Summary
Prenatal exposure to Bisphenol A (BPA), an endocrine disruptor, may cause lasting effects on brain, behavior, and immunity. These impacts are linked to epigenetic changes in offspring, with potential transgenerational implications.
Area of Science:
- Environmental Toxicology
- Developmental Biology
- Epigenetics
Background:
- Bisphenol A (BPA) is an estrogenic environmental toxin found in plastics with widespread human exposure.
- Concerns exist regarding its potential public health risks, particularly from in utero and early postnatal exposure.
- BPA exposure may lead to adverse effects on brain development, sexual differentiation, behavior, and immune function.
Purpose of the Study:
- To review research on prenatal Bisphenol A (BPA) exposure effects on brain, behavior, and immune outcomes.
- To discuss the role of epigenetic pathways in mediating these developmental effects.
- To explore the transgenerational implications of endocrine-disrupting chemical exposure.
Main Methods:
- Review of existing scientific literature on Bisphenol A (BPA) and its developmental and epigenetic effects.
- Analysis of studies investigating molecular mechanisms, including DNA methylation and gene expression changes.
- Examination of correlations between epigenetic alterations, gene expression, and phenotypic outcomes.
Main Results:
- Maternal BPA exposure can lead to postnatal changes in DNA methylation and altered gene expression in offspring.
- Evidence suggests BPA exposure has consequences for brain development, behavior, and immune function.
- Epigenetic mechanisms are implicated in mediating the long-lasting effects of BPA.
Conclusions:
- Prenatal Bisphenol A (BPA) exposure can induce developmental effects mediated by epigenetic pathways.
- Further research is needed to link BPA-induced epigenetic changes to specific genes, tissues, and phenotypic outcomes.
- Understanding these effects is crucial for assessing the transgenerational risks of endocrine-disrupting chemicals.

Epigenetic Regulation
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
Epigenetic 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.

Genomic 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.

Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Background 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...

Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
