摘要: 目的 探讨扶正抑瘤汤对非小细胞肺癌细胞增殖、侵袭、迁移、凋亡、自噬以及PI3K/Akt/mTOR信号通路的影响。方法 采用不同浓度(12.5 mg/mL、25 mg/mL、50 mg/mL、100 mg/mL、200 mg/mL、400 mg/mL)扶正抑瘤汤体外培养非小细胞肺癌A549细胞, CCK-8法测定细胞增殖抑制率;Transwell小室侵袭实验检测细胞侵袭能力;划痕实验检测细胞迁移能力;流式细胞仪检测细胞凋亡率;Western blot检测细胞自噬相关蛋白以及PI3K/Akt/mTOR信号通路相关蛋白的表达水平;透射电镜下观察自噬溶酶体形成情况。结果 200 mg/mL和400 mg/mL扶正抑瘤汤作用后A549细胞增殖抑制率增加(均P<0.05)。200 mg/mL扶正抑瘤汤作用后A549细胞侵袭和迁移能力降低(均P<0.05);细胞凋亡率增加(P<0.05);Beclin-1、LC3Ⅱ/Ⅰ蛋白的表达水平升高(均P<0.05),P62蛋白的表达水平降低(P<0.05);A549细胞自噬溶酶体数量增加;p-PI3K/PI3K、p-Akt/Akt和p-mTOR/mTOR蛋白的表达降低(均P<0.05)。结论 扶正抑瘤汤可以抑制A549细胞增殖,并促进细胞凋亡和自噬,可能与PI3K/Akt/mTOR信号通路失活有关,是治疗非小细胞肺癌的潜在药物。

Abstract: Objective To investigate the effects of Fuzheng Yiliu decoction on the proliferation, invasion, migration, apoptosis, autophagy and PI3K/Akt/mTOR signaling pathway of non-small cell lung cancer. Methods The non-small cell lung cancer A549 cells were cultured in vitro with different concentrations (12.5 mg/mL, 25 mg/mL, 50 mg/mL, 100 mg/mL, 200 mg/mL, 400 mg/mL) of Fuzheng Yiliu decoction, and the proliferation inhibition rate was determined by the CCK-8 assay; the invasion of cells was detected by Transwell assay; the cell migration was measured by the scratch test; the apoptosis rate was detected by the flow cytometry; the expression levels of autophagy-related proteins and PI3K/Akt/mTOR signaling pathway-related proteins were detected by the Western blot, and the formation of autophagy lysosome was observed under the transmission electron microscope. Results After treated with 200 mg/mL and 400 mg/mL of Fuzheng Yiliu decoction, the proliferation inhibition rate of A549 cells was increased (all P<0.05). After treated with 200 mg/mL of Fuzheng Yiliu decoction, the invasion and migration of A549 cells were decreased (all P<0.05); the apoptosis rate of A549 cells was increased (P<0.05); the expression levels of Beclin-1 and LC3Ⅱ/Ⅰ proteins were increased (all P<0.05), while the expression levels of P62 protein was decreased (P<0.05); the number of autophagy lysosomes increased in A549 cells; the expression levels of p-PI3K /PI3K, p-Akt /Akt, and p-MTOR /mTOR proteins were decreased (all P<0.05). Conclusions Fuzheng Yiliu decoction can inhibit the proliferation of A549 cells and promote cell apoptosis and autophagy, which may be related to the inactivation of PI3K/Akt/mTOR signaling pathway, and may be a potential drug for the treatment of non-small cell lung cancer.
