Description
Mammalian genomes are organized into megabase-scale topologically associated domains (TADs) that have been proposed to represent large regulatory units. Here we demonstrate that disruption of TADs can cause rewiring of long-range regulatory architecture and result in pathogenic phenotypes. We show that distinct human limb malformations are caused by deletions, inversions, or duplications altering the structure of the TAD-spanning WNT6/IHH/EPHA4/PAX3 locus. Using CRISPR/Cas genome editing, we generated mice with corresponding rearrangements. Both in mouse limb tissue and patient-derived fibroblasts, disease-relevant structural changes cause ectopic interactions between promoters and non-coding DNA, and a cluster of limb enhancers normally associated with Epha4 is misplaced relative to TAD boundaries and drives ectopic limb expression of another gene in the locus. Our results demonstrate the functional importance of TADs for orchestrating gene expression via genome architecture and indicate criteria for predicting the pathogenicity of human structural variants, particularly in non-coding regions of the human genome. Overall design: RNA-seq profile of developing distal limbs of mutants and WT animals at E11.5

Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
The nuclear hormone receptor, estrogen receptor-alpha (ER), and MAP kinases both play key roles in hormone-dependent cancers, yet their interplay and the integration of their signaling inputs remain poorly understood. In these studies, we document that estrogen-occupied ER activates and interacts with ERK2, a downstream effector in the MAPK pathway, resulting in ERK2 and ER colocalization at chromatin binding sites across the genome of breast cancer cells.

Description
Acute myeloid leukemia (AML) is a complex, heterogeneous disease with variable outcomes following curative intent chemotherapy. AML with inv(3) is a genetic subgroup characterized by low response rate to induction type chemotherapy and hence is among the worst long term survivorship of the AMLs. Here, we present RNA-Seq transcriptome data from OCI-AML-20, a new AML cell line with inv(3) and deletion of chromosome 7. Overall design: RNA-Seq transcriptome analysis of OCI-AML-20 cell line with three biological replicates.

Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
Cancer is characterized by gene expression aberrations. Studies have largely focused on coding sequences and promoters, despite the fact that distal regulatory elements play a central role in controlling transcription patterns. Here we utilize the histone mark H3K4me1 to analyze gain and loss of enhancer activity genome wide in primary colon cancer lines relative to normal colon crypts. We identified thousands of variant enhancer loci (VELs) that comprise a signature that is robustly predictive of the in vivo colon cancer transcriptome. Furthermore, VELs are enriched in haplotype blocks containing colon cancer genetic risk variants, implicating these genomic regions in colon cancer pathogenesis. We propose that reproducible changes in the epigenome at enhancer elements drive a unique transcriptional program to promote colon carcinogenesis.
