2425856 Gutkina NI, Mishin VM, Liakhovich VV: [Induction of the phenobarbital form of cytochrome P-450 by chemically unrelated compounds]. Biokhimiia. 1986 Jul;51(7):1223-9.
The induction of the phenobarbital form of cytochrome P-450 by xenobiotics (phenobarbital, PB, hexachlorobenzene, HCB; hexachlorocyclohexane. HCCH, and aroclor 1016, Ar) was studied. It was demonstrated that administration of these compounds to animals is accompanied by an increase in the total cytochrome P-450, NADPH-cytochrome P-450 reductase, benzphetamine-N-demethylase and aldrin-epoxidase activities. Using monospecific antibodies against the cytochrome P-450 form isolated from PB-induced microsomes (PB-cytochrome P-450), a double immunodiffusion test revealed immunological identity of cytochrome P-450 forms induced by phenobarbital and other xenobiotics. The content of this form determined by rocket immunoelectrophoresis increased markedly and made up to 20-40% of the total cytochrome P-450 content. Antibodies against PB-cytochrome P-450 inhibited by 50-70% the benzphetamine-N-demethylase and aldrin-epoxidase activities, whereas the antibodies to methylcholanthrene-induced cytochrome P-450 were fairly ineffective. It was concluded that the chemically unrelated compounds induce in liver microsomes a cytochrome P-450 form, whose immunological properties and substrate specificity are close to the PB-form of cytochrome P-450.
