Abstract

Increased 4N (G2/tetraploid) cell populations have been postulated to be genetically unstable intermediates in the progression to many cancers, but the mechanism by which they develop and their relationship to instability have been difficult to investigate in humans in vivo. Barrett's esophagus is an excellent model system in which to investigate the order in which genetic and cell cycle abnormalities develop relative to each other during human neoplastic progression. Neoplastic progression in Barrett's esophagus is characterized by inactivation of the p53 gene, the development of increased 4N (G2/tetraploid) cell fractions, and the appearance of aneuploid cell populations. We investigated the hypothesis that patients whose biopsies have increased 4N (G2/tetraploid) cell fractions are predisposed to progression to aneuploidy and determined the relationship between inactivation of p53 and the development of 4N abnormalities in Barrett's epithelium. Our results indicate that increased 4N (G2/tetraploid) populations predict progression to aneuploidy and that the development of 4N abnormalities is interdependent with inactivation of the p53 gene in Barrett's esophagus in vivo.

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.
