Identification of factors involved in JAK/STAT-dependent cell competition

ABSTRACT: We report the transcriptional profiles obtained by next-generation sequencing (NGS) of FACS-purified cells from the dpp-domain of wing imaginal discs from mid-third instar Drosophila melanogaster larvae. The goals of this study are to compare NGS-derived transcriptome profiling (RNA-seq) of dpp-domain cells that have elevated JAK/STAT signaling or elevated Myc expression compared to control cells.

JAK/STAT coordinates cell proliferation during disc regeneration with Dilp8-mediated developmental delay in Drosophila melanogaster

Project description:Regeneration of fragmented Drosophila imaginal discs occurs in an epimorphic manner, involving local cell proliferation at the wound site. Following disc fragmentation, cells at the wound site activate a restoration program through wound healing, regenerative cell proliferation and repatterning of the tissue. However, the interplay of signaling cascades, driving these early reprogramming steps, is not well understood. Here we profiled the transcriptome of regenerating cells in the early phase within twenty-four hours after wounding. We found that JAK/STAT signaling becomes activated at the wound site and promotes regenerative cell proliferation in cooperation with Wingless (Wg) signaling. In addition, we demonstrated that the expression of Drosophila insulin-like peptide 8 (dilp8), which encodes a paracrine peptide to delay the onset of pupariation, is controlled by JAK/STAT signaling in early regenerating discs. Our findings suggest that JAK/STAT signaling plays a pivotal role in coordinating regenerative disc growth with organismal developmental timing. In order to analyze transcriptome change in early regenerating imaginal disc, Drosophila prothorasic leg discs were fragmented (to anterior one-quarter or posterior three-quarters) and cultured ex vivo in adult fly abdomen. Regenerating cells in early regeneration phase (at 12 or 24 hours after wounding) were subjected to transcriptome profiling with Affymetrix microarrays. For control samples, the corresponding regions of uncut-cultured discs and uncut-uncultured discs were used.

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 . 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.

Project description:We report here the transcriptomic analysis of Drosophila melanogaster wing imaginal discs from third instar female larvae expressing Cyclin G deleted of the PEST domain (the 25 COOH-terminal amin-acids) under the control of the daugterless-Gal4 ubiquitous driver. The negative control was transgenic flies wearing only the daugterless-Gal4 driver.

Brinker regulates wing disc growth in part via repression of Myc expression

Project description:The molecular mechanisms regulating tissue size represent an unsolved puzzle in developmental biology. One signaling pathway controlling growth of the Drosophila wing is Dpp. Dpp promotes growth via repression of the transcription factor Brinker. The transcriptional targets of Brinker that control cell growth and proliferation, however, are not yet fully elucidated. We report here a genome-wide ChIP-seq of endogenous Brinker from wing imaginal discs. We identify the growth regulator Myc as a target of Brinker and show that Myc together with the microRNA bantam explain a large fraction of the growth inhibition caused by Brinker. This work sheds light on the effector mechanisms by which Dpp signaling controls tissue growth. Identification of Brinker binding sites in Wing imaginal discs cells
