  1. 1. Molecular regulation of epithelial tube size

    Författare :Erika Tång Hallbäck; Göteborgs universitet; []
    Nyckelord :Drosophila; tube shape; trachea; chitin; luminal matrix; epithelial tubes; morphogenesis; chloride channel; subapical actin;

    Sammanfattning : In nature, epithelial tubes are vital structures in organ design and are required for transport of gases and liquids in organs, such as the vascular system, the vertebrate lung and the kidneys. The tubular epithelium is single layered, but is often reinforced by layers of muscular support. LÄS MER

  3. 2. 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. 3. Pelvic inflammatory disease and epithelial ovarian tumors

    Författare :Sarah Jonsson; Annika Idahl; Eva Lundin; Håkan Jonsson; Christer Borgfeldt; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Epithelial ovarian cancer and borderline ovarian tumors consist of several histotypes in which high-grade serous carcinoma is the most common. The majority of epithelial ovarian tumors are considered to originate in the fimbriated end of the fallopian tubes. What initiates these tumors is far from completely understood. LÄS MER

  5. 4. 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.

  7. 5. New roles for apical secretion and extracellular matrix assembly in Drosophila epithelial morphogenesis

    Författare :Satish Arcot Jayaram; Christos Samakovlis; Catherine Rabouille; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : Branched tubular organs, such as the lung and vascular system fulfill the respiratory needs of most animals. Optimal tissue function relies on the uniform sizes and shapes of the constituting branches in each organ. LÄS MER
