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:Promoter proximal pausing (PPP) of RNA Polymerase II has emerged as a crucial rate-limiting-step in the regulation of gene expression. Regulation of PPP is brought about by complexes 7SK snRNP, P-TEFb (Cdk9/cycT) and the Negative Elongation Factor (NELF) which are highly conserved from Drosophila to humans. Here we show that RNAi-mediated depletion of bin3 or Hexim of the 7SK snRNP complex or depletion of individual components of the NELF complex enhance Yki-driven growth leading to neoplastic transformation of Drosophila wing imaginal discs. We also show that increased CDK9 expression cooperates with Yki, in driving neoplastic growth. Interestingly, over-expression of CDK9 on its own or in the background of depletion of one of the components of 7SK snRNP or the NELF complex necessarily and specifically needed Yki over-expression to cause tumorous growth. Genome-wide gene expression analyses suggested that deregulation of protein homeostasis is associated with tumorous growth of wing imaginal discs. As both Fat/Hippo/Yki pathway and PPP are highly conserved, our observations may provide insights into mechanisms of oncogenic function of YAP, the orthologue of Yki in human.
