Illumina HiSeq 2000
Description
The ability to assign expression patterns to individual cell types that constitute a tissue is a major challenge in RNA expression analysis. This especially applies to brain given the plethora of different cells coexisting in that tissue. Here, we derived cell-type specific transcriptome signatures from existing single cell RNA data and integrated these signatures with a newly generated dataset of expression (bulk RNA-seq) of the postnatal developing hippocampus. This integrated analysis allowed us to provide a comprehensive and unbiased prediction of the differentiation drivers for 10 different hippocampal cell types and describe how the different cell types interact to support crucial developmental stages. Our integrated analysis provides a reliable resource of predicted differentiation drivers and insight into the multifaceted aspects of the cells in hippocampus during development. Overall design: 21 RNA-seq samples. For the stages E15, P1, P7, P15, and P30, there are respectively 3, 4, 3, 3, and 6 RNA-seq biological replica (total 19). One RNA-seq sample has two technical replica.

Description
Multiple signaling pathways ultimately modulate the epigenetic information embedded in the chromatin of gene promoters by recruiting epigenetic enzymes. We found that, in estrogen-regulated gene programming, the acetyltransferase CREB-binding protein (CBP) is specifically and exclusively methylated by the coactivator-associated arginine methyltransferase (CARM1) in vivo. CARM1-dependent CBP methylation and p160 coactivators were required for estrogen-induced recruitment to chromatin targets. Notably, methylation increased the histone acetyltransferase (HAT) activity of CBP and stimulated its autoacetylation. Comparative genome-wide chromatin immunoprecipitation sequencing (ChIP-seq) studies revealed a variety of patterns by which p160, CBP, and methyl-CBP (meCBP) are recruited (or not) by estrogen to chromatin targets. Moreover, significant target gene-specific variation in the recruitment of (1) the p160 RAC3 protein, (2) the fraction of a given meCBP species within the total CBP, and (3) the relative recruitment of different meCBP species suggests the existence of a target gene-specific fingerprint for coregulator recruitment. Crossing ChIP-seq and transcriptomics profiles revealed the existence of meCBP hubs within the network of estrogen-regulated genes. Together, our data provide evidence for an unprecedented mechanism by which CARM1-dependent CBP methylation results in gene-selective association of estrogen-recruited meCBP species with different HAT activities and specifies distinct target gene hubs, thus diversifying estrogen receptor programming.

Description
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. Upon DNA damage, p53 directly regulates the transcription of 3644 genes (p<0.005) in mouse ES cells. Genome-wide analysis revealed a dramatic difference between the regulation of p53-activated and -repressed genes. p53 mainly regulates the promoter regions of activated genes, whereas the main regulatory regions for repressed genes reside in distal regions. Among p53-repressed genes, many are pluripotent transcription factors of ES cells, such as Oct4, Nanog, Sox2, Esrrb, c-Myc, n-Myc and Sall4. Strikingly, these transcriptional factors also directly regulate the transcription of the Trp53 gene, highlighting a previously under-estimated transcriptional regulation of p53 in ES cells. Therefore, p53 signaling and ES pluripotent transcriptional networks form an intertwined circuitry. Together, our results provide mechanistic insights into the crosstalk of p53-mediated DNA damage and ES cell "stemness" transcriptional gene networks and shed light on the tumor suppressive function of p53 in ES cells.
