Project description:Chromatin accessibility mapping by DNase-seq on whole embryo and FACS-isolated cell populations during Drosophila melanogaster embryogenesis at 2-4 hrs, 4-6 hrs, 6-8 hrs, 8-10 hrs and 10-12 hrs after egg-laying. Note that the two 8 bases long UMIs clipped from read1 and read2 are present in the FastQ file header (followed by the 8 bp long invariant sample barcode)

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.
Project description:DNase-seq over 2 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 NextSeq. This Study is an extension to the previously published Study E-MTAB-3797.
Project description:Drosophila melanogaster is a well-studied genetic model organism with several large-scale transcriptome resources. Here we investigate 7,952 proteins during the fly life cycle from embryo to adult and also provide a high-resolution temporal time course proteome of 5,458 proteins during embryogenesis. We use our large scale data set to compare transcript/protein expression, uncovering examples of extreme differences between mRNA and protein abundance. In the embryogenesis proteome, the time delay in protein synthesis after transcript expression was determined. For some proteins, including the transcription factor lola, we monitor isoform specific expression levels during early fly development. Furthermore, we obtained firm evidence of 268 small proteins, which are hard to predict by bioinformatics. We observe peptides originating from non-coding regions of the genome and identified Cyp9f3psi as a protein-coding gene. As a powerful resource to the community, we additionally created an interactive web interface (http://www.butterlab.org) advancing the access to our data.
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.
