A comprehensive analysis of 78 genes related to epigenetic pathways (i.e., DNA-methylation and post-translational histone modifications) was performed.

Examination of the SM exposed human skin samples also revealed a significant increase of global DNA methylation in vivo, underlining the biological relevance of our findings. Thus, we demonstrated for the first time that SM affects epigeneticpathways and causes epigenetic modulations both in vivo and in vitro.",
