Abstract

Background Traumatic experiences in early life are risk factors for the development of behavioral and emotional disorders. Such disorders can persist through adulthood and have often been reported to be transmitted across generations.Methods To investigate the transgenerational effect of early stress, mice were exposed to chronic and unpredictable maternal separation from postnatal day 1 to 14.Results We show that chronic and unpredictable maternal separation induces depressive-like behaviors and alters the behavioral response to aversive environments in the separated animals when adult. Most of the behavioral alterations are further expressed by the offspring of males subjected to maternal separation, despite the fact that these males are reared normally. Chronic and unpredictable maternal separation also alters the profile of DNA methylation in the promoter of several candidate genes in the germline of the separated males. Comparable changes in DNA methylation are also present in the brain of the offspring and are associated with altered gene expression.Conclusions These findings highlight the negative impact of early stress on behavioral responses across generations and on the regulation of DNA methylation in the germline.

  • Multigenerational early-life stress models demonstrate enduring regulatory and behavioral variation, including depressive-like behaviors and altered responses to environmental novelty.

    “Multigenerational early-life stress models demonstrate enduring regulatory and behavioral variation, including depressive-like behaviors and altered responses to environmental novelty (64).”
  • These findings include epigenetic modulation of genes involved in synaptic and stress signaling, including Mecp2, CB1, and CRFR2, with methylation differences observed in both germline and neural tissues.

  • Enduring behavioral responses to stress and epigenetic alterations in adult offspring have been demonstrated to be mediated by changes in gametes, in utero effects, variations in early postnatal care, and/or other early life experiences influenced by parental exposure.

    “Enduring behavioral responses to stress and epigenetic alterations in adult offspring have been demonstrated to be mediated by changes in gametes (10)(11)(12)(13), in utero effects (14), variations in early postnatal care (15,16), and/or other early life experiences (17) that are influenced by parental exposure (18).”
  • Epigenetic effects in maternal or paternal gametes are a potential explanation for epigenetic effects in offspring, but blood samples will not permit ascertainment of gamete-dependent transmission.

    “Epigenetic effects in maternal or paternal gametes are a potential explanation for epigenetic effects in offspring (10-13), but blood samples will not permit ascertainment of gamete-dependent transmission.”
  • Early-life postnatal adversity in animal models can persistently affect behavior across generations and DNA methylation in the germline.

    “early-life postnatal adversity in animal models can persistently affect behavior across generations and DNA methylation in the germline.”

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.
