E-cigarette flavor and device type play a key role in vaping-related molecular changes, study finds<\/h1>\n\n\n<\/div>\n \n \n

Researchers from the Keck School of Medicine of USC compared changes in gene expression among vapers, smokers and non-users to investigate molecular pathways linked to cancer and other diseases.<\/p>\n\n\n\n<\/div>\n \n

People who vape regularly show altered activity in 3,124 genes across the genome compared with people who do not smoke or vape. While some of those changes (28.8%) relate to how often or how much people vape, a much greater portion (66.6%) is linked to the type of flavors and devices they use. The findings, just published in the journal <\/span>Frontiers in Oncology<\/span><\/a>, underscore the role of flavor and device type in the biological effects of vaping and could have regulatory implications as the Food and Drug Administration (FDA) moves to approve marketing of flavored vapes.<\/span><\/p>\n
