Analysis of Drosophila melanogaster Chromosome Topology in Larval Eye and Antennal Discs

ABSTRACT: The goal of this study was to examine chromosome topology in Drosophila larval eye and antennal discs by identifying topologically associating domains (TADs) across the genome. TADs were compared between the eye and antennal disc to determine whether they contribute to cell-type-specific homologous pairing and transvection.

Analysis of Drosophila melanogaster Third Instar Larval Eye and Antennal Disc Transcriptomes

Project description:The goal of this study was to examine RNA expression levels in the Drosophila larval eye and antennal discs and determine whether higher levels of transcription were correlated with the ability of transgenes to drive pairing with their homologous endogenous loci between chromosomes. Additionally, RNA expression levels were compared between the eye and antennal discs to determine whether increased insulator protein expression contributed to increased pairing in the eye disc.

RNA-seq in wild-type and glass mutant eye-antennal discs in Drosophila melanogaster

Project description:The aim of this data set is to perform a differential expression analysis between wild type eye-antennal imaginal disc and discs that are homozygous glass mutant gl[60j]. This data set is used to validate Glass target gene predictions identified by i-cisTarget on a set of conserved eye-specific genes. RNA-seq was performed in eye-antennal imaginal discs of two D.melanogaster wild-type strains (Canton S and strain RAL-208 (Jordan et al. 2007, Ayroles et al. 2009)), representing two biological replicates; and in glass mutant (gl[60j]) discs for two technical replicates.

Tag-seq in eye-antennal and wing imaginal discs of D.melanogaster, D.yakuba, and D.virilis; RNA-seq in wild-type and glass mutant D.melanogaster eye-antennal imaginal discs.

Project description:In this study we use Tag-sequencing in eye-antennal and wing imaginal discs across Drosophila species to determine a set of conserved eye-specific developmental genes. Next, we perform motif discovery analysis using the tool i-cisTarget, to depict the core gene developmental network underlying compound eye photoreceptor. The Glass position weight matrix appears as the most highly overrepresented motif, thus positioning Glass as a master regulator in compound eye photoreceptor development. Differential gene expression analysis by RNA-seq in D.melanogaster wild-type eye-antennal versus glass mutant [gl 60j] shows that the majority of our predicted Glass targets show strong downregulation in the glass mutant. This SuperSeries is composed of the following subset Series: GSE39781: RNA-seq in wild-type and glass mutant eye-antennal discs in Drosophila melanogaster GSE39782: Tag-seq profiling in eye-antennal and wing imaginal discs of D. melanogaster, D. yakuba and D. virilis

Expression data from eye antennal imaginal disc expressing either activated Ras or secreted Spitz

Project description:We have used microarrays to identify genes expressed and required for the second mitotic wave (SMW) during eye development. Eye discs expressing Spitz under the control of GMR Gal4 have no SMW as Spitz promotes G1 arrest, ectopic differentiation also occures. To control for the ectopic differentiation, Spi expressing eye antennal discs were compared to eye antennal discs expressing activated RasV12. In discs expresseding RasV12 under the control of GMRGal4 the SMW takes place normally prior to any ectopic differentiation. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes during this process. Keywords: Comparison of eye antennal discs of two different over expression genotypes

Atonal and Senseless perturbations in Drosophila melanogaster eye-antennal imaginal discs.

Project description:The goal of this study is to identify co-expressed genes downstream of Atonal and Senseless. These gene lists are used as candidate target genes (technically: as foreground sets) in computational predictions of cis-regulatory elements using the cisTargetX method (http://med.kuleuven.be/cme-mg/lng/cisTargetX). Together, the gene expression results and cis-regulatory predictions, yield a gene regulatory network underlying the early events in retinal differentiation. Predicted cis-regulatory interactions have been validated extensively in vivo using enhancer reporter assays and genetic perturbations. Six samples were analyzed for Atonal gain-of-function (GOF) in the eye-antennal imaginal discs of third instar larvae of Drosophila melanogaster, namely three biological repeats for two different Gal4 drivers (Gal4/7 and AtoGal), crossed with UASato. Three samples were analyzed for Atonal loss-of-function (LOF) in the eye-antennal imaginal discs, namely three biological repeats of ato-/- larvae. Three samples were analyzed for Senseless GOF, namely three biological repeats of atoGal4 crossed with UASsens. Finally, eight control samples were analyzed, namely two biological repeats of four different lines (atoGal4, Gal4/7, UASato, and cantonS wild type).

Expression data from L3 Drosophila antennal-eyediscs

Project description:Growth of the drosophila eye imaginal discs is controlled by the activation of Notch in the dorsal-ventral boundary. Overexpression in the eye disc of the Notch ligand Delta together with lola and pipsqueak from the GS(2)88A8 line induces tumoral growth. We used microarray to analyze the expression profile of tumoral discs. Antennal-eye discs of Drosophila L3 larvae were selected for RNA extraction and hybridization on Affymetrix microarrayas. Two genetic conditions were analyzed: tumoral eye discs (ey-Gal4 GS(2)88A8 UAS-Dl) and control eye discs (GS(2)88A8 UAS-Dl). Three different biological replicates of each condition, each one consisting on 300 hundred pairs of eye discs, were analyzed.
