Regulation of MAPKs Signaling Contributes to the Growth Inhibition of 1,7-Dihydroxy-3,4-dimethoxyxanthone on Multidrug Resistance A549/Taxol Cells

Figure 3

XAN induced apoptosis of A549/Taxol cells, and MAPKs inhibitors exerted divergent effects on the results. (a) Normal; (b) XAN (5.2 μM); (c) XAN (20.8 μM); (d) XAN (20.8 μM) + SB (25 μM); (e) XAN (20.8 μM) + SP (25 μM); (f) XAN (20.8 μM) + U0126 (10 μM).
