Polyphenols 67-77 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 104-110 20883830-0 2011 Inhibition of 17beta-estradiol activation by CYP1A1: genotype- and regioselective inhibition by St. John"s Wort and several natural polyphenols. Polyphenols 132-143 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 45-51 20883830-9 2011 The data suggest that risk of estrogen-mediated diseases might be not only influenced by CYP1A1 genotype-dependent activation but also its inhibition by natural polyphenols of our diet and drugs. Polyphenols 161-172 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 89-95 17560072-0 2007 Developing a high-throughput system for the screening of cytochrome P450 1A1--inhibitory polyphenols. Polyphenols 89-100 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 57-76 12670496-0 2003 In vitro assessment of inhibition by natural polyphenols of metabolic activation of procarcinogens by human CYP1A1. Polyphenols 45-56 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 108-114 15661813-1 2005 The objective of this study was to examine the ability of dietary polyphenols to inhibit cytochrome P450 (CYP) 1A1 expression and activity and benzo[a]pyrene (BaP) DNA binding, with the main emphasis on prevention of chemical-induced hepatic carcinogenesis. Polyphenols 66-77 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 89-114 15661813-5 2005 Second, we screened 25 polyphenols with highly varying chemical structures for maximum ability to inhibit CYP1A1 activity in the Hep G2 cells.

Polyphenols 113-124 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 0-19 16484233-10 2006 Most importantly, western blotting showed all three polyphenols dramatically reducing BaP-induced CYP1A1 protein expression. Polyphenols 52-63 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 98-104 12670496-3 2003 We compared the effects of 11 representative natural polyphenols, which normally occur in food, on different activities of CYP1A1, namely epoxidation of 7,8-dihydrodiol-benzo[a]pyrene, the terminal step in the activation leading to the ultimate carcinogenic diolepoxides, hydroxylation of benzo[a]pyrene, and EROD. Polyphenols 53-64 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 123-129 12670496-5 2003 The results demonstrate that the inhibitory effects of dietary polyphenols on CYP1A1 activity depend on both the structure of the inhibitor and the type of the reaction and substrate used in the assay.

Polyphenols 10-21 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 111-130 23411228-5 2013 Moreover, these polyphenols up-regulated xenobiotic metabolizing enzymes UGT1A10 and CYP1A1, enhancing carcinogen detoxification. Polyphenols 16-27 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 85-91 22867086-3 2012 Using recombinant human enzyme, we confirmed earlier reported inhibitory effects of the polyphenols on cytochrome P4501A1 (CYP1A1) activity, and inhibition of metabolic clearance of FICZ was documented in FICZ-treated immortalized human keratinocytes (HaCaT).
