      Methods for automatic analysis of clinical data are usually targeted towards a specific modality and do not make use of all relevant data available. In the field of male human reproduction, clinical and biological data are ...
    • Optic atrophy 1 is an A-kinase anchoring protein on lipid droplets that mediates adrenergic control of lipolysis 

      Pidoux, Guillaume; Witczak, Oliwia; Jarnæss, Elisabeth; Myrvold, Linda; Urlaub, Henning; Stokka, Anne Jorunn; Küntziger, Thomas Michel; Tasken, Kjetil (EMBO Journal;30 (21), Journal article; Peer reviewed, 2011-10-07)
      Adrenergic stimulation of adipocytes yields a cAMP signal that activates protein kinase A (PKA). PKA phosphorylates perilipin, a protein localized on the surface of lipid droplets that serves as a gatekeeper to regulate ...
