Flavonoid screen for AHR-dependent activity. HepG2 (40/6) cells harboring the AHR-responsive pGudluc 6.1reporter vector were treated with vehicle (DMSO), 10 nM TCDD as a positive control, or the indicated compounds (10 μM) for 6 h; cells were lysed, and luciferase activity was determined. Data represent mean luciferase units ± S.E.M. and were normalized for protein concentration.
