Cytotoxicity of xanthohumol (Xn) on GC cells and normal gastric epithelial cells. (A) GC cells (MGC-803, SGC-7901 and AGS) and normal gastric epithelial cells (GES-1) were treated with Xn at concentrations of 0–100 µM for 24 h. (B) The IC₅₀ for each cancer cell line was calculated according to the data in (A). Cell viability was determined by the MTS assay. Treatment with 0 µM Xn was used as control. Data are expressed as mean ± standard error of the mean. n=3. *P<0.05, **P<0.01 vs. control (0 µM Xn).
