Drosophila

  • RESEARCH ARTICLE
    Preference for and learning of amino acids in larval Drosophila
    Nana Kudow, Daisuke Miura, Michael Schleyer, Naoko Toshima, Bertram Gerber, Teiichi Tanimura
    Biology Open 2017 6: 365-369; doi: 10.1242/bio.020412

    Summary: Drosophila larvae show positive preference but for a few individual amino acids. The preference partially changes depending on larval stage and deprivation. In learning experiments, all 20 tested amino acids were equally rewarding.

  • METHODS & TECHNIQUES
    Quantitative microscopy uncovers ploidy changes during mitosis in live Drosophila embryos and their effect on nuclear size
    Wee Choo Puah, Rambabu Chinta, Martin Wasser
    Biology Open 2017 6: 390-401; doi: 10.1242/bio.022079

    Summary: A new 3D time-lapse microscopy image analysis pipeline consisting of nuclear segmentation, tracking, annotation and quantification revealed karyotype changes in Drosophila embryos.

  • RESEARCH ARTICLE
    Enhancing NAD+ salvage metabolism is neuroprotective in a PINK1 model of Parkinson's disease
    Susann Lehmann, Samantha H. Y. Loh, L. Miguel Martins
    Biology Open 2017 6: 141-147; doi: 10.1242/bio.022186

    Summary: Dietary supplementation with an NAD+ salvage metabolite or decreasing Parp activity suppress mitochondrial dysfunction and is neuroprotective in a PINK1 model of Parkinson's disease.

  • RESEARCH ARTICLE
    Dynamic analysis of the mesenchymal-epithelial transition of blood-brain barrier forming glia in Drosophila
    Tina Schwabe, Xiaoling Li, Ulrike Gaul
    Biology Open 2017 6: 232-243; doi: 10.1242/bio.020669

    Summary: This study examines the major steps and underlying mechanisms of mesenchymal-epithelial transition of the blood-brain-barrier forming glia in Drosophila, including the role of basal lamina, septate junctions and of trimeric G protein signaling.

  • METHODS & TECHNIQUES
    A genetically encoded biosensor for visualising hypoxia responses in vivo
    Tvisha Misra, Martin Baccino-Calace, Felix Meyenhofer, David Rodriguez-Crespo, Hatice Akarsu, Ricardo Armenta-Calderón, Thomas A. Gorr, Christian Frei, Rafael Cantera, Boris Egger, Stefan Luschnig
    Biology Open 2017 6: 296-304; doi: 10.1242/bio.018226

    Summary: This study describes a biosensor for visualising the hypoxic state of cells in vivo. They demonstrate that the Drosophila larval brain contains distinct hypoxic microenvironments that correlate with local airway supply.

  • RESEARCH ARTICLE
    Polyglutamine length-dependent toxicity from α1ACT in Drosophila models of spinocerebellar ataxia type 6
    Wei-Ling Tsou, Sultan H. Qiblawi, Ryan R. Hosking, Christopher M. Gomez, Sokol V. Todi
    Biology Open 2016 5: 1770-1775; doi: 10.1242/bio.021667

    Summary: The spinocerebellar ataxia type 6 (SCA6) protein, α1ACT, causes polyglutamine length-dependent toxicity and aggregation in new Drosophila transgenic lines, opening the door for additional studies of this disease.

  • RESEARCH ARTICLE
    Ecdysone signaling induces two phases of cell cycle exit in Drosophila cells
    Yongfeng Guo, Kerry Flegel, Jayashree Kumar, Daniel J. McKay, Laura A. Buttitta
    Biology Open 2016 5: 1648-1661; doi: 10.1242/bio.017525

    Summary: Pulsed ecdysone signaling remodels cell cycle dynamics, causing distinct primary and secondary cell cycle arrests in Drosophila cells, analogous to those observed in the wing during metamorphosis.

  • RESEARCH ARTICLE
    The impact of FOXO on dopamine and octopamine metabolism in Drosophila under normal and heat stress conditions
    Nataly E. Gruntenko, Natalya V. Adonyeva, Elena V. Burdina, Evgenia K. Karpova, Olga V. Andreenkova, Daniil V. Gladkikh, Yury Y. Ilinsky, Inga Yu Rauschenbach
    Biology Open 2016 5: 1706-1711; doi: 10.1242/bio.022038

    Summary: The transcription factor FOXO affects catecholamine metabolism under normal and heat stress conditions in D. melanogaster, and juvenile hormone (JH) is a mediator of this effect.

  • RESEARCH ARTICLE
    Amontillado is required for Drosophila Slit processing and for tendon-mediated muscle patterning
    Elly Ordan, Talila Volk
    Biology Open 2016 5: 1530-1534; doi: 10.1242/bio.020636

    Summary: The Drosophila homolog of pheromone convertase 2 (PC2), amontillado (Amon), is shown to contribute to Slit processing and further cleavage into an N-Slit, essential for Slit activity in directing muscle patterning.

  • RESEARCH ARTICLE
    Comparative evaluation of the genomes of three common Drosophila-associated bacteria
    Kristina Petkau, David Fast, Aashna Duggal, Edan Foley
    Biology Open 2016 5: 1305-1316; doi: 10.1242/bio.017673

    Summary: We examined the genomes of Drosophila-associated bacteria to identify factors that allow survival within the host. These preliminary studies may point at bacterial products that influence host health.
