摘要:

目的:探究红杉黄酮影响胃癌细胞的分子机制。方法:通过梯度浓度红杉黄酮处理胃癌细胞系AGS细胞,再使用PI3K/AKT信号通路激活剂对细胞进行诱导。采用CCK-8检测红杉黄酮对AGS细胞的最佳抑制浓度及时间,使用平板克隆、Transwell、细胞划痕实验检测细胞的增殖、迁移、侵袭能力变化。Western blot检测PI3K/AKT信号通路关键蛋白p-PI3K、PI3K、p-AKT、AKT。结果:红杉黄酮呈浓度依赖抑制AGS细胞,其半抑制浓度为0.5 mmol/L,最佳处理时间为48 h。红杉黄酮处理AGS细胞后,p-PI3K与p-AKT表达下调,AGS细胞增殖减少,迁移、侵袭能力降低;PI3K/AKT信号通路激活剂处理后,p-PI3K与p-AKT表达被部分逆转,增殖、迁移、侵袭能力降低也得到部分改善。结论:红杉黄酮通过失活PI3K/AKT信号通路抑制胃癌细胞增殖、迁移、侵袭等恶性行为。

Abstract:

AIM: To explore the molecular mechanism of sequoiaflavone affecting gastric cancer cells. MEHTODS: Gastric cancer cell line AGS cells were treated with gradient concentrations of sequoiaflavone, and then induced by PI3K/AKT signaling pathway activator. The optimal inhibitory concentration and time of semi-inhibitory concentration of red cedar flavonoid on AGS cells were detected by CCK-8, and the changes of cell proliferation, migration and invasion ability were detected by colony formation assay, transwell assay and wound healing assay. PI3K/AKT signal pathway related proteins p-PI3K, PI3K, p-AKT and AKT  were detected by western blot. RESULTS: Sequoiaflavone inhibited AGS cells in a concentration-dependent manner. The half inhibitory concentration was 0.5 mmol/L, the optimal treatment time was 48 h. The protein expression of p-PI3K and p-AKT was down regulated. The proliferation, migration and invasion of AGS cells were decreased after treated with sequoiaflavone. After treated with PI3K/AKT signal pathway activator, the protein expression level of p-PI3K and p-AKT was partially reversed, and the ability of cell viability, proliferation, migration and invasion was also partially improved. CONCLUSION: Inactivation of PI3K/AKT signaling pathway caused by sequoiaflavone inhibited gastric cancer cells proliferation, migration and invasion ability. 

Key words: gastric cancer, sequoiaflavone, PI3K, AKT, proliferation, invasion, migration
