  3. 12. Molecular characterization of the Drosophila responses towards nematodes

    Författare :Md. Badrul Arefin; Ulrich Theopold; Ioannis Eleftherianos; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila; nematodes; infection; danger situations; immune response; coagulation; apoptosis; nitric oxide; leukemia; Molecular Biology; molekylärbiologi;

    Sammanfattning : A sophisticated evolutionary conserved innate immune system has evolved in insects to fight pathogens and to restrict damage in harmful (danger) situations including cancer. A significant amount of knowledge about different infection models in Drosophila has been generated in past decades, which revealed functional resemblances and implications for vertebrate systems.

  4. 13. Thioredoxins and gene regulation in the Drosophila germline

    Sammanfattning : Spermatogenesen är i många organismer en av de mest dramatiska förvandlingar som en cell kan genomgå – en vanlig, rund, diploid cell omvandlas till en nålformad, haploid cell med ett tätt packat cellmaskineri. I bananfluga, Drosophila melanogaster, innebär denna process flera karaktäristiska stadier. LÄS MER

  5. 14. Functions of Transcriptional Co-regulators in Drosophila development

    Författare :Tobias Lilja; Mattias Mannervik; Ze'ev Paroush; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transcription; Co-regulator; Development; Drosophila; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : During Drosophila development, regulation of gene expression through interplay between transcriptional activators and repressors is generating complex patterns of gene expression that leads to cell differentiation. For proper control of transcription, transcription factors bind to DNA at control regions, so called Cis Regulatory Modules (CRM). LÄS MER

  7. 15. Chromosome-wide gene regulatory mechanisms in Drosophila melanogaster

    Författare :Anna-Mia Johansson; Jan Larsson; Kristen M. Johansen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatin structure; Drosophila; POF; disage compensation; gene expression; MSL; heterochromatin; Genetics; Genetik; genetik; Genetics;

    Sammanfattning : In Drosophila there are two different chromosome-wide targeting systems, the dosage compensation system that equalizes the transcriptional output from X-linked genes between males and females, and the regulation of the 4th chromosome mediated by the POF protein.   The best studied of these two mechanisms is the dosage compensation system.
