Spatial promoter–enhancer hubs in cancer: organization, regulation, and function

Open access
Zhao, Jingru, Faryabi, Robert B.·2023·Trends in Cancer

Abstract

Transcriptional dysregulation is a hallmark of cancer and can be driven by altered enhancer landscapes. Recent studies in genome organization have revealed that multiple enhancers and promoters can spatially coalesce to form dynamic topological assemblies, known as promoter-enhancer hubs, which strongly correlate with elevated gene expression. In this review, we discuss the structure and complexity of promoter-enhancer hubs recently identified in multiple cancer types. We further discuss underlying mechanisms driving dysregulation of promoter-enhancer hubs and speculate on their functional role in pathogenesis. Understanding the role of promoter-enhancer hubs in transcriptional dysregulation can provide insight into new therapeutic approaches to target these complex features of genome organization.

  • GPC3 overexpression in HCC is accompanied by significant 3D interactions among constituent enhancers and between constituent enhancers and the promoter.

    “GPC3 overexpression was accompanied by significant 3D interactions amongst constituent enhancers as well as between constituent enhancers and the promoter (Fig. 3b)66,67.”

    From Multi-omic analysis of hepatocellular carcinoma reveals aberrant cis-regulatory changes and dysregulated retrotransposons with prognostic potential (2025) · cites this paper as [66]

    The Abstract (page unavailable) describes promoter–enhancer hubs and their association with elevated gene expression generally, but does not mention GPC3 or HCC. Searches for GPC3 and for hepatocellular carcinoma with enhancer–promoter interactions found no passage addressing the specific claim. (LLM, conf=0.72)

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.
