A recent study conducted by the University of Rochester in New York investigates the long-term health effects of e-cigarette use, identifying potential dangers for users.

Published in the journal Scientific Reports, the study suggests that the mechanisms triggered by e-cigarettes may replicate those involved in cancer development.

The research points to the abnormal activity of microRNAs present in the blood of e-cigarette users as a contributing factor.

According to Dongmei Li, the lead researcher, "Exosomal microRNAs play a role in inflammation and pathological processes such as cancer.

These small molecules regulate gene expression and can activate or deactivate certain metabolic pathways in our cells.

Until now, we did not understand how vaping could affect them."

Furthermore, the study indicates that the epithelial cells lining the respiratory tract of e-cigarette users take significantly longer to regenerate and heal following injury compared to those who do not vape.

This delayed healing could have implications for lung health and recovery from respiratory conditions.

The research also elucidates the negative impact of e-cigarette vapor on cellular DNA, revealing that the vapor and its constituents can cause damage to genetic material.

Dr. Li noted that this foundational study on the hazards of vaping is expected to spur further research into the effects of e-cigarettes on exosomal microRNAs in plasma and other biological markers linked to cancer risk, enhancing the understanding of vaping toxicity.
