According to recent research from Tsukiji, Japan, "2-Amino-1-methyl-6-phenylimidazo[4,5-b] pyridine ( PhIP) is the most abundant heterocyclic amine in cooked foods, and is both mutagenic and carcinogenic. It has been suspected that the carcinogenicity of PhIP is derived from its ability to form DNA adducts, principally dG-C8-PhIP."
"To shed further light on the molecular mechanisms underlying the induction of mutations by PhIP, in vitro DNA synthesis analyses were carried out using a dG-C8-PhIP-modified oligonucleotide template. In this template, the dG-C8-PhIP adduct was introduced into the second G of the TCC GGG AAC sequence located in the 5' region. This ...
