Project description:We report the nuclear Gcn5/α-KGDH complex plays vital role in histone H3 K79 succinylation. By obtaining over 731 million reads from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of histone H3 K79 succinylation, Gcn5, and α-KGDH in U251 cells.
Project description:CD4+CD25+FOXP3+ human regulatory T cells (Treg) are essential for self-tolerance and immune homeostasis. Here, we generated genome-wide maps of poised and active enhancer elements marked by histone H3 lysine 4 monomethylation and histone H3 lysine 27 acetylation for CD4+CD25highCD45RA+ naive and CD4+CD25highCD45RA- memory Treg and their CD25- conventional T cell (Tconv) counterparts after in vitro expansion . In addition we generated genome-wide maps of the transcription factors STAT5, FOXP3, RUNX1 and ETS1 in expanded CD4+CD25highCD45RA+ Treg- and CD4+CD25- Tconv to elucidate their role in cell type-specific gene regulation. ChIP-seq of 2 histone marks and transcription factors ETS1, STAT5, FOXP3 and RUNX1 in expanded T cell subpopulations
Project description:We investigated the genomic landscape of histone modifications in antigen-experienced CD8+ T cells. Using a ChIP-Seq approach coupled with global gene expression profiling [GSE67825], we generated genome-wide histone H3 lysine 4 (H3K4me3) and H3 lysine 27 (H3K27me3) trimethylation maps in distinct subsets of CD8+ T cells - naïve, stem cell memory, central memory, and effector memory. To gain insight into how histone architecture is remodeled during the differentiation of activated T cells

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.
Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
