Abstract

Glucocorticoid and other adipogenic hormones are secreted in mammals in circadian oscillations. Loss of this circadian oscillation pattern correlates with obesity in humans, raising the intriguing question of how hormone secretion dynamics affect adipocyte differentiation. Using live, single-cell imaging of the key adipogenic transcription factors CEBPB and PPARG, endogenously tagged with fluorescent proteins, we show that pulsatile circadian hormone stimuli are rejected by the adipocyte differentiation control system. In striking contrast, equally strong persistent signals trigger maximal differentiation. We identify the mechanism of how hormone oscillations are filtered as a combination of slow and fast positive feedback centered on PPARG. Furthermore, we confirm in mice that flattening of daily glucocorticoid oscillations significantly increases the mass of subcutaneous and visceral fat pads. Together, our study provides a molecular mechanism for why stress, Cushing's disease, and other conditions for which glucocorticoid secretion loses its pulsatility may lead to obesity.

  • A mathematical model linking the HPA and metabolic axes describes a way in which circadian glucocorticoid oscillations regulate a transcriptional circuit underlying adipocyte differentiation.

    “Similarly, a mathematical model linking the HPA and metabolic axes describes a way in which circadian glucocorticoid oscillations regulate a transcriptional circuit underlying adipocyte differentiation [84], suggesting mechanisms by which conditions that disrupt pulsatile glucocorticoid secretion could lead to obesity.”

  • Studies in mice demonstrate that abnormal glucocorticoid dynamics can increase the accumulation of fat mass.

    “Obesity is perhaps the best example of this, as studies in mice demonstrate that abnormal glucocorticoid dynamics can increase the accumulation of fat mass ( 67 ).”

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.
