Epimutational effects of electronic cigarettes.

Area of Science:

• Environmental Health
• Toxicology
• Epigenetics

Background:

• Electronic cigarettes (e-cigarettes) are often perceived as less harmful than conventional cigarettes (c-cigarettes) due to the absence of tobacco combustion.
• Emerging research indicates that e-cigarette aerosols contain toxic compounds and can negatively impact the human epigenome.

Purpose of the Study:

• To review recent findings on the epigenetic outcomes associated with e-cigarette aerosol exposure.
• To discuss the impact of common e-cigarette ingredients on epigenetic mechanisms.

Main Methods:

• Literature review of recent studies on e-cigarette aerosols and epigenetic effects.
• Analysis of the effects of specific e-cigarette components on DNA methylation, histone modifications, and noncoding RNA expression.

Main Results:

• E-cigarette aerosols contain numerous toxic compounds.
• Exposure to e-cigarette aerosols adversely affects the human epigenome, including DNA methylation, histone modifications, and noncoding RNA expression.
• Typical e-cigarette ingredients like nicotine and volatile organic compounds contribute to these epigenetic changes.

Conclusions:

• E-cigarette use poses potential epigenotoxicity risks to the human body.
• The observed epigenetic alterations may contribute to the development of diseases linked to e-cigarette use.
• Inhaling e-cigarette aerosols carries health risks comparable to conventional cigarettes due to potential epigenotoxicity.
