Project description:Drosophila tdf, another name apontic (apt), encodes a bZIP transcription factor that is required for the development of trachea, heart, head and neural system. However, little is known about the target of TDF/Apt. To identify theTDF/ Apt regulated genes, we compared expression profiles of mRNA purified from wild-type and tdf mutant embryos. Summary file is emtdf-yw.CHP.

Summary file is emtdf-yw.CHP. yw and tdf mutant embryos were selected at later stage of development for RNA extraction and hybridization on Affymetrix microarrays. We identified tdf mutant embryos using CyOact-GFP balancer chromosome.
Project description:To explore the effect of IDO-APT on T cell function, we conducted RNA transcriptome profiling of NPs, named as NP-Scr-APT in article, and NP-IDO-APT treated lymphocytes.
Project description:Quantitative mass spectrometry-based proteomic analyses in combination with genetics provide powerful tools in developmental cell signaling research. Drosophila melanogaster is one of the most widely used genetic models for studying development and disease. Here we combined quantitative proteomics with genetic selection to determine global changes in the proteome upon depletion of the Heartless (Htl) Fibroblast-Growth Factor (FGF) receptor signaling in Drosophila embryos at the gastrula stage. We present a robust, single generation SILAC (stable isotope labeling with amino acids in cell culture) protocol for labeling proteins in early embryos and for the selection of homozygously mutant embryos at pre-gastrula stages using an independent genetic marker. Our analyses detected quantitative changes in the global proteome of htl mutant embryos during gastrulation. We identified distinct classes of down-regulated and up-regulated proteins and network analyses indicates functionally related groups of proteins in each class. In addition, we identified changes in the abundance of phosphopeptides. These data suggest that FGF signaling in the early embryo affects global changes in the abundance of metabolic, nucleoplasmic, cytoskeletal and transport proteins.
