        摘   要   目的:研究五味子甲素对人鼻咽癌细胞HONE-1增殖、迁移和侵袭的影响及其可能机制。方法:以HONE-1细胞为研究
        模型,使用不同浓度[0(空白对照)、10、20、40 μmol/L]的五味子甲素处理后,分别采用CCK-8试验、划痕试验和Transwell小室试验
        检测细胞的增殖、迁移和侵袭能力变化;通过计算机分子对接分析五味子甲素与酪氨酸蛋白激酶(Met)蛋白的结合能力;采用
        Western blotting法检测细胞中磷酸化酪氨酸蛋白激酶(p-Met)、磷酸化磷脂酰肌醇-3-激酶(p-PI3K)、磷酸化蛋白激酶B(p-Akt)、B
        淋巴细胞瘤2(Bcl-2)和N-钙黏蛋白(N-cadherin)的相对表达量。结果:与空白对照比较,10、20、40 μmol/L五味子甲素处理后细胞
        的增殖、迁移和侵袭能力均显著减弱(P<0.05);分子对接结果显示,五味子甲素能与Met蛋白的活性口袋稳定结合;Western blot-
        ting试验结果显示,与空白对照比较,10、20、40 μmol/L五味子甲素处理后细胞中p-Met、p-PI3K、p-Akt、Bcl-2和N-cadherin蛋白的
        相对表达量均显著降低(P<0.05)。结论:五味子甲素可通过抑制Met/PI3K/Akt信号通路的活化来抑制HONE-1细胞的增殖、迁
        移和侵袭。

        ABSTRACT    OBJECTIVE:To study the effects and potential mechanism of deoxyschizandrin on the proliferation,migration and
        invasion of nasopharyngeal carcinoma cell HONE-1. METHODS:HONE-1 cell was set as cell model,while CCK-8 test,wound
        healing assay and Transwell chamber test were used to detect the proliferation,migration and invasion ability changes of HONE-1
        cells after treatment with different concentrations [0(blank control),10,20,40 μmol/L] of deoxyschizandrin. Computer molecular
        docking was performed to analyze the binding ability between deoxyschizandrin and Met protein. Western blotting assay was used
        to detect the relative protein expressions of p-Met,p-PI3K,p-Akt,Bcl-2 and N-cadherin in cells. RESULTS:Compared with
        blank control,the proliferation,migration and invasion ability of cells after treated with 10,20,40 μmol/L deoxyschizandrin were
        all decreased significantly (P<0.05). Results of molecular docking revealed that deoxyschizandrin could stably bind with the
        activity pocket of Met protein. Results of Western blotting assay demonstrated that compared with blank control,10,20,40
        μmol/L deoxyschizandrin all decreased the relative protein expressions of p-Met,p-PI3K,p-Akt,Bcl-2 and N-cadherin in cells
        significantly(P<0.05). CONCLUSIONS:Deoxyschizandrin can inhibit the proliferation,migration and invasion of HONE-1 cell
                                                            via inhibiting the activation of Met/PI3K/Akt signaling
