Gambogic acid (GA)-induced apoptosis of pancreatic cancer cells. Pancreatic cancer cells were treated with 0.0, 0.5, 1.0, and 2.0 μM GA for 24 h, respectively, and apoptosis was detected using flow cytometry. a PANC-1 cells; (b) BxPC-3 cells; (c) MIA PaCa-2 cells; (d) SW1990 cells. Data are presented as mean ± SD (n = 3); ** indicates P<0.01; *** indicates P<0.001
