Abstract

Administration of cobalt chloride and 3-amino-1,2,4-triazole leads to a suppression of phenobarbitone-mediated increase in total cytochrome P-450 as well as cytochrome P-450b contents of the liver. This suppression is due to a decrease in the content of the protein species which is the result of a decrease in its rate of synthesis as measured in vivo and in vitro. Cobalt chloride as well as 3-amino-1,2,4-triazole treatments lead to a decrease in the translatability of cytochrome P-450b RNA without affecting total protein synthesis. It is a possibility that a small pool of heme regulates the RNA levels for the cytochrome P-450 species.
