Rhythmic histone acetylation underlies transcription in the mammalian circadian clock

Abstract

In the mouse circadian clock, a transcriptional feedback loop is at the centre of the clockwork mechanism. Clock and Bmal1 are essential transcription factors that drive the expression of three period genes (Per1-3) and two cryptochrome genes (Cry1 and Cry2). The Cry proteins feedback to inhibit Clock/Bmal1-mediated transcription by a mechanism that does not alter Clock/Bmal1 binding to DNA. Here we show that transcriptional regulation of the core clock mechanism in mouse liver is accompanied by rhythms in H3 histone acetylation, and that H3 acetylation is a potential target of the inhibitory action of Cry. The promoter regions of the Per1, Per2 and Cry1 genes exhibit circadian rhythms in H3 acetylation and RNA polymerase II binding that are synchronous with the corresponding steady-state messenger RNA rhythms. The histone acetyltransferase p300 precipitates together with Clock in vivo in a time-dependent manner. Moreover, the Cry proteins inhibit a p300-induced increase in Clock/Bmal1-mediated transcription. The delayed timing of the Cry1 mRNA rhythm, relative to the Per rhythms, is due to the coordinated activities of Rev-Erbalpha and Clock/Bmal1, and defines a new mechanism for circadian phase control.

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?

  • Core clock genes undergo rhythmic H3 histone acetylation, which can be explained by the rhythmic interaction of p300 with CLOCK.

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.
