High-density oligonucleotide microarrays and functional network analysis reveal extended lung carcinogenesis pathway maps and multiple interacting genes in NNK [4-(methylnitrosamino)-1-(3-pyridyle)-1-butanone] induced CD1 mouse lung tumor

摘要

NNK [4-(methylnitrosamino)-1-(3-pyridyle)-1-butanone] is a nicotine-derived nitrosaminoketone contained in tobacco smoke used as a powerful chemical carcinogen for rodent experimental models of pulmonary carcinogenesis. To clarify its carcinogenetic mechanisms, we examined the expression status of 22,625 mouse genes.
