Effect of LCDE on COX-2 and iNOS expression in with or without LPS-stimulated HaCaT cells. HaCaT cells were treated with LCDE (0, 0.1 and 0.25 μg/mL) with or without LPS (1 μg/mL) for at 37 °C 24 h. (A) The expression of COX2 and iNOS was quantified by western blot analysis. (B) Relative density of COX-2 expression. (C) Relative density of iNOS expression. Comparison with LCDE and LPS treated group **p < 0.01; ***p < 0.001. Comparison with LPS treated group ##p < 0.01; ###p < 0.001.
