Time course of GCLM, HO1 and NQO1 steady-state RNA levels following treatment of RAW264.7 cells with electrophilic compounds. qPCR analysis showing relative mRNA levels following the treatment with 10 μM NCE-1, -2, -8, -10, OA-NO2, DMF and 100 nM CDDO-Im for 2, 4, 8 and 16 hr in RAW cells. The values in the bar graph represent mean ± SEM for at least three independent experiments (n = 3–12). Compared to the vehicle (DMSO) treatment group at each time point, statistical significance is indicated by: (a) p < 0.05; (b) p < 0.01 and (c) p < 0.001.
