-based classification processes overrule the highly needed evolution of concise diagnostic criteria. It is classification criteria that allocate SLE patients into cohorts intended to describe the nature of ...
    • Comparative analysis of Vibrio cholerae isolates from Ghana reveals variations in genome architecture and adaptation of outbreak and environmental strains 

      Adade, Nana Eghele; Aniweh, Yaw; Mosi, Lydia; Valvano, Miguel A.; Duodu, Samuel; Ahator, Stephen Dela (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-13)
      Recurrent epidemics of cholera denote robust adaptive mechanisms of Vibrio cholerae for ecological shifting and persistence despite variable stress conditions.
