  2. 1. From Cell Shape to Body Shape: Epithelial Morphogenesis in Drosophila melanogaster

    Author : Shai Mulinari; Sociologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Odd-skipped; morphogenesis; Hedgehog; segment boundaries; segmental grooves; Actin; Drosophila; DRhoGEF2; Myosin; Diaphanous; Rho GTPase; cytoskeleton; Rho1;

    Abstract : Embryonic development is associated with extensive rearrangements of tissues. The driving force for these rearrangements is generated by a dynamic reorganization of the Actin cytoskeleton of individual cells. READ MORE

  4. 2. Airway maturation in Drosophila

    Author : Katarína Tiklová; Christos Samakovlis; Richard Fehon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; utvecklingsbiologi; Developmental Biology;

    Abstract : Tubes are a fundamental unit of organ design. Most of our major organs like the lung, kidney and vasculature are composed primarily of tubes. To identify fundamental biological principles of tubular organ formation we used the respiratory organ of Drosophila melanogaster, the trachea.This work dissects embryonic trachea maturation.

  5. 3. 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.

  6. 4. 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

  7. 5. RNA-based mechanisms of chromatin and gene regulation

    Author : Jordi Planells Rodrigo; Neus Visa; Simon Elsässer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gene regulation; chromatin; non-coding RNAs; genome-wide studies; Drosophila melanogaster; ADAR3; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Cells regulate gene expression in a particular spatio-temporal manner by executing specific transcriptional programs. The different transcriptional programs allow the generation of the different cell types in multicellular organisms and mediate particular cellular responses to external cues such as viral infections.
