Abstract

Exposure to acrylonitrile induces formation of tumors at multiple sites in rats, with females being more sensitive. The present study assessed possible mechanisms of acrylonitrile tumorigenicity, covalent DNA binding, DNA breakage, and oxidative DNA damage, in two target tissues, the brain and Zymbal's glands, of sensitive female Fischer (F344) and Sprague-Dawley (SD) rats. One group received acrylonitrile in drinking water at 100 ppm for 28 days. Two other groups were administered either acrylonitrile in drinking water at 100 ppm or drinking water alone for 27 days, followed by a single oral gavage dose of 11 mg/kg bw
