Abstract

Understanding the topological configurations of chromatin may reveal valuable insights into how the genome and epigenome act in concert to control cell fate during development. Here, we generate high-resolution architecture maps across seven genomic loci in embryonic stem cells and neural progenitor cells. We observe a hierarchy of 3D interactions that undergo marked reorganization at the submegabase scale during differentiation. Distinct combinations of CCCTC-binding factor (CTCF), Mediator, and cohesin show widespread enrichment in chromatin interactions at different length scales. CTCF/cohesin anchor long-range constitutive interactions that might form the topological basis for invariant subdomains. Conversely, Mediator/cohesin bridge short-range enhancer-promoter interactions within and between larger subdomains. Knockdown of Smc1 or Med12 in embryonic stem cells results in disruption of spatial architecture and downregulation of genes found in cohesin-mediated interactions. We conclude that cell-type-specific chromatin organization occurs at the submegabase scale and that architectural proteins shape the genome in hierarchical length scales.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The Sox2 gene has an essential enhancer, the Sox2 Control Region (SCR), which was found by 3C-derived techniques to loop to the Sox2 promoter.

    “The Sox2 gene has an essential enhancer, the Sox2 Control Region (SCR), which was found by 3C-derived techniques to loop to the Sox2 promoter (for example, [379, 401]).”

    From Transcriptional enhancers and their communication with gene promoters (2021) · cites this paper as [379]

    In Results, “Constitutive and cell type-specific features of 3-D chromatin organization” (page unavailable), the paper reports that 5C data show looping interactions between Sox2 and a putative downstream enhancer in ES cells. It does not identify that enhancer as the Sox2 Control Region (SCR) or establish that it is essential. (LLM, conf=0.87)

  • The cohesin complex is an important architectural protein that organizes the 3D genome and is also important in DSB repair.

  • Interaction scores have proven to be informatively comparable across replicates and conditions.

    “Interaction scores have proven to be informatively comparable across replicates and conditions21”
  • CTCF/Cohesin sites dispersed within TADs are thought to contribute to the formation of smaller self-interacting domains termed sub-TADs, contact domains, and insulated neighborhoods.

    “These CTCF/Cohesin sites are thought to contribute to the formation of smaller self-interacting domains that have been termed sub-TADs18, contact domains19, and insulated neighborhoods11,20.”
  • There is enrichment for CTCF at human ES cell boundaries compared to loci internal to domains.

    “Consistent with previous reports, we found enrichment for the architectural protein CCCTC-binding factor (CTCF) at human ES cell boundaries compared to loci internal to domains (Figure S6A-B) (Dixon et al., 2012; Nora et al., 2012; Phillips-Cremins et al., 2013).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
