Project description:Analysis of third instar eye-antennal Drosophila imaginal discs with forced expression of hth, tsh or hth+tsh in the eye using an eye-specific GAL4 driver (optix2.3-GAL4). Forced maintenance of hth+tsh expression (but not of any of the two alone) results in overgrowth and aberrant cell differentiation. Results provide insight into new targets of hth+tsh.

D. melanogaster eye-antennal imaginal discs developmental transcriptome

Project description:Transcriptomes of Drosophila melanogaster eye-antennal imaginal discs at three sequential larval stages: late 2nd instar (72h after egg laying (AEL)), mid 3rd instar (96h AEL) and late 3rd instar (120h AEL).

Evolutionary changes in cis regulation are associated with altered chromatin activity and gene expression levels in the Drosophila eye development (RNA-Seq)

Project description:Expression profiling by high-throughput sequencing (RNA-seq) across eight WT Drosophila species - D. melanogaster, D. simulans, D. yakuba, D. ananassae, D. pseudoobscura, D. willistoni, D. mojavensis and D. virilis - and three tissues, namely, brain, eye-antennal and imaginal discs, at the stage of third instar larvae.

Gene expression data comparing rbf1 mutant and PSC overexpressing Drosophila eye imaginal discs

Project description:PSC overexpression can cause phenotypes specifically in an rbf1 mutant background, likely due to a sensitization to PSC-induced phenotypes. The goal of this study is to understand the interaction between rbf1 hypomorphic mutation and the overexpression of Polycomb group gene Posterior sex combs. We used Drosophila larval eye imaginal discs that were mutant for rbf1 or overexpressing PSC and compared these to control larval eye discs to assess changes in gene expression. We identified a common set of genes that are deregulated when rbf1 is mutated or when PSC is overexpressed. RNA was extracted from eye imaginal discs dissected from third instar Drosophila larvae. Samples were amplified and hybridized to Affymetrix Drosophila Genome 2.0 Array. To better understand the effects of rbf1 mutation and PSC overexpression, we compared the gene expression of rbf1 mutant eye discs and eye discs overexpressing PSC to control eye discs.

Gene expression profile of Drosophila third instar larval wing imaginal discs overexpressing netrinA (netA) and frazzled (fra).

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 .
