Mean expression levels of immunochemically detected CYP1A2/1 and CYP2B6 were almost 3-fold higher in Finnish microsomes, whereas CYP2E1 was 1.7-fold higher in Chinese samples. 4.

Of the eleven human CYP forms studied, CYP2E1 was the most active in forming benzyl alcohol, followed by CYP2B6, CYP2C8, CYP1A2, and CYP1A1, in that order.

Thus, h2E1 was responsible for the following percentages of the total metabolism in human liver: p-nitroanisole (35%), phenanthrene (23%), methylanisole to cresol (25%), methylanisole to methoxybenzyl alcohol (12%), toluene (40%), and chlorzoxazone (72%).

The genotypes of five metabolizing enzymes, that is, low Km aldehyde dehydrogenase (ALDH2), polymorphic N-acetyl transferase (NAT2), cytochrome P-4501A1 (CYP1A1), cytochrome P-4502E1 (CYP2E1), and glutathione-S-transferase mu (GSTM1) were determined form peripheral blood samples.

Western immunoblotting indicated that ethylbenzene treatment induced cytochrome P450 2B1/2B2 to a greater extent in male rats and cytochrome P450 2E1 only in females.
