To determine which of the N-acetyltransferase (NAT) alleles [monomorphic (NAT1) or polymorphic (NAT2)] are expressed in the target cells for arylamine carcinogenesis, namely normal human uroepithelial cells, cDNA was prepared from cellular RNA and amplified by polymerase chain reaction (PCR), using upstream primer 1 comprising the 5' end (nt 47-68) and either downstream primers 2 (nt 908-889) or 3 (nt 953-931) corresponding with the 3' end.

We conclude that the acetylator status is not a major factor in lung cancer risk, however the presence of the 341C + 481T + 803G and the 590A alleles of the polymorphic NAT2 gene may be a secondary risk factor for the development of lung cancer.
