1 TCDD-induced antagonism of MEHP-mediated migration and invasion partly involves aryl hydrocarbon receptor in MCF7 breast cancer cells. Polychlorinated Dibenzodioxins aryl hydrocarbon receptor Homo sapiens
2 Our data suggest that MEHP or TCDD can induce migration and invasion in MCF7 cells, and the promotion is partly AhR dependent. Polychlorinated Dibenzodioxins aryl hydrocarbon receptor Homo sapiens
3 We also observed that MEHP antagonized TCDD to reduce AhR-mediated CYP1A1 expression. Polychlorinated Dibenzodioxins aryl hydrocarbon receptor Homo sapiens
4 Subsequently, we revealed that MEHP recruited AhR to dioxin response element (DRE) sequences and decreased TCDD-induced AhR-DRE binding in CYP1A1 genes. Polychlorinated Dibenzodioxins aryl hydrocarbon receptor Homo sapiens
5 Overall, MEHP is a potential AHR agonist, capable of decreasing TCDD-induced AhR-DRE binding in CYP1A1 genes. Polychlorinated Dibenzodioxins aryl hydrocarbon receptor Homo sapiens
