(a) The relative amount of ROS assessed on BEAS-2B cells after exposed to either carcinogen alone or with pretreatment of AF4. (b) Effects of AF4 on intracellular antioxidant enzymes (SOD1, catalase, and GPX1) along with carcinogen-treated groups as shown by western blotting. Beta-actin is used as in internal control to demonstrate equal protein in all tested samples. (c) TAC of BEAS-2B cells after various treatments was measured by a colorimetric kit-based method and showed in Trolox equivalence. Experimental values presented as mean ± SD of independent experiments. indicated statistical difference at .
