(Submitter supplied) The human genome shares a remarkable amount of genomic sequence with our closest living primate relatives. Researchers have long sought to understand what regions of the genome are responsible for unique species-specific traits. Previous studies have shown that many genes are differentially expressed between species, but the regulatory elements contributing to these differences are largely unknown. Here we report a genome-wide comparison of active gene regulatory elements in human, chimpanzee, and macaque, and we identify hundreds of regulatory elements that have been gained or lost in the human or chimpanzee genomes since their evolutionary divergence. These elements contain evidence of natural selection and correlate with species-specific changes in gene expression. Polymorphic DNA bases in transcription factor motifs that we found in these regulatory elements may be responsible for the varied biological functions across species. This study directly links phenotypic and transcriptional differences between species with changes in chromatin structure.

(Submitter supplied) Evolution of transcriptional regulation is thought to be a major cause of the evolution of phenotypic traits. We compared DNase I Hypersensitive sites in fibroblast cells from five primates (human, chimpanzee, gorilla, orangutan, and macaque). We identified approximately 90,000 DHS sites, of which 59% are not significantly different between species, 27% are differential and likely due to a single evolutionary change, and 14% are differential and likely due to multiple changes. more...

(Submitter supplied) To study the evolutionary dynamics of regulatory DNA, we mapped >1.3 million deoxyribonuclease I–hypersensitive sites (DHSs) in 45 mouse cell and tissue types, and systematically compared these with human DHS maps from orthologous compartments. We found that the mouse and human genomes have undergone extensive cis-regulatory rewiring that combines branch-specific evolutionary innovation and loss with widespread repurposing of conserved DHSs to alternative cell fates, and that this process is mediated by turnover of transcription factor (TF) recognition elements. more...

(Submitter supplied) Gene expression is controlled by the complex interaction of transcription factors binding to promoters and other regulatory DNA elements. One common characteristic of the genomic regions associated with regulatory proteins is a pronounced sensitivity to DNase I digestion. We reported genome-wide high resolution maps of DNase I hypersensitive (DH) sites from both seedling and flower tissues of Arabidopsis from the Columbia (Col) ecotype and the corresponding ddm1 (deficient in DNA methylation 1) mutant. more...

(Submitter supplied) The vertebrate-specific transcription factor RE-1 silencing transcription factor or neuron-restrictive silencer factor (REST/NRSF) was first described as a negative regulator restricting expression of neuronal genes to neurons in a variety of genetic contexts. However, REST/NRSF has a more general role in the regulation of gene expression that involves chromatin remodelling via a SWI/SNF complex. We identified a 677 gene repertoire of potential REST/NRSF-dependent genes taking advantage of Rest/Nrsf gene silencing in a mouse cell line. more...

(Submitter supplied) The molecular mechanisms that lead to the cognitive defects characteristic of Down syndrome (DS), the most frequent cause of mental retardation, have remained elusive. Here we use a transgenic DS mouse model to show that DYRK1A gene dosage imbalance deregulates chromosomal clusters of genes located near neuron-restrictive silencer factor (REST/NRSF) binding sites. We found that DYRK1A binds the SWI/SNF-complex known to interact with REST/NRSF. more...

(Submitter supplied) Identifying the chromosomal targets of transcription factors is important for reconstructing the transcriptional regulatory networks underlying global gene expression programs. We have developed an unbiased genomic method called sequence tag analysis of genomic enrichment (STAGE) to identify the direct binding targets of transcription factors in vivo. STAGE is based on high-throughput sequencing of concatemerized tags derived from target DNA enriched by chromatin immunoprecipitation. more...

(Submitter supplied) To perform FAIRE, chromatin is crosslinked with formaldehyde in vivo, sheared by sonication, and phenol-chloroform extracted. The DNA recovered in the aqueous phase is fluorescently labeled and hybridized to a DNA microarray. FAIRE performed in human cells strongly enriches DNA coincident with the location of DNaseI hypersensitive sites, transcriptional start sites, and active promoters.
