Abstract

Prenatal stress is associated with an increased vulnerability to neurodevelopmental disorders, including autism and schizophrenia. To determine the critical time window when fetal antecedents may induce a disease predisposition, we examined behavioral responses in offspring exposed to stress during early, mid, and late gestation. We found that male offspring exposed to stress early in gestation displayed maladaptive behavioral stress responsivity, anhedonia, and an increased sensitivity to selective serotonin reuptake inhibitor treatment. Long-term alterations in central corticotropin-releasing factor (CRF) and glucocorticoid receptor (GR) expression, as well as increased hypothalamic–pituitary–adrenal (HPA) axis responsivity, were present in these mice and likely contributed to an elevated stress sensitivity. Changes in CRF and GR gene methylation correlated with altered gene expression, providing important evidence of epigenetic programming during early prenatal stress. In addition, we found the core mechanism underlying male vulnerability may involve sex-specific placenta responsivity, where stress early in pregnancy significantly increased expression of PPARα (peroxisome proliferator-activated receptor α), IGFBP-1 (insulin-like growth factor binding protein 1), HIF3α (hypoxia-inducible factor 3a), and GLUT4 (glucose transporter 4) in male placentas but not females. Examination of placental epigenetic machinery revealed basal sex differences, providing further evidence that sex-specific programming begins very early in pregnancy, and may contribute to the timing and vulnerability of the developing fetus to maternal perturbations. Overall, these results indicate that stress experience early in pregnancy may contribute to male neurodevelopmental disorders through impacts on placental function and fetal development.

  • In animal models of prenatal stress, exposure to chronic stress in utero increased male, but not female, HPA stress reactivity.

    From Intergenerational transmission of trauma effects: putative role of epigenetic mechanisms (2018) · cites this paper as [159]

    The Prenatal Stress Methods describe chronic variable stress during gestation, and the HPA Axis Stress Response Results report elevated corticosterone after restraint in males exposed to stress early in gestation. The Discussion reports altered tail-suspension behavior in males but not females; however, HPA-axis reactivity was measured only in males, so the source does not establish that female HPA reactivity was unchanged. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Early gestational stress exposure led to sex differences in expression and methylation of genes in the placenta associated with growth and nutrient transport.

    “early gestational stress exposure led to sex differences in expression and methylation of genes in the placenta associated with growth and nutrient transport 159”

    From Intergenerational transmission of trauma effects: putative role of epigenetic mechanisms (2018) · cites this paper as [159]

    The Results section reports sex-specific changes in placental expression of genes associated with growth and nutrient transport after early prenatal stress. It also reports changes in expression of the methylation-maintenance enzyme DNMT1, but does not report methylation changes in those placental genes themselves (page numbers unavailable in our copy). (LLM, conf=0.90)

  • Among mice exposed to stress during early, mid and late gestation, male F1 with early gestation prenatal stress exposure demonstrated behavioral indicators of stress responsivity and anhedonia, as well as alterations in GR and CRF expression and increased HPA axis responsivity, with corresponding alteration in CRF and nr3c1 gene methylation.

  • These behaviors were transmitted to the next generation through the male germ line.

    From Intergenerational transmission of trauma effects: putative role of epigenetic mechanisms (2018) · cites this paper as [159]

    The Materials and Methods section reports depressive-like behaviors in male offspring exposed to stress during gestation. Neither that section nor the Results and Discussion passages establish transmission to another generation through the male germ line; searches for germline, sperm, paternal inheritance, and F2 offspring found no such evidence. Page numbers were not available in our copy. (LLM, conf=0.76)

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.
