Figure 2From: Diesel exhaust particles induce CYP1A1 and pro-inflammatory responses via differential pathways in human bronchial epithelial cellsDEP-induced mRNA expression of multiple inflammation-related genes. Human bronchial epithelial BEAS-2B cells were exposed to 100 μg/ml DEPs for 4 h. Relative quantification of mRNA levels was performed by QRT-PCR. Bars represent means ± SEM of the relative change compared to control cells after normalization for beta-actin mRNA levels, detected in three independent experiments. * more than two-fold increase compared to control (dotted line) in all three experiments.Back to article page
