Maternal corticosterone regulates nutrient allocation to fetal growth in mice

Abstract

Key points: Stress during pregnancy leads to fetal growth restriction. Natural glucocorticoids, such as corticosterone, are elevated by maternal stress and, hence, may mediate the effects of stress on fetal growth. This study shows that increasing corticosterone levels in pregnant mice limits fetal growth by reducing the amino acid supply and density of blood vessels in the placenta. The findings suggest that excess corticosterone may act to defend maternal resources during times of stress by constraining the placental allocation of nutrients to the fetus. The results also provide a potential mechanism by which stresses during pregnancy can program intrauterine growth and development with consequences in later life. Abstract Stresses during pregnancy that increase maternal glucocorticoids reduce birth weight in several species. However, the role of natural glucocorticoids in the mother in fetal acquisition of nutrients for growth remains unknown. This study aimed to determine whether fetal growth was reduced as a consequence of altered amino acid supply when mice were given corticosterone in their drinking water for 5 day periods in mid to late pregnancy (day, D, 11–16 or D14–19). Compared to controls drinking tap water, fetal weight was always reduced by corticosterone. At D16, corticosterone had no effect on materno‐fetal transfer of [ 14 C]methylaminoisobutyric acid (MeAIB), although placental MeAIB accumulation and expression of the Slc38a1 and Slc38a2 transporters were increased. However, at D19, 3 days after treatment ended, materno‐fetal transfer of MeAIB was increased by 37% ( P < 0.04). During treatment at D19, placental accumulation and materno‐fetal transfer of MeAIB were reduced by 40% ( P < 0.01), although expression of Slc38a1 was again elevated. Permanent reductions in placental vascularity occurred during the earlier but not the later period of treatment. Placental Hsd11b2 expression, which regulates feto‐placental glucocorticoid bioavailability, was also affected by treatment at D19 only. Maternal corticosterone concentrations inversely correlated with materno‐fetal MeAIB clearance and fetal weight at D19 but not D16. On D19, weight gain of the maternal carcass was normal during corticosterone treatment but reduced in those mice treated from D11 to D16, in which corticosterone levels were lowest. Maternal corticosterone is, therefore, a physiological regulator of the amino acid supply for fetal growth via actions on placental phenotype.

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.
