Abstract

Diet during pregnancy influences the future health of a woman's offspring, with outcomes differing depending on the child's sex. Because the placenta buffers the fetus from the mother, we examined the impact of diet and fetal sex on placental gene expression in mice fed either a very-high-fat, low-fat, chow diet of intermediate caloric density. At day 12.5 of pregnancy, placental RNA was extracted and analyzed by microarray. The expression of 1,972 genes was changed more than 2-fold ( P < 0.05) in comparisons across diet in at least one of the three groups. Female placentae demonstrated more striking alterations in gene expression in response to maternal diet than male placentae. Notably, each diet provided a distinctive signature of sexually dimorphic genes, with expression generally higher in genes (651 out of 700) from female placentae than those from male placentae. Several genes normally considered as characteristic of kidney function were affected by diet, including genes regulating ion balance and chemoreception. The placenta also expressed most of the known olfactory receptor genes ( Olfr ), which may allow the placenta to sense odorant molecules and other minor dietary components, with transcript levels of many of these genes influenced by diet and fetal sex. In conclusion, gene expression in the murine placenta is adaptive and shaped by maternal diet. It also exhibits pronounced sexual dimorphism, with placentae of females more sensitive to nutritional perturbations than placentae of males.

  • Sex-dependent differences in gene expression are likely to underlie the contrasting placental responses observed following exposure to high-fat/low-fat diets, glucocorticoids, or hypoxia in mice.

    “Nonetheless, sex-dependent differences in gene expression are likely to underlie the contrasting placental responses observed following exposure to high-fat/low-fat diets (202, 356), glucocorticoids (132), or hypoxia (133, 363) in mice.”

  • In the mouse, manipulation of dietary fat content during pregnancy alters expression of both the growth hormone gene (Gh1) and the extensive family of prolactin and prolactin-like genes in the placenta during late gestation.

    “In the mouse, manipulation of dietary fat content during pregnancy also alters expression of both the growth hormone gene (Gh1) and the extensive family of prolactin and prolactin-like genes in the placenta during late gestation (356).”

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.
