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

ABSTRACT: 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.

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

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).

Chromatine immunoprecipation of atonal binding sites in Drosophila L3 eye imaginal discs

Project description:Atonal is a proneural transcription factor expressed in the Drosophila eye imaginal discs. To characterize the putative targes of Atonal in the eye discs we have used an endogenously GFP-tagged version of atonal to immunoprecipate disc samples with anti-GFP antibodies

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).

DamID profiling of proneural transcription factor binding in Drosophila melanogaster wing imaginal discs

Project description:Genome-wide identification of the binding sites of the Drosophila transcription factors Achaete, Asense, E(spl)m3-HLH and Senseless in wing imaginal cells using DamID profiling. Each Dam-fusion-derived sample is compared to a control Dam-only sample. Two biological replicates were performed for sca-Asense, neur-Asense, sca-Achaete, neur-Achaete, neur-Sens and sca-E(spl)m3-HLH.

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 SubSeries listed below.
