  1. 11. Mating behaviour in Drosophila melanogaster and its implication to genetic variation

    Författare :Sven-Eric Åslund; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; drosophila melanogaster; mating behaviour; fitness; allozymes; bristles; Y chromosome; polymorphism; selection;

    Sammanfattning : Not much is known about the mechanisms affecting the genetic composition of populations of different species. To investi­gate one of these potential mechanisms, mating behaviour, the fruit fly Drosophila melanogaster, was chosen as an experimen­tal animal. LÄS MER

  3. 12. 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. 13. Signaling and transcriptional regulation of antimicrobial peptide genes in Drosophila melanogaster

    Författare :Hanna Uvell; Ylva Engström; Won-Jae Lee; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antimicrobial peptides; drosophila; immunity; transcriptiona regulation; Molecular biology; Molekylärbiologi;

    Sammanfattning : Insects rely solely on innate immune reactions for protection against infect-ing microbes in their environment. In Drosophila, one major defense mechanism is the production of a battery of antimicrobial peptides (AMPs). LÄS MER

  5. 14. 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

  7. 15. 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
