Project description:To probe how Brachyury regulates its target genes, we performed mRNA-seq to analyze gene expression changes after Brachyury depletion by the lentivirus-mediated shRNA WT and Brachytury Knockdown embryoid bodies were collected at EB day 4. Subsequently, mRNA-seq expriments were performed with whole embryoid bodies

Project description:To identify Brachyury target genes in vivo and elucidate how Brachyury-mediated regulation contributes to early mouse developmental homeostasis and coordination, we performed mRNA-seq to compare gene expression profiles of WT and Tc/Tc embryos at both E7.5 ~ 8.0 and E10.0 ~ 10.5

Project description:Brachyury (or T) is expressed in the primitive streak, tailbud and notochord of the early mouse embryo (Herrmann et al., 1990; Wilkinson et al., 1990). It plays a key role in early development: mouse embryos lacking functional Brachyury protein fail to gastrulate properly, do not form a differentiated notochord, and lack structures posterior to somite seven (Chesley, 1935; Dobrovolskaïa-Zavadskaïa, 1927; Naiche et al., 2005; Wilson et al., 1995; Wilson et al., 1993; Yanagisawa et al., 1981) We apply a ChIP-on-chip approach to identify targets of Brachyury during mouse ES cell differentiation. ES cells provide an abundant source of differentiating cells and the identification of Brachyury targets in such cells will shed light on the mechanisms of ES cell differentiation and, by analyzing the targets in the developing embryo, will reveal to what extent they provide a bone fide model of early mouse development.

Project description:shRNA-mediated brachyury knockdown was performed on the chordoma cell line U-CH1 as replicates. RNA was extracted, labelled and hybridised to Human Gene 1.0ST chips followed by gene expression microarray analysis.This was followed by a ChIP-seq experiment using a specific brachyury antibody, the data for which are stored in Raw ChIP-seq reads are stored under: European Nucleotide Archive accession ERP000953 and Array Express accession E-ERAD-23.

Project description:This experiment is part of the FunGenES project (FunGenES - Functional Genomics in Embryonic Stem Cells partially funded by the 6th Framework Programme of the European Union, http://www.fungenes.org). The experiment was conducted at University of Cologne, Cologne, Germany. Goal of the experiment was an analysis the transcriptome of the ES-cell derived pure T-brachyury expressing CGR8 cells. Materials and methods: On day 0, EBs were made from T-brachyury ES (CGR8) cell line by hanging drop protocol. On second day, the hanging drop EBs were transferred into suspension. On third day, the EBs were treated or untreated with puromycin at a concentration of 5ug/ml for 2 days. On 5th day, the medium was changed and added medium with or without puromycin at a concentration of 2 ug/ml for 1 day. On day 6th , RNA was isolated from EBs treated or untreated with puromycin for affymetrix analysis.

Project description:To gain new mechanistic insights into highly-regulated lineage specification and morphogenetic processes during early embryogenesis, we applied ChIP-seq to identify transcriptional programs mediated by a key developmental regulator - Brachyury. Embryonic stem cells were differentiated into Brachyury-positive mesoendoderm cells. And, ChIP-seq experiments were carried out by two independent Brachyury antibodies.

Project description:Mapping ultra high resolution of Brachyury:DNA interaction would provide us with valuable new mechanistic insights into complex molecular transactions at Brachyury-bound enhancers. Embryonic stem cells were differentiated into Brachyury-positive mesoendoderm cells. And, ChIP-exo experiment was then performed to identify detailed Brachyury-DNA binding profiles.
