Summary (written by the submitters)

Spatial genome organization and its effect on transcription remains a fundamental biological question. We applied an advanced ChIA-PET strategy to comprehensively map higher-order chromosome folding and chromatin interactions mediated by CTCF and RNAPII with haplotype specificity and nucleotide resolution in different human cell lineages.

We find that CTCF-mediated interaction anchors serve as structural foci for spatial organization of constitutive genes concordant with CTCF-motif orientation, whereas RNAPII interacts within these structures by selectively drawing cell-type-specific genes towards CTCF-foci and forming RNAPII foci for coordinated transcription. Furthermore, allelic-variants linked to disease susceptibility are found to impact chromatin topology and transcriptional regulation. Importantly, 3D-genome simulation suggested a model of chromatin folding around chromosomal axes, where CTCF involves in defining the interface between condensed and open compartments for structural regulation. Our new 3D-genome strategy thus provides novel insights to explore the topological mechanism of human variations and diseases.

Study design

6 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 6 sample titles: 6 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
