Project description:Microarray technology was used to monitor the level of expression of 7,657 human genes in a set of 35 nodal peripheral T-cell lymphomas.
Project description:modENCODE_submission_2364 This submission comes from a modENCODE project of Jason Lieb. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: The focus of our analysis will be elements that specify nucleosome positioning and occupancy, control domains of gene expression, induce repression of the X chromosome, guide mitotic segregation and genome duplication, govern homolog pairing and recombination during meiosis, and organize chromosome positioning within the nucleus. 126 strategically selected targets include key histone modifications, histone variants, RNA polymerase II isoforms, dosage-compensation proteins, centromere components, homolog-pairing facilitators, recombination markers, and nuclear-envelope constituents. We will integrate information generated with existing knowledge on the biology of the targets, perform ChIP-chip analysis on mutant and RNAi extracts lacking selected target proteins, use extrachromosomal arrays to assess the ability of candidate identified sequence motifs to recruit targets in vivo, identify tissue-specific patterns of selected targets, and create integrated, quantitative models of transcription and whole-chromosome functions.

Project description:Genomic locations of Myc-tagged budding yeast Rif1 (including wilt-type and designer mutants) were analysed by ChIP-Seq. Mutants tested were rif1-7A and rif1-7E, in which Ser/Thr residues in the cluster of SQ/TQ sites were mutated to Ala or Glu, respectively. The performance of RIF1-9V5 was also tested.
Project description:Genomic locations of V5-tagged budding yeast Rif1 (including wilt-type and designer mutants) were analysed by ChIP-Seq. Mutants tested were rif1-7A and rif1-7E, in which Ser/Thr residues in the cluster of SQ/TQ sites were mutated to Ala or Glu, respectively. We also tested tested rif1-∆594, in which the C-terminal 594 amino acids were deleted.

Project description:A study to define the binding loci of RelA-containing NF-kappaB dimers in a human myometrial smooth muscle cell line after exposure to TNF. Monolayers of PHM1-31 cells were exposed to TNF (10ng/ml) for 1 hour or left unstimulated. The Chromatin immunoprecipitation (ChIP) assay was performed to recover RelA-bound chromatin or non-specifically bound chromatin with IgG. That chromatin was prepared and used to probe Affymetrix GeneChIP 1.0R Human Promoter arrays. Three biological replicates of each experiment were conducted. Datasets were subsequently analysed in Partek Genomics Suite V6.6 where baseline was normalised by subtraction of IgG values from conrresponding RelA-immunoprecipitated samples. Control samples immunoprecipitated with RelA were then compared with TNF-stimulated samples immunoprecipitated with RelA.
Project description:ChIP-seq for H3K27me3 and Ring1B was performed in WT mESCs and mESCs containing catalytically inactive Ring1B (I53A mutant). Cells expressing catalytically inactive Ring1B maintain the spatial distribution of Ring1B and H3K27me3 but at reduced levels. These findings support the notion that PRC2 recruitment is, in part, dependent on H2A ubiquitination (H2AK119ub). Two biological replicates were performed for Ring1B and H3K27me3 ChIPs in WT and Ring1B I53A/I53A mouse ESCs. Input chromatin was sequenced for each replicate as a control for ChIP enrichment.
