Abstract

Large-scale chromosome structure and spatial nuclear arrangement have been linked to control of gene expression and DNA replication and repair. Genomic techniques based on chromosome conformation capture (3C) assess contacts for millions of loci simultaneously, but do so by averaging chromosome conformations from millions of nuclei. Here we introduce single-cell Hi-C, combined with genome-wide statistical analysis and structural modelling of single-copy X chromosomes, to show that individual chromosomes maintain domain organization at the megabase scale, but show variable cell-to-cell chromosome structures at larger scales. Despite this structural stochasticity, localization of active gene domains to boundaries of chromosome territories is a hallmark of chromosomal conformation. Single-cell Hi-C data bridge current gaps between genomics and microscopy studies of chromosomes, demonstrating how modular organization underlies dynamic chromosome structure, and how this structure is probabilistically linked with genome activity patterns.

  • Some types of epigenetic modifications, such as changes in chromosome conformation, are still largely unexplored in MDD.

    “Some types of epigenetic modifications, such as changes in chromosome conformation are still largely unexplored in MDD.414,415”

    From Epigenetic regulation in major depression and other stress-related disorders: molecular mechanisms, clinical relevance and therapeutic potential (2023) · cites this paper as [414]

    The Single cell Hi-C section studies chromosome conformation in mouse T-helper cells, not major depressive disorder. The passages retrieved for MDD, depression, and an epigenetic research gap do not address whether chromosome-conformation changes are largely unexplored in MDD; the paper’s study of conformation alone cannot establish that claim.

  • Single-cell Hi-C can derive a coherent three-dimensional chromosomal topology unattainable from bulk 3C data, which averages the chromosomal conformations in millions of cells.

  • In the previous version of the single-cell Hi-C protocol, molecules supported by a single read (singleton contacts) usually represented spurious ligations and were therefore discarded.

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.
