Effect of wogonin on the apoptosis of LPS-induced A549 cells. A A TUNEL assay was performed to determine apoptosis of LPS-treated A549 cells upon wogonin exposure. B The expression of apoptosis-related proteins in LPS-treated A549 cells upon wogonin exposure was measured by western blot analysis. Magnification, × 200. All experiments were performed in triplicates (n = 3). ***P < 0.001 vs. control; ^##P < 0.01, ^###P < 0.001 vs. LPS; ^&P < 0.05, ^&&P < 0.01, ^&&&P < 0.001 vs. LPS + 5 μM wogonin; ^@@P < 0.01 vs. LPS + 10 μM wogonin
