GenomicsLarge-Scale Discovery of Enhancers from Human Heart Tissue
Development and function of the human heart depend on the dynamic control of tissue-specific gene expression by distant-acting transcriptional enhancers. While large numbers of heart enhancers have been identified using the mouse as a model system, many of these regulatory sequences are poorly cons...

GenomicsA High-Resolution Enhancer Atlas of the Developing Telencephalon
The mammalian telencephalon plays critical roles in cognition, motor function, and emotion. While many of the genes required for its development have been identified, the distant‐acting regulatory sequences orchestrating their in vivo expression are mostly unknown. Here we describe a digital atlas o...

GenomicsChIP-seq Accurately Predicts Tissue-Specific Activity of Enhancers
Determining the spatial and temporal activity patterns of enhancers remains a challenge in the functional annotation of the human genome. Here, we performed genome-wide mapping of tissue-specific in vivo binding sites for the enhancer-associated protein p300 and assessed in transgenic mice the util...

GenomicsChIP-seq Identification of Weakly Conserved Heart Enhancers
Accurate control of tissue-specific gene expression plays a pivotal role in heart development. However, few cardiac transcriptional enhancers have thus far been identified. Extreme non-coding sequence conservation successfully predicts enhancers active in many tissues, but fails to identify substan...

GenomicsRapid and Pervasive Changes in Genome-Wide Enhancer Usage During Mammalian Development
Here we used epigenomic profiling for H3K27ac, a mark of active enhancers to examine the genome-wide in vivo utilization of enhancers in three different mouse tissues across seven developmental stages, ranging from mid-gestation through adulthood. The majority of the ~90,000 enhancers identified exh...

GenomicsChromatin stretch enhancer states drive cell-specific gene regulation and harbor human disease risk variants (ChIP-seq)
Chromatin-based functional genomic analyses and genomewide association studies (GWASs) together implicate enhancers as critical elements influencing gene expression and risk for common diseases. Here, we performed systematic chromatin and transcriptome pro- filing in human pancreatic islets. Integra...

GenomicsReinstatement of developmental stage-specific GATA4 enhancers controls the gene expression program in heart disease
Through integration of GATA4 genome-wide occupancy and RNA-seq dataset in embryonic conditional knockout heart, we identified a class of the master cardiac regulator GATA4 bound enhancers. With combinatorial assembly of chromatin signatures, we further refined that a unique type of fetal distal GATA...

GenomicsEpigenetic and genetic features that lead to discovery of enhancer function
The ability to measure epigenetic features, such as histone modifications and occupancy by transcription factors and co-activators, on a genome-wide scale is advancing the accuracy of CRM predictions. While integration of signals from multiple features is expected to improve predictions, the contrib...
