Project description:We recently reported that an orthologue of STING regulates infection by picorna-like viruses in drosophila. Here, we show that injection of flies with 2’3’-cGAMP can induce expression of dSTING-regulated genes. Analysis of the transcriptome of 2’3’-cGAMP injected flies reveals a complex pattern of response, with early and late induced genes. Our results reveal that dSTING regulates an NF-κB -dependent antiviral program, which predates the emergence of Interferon Regulatory Factors and interferons in vertebrates.
Project description:dG9a-depletion decreases the starvation resistance in the adult stage of Drosophila melanogaster. To determine which genes are regulated by dG9a under starvation stress, we examined mRNA levels by performing RNA-sequence analysis using 0 h and 12 h starved dG9a null mutant and wild type as a control.
Project description:dFOXO targets in adult Drosophila melanogaster females, and the effect of insulin signalling and stress on binding. The experimets determined the binding locations of dFOXO in the whole adult female fly using ChIP-chip. The protocol was validated using mock conditions: pre-immune serum or IP on chromatin from foxo null flies. The response of this binding to stress induced by treatment of flies with paraquat or by their exposure to starvation, as well as the response to an insulin-signalling-reducing genetic manipulation (over-expression of dominant negative form of the insulin receptor), was determined.
