Aromatase activity in KGN cells exposed to ICI (0.1 μM), NAR (3 μM), COU (10 μM) and QUE (10 μM). Striped bars present a co-exposure of ICI (0.1 μM) with tested phytoestrogens. Data are expressed as % of aromatase activity compared with 100% of aromatase activity in vehicle-control treated cells. The experiments were performed in duplicates and repeated three or four times (N = 3; N = 4). * or ^# significantly different from relevant solvent vehicle control Ethanol (0.1%) and/or DMSO (0.1%)-treated cells, respectively. ^## significantly different from COU (10 μM) or QUE (10 μM)-exposed cells. P < 0.05.
