À la recherche du temps perdu: Smoking and Genomic Imprinting

Tobacco smoking is the largest cause of preventable mortality and morbidity in the United States. Many of the pathological consequences of smoking result from mutations, but gene expression can also be modulated by genomic imprinting mediated by DNA methylation-so-called "epigenetic" regulation. Since genomic imprints, unlike gene mutations, can be reversed, it is of great interest what smoking-related imprints mean for smoking-related pathologies in smokers and their children, and the potential for imprint-targeted diagnostics and therapeutics.
