Abstract

Studies on glucocorticoid receptor (GR) action typically assess gene responses by long-term stimulation with synthetic hormones. As corticosteroids are released from adrenal glands in a circadian and high-frequency (ultradian) mode, such treatments may not provide an accurate assessment of physiological hormone action. Here we demonstrate that ultradian hormone stimulation induces cyclic GR-mediated transcriptional regulation, or gene pulsing, both in cultured cells and in animal models. Equilibrium receptor-occupancy of regulatory elements precisely tracks the ligand pulses. Nascent RNA transcripts from GR-regulated genes are released in distinct quanta, demonstrating a profound difference between the transcriptional programs induced by ultradian and constant stimulation. Gene pulsing is driven by rapid GR exchange with response elements and by GR recycling through the chaperone machinery, which promotes GR activation and reactivation in response to the ultradian hormone release, thus coupling promoter activity to the naturally occurring fluctuations in hormone levels. The GR signalling pathway has been optimized for a prompt and timely response to fluctuations in hormone levels, indicating that biologically accurate regulation of gene targets by GR requires an ultradian mode of hormone stimulation.

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

  • A high proportion of patients on conventional corticosteroid replacement therapy for adrenal insufficiency are overtreated or on inappropriate replacement regimens.

    “A high proportion of patients on “conventional” corticosteroid replacement therapy for AI are over treated or on inappropriate replacement regimens (120).”

    From Hormonal Replacement in Hypopituitarism in Adults: An Endocrine Society Clinical Practice Guideline (2016) · cites this paper as [120]

    The Discussion says corticosteroid replacement regimens for patients with hypocortisolaemia lack effective ultradian rhythmicity, which supports a concern about how replacement is administered. It does not say that a high proportion of patients are overtreated or quantify how many receive inappropriate regimens. (LLM, conf=0.84)

  • Ultradian hormone stimulation induces glucocorticoid receptor-mediated pulses of gene transcription.

    “For instance, ultradian hormone stimulation is known to induce glucocorticoid receptor-mediated pulses of gene transcription [78], and there exists a growing realisation that understanding how the dynamics of glucocorticoid signalling affects gene regulation is key to the design of effective chronotherapies 79, 80.”

    From Mathematical Modelling of Endocrine Systems (2019) · cites this paper as [78]

  • Glucocorticoid responsive genes respond to rapid fluctuations in glucocorticoid levels in a biologically meaningful way.

    “it is now clear that glucocorticoid responsive genes respond to these rapid fluctuations in a biologically meaningful way.”

    From Origin of ultradian pulsatility in the hypothalamic–pituitary–adrenal axis (2010) · cites this paper as Stavreva et al. 2009

  • The physiological response to "clamped" cortisol levels may differ from ultradian rhythm.

    “This suggests that acute diurnal variation in cortisol concentrations may not substantially alter lipolysis during normal physiology, although the physiological response to “clamped” cortisol levels may differ from ultradian rhythm.34”
  • Very few studies have assessed the impact of glucocorticoid dose optimization on markers of bone formation and resorption.

    “Very few studies have assessed the impact of GC dose optimization on markers of bone formation and resorption (120).”

    From Hormonal Replacement in Hypopituitarism in Adults: An Endocrine Society Clinical Practice Guideline (2016) · cites this paper as [120]

    The Discussion addresses glucocorticoid treatment timing and its possible side effects, but not how many studies have assessed dose optimization. Searches for bone formation, bone resorption, and dose optimization found no passage about bone-turnover markers in our copy. (LLM, conf=0.76)

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.
