Testosterone 0-12 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 188-196 9630843-0 1998 Involvement of CYP3A1, 2B1, and 2E1 in C-8 hydroxylation and CYP 1A2 and flavin-containing monooxygenase in N-demethylation of caffeine; identified by using inducer treated rat liver microsomes that are characterized with testosterone metabolic patterns. Testosterone 222-234 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 15-26 17498391-1 2007 PURPOSE: The purpose of this study was to quantify the intestinal metabolism of midazolam, a CYP P450 substrate, usually used as a probe for the activity of the isoform CYP3A4/1 and to compare it with previous results obtained for other P450 substrates such as testosterone, dextromethorphan and bupropion, which show some specificities for different CYP isoforms. Testosterone 261-273 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 169-177 17498391-1 2007 PURPOSE: The purpose of this study was to quantify the intestinal metabolism of midazolam, a CYP P450 substrate, usually used as a probe for the activity of the isoform CYP3A4/1 and to compare it with previous results obtained for other P450 substrates such as testosterone, dextromethorphan and bupropion, which show some specificities for different CYP isoforms.

Testosterone 65-77 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 51-54 9630843-4 1998 Liver microsomes isolated from rats pretreated with phenobarbital (PB-microsomes) did not have increased FMO activity but had increased activities for hydroxylating the testosterone at 6 beta-(CYP3A1), 16 beta-(CYP2B1), and 2 beta-(CYP3A1) positions. Testosterone 169-181 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 193-199 9630843-4 1998 Liver microsomes isolated from rats pretreated with phenobarbital (PB-microsomes) did not have increased FMO activity but had increased activities for hydroxylating the testosterone at 6 beta-(CYP3A1), 16 beta-(CYP2B1), and 2 beta-(CYP3A1) positions. Testosterone 169-181 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 232-238 9029268-8 1996 Since hydroxylation of testosterone at the 6 beta position in rats and humans is catalyzed primarily by CYP isoforms from the 3A subfamily, the increase in 6 beta-OHT suggests that Z induced CYP 3A activity. Testosterone 23-35 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 104-107 9520339-14 1998 There was a modest (2- to 3-fold) increase in CYP3A1/2 activity and immunoreactive protein, as determined by 6 beta-hydroxylation of testosterone and Western blot analysis. Testosterone 133-145 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 46-52 9394033-4 1997 Preincubation of microsomes from dexamethasone-treated rats with SD894 and NADPH resulted in a time-dependent inhibition of testosterone 6beta-hydroxylation (CYP 3A1/2 activity), which was decreased to 25% of controls after 30 min. Testosterone 124-136 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 158-167 9372837-8 1995 Similarly, the rate and pattern of CYP enzyme-mediated hydroxylation toward testosterone, 17 beta-estradiol, corticosterone, and lauric acid were greatly altered by nongenotoxic carcinogen treatment. Testosterone 76-88 cytochrome P450, family 3, subfamily a, polypeptide 23-polypeptide 1 Rattus norvegicus 35-38 8034584-9 1994 Similar effects were noted when the CYP3A1-dependent 6 beta-hydroxylation of testosterone was monitored.
