Abstract

The H19 locus belongs to a cluster of imprinted genes that is linked to the human Beckwith-Wiedemann syndrome. The expression of H19 and its closely associated IGF2 gene is frequently deregulated in some human tumors, such as Wilms' tumors. In these cases, biallelic IGF2 expression and lack of expression of H19 are associated with hypermethylation of the imprinting center of this locus. These observations and others have suggested a potential tumor suppressor effect of the H19 locus. Some studies have also suggested that H19 is an oncogene, based on tissue culture systems. We show, using in vivo murine models of tumorigenesis, that the H19 locus controls the size of experimental teratocarcinomas, the number of polyps in the Apc murine model of colorectal cancer and the timing of appearance of SV40-induced hepatocarcinomas. The H19 locus thus clearly displays a tumor suppressor effect in mice.

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.
