Global loss of DNA methylation and locus/gene-specific gain of DNA methylation are two distinct hallmarks of carcinogenesis. Aberrant DNA methylation is implicated in smoking-related lung cancer. In this study, we have comprehensively investigated the modulation of DNA methylation consequent to chro...

Methylated genomic fragments from tumor DNA and matching normal control were enriched with the methylated-CpG island recovery assay (MIRA); amplified, labeled and hybridized on Agilent CpG island tiling oligo arrays. MIRA enriched samples from tumor were labeled with Cy5 while MIRA enriched DNA samp...

A large body of evidence has linked secondhand smoke (SHS) to lung cancer in nonsmokers. Yet, the underlying mechanisms of SHS carcinogenicity in nonsmokers' lung cancer remain elusive. Recently, we have demonstrated a genotoxic mode of action for SHS, based on the ability of this carcinogen to indu...
