Butadiene diolepoxide- and diepoxybutane-derived DNA adducts at N7-guanine: a high occurrence of diolepoxide-derived adducts in mouse lung after 1,3-butadiene exposure.

Abstract

Butadiene (BD) is a high production volume chemical and is known to be tumorigenic in rodents. BD is metabolized to butadiene monoepoxide (BMO), diepoxybutane (DEB) and butadiene diolepoxide (BDE). These epoxides are genotoxic and alkylate DNA both in vitro and in vivo, mainly at the N7 position of guanine. In this study, a 32P-post-labeling/thin-layer… (More)
