Inhibitory effect of CJFE on the AhR signaling pathway induced by urban air pollutants. The inhibitory effect of CJFE on the AhR signaling pathway was determined by measuring the XRE-luciferase activity (a). The level of CYP1A1 expression in NHDFs was evaluated by quantitative RT-PCR assay (b). The results are mean ± standard deviation (SD) (n = 3). *P < 0.05, **P < 0.01 vs. pollutant-untreated control. #P < 0.05, ##P < 0.01 vs. pollutant-treated control
