Article Abstract

Aim: To investigate the effect of beta-ionone on the growth and apoptosis of gastric adenocarcinoma cell line SGC-7901.

Methods: Using MTT, fluorescence dye (Hoechst-33258), transmission electron microscopy and the TUNEL assay, we examined growth and apoptosis of SGC-7901 cells treated with beta-ionone at various concentrations (i.e. 25, 50, 100 and 200 micromol/L) for 24 h, 48 h.

Results: The growth of SGC-7901 cells was inhibited by beta-ionone. Seven days after treatment with beta-ionone at four concentrations, the inhibition rates were 12.04%, 30.59%, 78.25% and 94.15%, respectively. The IC(50) value of beta-ionone for SGC-7901 cells was estimated to be 89 micromol/L. The apoptotic morphology was demonstrated in SGC-7901 cells treated with beta-ionone by Hoechst-33258 staining and electron microscopy. Apoptosis was also shown in beta-ionone-treated SGC-7901 cells by the TUNEL assay.

Conclusion: beta-ionone can inhibit cell proliferation and induce apoptosis of SGC-7901 cells. However, the mechanism needs to be further investigated.
