Project description:The transcription cofactor Yki drives growth and proliferation in part by controlling mitochondrial network formation. To determine if Yki and Sd are directly bound to DNA corresponding to mitochondrial genes, we used chromatin immunoprecipitation and whole genome tiling arrays (ChIP-chip) to identify regions bound by these factors in eye-antenna and wing imaginal discs. The supplementary .bed files contain all Yki or Sd binding sites (called at 5% FDR) in wing or eye-antenna imaginal discs, as well as shared Sd+Yki sites and associated target genes. Wing or eye-antenna imaginal discs ChIPped for Yki or Sd-GFP vs. input DNA from corresponding imaginal discs.

Project description:In order to study how ectopic Yki drives tissue overgrowth in Drosophila imaginal discs, we overexpressed the constitutively active Yki3SA and deleted wts in clones of cells in the entire eye-antennal imaginal disc, as well as specifically in eye disc proper cells using Optix-Gal4. Using the MARCM system allowed us to compare the effects of Yki3SA overexpression in wild-type and sd mutant clones.

Project description:Throughout Metazoa, developmental processes are controlled by a surprisingly limited number of conserved signaling pathways. Precisely how these signaling cassettes were assembled in early animal evolution remains poorly understood, as do the molecular transitions that potentiated the acquisition of their myriad developmental functions. Here we analyze the molecular evolution of the proto-oncogene YAP/Yorkie, a key effector of the Hippo signaling pathway that controls organ size in both Drosophila and mammals. Based on heterologous functional analysis of evolutionarily distant Yap/Yorkie orthologs, we demonstrate that a structurally distinct interaction interface between Yap/Yorkie and its partner TEAD/Scalloped became fixed in the eumetazoan common ancestor. We then combine transcriptional profiling of tissues expressing phylogenetically diverse forms of Yap/Yorkie with ChIP-seq validation in order to identify a common downstream gene expression program underlying the control of tissue growth in Drosophila. Intriguingly, a subset of the newly-identified Yorkie target genes are also induced by Yap in mammalian tissues, thus revealing a conserved Yap-dependent gene expression signature likely to mediate organ size control throughout bilaterian animals. Combined, these experiments provide new mechanistic insights while revealing the ancient evolutionary history of Hippo signaling. We sought to define the downstream target genes of selected Yap variants by performing RNA sequencing analysis (RNA-seq) on total RNA isolated from GMR-Gal4>Yap eye discs. Transcriptional profiles were generated in triplicate from eye imaginal disks with either endogenous Yki, or GMR-Gal4 over-expressed Yki, Trichoplax Yap, Monosiga Yap, or Monisiga Yap+TEAD domain, using deep sequencing via Illumina Hi Seq.

We sought to determine Yki and Sd target genes in Drosophila by immunoprecipitation of Yki, sd and RNA polymerase II. Chromatin immunoprecipitation of Yki, sd, and RNA polymerase II from eye disks was performed.
