Effect of acacetin on the phosphorylation levels of PI3K and Akt in TGF-β1 (10 ng/ml)-treated GC cells. A Western blot analysis of the phosphorylation of PI3K and Akt in GC cells treated with acacetin. B GC cells were treated with TGF-β1 (10 ng/ml) in the absence or presence of acacetin. The quantitative values are expressed as the mean ± SD of three independent experiments. * p < 0.05, ** p < 0.01, *** p < 0.001 compared to the control group. # p < 0.05, ## p < 0.01 compared to the TGF-β1 alone group
