摘要：目的观察阿魏酸对人胃癌MGC-803细胞增殖的影响,探讨其诱导胃癌细胞凋亡的作用机制。方法不同浓度阿魏酸干预体外培养人胃癌MGC-803细胞,作用24、48、72 h后,MTT法检测细胞增殖;不同浓度(0、5、7.5、10 mg/m L)阿魏酸作用MGC-803细胞48 h,Annexin V-FITC/PI法和流式细胞仪检测细胞凋亡,RT-q PCR和Western-blot检测Capase-3、Capase-9、Bax、Bcl-2和Xiap的m RNA和蛋白表达。结果与对照组比较,5、7.5、10、12.5 mg/m L阿魏酸作用MGC-803细胞的OD值明显降低,阿魏酸抑瘤作用明显,阿魏酸作用MGC-803细胞24、48、72 h的IC50分别为12.93、9.73、5.52 mg/m L;5、7.5、10 mg/m L阿魏酸作用MGC-803细胞48 h后均能诱导MGC-803细胞凋亡,5、7.5、10 mg/m L阿魏酸均能上调Capase-3、Capase-9和Bax的m RNA和蛋白表达,下调Bcl-2和Xiap的m RNA和蛋白表达。结论阿魏酸能有效抑制MGC-803细胞增殖,并能诱导MGC-803细胞凋亡,其作用机制与内源性线粒体凋亡途径和下调Xiap的表达有关。
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/m L） 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-q PCR and Western-blot methods were used to detect m RNA 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/m L） 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/m L respectively. Cell line MGC-803 treated by ferulic acid with a variety of concentrations（5, 7.5, 10 mg/m L） after 48 h could induce the apoptosis of MGC-803 cells, up-regulate m RNA and protein levels of Caspase-3, Caspase-9, and Bax, down-regulate m RNA 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.
