1 Anti-CYP2E1 significantly inhibited the metabolism of toluene to benzyl alcohol (BA) by about 50%, in microsomes from 1000 to 4000 ppm toluene-exposed rats, at low substrate concentration (0.2 mM). Toluene cytochrome P450, family 2, subfamily e, polypeptide 1 Rattus norvegicus
2 Anti-CYP2E1 significantly inhibited the metabolism of toluene to benzyl alcohol (BA) by about 50%, in microsomes from 1000 to 4000 ppm toluene-exposed rats, at low substrate concentration (0.2 mM). Toluene cytochrome P450, family 2, subfamily e, polypeptide 1 Rattus norvegicus
3 Immunoblot analysis with anti-CYP2E1 and anti-CYP2B1/2 revealed stronger immunoreactive bands in microsomes from rats exposed to more than 1000 and 2000 ppm of toluene, respectively. Toluene cytochrome P450, family 2, subfamily e, polypeptide 1 Rattus norvegicus
4 These results suggest that toluene induces CYP2E1, CYP2B1/2 and CYP3A1/2, but reduces CYP2C11/6, and has no effect on CYP1A1/2. Toluene cytochrome P450, family 2, subfamily e, polypeptide 1 Rattus norvegicus
