产品描述 | 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a tobacco-specific nitrosamine carcinogen.1Reactive metabolites of NNK alkylate DNA, forming pyridyloxobutyl (POB) and pyridylhydroxybutyl (PHB) adducts, and induce DNA methylation. NNK (100 mg/kg, single dose) increases the protein levels of DNA methyltransferase 1 (DNMT1) in mouse bronchial epithelial cells within one day and increases hypermethylation of the tumor suppressor genesChd13,Prdm2, andRunx3in lung tissue within three days.2It induces tumor formation preferentially in the lungviavarious routes of administration in animal models.3NNK induces adenomas and adenocarcinomas, which are present after 16 and 50 weeks, respectively, in mouse lung when administered at a single dose of 10 µmol/animal. Lifetime administration of NNK (63.5 mg/animal) to rats results in a 90% incidence of lung tumors.4 1.Carlson, E.S., Upadhyaya, P., Villalta, P.W., et al.Analysis and identification of 2’-deoxyadenosine-derived adducts in lung and lover DNA of F-344 rats treated with the tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone and enantiomers of its metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanolChem.
