abstract = {Tobacco use is a major modifiable risk factor for adverse
health outcomes, including cancer, and elicits profound
epigenetic changes thought to be associated with long-term
cancer risk. While electronic cigarettes (e-cigarettes) have
been advocated as harm reduction alternatives to tobacco
products, recent studies have revealed potential detrimental
effects, highlighting the urgent need for further research
into the molecular and health impacts of e-cigarettes. Here,
we applied computational deconvolution methods to dissect
the cell- and tissue-specific epigenetic effects of tobacco
or e-cigarette use on DNA methylation (DNAme) in over 3,500
buccal/saliva, cervical, or blood samples, spanning
epithelial and immune cells at directly and indirectly
exposed sites. The 535 identified smoking-related DNAme loci
(CpGs) clustered into four functional groups, including
detoxification or growth signaling, based on cell type and
anatomical site. Loci hypermethylated in buccal epithelial
cells of smokers associated with NOTCH1/RUNX3/growth factor
receptor signaling also exhibited elevated methylation in
cancer tissue and progressing lung carcinoma in situ
lesions, and hypermethylation of these sites predicted lung
cancer development in buccal samples collected from smokers
up to 22 years prior to diagnosis, suggesting a potential
role in driving carcinogenesis. Alarmingly, these CpGs were
also hypermethylated in e-cigarette users with a limited
smoking history. This study sheds light on the cell
type-specific changes to the epigenetic landscape induced by
smoking-related products.},
