Inactivation of the Retinoblastoma Susceptibility Gene in Human Breast Cancers

Abstract

Mutational inactivation of the retinoblastoma susceptibility (RB) gene, a recessive cancer gene, has been implicated in the genesis of retinoblastoma and certain other human neoplasms. This gene is now shown to be inactivated in two of nine human breast cancer cell lines examined. The RB gene of one cell line had a homozygous internal duplication of a 5-kilobase region containing exons 5 and 6. The RB messenger RNA transcript was correspondingly lengthened, and its translation was probably terminated prematurely due to a shifted reading frame. The other cell line had a homozygous deletion of the RB gene that removed the entire gene beyond exon 2. The RB gene product, pp110 RB , was not detectable in either cell line by immunoprecipitation with specific antibodies. These findings are significant in relation to proposed genetic mechanisms of breast cancer formation.

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.
