Fig. 3From: CC16 levels correlate with cigarette smoke exposure in bronchial epithelial cells and with lung function decline in smokersEffects of cigarette smoke extract (CSE) exposure on the expression levels of CC16 mRNA. Eight immortalized normal human bronchial epithelial cell lines were treated with CSE for 96 h after overnight serum starvation. CSE was then removed and washed with PBS for further culture for another 96 h in the absence of CSE. Data were shown as mean +/− standard deviation of eight cell lines and were analyzed by one-way ANOVA followed by Tukey’s multiple comparison tests. The p values for comparison of group means at 0 h vs 96 h, and 96 h vs 192 h, are also listed. * p < 0.001 vs PBS vehicle controlBack to article page
