Abstract

Recent studies have highlighted super-enhancers (SEs) as important regulatory elements for gene expression, but their intrinsic properties remain incompletely characterized. Through an integrative analysis of Hi-C and ChIP-seq data, here we find that a significant fraction of SEs are hierarchically organized, containing both hub and non-hub enhancers. Hub enhancers share similar histone marks with non-hub enhancers, but are distinctly associated with cohesin and CTCF binding sites and disease-associated genetic variants. Genetic ablation of hub enhancers results in profound defects in gene activation and local chromatin landscape. As such, hub enhancers are the major constituents responsible for SE functional and structural organization.

  • Facilitators, as described here, may be relatively common elements in multipartite enhancers.

    “Review of diverse, albeit incomplete, previous analyses of SEs16,17,19,20,22 suggest that facilitators, as described here, may be relatively common elements in multipartite enhancers.”

    From Super-enhancers include classical enhancers and facilitators to fully activate gene expression (2023) · cites this paper as [20]

    The Results sections “A subset of SEs contains hierarchical structure” and “Hub enhancers are enriched with cohesin and CTCF binding” report hierarchical super-enhancers in 23% and 34% of two cell-line datasets and describe hub enhancers that facilitate chromatin interactions. This supports the suggestion that facilitating elements occur in a substantial subset of super-enhancers, but the paper does not establish that the citing authors’ ‘facilitators’ are the same elements or that they are common across multipartite enhancers generally.

  • When comparing Borzoi, Enformer and a distance-to-TSS baseline on classifying measured positive from negative enhancer-gene interactions, Borzoi has superior AUPRC and AUROC at all distances.

    “When comparing Borzoi, Enformer and a distance-to-TSS baseline on their ability to classify measured positive from negative enhancer–gene interactions in data from previous works60–65, we find that Borzoi has superior average precision (AUPRC) and area under the receiver operating characteristic curve (AUROC) at all distances (Fig. 4c and Extended Data Fig. 5a).”

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.
