Inhibition of eotaxin-1 expression by astragalin in LPS- or H
-exposed BEAS-2B cells. After BEAS-2B cell culture protocols with 2 μg/ml LPS for 8 h (A) and or 20 μM H2O2 for 24 h (B), cell lysates were prepared for Western blotting with anti-eotaxin-1. β-Actin protein was used as an internal control. The bar graphs (mean ± SEM, n = 3-4) represent quantitative results of the upper bands obtained from a densitometer. Means not sharing a common superscript refer to significant different at P < 0.05.
