Fig. 2From: The pro-inflammatory effects of combined exposure to diesel exhaust particles and mineral particles in human bronchial epithelial cellsExpression of genes related to inflammation and redox responses after combined exposure to DEPB0 and α-quartz. HBEC3-KT cells were exposed to 25 μg/mL (2.6 μg/cm2) DEPB0 and 50–100 μg/mL (5.3–10.5 μg/cm2) α-quartz for 2 h (i), 6 h (ii) and 12 h (iii), alone or in combination. The expression of CXCL8 (A), IL-1β (B), IL-1α (C), COX-2 (D) and HO-1 (E) was determined using qPCR. Results are expressed as fold change compared to unexposed cells and presented as boxplots of 4 independent experiments (Box: 25th-75th percentile, whiskers: minimum and maximum values, line: median, +: mean). Statistically significant differences were determined using two-way repeated measures ANOVA followed by Dunnett’s and Å Ãdák's post-tests and were calculated from the normalized CT values. *Statistically significant difference from the respective control at 0 μg/mL α-quartz. #Statistically significant difference between exposure groupsBack to article page
