Active Lauraceae plant extracts activated the nuclear translocation of nuclear factor-erythroid 2-related factor 2 in MDA-MB-231 cells. The concentrations of extracts were 60 μg/mL for ZK-02 and ZK-05, and 90 μg/mL for ZK-04, ZK-08, and ZK-10. The cells were treated with each active extract or sulforaphane (2.5 μM) for 8 hours, and then subjected to indirect fluorescence staining. Data shown are representative of two independent experiments. (Color figure available online only.)
