1 Involvement of a post-transcriptional mechanism in the inhibition of CYP1A1 expression by resveratrol in breast cancer cells. Resveratrol cytochrome P450 family 1 subfamily A member 1 Homo sapiens
2 Resveratrol decreases basal and induced CYP1A1 mRNA/protein levels in both in vitro and in vivo models, and some studies suggest that resveratrol acts as an aryl hydrocarbon receptor (AhR) antagonist. Resveratrol cytochrome P450 family 1 subfamily A member 1 Homo sapiens
3 Treatment of T47D or MCF-7 cells with 10 microM resveratrol inhibited induction of CYP1A1 mRNA and CYP1A1-dependent activity after treatment with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), as previously reported. Resveratrol cytochrome P450 family 1 subfamily A member 1 Homo sapiens
4 Treatment of T47D or MCF-7 cells with 10 microM resveratrol inhibited induction of CYP1A1 mRNA and CYP1A1-dependent activity after treatment with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), as previously reported. Resveratrol cytochrome P450 family 1 subfamily A member 1 Homo sapiens
5 Actinomycin D chase experiments in T47D cells showed that resveratrol and dehydroepiandrosterone both increased the rate of CYP1A1 mRNA degradation, whereas resveratrol did not affect CYP1A1-dependent activity in cells pretreated with TCDD for 18 hr. Resveratrol cytochrome P450 family 1 subfamily A member 1 Homo sapiens
6 These data suggest that resveratrol inhibits CYP1A1 via an AhR-independent post-transcriptional pathway. Resveratrol cytochrome P450 family 1 subfamily A member 1 Homo sapiens
