The 3D Genome as Moderator of Chromosomal Communication

Open access
Dekker, Job, Mirny, Leonid·2016·Cell

Abstract

Proper expression of genes requires communication with their regulatory elements that can be located elsewhere along the chromosome. The physics of chromatin fibers imposes a range of constraints on such communication. The molecular and biophysical mechanisms by which chromosomal communication is established, or prevented, have become a topic of intense study, and important roles for the spatial organization of chromosomes are being discovered. Here we present a view of the interphase 3D genome characterized by extensive physical compartmentalization and insulation on the one hand and facilitated long-range interactions on the other. We propose the existence of topological machines dedicated to set up and to exploit a 3D genome organization to both promote and censor communication along and between chromosomes.

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

  • The observed contact probability trend is consistent with previous estimations and is representative of the contact probabilities experienced by promoters in mES cells.

    “This is consistent with previous estimations33 confirmed using cross-linking and ligation-free methods34 and is representative of the contact probabilities experienced by promoters in mES cells (Extended Data Fig. 2b, c).”
  • By regulating contact probability, TADs appear to be one of the determinants of functional and specific enhancer-promoter interactions.

    “Instead, by regulating contact probability, TADs appear to be one of the determinants of functional and specific enhancer-promoter interactions.29”
  • Two loci only contact each other ∼2-fold more frequently if they are within the same TAD instead of in different TADs.

    “Even though two loci only contact each other ∼2-fold more frequently if they are within the same TAD instead of in different TADs,29”

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.
