Project description:We describe here the genome-wide binding sites of Cyclin G in Drosophila melanogaster wing imaginal discs from third instar female larvae. We used a transgenic line expressing a version Cyclin G deleted of the PEST domain (the 25 COOH-terminal amin-acids) and tagged by Myc under the control of the daugterless-Gal4 ubiquitous driver.

Project description:We performed a genome-wide ChIP analysis to find the set of target genes regulated by Cbt in Drosophila wing imaginal discs. We reported multiple transcriptional regulators and genes involved in the developlment, growth and patterning of the fruit fly.

Project description:We mapped open chromatin by FAIRE-seq and measured gene expression by RNA-seq in 3 types of Drosophila samples: staged whole embryos, imaginal discs, pharate appendages. We first demonstrate that regions of open chromatin precisely define regions of enhancer activity in developing embryos. In contrast to the dynamic changes in open chromatin observed between different stages of embryogenesis, we found that the open chromatin profiles in wing, leg, and haltere imaginal discs are nearly identical. This was also true again later in development, where the adult appendages also share nearly identical open chromatin profiles. Therefore, at a given developmental time point, different appendages are specified using a shared set of DNA regulatory elements. However, from one time point to the next, the set of accessible regulatory elements changes. Open chromatin profiles in appendage imaginal discs are almost entirely different than those of the adult appendages. We propose that master regulator transcription factors create morphologically distinct structures by differentially influencing the function of the same set of DNA regulatory modules. Open chromatin profiling during Drosophila development: 3 stages of embryogenesis (2-replicates each); wing, leg, and haltere 3rd instar imaginal discs (3-replicates each); 3rd larval central nervous system (2-replicates); eye-antennal imaginal discs (2-replicates); wing, leg, and haltere pharate appendages (2-replicates each); Genomic DNA Inputs. Sequencing performed on Illumina GAII and HiSeq.

Project description:In order to analyze the global changes in gene expression resulting from induction of NetA-Fra signaling, we carried out a microarray experiment comparing Drosophila third instar wing imaginal discs in which Net+Fra had been overexpressed to age matched wild type wing imaginal discs. RNA extracted from both +NetA-Fra overexpression and wildtype third instar imaginal discs were hybridized to the Affymetrix GeneChip Drosophila Genome 2.0 .

Project description:The systemic response to injury in Drosophila melanogaster is characterized by the activation of specific signaling pathways that facilitate the regeneration of wounded tissue and help coordinate wound healing with organism growth. The mechanisms by which damaged tissues influence the development and function of peripheral non-injured tissues is not fully understood. Injury was induced in early third instar larvae via temperature-dependent cell death in wing imaginal discs. Microarray analysis using RNA isolated from injured and control was used to identify genes underlying the systemic injury response. We identified 150 genes which were differentially expressed in response to localized cell death in wing imaginal discs. Upregulated genes were associated biological processes including carnitine biosynthesis, signal transduction and regulation of oxidoreductase activity while terms associated with downregulated genes included wound healing, imaginal disc-derived wing hair outgrowth, and regulation of glutamatergic synaptic transmission. Pathway analysis revealed that wing disc damage led to changes in fatty acid, cysteine, and carnitine metabolism. One gene, 14-3-3ζ, which encodes a known regulator of Ras/MAPK signaling was identified as a potential regulator of transdetermination during tissue regeneration. Our results raise the possibility that immune function and cell proliferation during wing disc repair and regeneration in Drosophila may require the sulfur amino acid cysteine and its’ metabolites, taurine and glutathione, similar to what has been reported during tissue repair in mammals. Further, it seems likely that imaginal disc damage stimulates the mobilization of fatty acids to support the energetically demanding process of tissue regeneration. The roles of additional genes that are differentially regulated following imaginal disc injury remain to be elucidated.

Project description:In order to analyze the global changes in gene expression resulting from induction of NetA-Fra signaling, we carried out a microarray experiment comparing Drosophila third instar wing imaginal discs in which Net+Fra had been overexpressed to age matched wild type wing imaginal discs. RNA extracted from both +NetA-Fra overexpression and wildtype third instar imaginal discs were hybridized to the Affymetrix GeneChip Drosophila Genome 2.0 . Heat shock induced GFP-marked clones ectopically expressing NetA+Fra in larvae were generated. Controls for this study included age matched wildtype third instar wing imaginal discs bearing GFP clones which were prepared in the same manner. Total RNA was extracted from dissected +NetA-Fra vs. control third instar wing imaginal discs and hybridized to the Affymetrix GeneChip Drosophila Genome 2.0.
