Project description:As the most widely used mammalian model organism, mice play a critical role in biomedical research for mechanistic study of human development and diseases. Today, functional sequences in the mouse genome are still poorly annotated a decade after its initial sequencing. We report here a map of nearly 300,000 cis-regulatory sequences in the mouse genome, representing active promoters, enhancers and CTCF binding sites in a diverse set of 19 tissues and cell types. This map provides functional annotation to nearly 11% of the genome, and over 70% of conserved, non-coding sequences. We define tissue-specific enhancers and identify potential transcription factors regulating gene expression in each tissue or cell type. Finally, we demonstrate that cis-regulatory sequences are organized into domains of coordinately regulated enhancers and promoters. Our results provide a valuable resource for the annotation of functional elements in the mammalian genome, and study of regulatory mechanisms for tissue-specific gene expression. 19 tissues and primary cell types were examined.

Project description:The laboratory mouse is the most widely used mammalian model organism in biomedical research. The 2.6 billion bases of the mouse genome share a high degree of conservation with the human genome, so a thorough annotation of the mouse genome will be of significant value to understanding the function of the human genome. To date, most of the functional sequences in the mouse genome have yet to be found, and the cis-regulatory sequences in particular are still poorly annotated. Comparative genomics has been a powerful tool for the discovery of these sequences, but it alone cannot resolve their temporal and spatial functions. Recently, ChIP-Seq has been developed to identify cis-regulatory elements in the genomes of several organisms including human, D. melanogaster and C. elegans. We have applied the same experimental approach to a diverse set of 19 tissues and cell types in the mouse, producing a map of nearly 300,000 murine cis-regulatory sequences. This map provides functional annotation to nearly 11% of the mouse genome, and over 70% of conserved, non-coding sequences (CNS). We define tissue-specific enhancers and identify potential transcription factors regulating gene expression in each tissue or cell type. Finally, we demonstrate that much of the mouse genome is organized into domains of coordinately regulated enhancers and promoters. Our results provide a resource for the annotation of functional elements in the mammalian genome and study of mechanisms regulating tissue-specific gene expression. This SuperSeries is composed of the SubSeries listed below.

Project description:The zebrafish has been widely used for the study of human disease and development, as ~70% of the protein-coding genes are conserved between the two species. Annotation of functional control elements of the zebrafish genome, however, has lagged behind that of other model systems such as mouse and Drosophila. Based on multi-omics approaches taken in the ENCODE and Roadmap Epigenomics projects, we performed RNA-seq, ATAC-seq, ChIP-seq and Hi-C experiments in ten adult and two embryonic tissues to generate a comprehensive map of transcriptomes and regulatory elements in the zebrafish Tuebingen reference strain. Overall, we have identified 235,596 cis-regulatory elements, which potentially shape the tissue-specific and developmental-stage-specific gene expression in zebrafish. A comparison of zebrafish, human, and mouse regulatory elements allowed us to identify both evolutionarily conserved and species-specific regulatory sequences. Furthermore, through the analysis of Hi-C data in zebrafish brain and muscle, we observed different levels of 3D genome organization, including compartment, topological associating domains (TADs), and chromatin loops in zebrafish. A subset of TADs are deeply conserved between zebrafish and human. This work provides an additional epigenomic anchor for the functional annotation of vertebrate genomes and the study of evolutionally conserved elements of 3D genome organization.

Project description:Millions of cis-regulatory sequences have recently been found in the human genome, but the function of most cis-elements are not yet clear, in part due to the difficulty in determining their regulatory targets, which are often located millions of base pairs away and separated by one or more unrelated genes. To address this problem, the Hi-C method has been developed to identify long-range looping interactions in a genome-wide, unbiased fashion. However, current data analysis of Hi-C datasets cannot fully resolve regulatory interactions between enhancers and promoters due to the low resolution. Here, we generated a high-depth Hi-C dataset and applied a new analysis method that offers improved resolution permitting genome-wide identification of nearly one million chromatin interactions. We demonstrated the use of Hi-C to identify target promoters of enhancers regulated by NF-M-NM-:B signaling and signal-dependent dynamic chromatin interaction at these enhancers in human cells. Surprisingly, our results showed that most NF-M-NM-:B binding sites are looped to their regulatory targets prior to activation of the signaling pathway, and appear to undergo little change during signaling. This observation suggests that the chromatin organization landscape, once established in a cell type, is rather stable and may influence the selection and activation of target genes by a transcription factor. We performed Hi-C analysis using a human fibroblast cell line IMR90 before and after NF-M-NM-:B activation. In the meantime, we also performed ChIP-seq experiments to map the location of NF-M-NM-:B p65 subunit, RNA polymerase II, p300, and several histone modifications (including H3K4me1, H3K4me3, H3K27ac and H3K36me3) in IMR90 cells before and after transient TNF-M-NM-1 stimulation. Additionally, to monitor the dynamic transcription profiles, we also performed Global Run-On sequencing (GRO-seq).

Project description:The basic body plan and major physiological axes have been highly conserved during mammalian evolution, yet only a small fraction of the human genome sequence appears to be subject to evolutionary constraint. To quantify cis- versus trans-acting contributions to mammalian regulatory evolution, we performed genomic DNase I footprinting of the mouse genome across 25 cell and tissue types, collectively defining ~8.6 million transcription factor (TF) occupancy sites at nucleotide resolution. Here we show that mouse TF footprints conjointly encode a regulatory lexicon that is ~95% similar with that derived from human TF footprints. However, only ~20% of mouse TF footprints have human orthologues. Despite substantial turnover of the cis-regulatory landscape, nearly half of all pairwise regulatory interactions connecting mouse TF genes have been maintained in orthologous human cell types through evolutionary innovation of TF recognition sequences. Furthermore, the higher-level organization of mouse TF-to-TF connections into cellular network architectures is nearly identical with human. Our results indicate that evolutionary selection on mammalian gene regulation is targeted chiefly at the level of trans-regulatory circuitry, enabling and potentiating cis-regulatory plasticity. We performed genomic DNase I footprinting of the mouse genome across 25 cell and tissue types, collectively defining ~8.6 million transcription factor (TF) occupancy sites at nucleotide resolution.
