Differentiating vaping from smoking through epigenetic and transcriptomic markers
Official title: Differentiating the biological effects of vaping from smoking by analyzing the methylome and transcriptome
Funded at University of Southern California · NIH-11348860 · Data updated 2026-11-12
This study looks at adults who vape or smoke to identify specific DNA methylation and gene expression changes that distinguish vaping from smoking, with the goal of finding biomarkers tied to health risks.

Who could benefit from this research
✓Could help
Adults 21+ who are current vapers, current smokers, or non-users, with no acute illnesses.
✕Less likely to help
Individuals under 21 or those not using tobacco products may not directly benefit from this study.
What this research studies
Researchers will compare epigenetic marks and RNA profiles in cells and tissues from healthy adult vapers, smokers, and non-users to separate the effects of vaping from smoking. The study will examine how exposure amount and duration, as well as different device features and cigarette types, influence these molecular changes. By linking molecular patterns to disease risk, the project aims to identify biomarkers of exposure and effect that could improve health risk assessments. The work will help clarify whether vaping poses distinct or similar risks compared to traditional smoking, informing patients about potential long-term health implications.
Why it matters
Potential benefit: If successful, patients could benefit from clearer biomarkers that help assess personal health risks related to vaping versus smoking.
How similar studies have gone: Previous work has shown that smoking and vaping can leave distinct epigenetic and transcriptomic signatures, supporting this approach.
