Project description:Separation of cell lineages during early mammalian development is required to establish the pluripotent founder cell population that will give rise to the embryo proper and a functional trophoblast to support its development. We systemically assessed the role of the homeobox gene Cdx2 in vivo and in vitro development with an RNAi approach. Effective elimination of both maternal and zygotic Cdx2 resulted in typical phenotypes of Cdx2-mutant embryos, such as failure of hatching and implantation. However, the blastulation and expression of TE specific markers in these Cdx2-deficient embryos excluded the possibility of Cdx2 to act as a TE determinant, although compromised structure and functioning of TE was observed and the resulted embryos were not viable. Strikingly, the efficiency of stem cell derivation was significantly higher than control when embryos were put on MEF at the 8-cell stage and the derived stem cells were fully pluripotent as shown by chimera and tetraploid complementation experiments. Comparative genomic hybridization of wild type and Cdx2 mutant at 8-cell and blastocyst mouse embryos were performed.

Project description:The object of this study was to identify genes transcriptionally upregulated and downregulated in response to Tcof1 haploin-sufficiency during mouse embryogensis Experiment Overall Design: Total RNA was extracted from 3 E8.5 wild-type and 3 E8.5 Tcof1+/- littermate embryos using the RNeasy Mini Protocol for Isolation of Total RNA from Animal Tissues (Qiagen) according to the manufacturerâs protocol. RNA quality and quantity was determined using the Bioanalyser. To generate targets for microarray analysis, total RNA (100 ng) from each wild-type and mutant embryo was amplified using Two-Cycle Target Labeling (Affymetrix) according to the manufacturerâs instructions. Biotinylated target cRNAs (20 μg) from the 3 wild-type and 3 Tcof1+/- embryos were hybridised to separate GeneChip® Mouse Genome 430 2.0 arrays (Affymetrix), following standard Affymetrix procedures.

Comparative genomic hybridization of wild type and Cdx2 mutant at 8-cell and blastocyst mouse embryos were performed. 8-cell biological duplicates and blastocyst stage biological triplicates embryos were used.The hybridization experiments were duplicated in a reciprocal labeling manner to reduce dye integration bias (dye-swaps).

Project description:A) Chromatins were prepared from Cdx2-inducible ES cells cultured for 48 - 60 hours in the Dox+ and Dox- conditions. Chromatin immunoprecipitation (ChIP) was carried out by using anti-FLAG M2 affinity gel. ChIP product was tested by Western blotting using anti-FLAG antibody. Nuclear extract from ES cells cultured for 48 - 60 hours in Dox+ and Dox- condition was used for the Western blot. B) CDX2 ChIP-Seq peaks in the Hoxa7 gene region. UCSC Mouse Mm9 browser view of Hoxa7 gene locus after mapping CDX2 ChIP-Seq tags locations in the wiggle format. CDX2 ChIP-Seq peaks are shown in red color. C) Cdx2 ChIP-Seq result was verified by qPCR. Target genes were indicated in (G). Primers flanking a promoter region of Hbb-b1 and Pou5f1 as well as a gene desert region in chromosome 3 were used as negative controls. Primers flanking of Actb gene promoter were used for normalization. The relative enrichment of CDX2 binding was indicated as fold change. (D) CDX2-binding motifs identified with CisFinder using 200 bp sequences centered at ChIP sites. (F) Potential CDX2-direct target genes based on ChIP-Seq and the alteration of expression by Cdx2-overexpression. (G) Identification of CDX2 target genes by combining information on binding sites with gene expression response to Cdx2 over-expression

MC1 ES cells were genetically modified for ROSA26 locus to have Tet-Off expression cassette for C-terminal FLAG tagged Cdx2. The peaks are obtained from the Eland Multi Alignment file. The number of tags in peaks was compared with the number of tags in the control sample for the same region corrected by the total coverage of tags. See supplemental file of the paper for details.
