Expression of MUC5AC and CD147 induced by CS extract in HBE cells. HBE cells were treated with various concentration of CS extract (from 5 to 15%) for 24 h. MUC5AC protein (a) and mRNA (b) levels were detected by ELISA and RT-PCR, respectively. CD147 protein (c) and mRNA (d) levels were assessed by Western blotting and RT-PCR, respectively. ^*p < 0.05, compared with 0% CS extract, ^**p < 0.05 vs. compared with 5% CS extract, ^***p < 0.05, compared with 10% CS extract. The data are representative of 3 separate experiments
