Arecoline 27-36 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 65-71 17707585-0 2007 Differential effect of arecoline on the endogenous dioxin-responsive cytochrome P450 1A1 and on a stably transfected dioxin-responsive element-driven reporter in human hepatoma cells. Arecoline 23-32 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 69-88 17707585-3 2007 It was also shown that arecoline, a major areca nut alkaloid, inhibited the 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced cytochrome P450 1A1 (CYP1A1) activation in Huh-7 cells. Arecoline 23-32 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 127-146 17707585-3 2007 It was also shown that arecoline, a major areca nut alkaloid, inhibited the 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced cytochrome P450 1A1 (CYP1A1) activation in Huh-7 cells. Arecoline 23-32 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 148-154 17707585-5 2007 In the present study, the effect of arecoline on the TCDD-induced activation of DRE-CALUX and CYP1A1 enzyme in Huh7-DRE-Luc and Huh-7 cells, respectively, was examined. Arecoline 36-45 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 94-100 17707585-6 2007 It was found that arecoline inhibited TCDD-induced CYP1A1 activation and however enhanced TCDD-induced DRE-CALUX activation. Arecoline 18-27 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 51-57 17707585-7 2007 This finding indicates the differential effect of arecoline on the endogenous dioxin-responsive CYP1A1 and on a stably transfected DRE-driven reporter in human hepatoma cells. Arecoline 50-59 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 96-102 17234337-0 2007 Arecoline inhibits the 2,3,7,8-tetrachlorodibenzo-p-dioxin-induced cytochrome P450 1A1 activation in human hepatoma cells. Arecoline 0-9 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 67-86 17234337-1 2007 In the present study, we investigated the effect of arecoline, a major areca nut alkaloid, on the 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced activation of cytochrome P4501A1 (CYP1A1) in a human hepatoma cell line Huh-7. Arecoline 52-61 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 183-189 17234337-4 2007 By using real-time RT-PCR, we demonstrated that arecoline inhibited the TCDD-induced activations of CYP1A1 and AhR repressor (AhRR) mRNA expression in a similar pattern. Arecoline 48-57 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 100-106 17234337-6 2007 Therefore, in our present study, the observed inhibitory effect of arecoline on CYP1A1 activation was not due to the up-regulation of AhRR or direct inhibitory effect on CYP1A1. Arecoline 67-76 cytochrome P450 family 1 subfamily A member 1 Homo sapiens 80-86 17234337-7 2007 Taken together, here we have demonstrated that arecoline attenuates the TCDD-induced CYP1A1 activation mainly via down-regulation of AhR expression in human hepatoma cells, suggesting the possible involvement of arecoline in the AhR-mediated metabolism of environmental toxicants in liver.
