Gambogic acid induces apoptosis and inhibits colorectal tumor growth via mitochondrial pathways

Figure 6 Effects of gambogic acid on the expression of apoptosis-related factors in HT-29 cells. HT-29 cells were treated with gambogic acid (GA) for 48 h and Western blot was performed to measure levels of Fas receptor (A); Fas ligand (FasL) (B); FADD (C); apaf-1 (D); cytochrome c (E); pro-caspase-8 (F); pro-caspase-9 (G); and pro-caspase-3 (H). Data are reported as the mean ± SE of at least three experiments. ^aP < 0.05 vs 0 μmol/L.
