Abstract

Hypothalamo-pituitary-adrenal axis secretory responses to stress were compared in female virgin, late pregnant, parturient, and lactating mice. The basal plasma ACTH concentration was not different in pregnancy or lactation compared with virgins, but corticosterone concentration and corticosteroid-binding globulin capacity were greatly elevated in late pregnancy. Secretory responses to novel environment were attenuated in pregnant, but not lactating, mice compared with virgin females, whereas ACTH responses to forced swimming were attenuated in both groups. The expression of immediate early gene (nur77) mRNA increased in paraventricular nucleus neurons after stress exposure in virgin and lactating, but not pregnant, mice. During parturition, the basal ACTH concentration was similar to virgin and pregnant controls and did not increase with stress. Oxytocin secretion in response to either novel environment or forced swimming was unchanged in any reproductive group, whereas vasopressin secretion was decreased by both stressors, but only in virgins. Pretreatment with oxytocin receptor antagonist centrally had no effect on ACTH responses to stress in either virgin or pregnant mice. Pretreatment with an opioid receptor antagonist increased ACTH responses to stress in virgin mice, indicating opioid inhibition, but had no effect in pregnancy. Thus, in mice hypothalamo-pituitary-adrenal hyporesponsiveness in late pregnancy is a consequence of reduced responsiveness of paraventricular neurons, but inhibition by opioids or intracerebral oxytocin does not appear to be involved.

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.
