Luciferase reporter gene assay of the plant extracts from the family Lauraceae. The stable MDA-MB-231 cells expressing antioxidant response element-luciferase were seeded in 96-well plates and treated with several doses of each plant extract (μg/mL) or sulforaphane (2.5 μM) for 16 hours before analysis of luciferase activity. Results are presented as the mean ± SD (n = 3). * P < 0.05 vs. “Con” group.
