Abstract

p53 is critical in regulating the differentiation of ES and induced pluripotent stem (iPS) cells. Here, we report a whole-genome study of p53-mediated DNA damage signaling in mouse ES cells. Systems analyses reveal that binding of p53 at the promoter region significantly correlates with gene activation but not with repression. Unexpectedly, we identify a regulatory mode for p53-mediated repression through interfering with distal enhancer activity. Importantly, many ES cell-enriched core transcription factors are p53-repressed genes. Further analyses demonstrate that p53-repressed genes are functionally associated with ES/iPS cell status while p53-activated genes are linked to differentiation. p53-activated genes and -repressed genes also display distinguishable features of expression levels and epigenetic markers. Upon DNA damage, p53 regulates the self-renewal and pluripotency of ES cells. Together, these results support a model where, in response to DNA damage, p53 affects the status of ES cells through activating differentiation-associated genes and repressing ES cell-enriched genes.

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.
