Human arylamine N-acetyltransferase 1 (NAT1) is a well-known phase II metabolic enzyme that has been associated with carcinogenesis. Its role in the biotransformation of aromatic and heterocyclic amine carcinogens has been investigated for many years, but more recent investigations focus on a possible endogenous role of human NAT1 in cancer initiation and progression. We conducted in vivo studies using homozygous Fischer 344 rats, congenic at the rat Nat2 locus for high (rapid) and low (slow) activity. Wistar Kyoto inbred rats were used to breed in the slow activity rat Nat2 locus into the Fischer 344 inbred rat, which contains the …
