Project description:We developed a ChIP protocol for the analysis of histone marks using less than 10,000 cells per IP, and used it to investigate the chromatin state of E11.5 mouse primordial germ cells (PGCs). A genome-wide ChIP-Seq analysis of E11.5 PGCs revealed a distribution of H3K4me3/H3K27me3 bivalent domains highly enriched for developmental regulatory genes. H3K4me3 and H3K27me3 ChIP-Seq from mouse E11.5 primordial germ cells.

Project description:Transcriptional profiling of individual mouse embryonic (e11.5) XY gonads comparing inbred strains that are sensitive (C57BL/6J) and resistant (129S1/SvImJ) to XY sex reversal, and their reciprocal F1 hybrids. Experiment Overall Design: Two-color Agilent microarray profiles of 20 individual pairs of e11.5 XY gonads, including 5- C57BL/6J, 5- 129S1/SvImJ, 5- (B6x129S1)F1, and 5- (129S1xB6)F1 samples. Within each strain, samples were collected from multiple litters to account for potential litter biases. All samples were processed following the same protocol.

Project description:We constructed a comparative proteome profile of female mouse fetal gonads at specific time points (11.5, 12.5, and 13.5 days post coitum), spanning a critical window for initiation of meiosis in female germ cells. We identified 3666 proteins, of which 473 were differentially expressed.
Project description:To elucidate the function of NANOS2 to regulate the transcriptome in embryonic male germ cells, we performed expression microarray analysis of the embyornic gonads of the Nanos2+/-, Nanos2-/- male and wild type female from E12.5 to E15.5. The Nanos2+/- and Nanos2-/- female gonads at E15.5 were analyzed as a negative control.
Project description:To investigate the role of the transcription factor AP-2 in craniofacial development, we performed: ATAC-seq on E11.5 craniofacial surface ectoderm in control and Tfap2a/Tfap2b ectoderm knock-out embryos; RNA-seq on E10.5 craniofacial prominences from control and Tfap2a/Tfap2b ectoderm knock-out embryos; histone-seq (H3K4me3) in E10.5 and E11.5 wild-type craniofacial surface ectoderm.
