Anti-Inflammatory Effect of ETAS®50 by Inhibiting Nuclear Factor-κB p65 Nuclear Import in Ultraviolet-B-Irradiated Normal Human Dermal Fibroblasts

Figure 3

Effect of ETAS on UV-B irradiation-induced p65 subcellular localization change in NHDFs. The cells were treated with 1 mg/mL ETAS or dextrin for 1 h after UV-B irradiation (20 mJ/cm2). (a) p65 and nuclei were probed with Alexa Fluor 488 and propidium iodide, which were visualized using FL1 (green fluorescence) and FL2 (red fluorescence) detectors, respectively, at 20× magnification. Data shown are representative of similar results from three independent experiments. (b) The ratio of nuclear p65-positive cells to total cells in the fields was calculated. Means ± SEM (n = 6). p < 0.01 (by one-way ANOVA and Tukey’s test).
