Abstract

Long-range cis-regulatory elements such as enhancers coordinate cell-specific transcriptional programmes by engaging in DNA looping interactions with target promoters. Deciphering the interplay between the promoter connectivity and activity of cis-regulatory elements during lineage commitment is crucial for understanding developmental transcriptional control. Here, we use Promoter Capture Hi-C to generate a high-resolution atlas of chromosomal interactions involving ~22,000 gene promoters in human pluripotent and lineage-committed cells, identifying putative target genes for known and predicted enhancer elements. We reveal extensive dynamics of cis-regulatory contacts upon lineage commitment, including the acquisition and loss of promoter interactions. This spatial rewiring occurs preferentially with predicted changes in the activity of cis-regulatory elements and is associated with changes in target gene expression. Our results provide a global and integrated view of promoter interactome dynamics during lineage commitment of human pluripotent cells.

  • Some contacts between PcG-associated regions, including poised promoters and enhancers in ESCs, are retained after these regions are activated during cell differentiation.

    “Notably, some contacts between PcG-associated regions, including poised promoters and enhancers in ESCs, are retained after these regions are activated during cell differentiation [141, 143].”

    From Transcriptional enhancers and their communication with gene promoters (2021) · cites this paper as [141]

    The Results section on rewiring and recolouring (Figure 6E–F; page not available) reports that some promoter interactions persist during ESC-to-NEC differentiation, including an IRX3 interaction whose promoter-interacting region changes from repressed to active. The Results section on regulatory elements also reports contacts between poised or Polycomb-associated promoters and similarly marked regions. The copy does not establish that the retained contacts specifically join poised promoters and enhancers that both become activated. (LLM, conf=0.82)

  • The chromatin state of the promoter at dual-state CRUs typically corresponded to the majority state of its enhancers, consistent with competition of opposing regulatory effects at the promoters.

    “the chromatin state of the promoter at dual-state CRUs typically corresponded to the majority state of its enhancers, consistent with a competition of opposing regulatory effects at the promoters.”

    From Transcriptional enhancers and their communication with gene promoters (2021) · cites this paper as [141]

    The Results section on CRU reorganisation reports that a promoter’s chromatin state generally matched the most prevalent state among its interacting regions. The Discussion section on regulation by multiple enhancers interprets this as possible ‘majority vote’ signal integration, but does not establish competition between opposing regulatory effects; it also offers independent enhancer action and promoter-state turnover as possible explanations. Page numbers are unavailable in our copy. (LLM, conf=0.83)

  • Upon early neural differentiation, about a third of single-state CRUs in human ESCs became dual-state, while around half of all dual-state CRUs became single-state.

    “Upon early neural differentiation, about a third of single-state CRUs in human ESCs became dual-state, while around half of all dual-state CRUs became single-state [141].”

    From Transcriptional enhancers and their communication with gene promoters (2021) · cites this paper as [141]

    The Results section (‘ESC differentiation is associated with the dynamic reorganisation of CRUs’; page unavailable) confirms that CRUs gained and lost dual-state configurations during ESC-to-NEC differentiation. But its figures use different denominators: 65% of initially single-state CRUs remained single-state, while 13% and 11% of CRUs acquired and lost dual-state configurations, respectively. It does not establish that a third of initially single-state CRUs became dual-state or that half of initially dual-state CRUs became single-state. (LLM, conf=0.86)

  • Some enhancers are marked with H3K27me3 alone and are considered to be Polycomb-repressed.

    “Finally, some enhancers are marked with H3K27me3 alone and are considered to be “Polycomb-repressed” [139–141].”
  • In mammals, PcG-associated promoters and enhancers engage in multitudes of looping contacts, particularly in early development.

    “In mammals, PcG-associated promoters and enhancers also engage in multitudes of looping contacts, particularly in early development [139, 141, 276, 357].”

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.
