Abstract

The ability to determine the global location of transcription factor binding sites in vivo is important for a comprehensive understanding of gene regulation in human cells. We have developed a technology, called serial analysis of binding elements (SABE), involving subtractive hybridization of chromatin immunoprecipitation-enriched DNA fragments followed by the generation and analysis of concatamerized sequence tags. We applied the SABE technology to search for p53 target genes in the human genome, and have identified several previously described p53 targets in addition to numerous potentially novel targets, including the DNA mismatch repair genes MLH1 and PMS2 . Both of these genes were determined to be responsive to DNA damage and p53 activation in normal human fibroblasts, and have p53-response elements within their first intron. These two genes may serve as a sensor in DNA repair mechanisms and a critical determinant for the decision between cell-cycle arrest and apoptosis. These results also demonstrate the potential for use of SABE as a broadly applicable means to globally identify regulatory elements for human transcription factors in vivo .

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • PMS2 and MLH1 were believed to be p53-activated targets, but meta-analysis data show this unlikely.

    “The DNA repair genes PMS2 and MLH1 were also believed to be p53-activated targets,175 but meta-analysis data show this unlikely to be the case18 (Supplementary Table S2).”

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.
