Project description:Expression data in dSTING knockdown S2 cells and whole flies after mock or pathogenic infection
Project description:Parental flies (y1v1;P{TRiP.JF01138}attP2 and y1w*;P{Act5C-GAL4}25FO1/CyO,y+) were mated to obtain progeny with genotypes for ubiquitous DmSTING RNAi and sibling controls. 2-7 day old flies were used for all infections. 23 nl of listeria monocytogenes (strain 10403S) at 1e7 CFU/ml was injected intrathoracically. Mock inoculation was performed with PBS. Whole flies were homogenized 24 h post-infection.
Project description:A method for the long-term maintenance of germ-free flies was established using aseptic isolators. The methodology effectively and reliably yields large numbers of germ-free flies in homogeneous cultures. Germ-free flies exhibited increased lifespan (only female flies) and decreased egg production, markedly reduced fat storage, less midday sleep, and enhanced aggressiveness (male flies). Fructilactobacillus—a species of fly intestinal microbes—was re-colonized in germ-free flies, and these gnotobiotic flies were successfully maintained for numerous generations. The proteome of those flies were analyzed.
Project description:Expression data from Drosophila melanogaster adults which contain transgenes to deliver a knockdown effect of Dhr96 expression, or over-expression of Dhr96, compared to control flies.
Project description:Hypoxia plays a key pathogenic role in the outcome of many pathologic conditions. To elucidate how organisms successfully adapt to hypoxia, a population of Drosophila melanogaster was generated, through an iterative selection process, that is able to complete its lifecycle at 4% O2, a level lethal to the starting parental population. Transcriptomic analysis of flies adapted for >200 generations was performed to identify pathways and processes that contribute to the adapted phenotype, comparing gene expression of three developmental stages with generation-matched control flies. A third group was included, hypoxia-adapted flies reverted to 21% O2 for five generations, to address the relative contributions of genetics and hypoxic environment to the gene expression differences. We identified the largest number of expression differences in 0.5-3 hr post-eclosion adult flies that were hypoxia-adapted and maintained in 4% O2, and found evidence that changes in Wnt signaling contribute to hypoxia tolerance in flies.

A population of flies able to complete their life cycle at 4% O2 was selected from a starting population of 27 isogenic D. melanogaster lines exposed to increasingly lower O2 levels over many generations. Transcriptomic analysis of adapted flies maintained at 4% O2 or reverted to room air for five generations, and of generation matched naive controls, was performed to better understand changes in gene expression in adapted flies and to investigate the relative contributions of genetics versus environment to these differences.
