    • TAK1 converts Sequestosome 1/p62 from an autophagy receptor to a signaling platform 

      Kehl, Stephanie R; Soos, Brandy-Lee A; Saha, Bhaskar; Choi, Seong Won; Herren, Anthony W; Johansen, Terje; Mandell, Michael A (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-25)
      The protein p62/Sequestosome 1 (p62) has been described as a selective autophagy receptor and independently as a platform for pro‐inflammatory and other intracellular signaling. How these seemingly disparate functional roles of p62 are coordinated has not been resolved. Here, we show that TAK1, a kinase involved in immune signaling, negatively regulates p62 action in autophagy. TAK1 reduces p62 ...

    • Tandvårdsturism - ökad risk för folkhälsan 

      Olsvik, Ørjan; Lund, Bodil Kristina (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-09)
      Så kallad medicinsk turism, att kombinera elektiv vård utomlands med semester, ökar kraftigt. Medicinsk turism kan skapa såväl kulturella, ekonomiska, etiska, legala och medicinska problem genom import av smittsamma sjukdomar till hemlandet. Patienter som väljer att söka vård utomlands bör vara införstådda med att det kan medföra en ökad risk att bli infekterad av antibiotikaresistenta bakterier.

    • Tezosentan reduces the microvascular filtration coefficient in isolated lungs from rats subjected to cecum ligation and puncture 

      Kuklin, Vladimir N.; Sovershaev, Mikhail; Andreasen, Thomas; Skogen, Vegard; Ytrehus, Kirsti; Bjertnæs, Lars J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2005-10-18)
      Introduction: We recently demonstrated that the non-selective endothelin-1 (ET-1) receptor blocker tezosentan antagonizes ovine acute lung injury (ALI) following infusion of endotoxin or ET-1 by reducing the enhanced lung microvascular pressure, although we could not exclude the possibility of a simultaneous decline in microvascular permeability. In the present study, our aim was to find out if ...
    • Tezosentan-induced attenuation of lung injury in endotoxemic sheep is associated with reduced activation of protein kinase C 

      Ingebretsen, Ole C.; Kuklin, Vladimir N.; Kirov, Mikhail Y.; Sovershaev, Mikhail; Andreasen, Thomas; Ytrehus, Kirsti; Bjertnæs, Lars J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2005-03-04)
      Introduction: Studies in vitro reveal that endothelin-1 (ET-1) activates the α isoform of protein kinase C (PKC-α) in cultures of endothelial cells, thereby deranging cellular integrity. Sepsis and endotoxemia are associated with increased plasma concentrations of ET-1 that induce acute lung injury (ALI). We recently reported that non-selective ET-1 receptor blockade attenuates ALI in sheep by ...

    • A third approach to gene prediction suggests thousands of additional human transcribed regions 

      Glusman, Gustavo; El-Gewely, M. Raafat; Qin, Shizhen; Siegel, Andrew F.; Roach, Jared C.; Hood, Leroy; Smit, Arian F.A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2006-03)
      The identification and characterization of the complete ensemble of genes is a main goal of deciphering the digital information stored in the human genome. Many algorithms for computational gene prediction have been described, ultimately derived from two basic concepts: (1) modeling gene structure and (2) recognizing sequence similarity. Successful hybrid methods combining these two concepts have ...
    • The third helix of the homeodomain of paired class homeodomain proteins acts as a recognition helix both for DNA and protein interactions 

      Bruun, Jack-Ansgar; Thomassen, Ernst I.s.; Kristiansen, Kurt; Tylden, Garth Daryl; Holm, Turid; Mikkola, Ingvild; Bjørkøy, Geir; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2005)
      The transcription factor Pax6 is essential for the development of the eyes and the central nervous system of vertebrates and invertebrates. Pax6 contains two DNA-binding domains; an N-terminal paired domain and a centrally located homeodomain. We have previously shown that the vertebrate paired-less isoform of Pax6 (Pax6ΔPD), and several other homeodomain proteins, interact with the full-length ...
