Frequent inactivation of the retinoblastoma anti-oncogene is restricted to a subset of human tumor cells.
Open accessAbstract
We have used polyclonal anti-synthetic peptide serum to study the role of retinoblastoma gene (RB) inactivation in a variety of human tumor cell lines. Our analysis indicates that inactivation of the RB protein, p105-Rb, is universal in retinoblastoma cells, vindicating the predictions of the Knudson "two-hit" hypothesis. In addition, our analysis has shown that inactivations of the RB gene are nearly as frequent in a more common human tumor, small cell lung carcinoma. One-third of bladder carcinomas surveyed also carry altered or absent p105-Rb. Other human tumors by contrast demonstrate only infrequent inactivation of the RB gene. These results suggest that inactivation of the RB gene is a critical step in the pathogenesis of a subset of human tumors.

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.
