Insights
Perinatal insults, such as disease or stress, can alter fetal development, leading to adult diseases. This review explores common outcomes and pathways, identifying research gaps in developmental programming.
Area of Science:
- Developmental biology
- Reproductive medicine
- Pathology
Background:
- Perinatal insults negatively impact fetal development, causing long-term health issues.
- Insults include maternal disease, nutrition, stress, environmental exposures, and medical interventions.
- These factors can lead to adult pathologies through altered developmental trajectories.
Purpose of the Study:
- To review insults contributing to developmental programming.
- To highlight common disease outcomes and converging mechanistic pathways.
- To identify knowledge gaps and future research directions in the field.
Main Methods:
- Literature review of studies on perinatal insults and developmental programming.
- Analysis of commonalities in disease outcomes across different insults.
- Examination of converging mechanistic pathways linking insults to pathologies.
- Identification of current knowledge gaps and future research priorities.
Main Results:
- Various perinatal insults converge on common mechanistic pathways.
- Diverse insults can lead to similar long-term detrimental outcomes and adult pathologies.
- Animal models are crucial for understanding underlying mechanisms of developmental programming.
Conclusions:
- Understanding the common pathways of developmental programming is key to preventing adult diseases.
- Further research is needed to address identified knowledge gaps.
- Interventions targeting perinatal insults hold promise for improving long-term health outcomes.
Abstract:
Accumulating evidence suggests that insults occurring during the perinatal period alter the developmental trajectory of the fetus/offspring leading to long-term detrimental outcomes that often culminate in adult pathologies. These perinatal insults include maternal/fetal disease states, nutritional deficits/excess, stress, lifestyle choices, exposure to environmental chemicals, and medical interventions. In addition to reviewing the various insults that contribute to developmental programming and the benefits of animal models in addressing underlying mechanisms, this review focuses on the commonalities in disease outcomes stemming from various insults, the convergence of mechanistic pathways via which various insults can lead to common outcomes, and identifies the knowledge gaps in the field and future directions.
