Project description:This is an affymetrix array experiment comparing the transcriptome of the Malpighian tubule (or renal tubule) of 7-day adult Oregon R strain Drosophila melanogaster with matched whole fly samples. There are five tubule samples (each derived from approx 1000 tubules (!)), and 5 matched whole-fly samples. i.e. tubule 2 is dissected from the same vial as WholeFly2. As the tubule is probably the premier tissue for true physiology in Drosophila, the dataset can usefully be interrogated in conjunction with the detailed physiological understanding of the tissue: see http://fly.to/tubules
Project description:The experiment was designed to identify genes abundant or enriched in adult Drosophila melanogaster Malpighian (renal) tubule as compared to the whole fly.

Project description:We used RNA-seq to investigate gene expression variation in Malpighian tubules, which have a function analogous to that of human kidneys. In order to characterize population differentiation, we sequenced the Malpighian tubule transcriptomes of flies derived from two populations, one from sub-Saharan Africa (Zimbabwe) and one from Europe (the Netherlands). Males and females were examined separately. Overall, we found a high amount of differential expression between sexes (2,308 genes) and populations (2,474 genes). Although most of the differentially expressed genes were consistent between sexes and populations, there were 615 genes showed sex-biased expression in only one population and 557 genes showed population-biased expression in only one sex. mRNA expression profiles of Drosophila melanogaster Malpighian tubules from adult males and females from a European and an African population (2 biological replicates per sex and population)
Project description:We report the transcriptional profiles from individual Drosophila melanogaster (whole bodies or dissected brains) to Entomophthora muscae at 24 time points following fungal exposure. In whole fruit fly bodies, a significant immune response is observed following exposure to the fungus. In brains, few differences are consistently observed between infected and uninfected animals.
Project description:Transfer RNAs (tRNAs) are vital in determining the specificity of translation. Mutations in tRNAs can result in the mis-incorporation of amino acids into nascent polypeptides in a process known as mistranslation. Here, our goal was to test the impacts of different types of mistranslation in the model organism Drosophila melanogaster, as impact of mistranslation depends on the type of amino acid substitution. We created two fly lines - one expressing a serine tRNA variant with valine anticodon and the other with a serine tRNA variant with a threonine anticodon. Using mass spectrometry, we measure the amount of mistranslation at various points in fly development.
Project description:We used RNA-seq to investigate natural variation in gene expression in the Malpighian tubules of three inbred Drosophila melanogaster strains and their F1 hybrids. One of the strains was from a population in the species’ ancestral range (Zambia), while the other two were from a more recently derived population (Sweden).
