The omniscient placenta: Metabolic and epigenetic regulation of fetal programming

Open access
Nugent, Bridget M., Bale, Tracy L.·2015·Frontiers in Neuroendocrinology

Abstract

Fetal development could be considered a sensitive period wherein exogenous insults and changes to the maternal milieu can have long-term impacts on developmental programming. The placenta provides the fetus with protection and necessary nutrients for growth, and responds to maternal cues and changes in nutrient signaling through multiple epigenetic mechanisms. The X-linked enzyme O-linked-N-acetylglucosamine transferase (OGT) acts as a nutrient sensor that modifies numerous proteins to alter various cellular signals, including major epigenetic processes. This review describes epigenetic alterations in the placenta in response to insults during pregnancy, the potential links of OGT as a nutrient sensor to placental epigenetics, and the implications of placental epigenetics in long-term neurodevelopmental programming. We describe the role of placental OGT in the sex-specific programming of hypothalamic-pituitary-adrenal (HPA) axis programming deficits by early prenatal stress as an example of how placental signaling can have long-term effects on neurodevelopment.

  • In animal models, prenatal stress has been shown to lower expression of 11β-HSD2 mRNA and 11B-HSD2 activity, both of which are associated with increased 11β-HSD2 methylation in the placenta.

    “In animal models, prenatal stress has been shown to lower expression of 11β-HSD2 mRNA and 11B-HSD2 activity, both of which are associated with increased 11β-HSD2 methylation in the placenta 140 .”

    From Intergenerational transmission of trauma effects: putative role of epigenetic mechanisms (2018) · cites this paper as [140]

    Section 6.1 reports that prenatal stress decreases placental 11β-HSD2 mRNA in rats and that reduced expression is associated with increased promoter methylation. It also reports reduced 11β-HSD2 in female mouse placentas, but does not specify reduced enzyme activity or associate an activity measurement with methylation.

  • Fetal sex, or trophoblast cells from the embryo reflecting fetal sex, may differentially regulate epigenetic signals in the placenta, leading to differential signaling that feeds back to the offspring.

    “The importance of fetal sex, or more specifically, trophoblast cells from the embryo reflecting fetal sex, is that it may differentially regulate epigenetic signals in the placenta, leading to differential signaling that feeds back to the offspring 140”
  • The placenta is a central integrative organ because it senses and responds to maternal nutrients, hormones, inflammatory mediators and environmental agents through vascular, transport, endocrine and molecular functions.

    “The placenta is a central integrative organ because it senses and responds to maternal nutrients, hormones, inflammatory mediators and environmental agents through vascular, transport, endocrine and molecular functions [140,141,142].”
  • There are many reports of changes in placental DNA methylation and histone proteins in response to environmental cues that have been associated with developmental programming of the offspring.

    “Epigenetics is a rapidly expanding field, and there are now many reports of changes in placental DNA methylation and histone proteins in response to environmental cues that have been associated with developmental programming of the offspring (203, 417, 522).”

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.
