Abstract

Cells respond to DNA damage by activating both cellular growth arrest and DNA repair processes. In Saccharomyces cerevesiae the RAD9 gene controls DNA damage-mediated cell cycle arrest that is known to allow efficient repair. To ascertain whether RAD9 plays a role in DNA repair per se, the removal of UV-induced photolesions was assessed in synchronized isogenic normal and rad9 cells using the high resolution primer extension technique. The results show that RAD9 is indeed involved in the removal of photolesions from both the transcribed and the non-transcribed strands of the reporter GAL10 gene, in G(1)- as well as G(2)/M-arrested cells. Interestingly, these data also reveal that in both normal and rad9 mutant, the repair strand bias towards the transcribed stand is more pronounced in G(2)/M- than in G(1)-arrested cells. These data indicate that RAD9 coordinate the cellular response to DNA damage by activating both cell cycle checkpoint and excision repair.

  • S. cerevisiae Rad9 plays a role in repair of both UV-damaged strands of an actively transcribed gene, likely indirectly through up-regulation of NER genes RAD2, RAD7, RAD16, and RAD23.

    “The S. cerevisiae Rad9 gene product plays a role in the repair of both UV-damaged strands of an actively transcribed gene; this effect on NER is likely indirect and probably occurs through up-regulation of some NER genes (i.e., RAD2, RAD7, RAD16 and RAD23), consistently with a previously reported Rad9-dependent stimulation of NER genes transcription [98].”

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.
