Project description:Bone marrow-derived multipotent stromal cells (BM-MSCs) exhibit therapuetically valuable properties, including the capacity to differentiate into skeletal tissues and modulate immune system activity. These properties depend on proper regulation of dynamic gene expression in response to environmental and developmental stimuli. This study used chromatin immunoprecipitation (ChIP) coupled with human promoter tiling microarray analysis (ChIP-on-chip) to profile histones H3K4me3 and H3K27me3 at promoters genome-wide. The goal of the study was to identify gene promoters marked by H3K27me3 and H3K4me3 in BM-MSCs. ChIP-on-chip performed with antibodies to H3K4me3 and H3K27me3 on BM-MSCs from 3 different donors (labeled 1632, 167696, and 8F3560) and with technical replicates.

Project description:This study describes the epigenetic profiling of the X chromosome during X inactivation. It includes H3K4me3 and H3K27me3 ChIP-Seq profiles of male (E14) and female (LF2 and XT67E1) mouse ES cells, together with their differentiated derivatives (either 4d atRA or 10d EB). It also includes ChIP-chip profiles around the Xic on chromosome X of H3K4me3, H3K27me3, H3K9me2, H3K36me3, Pol II, TBP, H3-Core as well as expression, using male (E14) and female (LF2) mouse ES cells, together with their differentiated derivatives (either 4d atRA or 10d EB).

Project description:We generated the human ES lines, in which the genome-wide reduction of H3K27me3 can be induced by the ectopic expression of catalytic domain of histone demethylase JMJD3 with doxycycline treatment (JMJD3c-hESCs). Genome-wide changes in H3K27me3 and H3K4me3 after JMJD3c overexpression were examined by ChIP-seq analyses.
Project description:Progenitor motor neurons can be generated with high-efficiency by differentiating ES cells in vitro in the presence of retinoic acid and hedgehog signalling. Here, we characterize the chromatin landscape associated with progenitor motor neurons (pMNs) in order to assess how histone modification domains shift during the differentiation process. In this study, we characterize the genomic occupancy of H3K27me3, H3K4me3, H3K79me2 and Pol2 using ChIP-seq in progenitor motor neurons that have been differentiated in vitro from ES cells. An appropriate whole-cell extract control experiment for these ChIP-seq experiments is also included.

Project description:ChIP-seq was performed to analyze genome-wide distribution of PARP-1 and histone marks H3K4me3, H3K27me3 in mES cells, and examine the effect of PARP-1 knockout on Sox2 and Oct4 genome-wide distribution in ES cells.
