Project description:Genetic variants in IRF5 are associated with multiple immune-mediated diseases. IRF5 has been predominantly focused on for its regulation of myeloid-derived cells. We found that IRF5 contributes to CD4+ T cell outcomes and that it regulates early T cell receptor-initiated signaling and subsequently translocates to the nucleus where it binds to promoters of various genes regulated with T cell activation. We report the chromatin state of freshly isolated and activated IRF5+/+ and IRF5-/- CD4+ T cells in vitro. While there are minimal differential peaks between freshly isolated IRF5+/+ and IRF5-/- CD4+ T cells, once activated multiple differential peaks are observed between IRF5+/+ and IRF5-/- CD4+ T cells.
Project description:We generated genome-wide chromatin state and RNA Polymerase II binding maps in mouse erythroid cells by ChIP-Seq. Examination of 4 different histone modifications (H3K4me3, H3K4me1, H3K27me3, H3K27ac) and RNA Polymerase II (RNAP2) binding in mouse erythroid cells (Ter119+).
Project description:We generated genome-wide H3K9me3-state maps of DP thymocytes purified from ESET+/+ and ESET-/- mice by using next generation sequencing. Examination of H3K9 trimethylation in DP thymocytes purified from ESET+/+ and ESET-/- mice.
Project description:We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone H3 trimethylation in rice endosperm. By obtaining about four hundred million bases of sequence from rice chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of rice endosperm. We find that the presence of H3K27me3 in either upstream or downstream of a gene is predominately associated with repression of the gene, while its absence is mainly associated with high gene expression. Examination of Histone H3 lysine 27 trimethylation in rice endosperm.
