CS induces IL-8 expression and release in pulmonary epithelial cells in vitro. (A) NCI-H292 cells were treated with CSE for 6 h. A panel of 16 chemokines and cytokines were measured by real-time PCR (n = 9 per group). (B) The cells were treated with different concentrations of CSE for 24 h. Then the cells were exposed to 2.5% CSE for different times (2–24 h). The mRNA and protein of IL-8 were separately assessed by RT-PCR and ELISA (n = 9 per group). Data were expressed as mean ± SEM of three independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001, compared with control.
