Abstract

Capture Hi-C (CHi-C) is a method for profiling chromosomal interactions involving targeted regions of interest, such as gene promoters, globally and at high resolution. Signal detection in CHi-C data involves a number of statistical challenges that are not observed when using other Hi-C-like techniques. We present a background model and algorithms for normalisation and multiple testing that are specifically adapted to CHi-C experiments. We implement these procedures in CHiCAGO ( http://regulatorygenomicsgroup.org/chicago ), an open-source package for robust interaction detection in CHi-C. We validate CHiCAGO by showing that promoter-interacting regions detected with this method are enriched for regulatory features and disease-associated SNPs.

  • A similar network of contacts is detectable between active promoters of multiple histone genes in many mammalian cell types.

    “A similar network of contacts is also detectable between the active promoters of multiple histone genes in many mammalian cell types [243, 279, 471, 492].”

    From Transcriptional enhancers and their communication with gene promoters (2021) · cites this paper as [471]

    In Results, under “Promoter interactions detected by CHiCAGO: validation and key properties” (page unavailable), the paper reports frequent contacts between histone-gene promoters on chromosome 6 in GM12878 cells. It does not establish that those promoters are active or that the same network is detectable in many mammalian cell types; its findings about active histone marks concern promoter-interacting fragments generally, not this histone-gene network. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Many computational algorithms for Hi-C analysis explicitly correct for distance decay, identifying significant interactions based on how unusual their contact frequency is at a given distance.

    “many computational algorithms for the analysis of data from Hi-C and related techniques explicitly correct for distance decay, identifying “significant interactions” based on how unusual their contact frequency is at a given distance [277, 468–471].”

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.
