Summary
Prenatal exposure to environmental chemicals can disrupt the fetal epigenome, potentially leading to developmental disorders and diseases throughout life. Identifying these chemicals is crucial for health research and disease prevention.
Area of Science:
- Environmental health
- Epigenetics
- Developmental toxicology
Background:
- Prenatal exposure to environmental chemicals is widespread.
- The developing fetus, including primordial germ cells, embryo, and fetus, is particularly vulnerable to chemical exposures.
- Epigenetic dysregulation by environmental chemicals can have long-lasting health consequences.
Purpose of the Study:
- To review current evidence on how environmental chemicals affect the fetal epigenome.
- To highlight the potential consequences of prenatal epigenetic dysregulation on health outcomes.
- To discuss implications for risk assessment and disease prevention.
Main Methods:
- Literature review of recent scientific evidence.
- Synthesis of data on environmental contaminants and epigenetic alterations.
- Analysis of potential health impacts and risk assessment considerations.
Main Results:
- Diverse environmental chemicals can dysregulate the fetal epigenome.
- These epigenetic changes may lead to developmental disorders and diseases.
- Effects can manifest in childhood, across the lifespan, or even transgenerationally.
Conclusions:
- Prenatal epigenetic dysregulation by environmental chemicals poses significant health risks.
- Further research is needed on individual susceptibility and persistence of epigenetic alterations for formal risk assessment.
- Prioritizing the identification of such chemicals is essential for public health research and disease prevention.

01:20Gene-Environment Interactions
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...
01:46Epigenetic Regulation
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
01:37Epigenetic Regulation
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

02:30Genomic Imprinting and Inheritance
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

02:27Background and Environment Affect Phenotype
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
