Isoflavone extract inhibited TNF-α- and IL-17A-induced NF-κB phosphorylation in human primary keratinocytes. Primary keratinocytes were pretreated with different doses of isoflavone extract for 24 hours and then treated with TNF-α or IL-17A. After treatment with TNFα (A) or IL-17A (C), with the quantification data shown in the right panel (B,D), the total protein was extracted from the cells and IκBα expression was determined via western blotting. Data were the mean ± SEM from at least three independent experiments. *P < 0.05, indicating significant effects of isoflavone extract as compared to control.
