Abstract

Circadian clock genes are regulated by glucocorticoids; however, whether this regulation is a direct or secondary effect and the physiological consequences of this regulation were unknown. Here, we identified glucocorticoid response elements (GREs) at multiple clock genes and showed that 3 were directly regulated by the glucocorticoid receptor. We determined that a GRE within the core clock gene Per2 was continuously occupied during rhythmic expression and essential for glucocorticoid regulation of that gene in vivo. We further demonstrated that mice with a genomic deletion spanning this GRE expressed elevated leptin levels and were protected from glucose intolerance and insulin resistance on glucocorticoid treatment but not from muscle wasting. We conclude that Per2 is an integral component of a particular glucocorticoid regulatory pathway and that glucocorticoid regulation of the peripheral clock is selectively required for some actions of glucocorticoids.

  • Resetting of the peripheral clock occurs through molecular mechanisms involving direct interaction of glucocorticoids, glucocorticoid response elements and regulatory regions of core clock genes Bmal1, Cry1, Per1 and Per2.

    “Resetting of the peripheral clock occurs through well-defined molecular mechanisms that involve direct interaction of glucocorticoids, glucocorticoid response elements and the regulatory regions of core clock genes Bmal1, Cry1, Per1 and Per2 [63, 64].”

    From Sleep, testosterone and cortisol balance, and ageing men (2022) · cites this paper as [64]

    The Results report GR occupancy at response elements near Per1 and Per2 and identify them as direct GR targets involved in regulating the peripheral clock (page not provided). Bmal1 and Cry1 also showed glucocorticoid-stimulated oscillation, but the paper does not identify direct GR interaction with response elements at those genes; it reports that other clock genes did not change detectably in the early-response test. (LLM, conf=0.89)

  • Per2 null mice exhibit no glucocorticoid oscillations, indicating that PER2 may impact glucocorticoid receptor-dependent glucose metabolism.

    “Per2 null mice exhibit no glucocorticoid oscillations, indicating that PER2 may also impact glucocorticoid receptor (GR)-dependent glucose metabolism [24,25].”

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.
