Recent studies revealed that chromosomes are organized into megabase-scale domains that demarcate active and inactive genetic elements, suggesting that compartmentalization is important for genome function. Here we show that very specific long-range interactions are anchored by cohesin/CTCF sites, but not cohesin-only or CTCF-only sites, to form a hierarchy of chromosomal loops. These loops demarcate topological domains and form intricate internal structures within them. Post-mitotic nuclei deficient for functional cohesin exhibit global architectural changes associated with loss of cohesin/CTCF contacts and relaxation of topological domains. Transcriptional analysis shows that this cohesin-dependent perturbation of domain organization leads to widespread gene deregulation of both cohesin-bound and non-bound genes. Our data thereby support a role for cohesin in the global organization of domain structure and suggest that domains function to stabilize the transcriptional programs within them. Hi-C, ChIP-Seq and RNA-Seq experiments were conducted in mouse neural stem cells and mouse astrocytes Term Source Name ArrayExpress EFO Term Source File http://www.ebi.ac.uk/arrayexpress/ http://www.ebi.ac.uk/efo/efo.owl Person Last Name Hadjur Sofueva Yaffe Chan Georgopoulou Vietri-Rudan Pollard Schroth Tanay Hadjur Person First Name Suzana Sevil Eitan Wen-Ching Dimitra Matteo Steven Gary Amos Suzana Person Mid Initials M P Person Email s.hadjur@ucl.ac.uk Person Affiliation Ucl Person Phone +44 7798957199 Person Address Cancer biology, Ucl, 72 Huntley street, London, United Kingdom Person Roles submitter Protocol Name P-GSE48965-1 P-GSE48965-3 P-GSE48965-2 Protocol Description To delete Rad21, cells were treated with AdCre for 72 or 96hr RNA was extracted using qiagen RNAeasy columns. Cells were treated with accutase, washed and immediately flash frozen. RNA was prepared using standard protocols and only high quality RNA (RIN>8) was used downstream. RNA was fragmented, PE adapters were ligated and libraries amplified according to the Illumina TruSeq protocol Cells were grown in serum-free media containing BMP+FGF and Laminin Protocol Type sample treatment protocol nucleic acid library construction protocol growth protocol Experimental Factor Name TIME GENOTYPE Experimental Factor Type time genotype Publication Title Cohesin-mediated interactions organize chromosomal domain architecture.
