Abstract

muREC2/RAD51L1 is a radiation-inducible gene that regulates cell cycle progression. To elucidate the biological function of muREC2/RAD51L1, the gene was disrupted in embryonic stem cells by homologous recombination. Mice heterozygous for muREC2/RAD51L1 appear normal and fertile; however, no homozygous pups were born after interbreeding of heterozygous mice. Timed pregnancy studies showed that homozygous mutant embryos were severely retarded in growth as early as ca. 5 days gestation (E5.5) and were completely resorbed by E8.5. Mutant blastocyst outgrowth was also severely impaired in a double-knockout embryo, but embryonic development did progress further in a p53-null background. These results suggest that muREC2/RAD51L1 plays a role in cell proliferation and early embryonic development, perhaps through interaction with p53.

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.
