  1. 21. Gene regulation during development by chromatin and the Super Elongation Complex

    Författare :Olle Dahlberg; Mattias Mannervik; Peter Gergen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila development; gene regulation; transcription; chromatin; P-TEFb; Super Elongation Complex; KDM4A; H3K36me3; H3K14ac; histone replacement; utvecklingsbiologi; Developmental Biology;

    Sammanfattning : Developmental processes are carefully controlled at the level of transcription to ensure that the fertilized egg develops into an adult organism. The mechanisms that controls transcription of protein-coding genes ultimately ensure that the Pol II machine synthesizes mRNA from the correct set of genes in every cell type. LÄS MER

  3. 22. The Molecular Mechanism of Aggression and Feeding Behaviour in Drosophila melanogaster

    Författare :Philip Goergen; Helgi Schiöth; Michael Williams; Simon Tuck; Uppsala universitet; []
    Nyckelord :Drosophila; aggression; obesity; homeostasis;

    Sammanfattning : Obesity is a complex disorder which has become a growing health concern. Twin studies have demonstrated a strong genetic component to the development of obesity and genome wide association studies have identified several genetic loci associated with it. However, most of these loci are still poorly understood in a functional context. LÄS MER

  4. 23. 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. 24. Expression and function of Suppressor of zeste 12 in Drosophila melanogaster

    Författare :Sa Chen; Åsa Rasmuson-Lestander; Jan Larsson; Mattias Mannervik; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epigenetics; histone; polycomb; Drosophila; Suppressor of zeste 12; Genetics; Genetik; genetik; Genetics;

    Sammanfattning : The development of animals and plants needs a higher order of regulation of gene expression to maintain proper cell state. The mechanisms that control what, when and where a gene should (or should not) be expressed are essential for correct organism development. LÄS MER

  7. 25. From Cell Shape to Body Shape: Epithelial Morphogenesis in Drosophila melanogaster

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

    Sammanfattning : 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. LÄS MER
