Project description:We investigated tissue-specific regulation of gene expression in a long lived Drosophila IIS mutant (dilp2-3,5) compared to its control (wDah). As in the majority of Drosophila laboratory strains, the endosymbiont Wolbachia was present; in the absence of Wolbachia, life extension through dilp2-3,5 is abrogated (Grönke et al. 2010). To control for this, we additionally included strains of the same genotypes that lacked Wolbachia (dilp2-3,5T, wDahT). We quantified gene expression concurrently on the level of the proteome and the transcriptome, in four key tissues: brain, gut, fat body, and muscle. Proteome quantification was carried out on five biological replicates per experimental group. Corresponding transcriptome quantification was carried out on three biological replicates per experimental group, and published on GEO (accession number *GSE122190*)
