Insights
Perinatal stress disrupts offspring sexual development and behavior. This review explores toxicological impacts and epigenetic changes in response to early-life stress.
Area of Science:
- Reproductive biology
- Toxicology
- Epigenetics
Background:
- Perinatal stress negatively impacts offspring sexual differentiation and behavior across animal models.
- The underlying biochemical, cellular, genetic, and epigenetic mechanisms require further investigation.
Purpose of the Study:
- To review perinatal stressors as a toxicological phenomenon.
- To discuss recently characterized epigenetic responses to perinatal stress.
Main Methods:
- Literature review of studies on perinatal stress.
- Analysis of toxicological and epigenetic findings.
Main Results:
- Perinatal stress acts as a toxicological agent affecting development.
- Specific epigenetic modifications are identified as responses to stress.
Conclusions:
- Understanding epigenetic responses to perinatal stress is crucial for mitigating adverse developmental outcomes.
- Further research into these mechanisms can inform preventative strategies.
Introduction:
Numerous studies employing various animal models have found that perinatal stress, encountered in utero during sensitive developmental stages or shortly after birth, disrupts both sexual differentiation and sexual behavior in offspring. The biochemical, cellular, genetic and epigenetic events which are involved in the organismal response to perinatal stress are currently under investigation.
Methods, Results And Discussion:
In this review, the reader is introduced to perinatal stressors as a toxicological phenomenon, and several recently characterized epigenetic responses to said stressors are discussed.
