(Submitter supplied) Tumor suppressor p53 promotes differentiation of human embryonic stem cells (hESCs), but an in-depth understanding of mechanism is lacking. Here, we define p53 functions in hESCs by genome wide profiling of p53 chromatin interactions and intersection with gene expression during early differentiation and in response to DNA damage. During differentiation, p53 targets and regulates a unique collection of genes, many of which encode transcription factors and developmental regulators with chromatin structure poised by OCT4 and NANOG and marked by repressive H3K27me3 in pluripotent hESCs. more...

(Submitter supplied) Recent evidence suggests that lncRNAs play an integral regulatory role in numerous functions, including determination of cellular identity. We determined global expression (RNA-seq) and genome wide profiles (ChIP-seq) of histone post-translational modifications and p53 binding in human embryonic stem cells (hESCs) undergoing differentiation to define a high-confidence set of 40 lncRNAs, which are p53 transcriptional targets. more...

(Submitter supplied) Neurogenesis entails a highly orchestrated process from pluripotent to neural cell fates including progenitors (NPCs) and various neural subtypes. However, the precise epigenetic mechanisms underlying the fate decision remain poorly understood. Here, we deleted KDM6s (JMJD3 or/and UTX), the demethylases for H3K27me3, in human embryonic stem cells (hESCs) and show that their deletion does not impede NPC generation from hESCs. more...

(Submitter supplied) Study of the function of p53 in regulating gene expression in mouse embryonic stem cells. It is critical for embryonic stem cells to maintain their genomic stability. The guardian of the genome, p53, plays important roles in maintaining the genomic integrity of ES cells through regulating the differentiation of ES cells. However, the underlying mechanism of this differentiation is still unclear. We plan to use the integrative genome-wide approach, combining ChIP-seq and gene expression microarray, to explore the mechanisms.

(Submitter supplied) The tumor suppressor p53 regulates the differentiation of embryonic stem (ES) cells upon DNA damage. However, our understanding of this critical tumor suppressive role of p53 in ES cells is limited, mainly because of the lack of molecular mechanism. Here, we report a widespread cross-regulation of p53-mediated DNA damage signaling and the pluripotent gene network in ES cells using chromatin-immunoprecipitation assay-based sequencing (ChIP-seq) and gene expression microarray. more...

(Submitter supplied) Genome-wide analysis of gene expression changes in murine embryonic stem cells (R1E cells) treated with Ultraviolet and adriamycin Both p53 and the Wnt signaling pathways play important roles in tumorigenesis and development. However, few studies, particularly on a genome-wide scale, have linked these two pathways. Here we show that p53 directly regulates the Wnt signaling pathway in murine embryonic stem cells (mESCs) using an integrated genome-wide approach. more...

(Submitter supplied) To elucidate the Nodal transcriptional network that governs endoderm formation, we used ChIP-Seq to identify genomic targets for SMAD2/3, SMAD3, SMAD4, FOXH1 and the active and repressive chromatin marks, H3K4me3 and H3K27me3, in human embryonic stem cells (hESCs) and derived endoderm. We demonstrate that while SMAD2/3, SMAD4 and FOXH1 target binding is highly dynamic, there is an optimal signature for driving endoderm commitment. more...

(Submitter supplied) The JmjC domain containing protein JMJD3/KDM6B catalyses H3K27me3 and H3K27me2 demethylation. JMJD3 appears to be highly regulated at the transcriptional level and is upregulated in response to diverse stimuli such as differentiation inducers and stress signals. Accordingly, JMJD3 has been linked to the regulation of different biological processes such as differentiation of embryonic stem cells, inflammatory responses in macrophages, and induction of cellular senescence via regulation of the INK4A-ARF locus. more...

(Submitter supplied) H3K27me3 represses developmental genes at initial embryonic stages. The KDM6 family, comprised of UTX and JMJD3, are the only known proteins that demethylate H3K27me3 and they are hypothesized to catalyze the rapid removal of repressive chromatin in early mammalian development. However, we report that male embryos carrying mutations in both Utx and Jmjd3 survive to term and appear phenotypically normal at mid-gestation. more...
