The innate immune system is absolutely required for host defence, but, uncontrolled, it leads to inflammatory disease. This control is mediated, in part, by cytokines that are secreted by macrophages. Immune regulation is extraordinarily complex, and can be best investigated with systems approaches (that is, using computational tools to predict regulatory networks arising from global, high-throughput data sets). Here we use cluster analysis of a comprehensive set of transcriptomic data derived f ...[more]
Project description:Experiment evaluating aplicability of PlasTi-microarray for cross-species hybridization studies. PlasTi-microarray is a tiling oligonucleotide microarray originally designed for cucumber plastome analysis.Chloroplast RNA from Arabidopsis, tomato and spinach leaves was extracted, labelled and hybridized to PlasTi-microarray with the cucumber samples labelled with the second dye as a control. For each species, one biological sample and one technical replicate (labelled in a dye-swap orientation) were analyzed, resulting in two microarray hybridizations per species and six microarrays (a-f) in total.
Project description:Transcriptional profiling of head tissue of Drosophila Darkener of apricot (Doa) and found in neurons (fne) mutants was performed by RNA-SEQ in females and males. The transcriptional and post-transcriptional targets of these genes, which are involved in regulation by several processes including splicing and mRNA stability, are examined and compared to wild-type. Examination of mRNA profiles in heads of wild-type male and female adult flies are compared to mutant
Project description:Cellular signal transduction pathways modify gene expression programs in response to changes in the environment, but the mechanisms by which they regulate populations of genes under their control are not entirely understood. We present evidence that most mitogen-activated protein kinases and protein kinase A subunits become physically associated with the genes they regulate in the yeast genome. The ability to detect this interaction of signaling kinases with target genes can be used to map more precisely and comprehensively the regulatory circuitry that eukaryotic cells use to respond to their environment.
Project description:We explore the genome-wide occupancy of 4 different chromatin regulating complexes encoded in S. cerevisiae. We provide the data for histone acetyltransferases Gcn5 and Esa1 and histone deacetylases Hst1 and Rpd3/Sin3 under rich growth condition (YPD medium). We also include the occupancy data for RNA polymerase II under the same growth condition.
Project description:Using ChIP-Seq analysis we define genes induced in macrophages through transcriptional activation by STAT1 and search for the gain of function in mutant Stat1Y701F compared to the Stat1-/- mice.
Project description:Deep Sequencing of mRNA from the Drosophila melanogaster cell lines Kc167, CME_W1_Cl.8+, S2-DRSC and ML-DmBG3-c2. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf Analysis of poly(A)+ RNA from 2 biological replicates of Kc167, CME_W1_Cl.8+, S2-DRSC and ML-DmBG3-c2 cell lines.
Project description:Chromatin immunoprecipitation coupled with microarray analysis (ChIP-chip) was carried out to identify new target genes for ETS-domain transcription factor Elk-1. Experiment was done in Hela cells under serum starved conditions.
