Fig. 3. The effect of BSE on the cytokine expression of RAW 264.7 cells.RAW 264.7 cells were treated with LPS (1 μg/mL) and the indicated concentrations of BSE for 24 h. The expression of (A) TNF-α, (B) IL-6 and (C) IL-1β were analyzed by Western blot analysis. β-actin was used as the control. The statistical analysis of the data was carried out by use of a t-test. **p < 0.01 and ***p < 0.001 compared to control (each experiment, n = 3).
