Abstract:

. There is limited information of the anti-inflammatory effects of Rg3 on inflamed lung cells and tissues. Therefore, we confirmed the anti-inflammatory mechanism of ginsenoside Rg3 in inflamed human airway epithelial cells (A549) and tissues whether Rg3 regulates nuclear factor kappa B (NF-B) activity.. To induce the inflammation, IL-1(10 ng/ml) was treated to A549 cells for 4 h. The effects of Rg3 on NF-B activity and COX-2 expression were evaluated by western blotting analysis in both IL-1-induced inflamed A549 cell and human asthmatic airway epithelial tissues. Using multiplex cytokines assay, the secretion levels of NF-B-mediated cytokines/chemokines were measured.. Rg3 showed the significant inhibition of NF-B activity thereby reduced COX-2 expression was determined in both IL-1-induced inflamed A549 cell and human asthmatic airway epithelial tissues. In addition, among NF-B-mediated cytokines, the secretion levels of IL-4, TNF-, and eotaxin were significantly decreased by Rg3 in asthma tissues. Even though there was no significant difference, IL-6, IL-9, and IL-13 secretion showed a lower tendency compared to saline-treated human asthmatic airway epithelial tissues.. The results from this study demonstrate the potential of Rg3 as an anti-inflammatory agent through regulating NF-B activity and reducing the secretion of NF-B-mediated cytokines/chemokines.
