TranscriptomicsExtensive promoter-centered chromatin interactions provide a topological basis for transcription regulation
Higher-order chromosomal organization for transcription regulation is poorly understood in eukaryotes. Using genome-wide Chromatin Interaction Analysis with Paired-End-Tag sequencing (ChIA-PET), we mapped long-range chromatin interactions associated with RNA polymerase II in human cells and uncovere...

GenomicsCharacterization of genome-wide enhancer-promoter interactions reveals co-expression of interacting genes and modes of higher order chromatin organization
Recent epigenomic studies have predicted thousands of potential enhancers in the human genome. However, there has not been systematic characterization of target promoters for these potential enhancers. Using H3K4me2 as a mark for active enhancers, we identified genome-wide enhancer-promoter interact...

GenomicsAn Estrogen Receptor α-bound Human Chromatin Interactome
We developed Chromatin Interaction Analysis by Paired-End Tag sequencing (ChIA-PET) for de novo detection of global chromatin interactions, and comprehensively mapped the chromatin interaction network bound by estrogen receptor α (ERα) in the human genome. We performed 454 and Illumina sequencing an...

TranscriptomicsCell type specificity of chromatin organization mediated by CTCF and cohesin
CTCF sites are abundant in the genomes of diverse species but their function is enigmatic. We used chromosome conformation capture to determine long-range interactions among CTCF/cohesin sites over 2 Mb on human chromosome 11 encompassing the β-globin locus and flanking olfactory receptor genes. Alt...

GenomicsGlobal Reorganization of Chromatin Architecture during Embronic Stem Cell Differentiation
The 3D organization of the genome is important for regulation of diverse nuclear processes ranging from transcription to DNA replication. Knowledge of the higher order chromatin structure is critical for understanding mechanisms of gene regulation by long-range control elements such as enhancers and...

TranscriptomicsA mouse model of endemic Burkitt translocations reveals the long-range boundaries of Ig-mediated oncogene deregulation
Igh/Myc translocations underlie both sporadic Burkitt lymphoma (BL) and the endemic clinical form affecting African children infected with malaria. However, while sporadic translocations decapitate Myc from 5' proximal regulatory elements, most endemic events occur hundreds of kilobases away from My...

GenomicsFlexible chromatin loops in the VH gene region of the Igh locus facilitate the generation of a diverse antibody repertoire
The immunoglobulin heavy-chain (Igh) locus undergoes large-scale contraction in pro-B cells, which facilitates VH-DJH recombination by juxtaposing distal VH genes next to the DJH- rearranged gene segment in the proximal Igh domain. By high-resolution mapping of long-range interactions, we now demons...

GenomicsGenome-wide Analysis of Chromatin Interactions in Human Cells
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 unrelate...

Transcriptomics3C-seq of HT29 cells with CCAT1-L knockdown or scramble knockdown
CCAT1-L is a highly expressed long noncoding RNA located in the colorectal cancer specific super enhance region about 500 kb upstream of MYC gene. Knockdown of CCAT1-L significantly down-regulated interaction frequency between CCAT1 and MYC locus and repress MYC expression, suggesting a long-range c...
