Abstract

Hi-C and chromatin immunoprecipitation (ChIP) have been combined to identify long-range chromatin interactions genome-wide at reduced cost and enhanced resolution, but extracting information from the resulting datasets has been challenging. Here we describe a computational method, MAPS, Model-based Analysis of PLAC-seq and HiChIP, to process the data from such experiments and identify long-range chromatin interactions. MAPS adopts a zero-truncated Poisson regression framework to explicitly remove systematic biases in the PLAC-seq and HiChIP datasets, and then uses the normalized chromatin contact frequencies to identify significant chromatin interactions anchored at genomic regions bound by the protein of interest. MAPS shows superior performance over existing software tools in the analysis of chromatin interactions from multiple PLAC-seq and HiChIP datasets centered on different transcriptional factors and histone marks.

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

  • Chromatin loops connecting active promoters to distal regulatory regions were found in microglia, neurons, and oligodendrocytes.

    “Chromatin loops were identified between active promoters and distal regulatory regions in microglia, neurons and oligodendrocytes (26).”

    From Brain cell type–specific enhancer–promoter interactome maps and disease <b>-</b> risk association (2019) · cites this paper as [26]

    The Introduction (page unavailable) says distal enhancers frequently form chromatin loops with target-gene promoters, supporting the general type of interaction. The Results and Methods passages describe analyses in mouse embryonic stem cells and GM12878 cells, not microglia, neurons, or oligodendrocytes. Our copy therefore does not support the claim that these loops were identified in the three named cell types. (LLM, conf=0.86)

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.
