CYP1A1 and CYP1B1 expression levels analyzed by RT-qPCR in MCF-7 cells after treatment with isoflavones. MCF-7 cells were treated for 24 h with the isoflavones, GN, DZ, BA, and FN, and CYP1A1 and CYP1B1 expression was analyzed by RT-qPCR. (A, B) Effect of the ER agonists, GN and DZ, on (A) CYP1A1 and (B) CYP1B1 expression. (C, D) Effect of the AhR agonists, BA and FN, on (C) CYP1A1 and (D) CYP1B1 expression.
