Dose-dependent effect of Biodiesel and Diesel emission extracts on CYP1A1, IL-8, and COX-2 mRNA expression. Effect of organic extracts preparations of S100 and CARB Diesel on CYP1A1, IL-8, and COX-2 mRNA expression in U937 macrophages. U937 macrophages were treated for 24 h with 5, 10 and 50 μg/ml S100 or CARB ULSD. Increased mRNA levels of target genes are shown and corrected against the housekeeping gene β-actin. As a positive control, cells were treated with 10 μg/ml SRM 1650 or 1 nM TCDD. Values are given as mean ± SD of three independent experiments. An asterisk indicates significantly different from control cells (p < 0.05).
