- Metabolic rate and hypoxia tolerance are affected by group interactions and sex in the fruit fly (Drosophila melanogaster): new data and a literature survey
Summary: Technical advances allowing oxygen consumption measurement in individual fruit flies actually take them out of their normal highly social context, resulting in higher oxygen consumption rates than in natural groups.
- Quantitative microscopy uncovers ploidy changes during mitosis in live Drosophila embryos and their effect on nuclear size
Summary: A new 3D time-lapse microscopy image analysis pipeline consisting of nuclear segmentation, tracking, annotation and quantification revealed karyotype changes in Drosophila embryos.
- Preference for and learning of amino acids in larval Drosophila
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.
- A genetically encoded biosensor for visualising hypoxia responses in vivo
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.
- Dynamic analysis of the mesenchymal-epithelial transition of blood-brain barrier forming glia in Drosophila
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.
- Enhancing NAD+ salvage metabolism is neuroprotective in a PINK1 model of Parkinson's disease
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.
- Polyglutamine length-dependent toxicity from α1ACT in Drosophila models of spinocerebellar ataxia type 6
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.
- Ecdysone signaling induces two phases of cell cycle exit in Drosophila cells
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.
