ABSTRACT: ChIP-seq using anti-GFP antibody to map genomic binding of Prdm4-EGFP in stably transfected mouse embryonic stem cells Two independent ChIP-seq replicates for each of two independent Prdm4-EGFP expressing ES cell clones resulting in four anti-GFP ChIP-seq experiments. These samples have paired mouse IgG control.
Project description:The goal of this study was to profile Blimp1 binding in E18.5 small intestine using a Blimp-1-eGFP knock-in allele, and to compare Blimp-1-eGFP genomic binding with Irf-1 genomic binding in normal small intestine. Changes in Irf-1 binding between wild type and Prdm1/Blimp-1 mutant small intestine were also assessed. ChIP-seq was performed for Blimp-1-eGFP in duplicate in E18.5 small intestine expressing the fusion protein using anti-GFP antibody. As a negative control a single anti-GFP ChIP was also performed in wild type small intestine. ChIP-seq for Irf-1 was performed in duplicate in both wild type and Prdm1/Blimp-1 mutant E18.5 small intestine using an anti-Irf-1 antibody. Duplicate IgG ChIP control in wild types was performed as a negative control. All samples had an associated input chromatin sample sequenced.
Project description:To investigate location of Cajal bodies (CB) inside the cell nucleus, we created a stable cell line expressing the GFP version of CB-marker protein coilin at endogenous levels and performed ChIP-seq with anti-EGFP antibody. ChIP-seq revealed close association of CBs wih U3 genes, snRNA genes and histone genes in histone cluster 1 and 2. 1 biological replicate of coilin ChIP-seq and input sample
Project description:Translocation of ETS transcription factors including ERG and ETV1 occur in half of all prostate cancers. LNCaP cells harbor an ETV1 translocation. We performed ChIP-Seq analysis to determine the role of ETV1 on AR binding. The localization of enhancers were determined by H3K4me1 ChIP-Seq. To determine ETV1 and H3K4me1 localization, logarithmically growing cells
Project description:We previously mapped ETV1 using ChIP-Seq in GIST48 cells (GSE22441). Here, we map the enhancer landscape marked by histone H3K4me1 and the promoter landscape marked by histone H3K4me3 in GIST48 cells. Crosslink ChIP-Seq of H3K4me1 and H3K4me3 in GIST48 cells
Project description:This study describes the epigenetic profiling of Mll1 in mouse ES cells cultures in LIF/serum/feeder-free condition. ChIP-Seq profile of Mll1 was generated in E14Tg2a (E14) mESCs. A sequence profile of genomic DNA (Input) is also included.
Project description:Chromatin immunoprecipitation (ChIP) has been a cornerstone for epigenetic analyses over the last decades, but even coupled to sequencing approaches (ChIP-seq), it is ultimately limited to one protein at a time. In a complementary effort, we here combined ChIP with label-free quantitative (LFQ) mass spectrometry (ChIP-MS) to interrogate local chromatin compositions. We demonstrate the versality of our approach at telomeres, with transcription factors, in tissue and by dCas9-driven locus-specific enrichment.
Project description:The Otx2 homeobox transcription factor is essential for gastrulation and early neural development. We generated Otx2 conditional knockout (cKO) mice to investigate its roles in telencephalon development after E9.0. We conducted transcriptional profiling and in situ hybridization to identify genes de-regulated in Otx2 cKO ventral forebrain. In parallel, we used ChIP-seq to identify enhancer elements, OTX2 binding motif, and which de-regulated genes are likely direct targets of Otx2 transcriptional regulation. We found that Otx2 was essential in septum specification; regulation of Fgf signaling in the rostral telencephalon; and medial ganglionic eminence (MGE) patterning, neurogenesis, and oligodendrogenesis. Within the MGE, Otx2 was required for ventral but not dorsal identity; this is the first demonstration of a transcription factor that contributes to regional patterning within the MGE. Microdissected subpallium (septum, MGE, and LGE ) from wildtype E12.5 CD-1 embryos was used in three independentanti-OTX2 ChIP-seq experiments.
Project description:We overexpressed eGFP, eGFP-SPP and pmRFP-Q74 construct in HEK93 cells. We made immunoprecipitation of GFP. We compare the interactome of eGFP and eGFP-SPP.
Project description:Translocation of ETS transcription factors including ERG and ETV1 occur in half of all prostate cancers. We generated a mouse model of ERG ovexpression (Rosa26-ERG) which when crossed into prostate specific probasin-Cre, expressed ERG specifically in the prostate. We crossed Rosa26-ERG into Pten flox/flox allele to generate compound GEMM mouse. Here, we determined the genomic binding sites of ERG, AR, and the histone marks H3K4me1 and H3K4me3 that maps enhancers and promoters respectively in the prostates of these mice. The prostate of four six month old mice of each genotype were pooled. The chromatin was isolated and ChIP-Seq performed.
Project description:modENCODE_submission_4629 This submission comes from a modENCODE project of Michael Snyder. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We are identifying the DNA binding sites for 300 transcription factors in C. elegans. Each transcription factor gene is tagged with the same GFP fusion protein, permitting validation of the gene's correct spatio-temporal expression pattern in transgenic animals. Chromatin immunoprecipitation on each strain is peformed using an anti-GFP antibody, and any bound DNA is deep-sequenced using Solexa GA2 technology.
