Abstract

Movement in the Cancer Genome: Transposable elements are genetic sequences that can replicate and move within the genome. The factors that make an element mobile are unknown but are generally considered rare in mammals. Lee et al. (p. 967 , published online 28 June) analyzed five cancer types occurring among several individuals and found that three types of epithelial tumors exhibited high rates of element movement relative to brain and blood cancers. Furthermore, these somatically acquired, tumor-specific elements targeted genes in colorectal cancer that, when disrupted, impact gene expression and thus may be a factor in the progression of the cancers.

  • Cancer is characterized by genomic instability and in many cases increased expression of L1 elements.

    “Cancer is characterized by genomic instability and in many cases increased expression of L1 elements86.”

    From The role of retrotransposable elements in ageing and age-associated diseases (2021) · cites this paper as [86]

    The indexed copy (section labelled Abstract; page unavailable) describes genomic alterations in cancer, including somatic L1 insertions and a colorectal tumor with microsatellite instability. It also says DNA methylation suppresses TE RNA expression and is disrupted in cancers, but it does not report that L1 expression itself is increased in many cancer cases. Insertion frequency is not a measure of expression. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Multiple de novo somatic insertions and associated rearrangements have been identified in human cancers, in some cases numbering in the hundreds for an individual tumor.

    “Subsequent efforts identified multiple de novo somatic insertions and associated rearrangements in human cancers, in some cases numbering in the hundreds for an individual tumor86–89.”

    From The role of retrotransposable elements in ageing and age-associated diseases (2021) · cites this paper as [86]

    The passages labeled Abstract report 194 somatic transposable-element insertions across 43 patients, including 106 in one colorectal tumor (CR3518). That supports multiple insertions and a count exceeding one hundred in an individual tumor, but the paper does not report associated rearrangements; 106 also does not clearly support the plural phrasing “in the hundreds.” No page numbers are provided in our copy. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Genome sequencing approaches that revealed novel somatic LINE-1 integrations failed to find HERV integration consistent with re-infection.

    “Furthermore, genome sequencing approaches that have revealed novel somatic long interspersed nuclear element (LINE-1) integrations, failed to find HERV integration that would be consistent with re-infection 80.”
  • L1 activity has been implicated in a variety of age-related disorders, including cancer and neurodegeneration.

    “L1 activity has been implicated in a variety of age-related disorders12, including cancer7,13 and neurodegeneration14,15.”
  • The corrected RC-seq retrotransposition rate is consistent with the absence of significant somatic L1 insertions in brain tumors.

    “and is consistent with the absence of significant somatic L1 insertions in brain tumors (Helman et al., 2014; Iskow et al., 2010; Lee et al., 2012).”

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.
