Air pollution exposure, specifically particulate matter (PM), alters epigenetic marks, increasing human disease risk. These epigenetic changes offer potential biomarkers and therapeutic targets for air pollution-related illnesses.
Area of Science:
- Environmental Health
- Molecular Biology
- Toxicology
Background:
- Airborne particulate matter (PM) exposure is a significant risk factor for human diseases.
- Epigenetic mechanisms, including DNA methylation, histone modifications, and non-coding RNAs, are implicated in environmental exposures and disease development.
Purpose of the Study:
- To review current studies on the relationship between epigenetic marks, air pollution exposure, and human health.
- To explore how air contaminants influence epigenetic mechanisms and alter epigenetic profiles.
- To identify the potential of epigenetic marks as biomarkers and therapeutic targets.
Main Methods:
- Literature review of existing studies on air pollution and epigenetics.
- Description of specific epigenetic mechanisms affected by air contaminants (DNA methylation, histone modifications, non-coding RNAs).
- Analysis of how environmental factors, including PM, influence these epigenetic mechanisms.
Main Results:
- Air pollution exposure alters epigenetic marks globally and at specific loci.
- Epigenetic changes induced by PM exposure increase susceptibility to human diseases.
- Air pollution is linked to increased mortality rates from non-accidental causes.
Conclusions:
- Epigenetic alterations are a key pathway through which particulate matter exposure impacts human health.
- Specific epigenetic marks show potential as biomarkers for air pollution exposure and related diseases.
- Further research is needed to elucidate unclear epigenetic mechanisms and identify novel therapeutic targets.

Background and Environment Affect 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...
