Abstract

All normal somatic cells are thought to acquire mutations, but understanding of the rates, patterns, causes and consequences of somatic mutations in normal cells is limited. The uterine endometrium adopts multiple physiological states over a lifetime and is lined by a gland-forming epithelium1,2. Here, using whole-genome sequencing, we show that normal human endometrial glands are clonal cell populations with total mutation burdens that increase at about 29 base substitutions per year and that are many-fold lower than those of endometrial cancers. Normal endometrial glands frequently carry ‘driver’ mutations in cancer genes, the burden of which increases with age and decreases with parity. Cell clones with drivers often originate during the first decades of life and subsequently progressively colonize the epithelial lining of the endometrium. Our results show that mutational landscapes differ markedly between normal tissues—perhaps shaped by differences in their structure and physiology—and indicate that the procession of neoplastic change that leads to endometrial cancer is initiated early in life. Whole-genome sequencing of normal human endometrial glands shows that most are clonal cell populations and frequently carry cancer driver mutations that occur early in life, and that parity has a protective effect.

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

  • The toolkit has a significant advantage to generate isogenic models of novel mutations in early tumorigenesis.

    “Taken together, these results demonstrate the significant advantage the toolkit we have developed in this study has to generate isogenic models of novel mutations in early tumorigenesis48,50–52.”
  • This hypothesis had never before been tested in an isogenic model.

    “While this hypothesis has been previously proposed48,50–52, it had never before been tested in an isogenic model.”

    From One-step generation of tumor models by base editor multiplexing in adult stem cell-derived organoids (2023) · cites this paper as [51]

    The cited paper’s Clonality of endometrial glands section discusses a proposed genetic-drift process, but does not say whether that hypothesis had previously been tested in an isogenic model. Searches for “isogenic model” and “hypothesis proposed tested model” found no passage addressing that claim. In the citing sentence, the references are attached to “previously proposed,” not explicitly to the assertion about prior testing. (LLM, conf=0.75)

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.
