Abstract:Selenium‐containing compounds have demonstrated chemopreventive activity in a variety of chemically‐induced tumor models, but a unifying mechanism for this effect remains elusive. Altered disposition of chemicals and toxic metabolites may be contributing factors. Following dietary ingestion of selenocysteine pro‐drugs and selenocystine (15 ppm Se) for 1 month, mouse hepatic glutathione transferase, quinone oxidoreductase and microsomal epoxide hydrolase activities were elevated by 2‐butyl‐ and 2‐oxoselenazolid… Show more
