Project description:The miRNA 310-311-312-313 cluster from D. melanogaster (referred to as Dm310s) and the homolog from D. pseudoobscura (Dp310s) were used to transform D. melanogaster. The over-expression of UAS-miR310s in two Dm310s transgenic lines (M1-7 and M1-3) and Dp310s transgenic line P4-18 was driven by GAL4 line NP5941 with native miR-310 expression pattern. We used Drosophila Tiling 1.0 F arrays to assess the effects of miR310s over-expression on the whole transcriptome.
Project description:In this study we use a combination of proteomics Label-Free quantification methods to monitor protein expression changes over a time course of more than 20 hours of embryo development in Drosophila melanogaster.
Project description:STING is a protein that plays important role in innate immune response. However, it also has functions not related to immunity. We studied role of STING in fruit fly Drosophila melanogaster. We used microarray to detect gene expression changes in dSTING knockout fruit flies. We studied role of STING in fruit fly Drosophila melanogaster. To detect gene expression changes in dSTING-knockout flies microarray assay was used.
Project description:We tested and measured the strength of heterospecific interactions between microRNAs and their targets by carrying out transgenic experiments across Drosophila species, by over-expressing the miR310s cluster of D. melanogaster (Dm310s) and D. pseudoobscura (Dp310s) in D. melanogaster. A knockout line, referred to as Dm310s (−), was also included for comparison. The whole-genome expression (WGE) of the Dp310s and Dm310s transgenic lines were compared on two platforms of both Affymetrix tiling array and DGRC cDNA array. The WGE of knockout line was assayed on only Affymetrix tiling array. In the Dm310s lines, overexpression was more common than underexpression among misregulated genes while the pattern appeared to be reversed in the Dm310s(−) line. The number of genes significantly misexpressed under the influence of Dp310s is 3-10 times greater than under Dm310s. Importantly, the numbers of predicted targets are similar between them. Expression analysis of the predicted target genes suggests that miRNAs may sometimes function to buffer fluctuations in the transcriptome output. After the buffering function has evolved, heterospecific combinations may cause adverse effects. This SuperSeries is composed of the SubSeries listed below.

We used Drosophila Tiling 1.0 F arrays to assess the effects of miR310s over-expression on the whole transcriptome. We compared the transcriptional profiling of Dm310s and Dp310s overexpression in D.melanogaster using double-stranded cDNA followed by bioprime random labeling, and hybridization to Affy Drosophila tiling 1.0 F array. Third-instar progeny larvae from the crosses with maternal NP5941 and paternal UAS-miR-310 cluster transgenic lines were collected and third-instar larvae from the cross with maternal NP5941 and paternal w1118 were used as control. Three biological repeats were used for each stock. A processed data matrix reporting values (log2 intensity after quantile normalization) for all of the Samples is linked below as a supplementary file.
Project description:DNase-seq over 3 matching developmental time points in Drosophila melanogaster and Drosophila virilis embryos was performed. The aim is to assess conservation of hypersensitive regions between two distantly related species. Samples were sequenced using Illumina HiSeq.
