TranscriptomicsMolecular architecture of transcription factor hotspots in early adipogenesis
Here, we have used digital genomic footprinting to precisely define protein localization for several adipogenic transcription factors at a genome-wide level. In combination with ChIP-seq data, these analyses reveal novel molecular insight into the organization of transcription factors at hotpot regi...

TranscriptomicsChromosome conformation capture-on-chip of glucocorticoid receptor-responsive loci in mouse cells
The spatial organization of genes in the interphase nucleus plays an important role in establishment and regulation of gene expression. Contradicting results have been reported to date, with little consensus about the dynamics of nuclear organization and the features of the contact loci. In this s...

GenomicsMultiple Overlapping Mammalian Chromatin Remodeling Systems Collaborate Genome-wide at Dynamic Chromatin Transitions (ChIP-Seq)
ATP-dependent chromatin remodeling is an essential process required for the dynamic organization of chromatin structure. Here we describe the genome-wide location and activity of three remodeler proteins with diverse physiological functions in the mouse genome: Brg1, Chd4, and Snf2h. The localizatio...

GenomicsGR and Pol II interactions with regulatory elements in response to ultradian (pulsed) hormone stimulation [ChIP-seq]
We report changes in GR and Pol II binding profiles genome-wide upon treatment with corticosterone (Cort) for 20 minutes, treatment with Cort for 20 minutes followed by hormone withdrawal for 40 minutes, 60 minutes continuous stimulation with Cort, and 60 minutes continuous stimulation with Dexamet...

TranscriptomicsThree-dimensional proximity mapping of the DRGFP DNA double-strand break site in U2OS cells
We mapped the DNA sequences located in physical proximity to an I-SceI endonuclease-dependent DNA double-strand break (DSB) site to be able to study the impact of DSBs on the break-associated chromatin micro-environment. The I-SceI DSB site is part of a DRGFP transgene that serves as a reporter for ...

GenomicsExtensive Chromatin Remodeling and Establishment of Transcription Factor 'Hotspots' during Early Adipogenesis
Adipogenesis is tightly controlled by a complex network of transcription factors acting at different stages of differentiation. Peroxisome proliferator-activated receptor gamma (PPAR gamma) and CCAAT/enhancer binding protein (C/EBP) family members are key regulators of this process. We have employ...
