Abstract EN
It remains unknown whether tobacco smoke induces DNA hypermethylation as an early event in carcinogenesis or as a late event, specific to overt cancer tissue.
Using MethyLight assays, we analyzed 316 lung tissue samples from 151 cancer-free subjects (121 ever-smokers and 30 never-smokers) for hypermethylation of 19 genes previously observed to be hypermethylated in nonsmall cell lung cancers.
Only APC (39%), CCND2 (21%), CDH1 (7%), and RARB (4%) were hypermethylated in >2% of these cancer-free subjects.
CCND2 was hypermethylated more frequently in ever-smokers (26%) than in never-smokers (3%).
CCND2 hypermethylation was also associated with increased age and upper lobe sample location.
APC was frequently hypermethylated in both ever-smokers (41%) and never-smokers (30%).
BVES, CDH13, CDKN2A (p16), CDKN2B, DAPK1, IGFBP3, IGSF4, KCNH5, KCNH8, MGMT, OPCML, PCSK6, RASSF1, RUNX, and TMS1 were rarely hypermethylated (<2%) in all subjects.
Hypermethylation of CCND2 may reflect a smoking-induced precancerous change in the lung.
