  1. 16. Steady, ready, go - proteomics of etioplast inner membranes reveals a high readiness for light

    Författare :Lisa A. Blomqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chloroplast; etioplast; NADPH:protochlorophyllide oxidoreductase; prolamellar body; proteomics; prothylakoid; transmembrane; Triticum aestivum; wheat;

    Sammanfattning : Light is essential for development of photosynthetically active chloroplasts. In the absence of light proplastids develop into etioplasts which are readily transformed into chloroplasts upon illuminat... LÄS MER

  3. 17. Genetic and molecular regulation of epithelial tube morphogenesis

    Författare :Anna Tonning; Göteborgs universitet; []
    Nyckelord :epithelial tube morphogenesis; trachea; Drosophila; chitin; chitin synthase; apical extracellular matrix; paracellular diffusion barrier; tube expansion; septate junctions;

    Sammanfattning : Networks of epithelial tubes, such as the vertebrate lung, kidney and vascular system, enable transport of gases and nutrients to all tissues in the body. These tubes are built up by a single layer of polarized epithelial cells, with the apical membrane facing the lumen. LÄS MER

  4. 18. Regulation of epithelial morphogenesis in Drosophila by the Emp scavenger receptor

    Författare :Ana Sofia Pinheiro; Christos Samakovlis; Sofia Araújo; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Emp; scavenger receptor; CD36; cytoskeleton; Src kinase; Diap; DrICE; Hipo Yki; endocytosis; Drosophila; airways; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The respiratory system of Drosophila melanogaster, the trachea, is widely used as a model system to study the development of branched tubular organs. Airway maturation in Drosophila entails a series of sequential events: first, a massive apical secretion of luminal proteins initiates diametric tube expansion, second an endocytic wave removes luminal proteins and finally liquid clearance and gas filling converts the nascent epithelial tubes to a functional respiratory organ.

  5. 19. Renal Klotho in mineral metabolism

    Författare :Risul Amin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Calcium and phosphorous are critical elements in a number of physiological processes, including maintenance of bone structure, cell signaling and energy metabolism. Their endocrine regulation is tightly controlled through a number of feedback mechanisms involving parathyroid hormone (PTH), vitamin D and the recently discovered fibroblast growth factor 23 (FGF23).

  7. 20. Studies of ADAMTS13 expression and activity in the kidney

    Författare :Ramesh Tati; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADAMTS13; von WIllebrand factor; thrombotic thrombocytopenic purpura;

    Sammanfattning : Von Willebrand factor (VWF) is an abundant plasma glycoprotein involved in platelet adhesion and aggregation at sites of vascular injury. ADAMTS13 is the sole physiological VWF-cleaving protease, thus regulating the size of thrombus growth. LÄS MER
