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:A spectral library was built for Drosophila melanogaster. The spectral library allows reproducible quantification for thousands of peptides per SWATH-MS analysis.
Proteins from Drosophila melanogaster embryo, adult flies were digested with trypsin using in-gel digestion and the peptides were fractionated by high-pH reverse phase chromatography. HRM peptides were spiked into the peptides mixture and each fraction was injected on a Sciex TripleTOF 6600 mass spectrometer fitted with microflow set-up.
The resulting .wiff files were analysed using MaxQuant and Spectronaut.
Project description:Thermal acclimation study on Drosophila melanogaster reared at 3 different temperatures (12, 25, and 31oC). The proteomic profiles of D. melanogaster under these different temperatures were analyzed and compared using label-free tandem mass spectrometry.
Project description:To verify unannotated translated open reading frames (utORFs) identified from Drosophila melanogaster, we collected data to target them.
