Fig. 2From: Effects of cigarette smoke on barrier function and tight junction proteins in the bronchial epithelium: protective role of cathelicidin LL-37Effects of CSE on the gene expression levels of TJ and AJ proteins in Calu-3 cells. Real-time quantitative reverse-transcriptase PCR analyses of gene expression levels for TJ and AJ proteins in Calu-3 cells exposed or unexposed to 10% CSE for the indicated times. Data were normalized to β-actin expression and expressed as means ± SEM (n = 4–6 per group). All results are representative of at least two independent experiments. *p < 0.05, **p < 0.01, ***p < 0.001, by two-way ANOVABack to article page
