β-Asarone inhibits gastric cancer cell proliferation and increases chemosensitivity. (a) Single usage of β-asarone or cisplatin and combining usage mediated cell proliferation inhibition with gradient concentrations for 24 h. IC50 values of each drug were following measured. (b) Median-effect principle was used to determine the synergistic effect of combining usage. fa-CI curve graph of MGC803 (upper), SGC7901 (medium), and MKN74 (lower) showed a different section of fa when CI < 1.The results of three independent experiments are expressed as mean ± SD, ^∗P < 0.05; ^∗∗P < 0.01 (Student's t-test) indicate a significant difference vs. the control.
