Figure 6. Effect of cis-UCA on UV-irradiation-induced IL-8 secretion. The HCE-2 cells (A) and HCECs (B) were non-irradiated (C), UV-irradiated (UV), treated with 100 mg/ml cis-UCA (c-UCA), or UV-irradiated and treated with cis-UCA (100 mg/ml c-UCA+UV) for 24, 48, or 72 h. Statistical significance is shown by an asterisk (p<0.05) or a double asterisk (p<0.001; n=6 dishes). Compared samples are shown by the horizontal lines.
