Abstract

To understand the role of the extensive senescence-associated 3D genome reorganization, we generated genome-wide chromatin interaction maps, epigenome, replication-timing, whole-genome bisulfite sequencing, and gene expression profiles from cells entering replicative senescence (RS) or upon oncogene-induced senescence (OIS). We identify senescence-associated heterochromatin domains (SAHDs). Differential intra- versus inter-SAHD interactions lead to the formation of senescence-associated heterochromatin foci (SAHFs) in OIS but not in RS. This OIS-specific configuration brings active genes located in genomic regions adjacent to SAHDs in close spatial proximity and favors their expression. We also identify DNMT1 as a factor that induces SAHFs by promoting HMGA2 expression. Upon DNMT1 depletion, OIS cells transition to a 3D genome conformation akin to that of cells in replicative senescence. These data show how multi-omics and imaging can identify critical features of RS and OIS and discover determinants of acute senescence and SAHF formation.

  • Recent advances in 3D DNA FISH such as OligoSTORM can be used to study local changes in the 3D structure of senescent chromosomes in individual cells identified by genomic techniques such as Hi-C.

    “Recent advances in 3D DNA FISH such as OligoSTORM can also be used to study, in more detail, local changes in the 3D structure of senescent chromosomes in individual cells that have been identified by genomic techniques such as high-throughput chromosome conformation capture (Hi-C)40,41.”

    From Spatial mapping of cellular senescence: emerging challenges and opportunities (2023) · cites this paper as [41]

    The Introduction and Results describe using oligopaint-based 3D DNA FISH alongside Hi-C to examine chromosome organization in senescent cells. The paper does not identify its method as OligoSTORM: the Methods describe confocal imaging, so it supports the combined approach but not that specific example. (LLM, conf=0.85)

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.
