  2. 1. Molecular regulation of epithelial tube size

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

    Abstract : 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. READ MORE

  4. 2. Genetic and molecular regulation of epithelial tube morphogenesis

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

    Abstract : 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. READ MORE

  5. 3. Grainy head target genes in epithelial morphogenesis and wound healing

    Author : Shenqiu Wang; Christos Samakovlis; Paul Martin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; grh; targets; epidermal wound repair; tracheal tube size control; local immune responses; stit; verm; serp; PGRP-LC; CecA-LacZ; Developmental biology; Utvecklingsbiologi; utvecklingsbiologi; Developmental Biology;

    Abstract : grainy head (grh) genes encode a family of transcription factors conserved from fly to human. Drosophila grh is the founding member of this gene family and has multiple functions, including tracheal tube size control, epidermal barrier formation and reconstruction after wounding. READ MORE

  6. 4. Nuclear pore membrane glycoprotein 210 as a new marker for epithelial cells

    Author : Magnus Olsson; Neus Visa; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Nuclear pore complex; gp210; Nulp1; epithelial cells; kidney development; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Epithelial cell polarisation is a prerequisite for the branching morphogenesis in several organs. Differential screening techniques were used to identify genes, which are upregulated during induction of epithelium in early kidney development. READ MORE

  7. 5. Regulation of epithelial morphogenesis in Drosophila by the Emp scavenger receptor

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

    Abstract : 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.
