Differential effects of DIM and RES on binding of AhR to COX-2 XRE-1. The DNA protein-binding assay was performed with nuclear extracts harvested from MCF-7 cells cultured for 1.5 h with or without TCDD (100 nmol/L) plus DIM (A) or RES (B). Bars are means ± SE of triplicate measurements from 2 independent experiments. Means without a common letter differ, P < 0.05. (C) Control binding of the AhR to CYP1A1 XRE or COX-2 XRE-1 after treatment of MCF-7 cells with TCDD, 3M4NF (100 nmol/L), or their combination for 1.5 h.
