摘要:目的:探讨黄芩苷对胃癌MGC-803和BGC-823细胞增殖和凋亡的影响及其可能的作用机制。方法:10、20、40、80、160和320μmol/L的黄芩苷分别作用MGC-803和BGC-823细胞24、48、72和96 h后,应用MTT法检测细胞的增殖情况。80、120和160μmol/L的黄芩苷处理MGC-803和BGC-823细胞48 h后,应用FCM法检测细胞的凋亡率,实时荧光定量PCR法和蛋白质印迹法分别检测细胞中自杀相关因子(factor associated suicide,FAS)、自杀相关因子配体(factor associated suicide ligand,FASL)、肿瘤坏死因子相关的凋亡诱导配体(tumor necrosis factor-related apoptosis-inducing ligand,TRAIL)、caspase 3和caspase 8 m RNA及蛋白的表达水平。结果:10~160μmol/L的黄芩苷可抑制MGC-803和BGC-823细胞的增殖,且呈现浓度和时间依赖性(P值均〈0.01)。80、120和160μmol/L的黄芩苷均可诱导MGC-803和BGC-823细胞的凋亡,且有浓度依赖性(P值均〈0.01)。80、120和160μmol/L的黄芩苷处理后,MGC-803和BGC-823细胞中FAS、FASL、TRAIL、caspase 3和caspase 8 m RNA及蛋白的表达水平均上调(P值均〈0.01)。结论:黄芩苷可抑制胃癌细胞的增殖并诱导其凋亡,这一作用可能与死亡受体通路有关。
Objective: To investigate the effects of baicalin on the proliferation and apoptosis of human gastric cancer BGC-823 and MGC-803 cells and to explore the possible molecular mechanism. Methods: The proliferation of MGC-803 and BGC-823 cells after treatment with 10, 20, 40, 80, 160 and 320 μmol/L baicalin for 24,48, 72 and 96 h, respectively was detected by MTT assay. After MGC-803 and BGC-823 cells treatment with 80, 120 and 160 mol/L baicalin for 48 h, the apoptosis was detected by FCM, and the expression levels of factor associated suicide (FAS), factor associated suicide ligand (FASL), tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), caspase 3 and caspase 8 mRNAs and proteins were measured by real-time fluorescent quantitative PCR and Western blotting, respectively. Results: 10-160 ~mol/L baicalin could suppress the proliferation of MGC-803 and BGC-823 cells in a concentration-and time-dependent manner (all P 〈 0.01). 80, 120 and 160 μmol/ L baicalin could induce the apoptosis of MGC-803 and BGC-823 cells in a concentration- dependent manner (all P 〈 0.01). The expression levels of FAS, FASL, TRAIL, caspase 3 and caspase 8 mRNAs and proteins in MGC-803 and BGC-823 cells after treatment with 80, 120 and 160 μmol/L baicalin were up-regulated (all P 〈 0.01). Conclusion: Baicalin can inhibit the proliferation This effect may be related to the death receptor of gastric cancer cells and induce apoptosis. pathway.
