SHORT COMMUNICATION: Formation of 8-hydroxydeoxyguanosine (8-OH-dG) in rat kidney DNA after intraperitoneal administration of ferric nitrilotriacetate (Fe—NTA)

Abstract
A significant increase of 8-hydroxydeoxyguanosine (8-OH-dG) was observed in the kidney DNA of rats given a renal carcinogen, the ferric complex of nitrilotriacetate (Fe—NTA) by single i.p. injection. By contrast, non- or weakly carcinogenic compounds, aluminum — nitrilotriacetate complex (A1—NTA), non-complexed NTA (Na2NTA) and ferric chloride had no effect on 8-OH-dG production in the kidney DNA. These results suggest the involvement of active oxygen radicals in Fe—NTA carcinogenesis.
