Abstract

We tested the hypothesis that in primates, maternal melatonin restrains fetal and newborn adrenal cortisol production. A functional G‐protein‐coupled MT1 membrane‐bound melatonin receptor was detected in 90% gestation capuchin monkey fetal adrenals by (a) 2‐[125 I] iodomelatonin binding (Kd, 75.7 ± 6.9 p m; Bmax, 2.6 ± 0.4 fmol (mg protein)−1), (b) cDNA identification, and (c) melatonin inhibition of adrenocorticotrophic hormone (ACTH)‐ and corticotrophin‐releasing hormone (CRH)‐stimulated cortisol but not of dehydroepiandrosterone sulphate (DHAS) production in vitro. Melatonin also inhibited ACTH‐induced 3β‐hydroxysteroid dehydrogenase mRNA expression. To assess the physiological relevance of these findings, we next studied the effect of chronic maternal melatonin suppression (induced by exposure to constant light during the last third of gestation) on maternal plasma oestradiol during gestation and on plasma cortisol concentration in the 4‐ to 6‐day‐old newborn. Constant light suppressed maternal melatonin without affecting maternal plasma oestradiol concentration, consistent with no effect on fetal DHAS, the precursor of maternal oestradiol. However, newborns from mothers under constant light condition had twice as much plasma cortisol as newborns from mothers maintained under a normal light–dark schedule. Newborns from mothers exposed to chronic constant light and daily melatonin replacement had normal plasma cortisol concentration. Our results support a role of maternal melatonin in fetal and neonatal primate cortisol regulation.

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.
