Evidence from 32P-postlabeling and the use of pentachlorophenol for a novel metabolic activation pathway of diethylstilbestrol and its dimethyl ether in mouse live: likely alpha-hydroxylation of ethyl group(s) followed by sulfate conjugation.


Diethylstilbestrol (DES), a synthetic stilbene estrogen, is a potent development toxin and carcinogen in humans and rodents. A number of 32P-postlabeling studies suggest that genotoxic effects of DES substantially contribute to these biological effects. The mechanisms involved in DES-mediated genotoxicity are not completely understood, however. As reported… (More)
