Abstract

The tumor suppressor proteins p16 INK4A and p14 ARF, encoded by the INK4A–ARF locus, are key regulators of cellular senescence. The locus is epigenetically silenced by the repressive H3K27me3 mark in normally growing cells, but becomes activated in response to oncogenic stress. Here, we show that expression of the histone H3 Lys 27 (H3K27) demethylase JMJD3 is induced upon activation of the RAS–RAF signaling pathway. JMJD3 is recruited to the INK4A–ARF locus and contributes to the transcriptional activation of p16 INK4A in human diploid fibroblasts. Additionally, inhibition of Jmjd3 expression in mouse embryonic fibroblasts results in suppression of p16 Ink4a and p19 Arf expression and in their immortalization.

  • Oncogene activation induces JMJD3, which removes repressive H3K27 tri-methylation marks and thereby promotes p16 expression.

    “For example, oncogene activation induces the expression of the histone 3 Lys27 (H3K27) demethylase, Jumonji domain-containing D3 (JMJD3), which removes the repressive H3K27 tri-methylation marks and thereby promotes p16 expression [19].”
  • During senescence, PRC delocalization from the CDKN2A locus, transcriptional downregulation of EZH2, and recruitment of JMJD3 lead to removal of the repressive H3K27me3 mark at the CDKN2A locus and facilitate p16 transcription.

    “During senescence, PRC delocalization from the CDKN2A locus, transcriptional downregulation of EZH2 [83], and recruitment of JMJD3 [84,85], a histone lysine demethylase that catalyzes H3K27 demethylation, lead to removal of the repressive H3K27me3 mark at the CDKN2A locus and facilitate p16 transcription.”

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.
