Effects of Ferulic Acid on Gastric Cancer Cell Line MGC-803 Proliferation / 中国中医药信息杂志

ABSTRACT

Objective To explore the effects of ferulic acid on gastric cancer cell line MGC-803 proliferation;To discuss the mechanism of apoptosis induced by ferulic acid. Methods Ferulic acid with a variety of concentrations was used to treat gastric cancer cell line MGC-803 for 24, 48, 72 h;MTT experiment was used to detect the growth of gastric cancer cells. After gastric cancer cell line MGC-803 were treated with ferulic acid with a variety of concentrations (0, 5, 7.5, 10 mg/mL) for 48 h, all gastric cancer cells were collected and stained by Annexin V-FITC/PI for the detection of apoptosis by flow cytometry. RT-qPCR and Western-blot methods were used to detect mRNA and protein levels of Caspase-3, Caspase-9, Bax, Bcl-2 and Xiap. Results Compared with the control group, the OD value of cell line MGC-803 treated by ferulic acid with a variety of concentrations (5, 7.5, 10, 12.5 mg/mL) decreased significantly;the anti-tumor effect of ferulic acid was obvious;IC50 of 24, 48, and 72 hours after treated by ferulic acid was 12.93, 9.73 and 5.52 mg/mL respectively. Cell lineMGC-803 treated by ferulic acid with a variety of concentrations (5, 7.5, 10 mg/mL) after 48 h could induce the apoptosis of MGC-803 cells, up-regulate mRNA and protein levels of Caspase-3, Caspase-9, and Bax, down-regulate mRNA and protein levels of Bcl-2 and Xiap. Conclusion Ferulic acid can inhibit the proliferation of MGC-803 cells effectively and induce the apoptosis of MGC-803 cells, which mechanism is related to mitochondria apoptosis pathway and the down-regulation of Xiap expression.
