摘要:

目的 探讨生脉散改善非小细胞肺癌奥希替尼耐药的作用和机制。 方法 制备大鼠含药血清,单用或联合奥希替尼处理人肺癌细胞A549检测细胞活力的变化,试剂盒检测细胞葡萄糖和乳酸含量变化,构建小鼠皮下肺癌模型,观察生脉散联合奥希替尼使用对奥希替尼体内抗肺癌活性的影响。Western blotting、RT-qPCR和免疫荧光实验检测生脉散和乳酸对Wnt/β-catenin/LDHA信号通路的影响。 结果 生脉散以浓度依赖性增加A549细胞对奥希替尼的药物敏感性,与单用奥希替尼组比较,生脉散联合奥希替尼抑制细胞活力(P<0.001),克隆形成(P<0.001)和肺癌细胞体内增长(P<0.05),生脉散呈剂量依赖性减少A549细胞葡萄糖和乳酸含量(P<0.05)。Western blotting结果显示生脉散抑制LDHA、β-catenin总蛋白、细胞质和细胞核β-catenin蛋白表达(P<0.01),而乳酸则激活β-catenin总蛋白、细胞核β-catenin和LDHA蛋白表达(P<0.001);免疫荧光结果显示乳酸激活β-catenin蛋白核积累,而生脉散抑制细胞核β-catenin蛋白表达;RT-qPCR结果显示乳酸激活Wnt/β-catenin下游靶基因(c-myc、CD44、Axin2、Oct3/4、Survivin和CCND1)的表达(P<0.05),而生脉散则抑制其表达(P<0.05)。 结论 生脉散抑制肺癌细胞乳酸/Wnt/β-catenin/LDHA通路,抑制糖酵解水平,改善非小细胞肺癌奥希替尼耐药。

Abstract:

Objective To explore the effect of Shengmai San (SMS) for improving osimertinib resistance in non-small cell lung cancer cells and the underlying mechanism. Methods Cultured A549 cells were treated with osimertinib alone or in combination with SMS-medicated rat serum, and the changes in cell viability and glucose and lactate levels were determined. The effect of SMS combined with osimertinib for improving osimertinib resistance of A549 cells was assessed in a mouse model bearing subcutaneous A549 cell xenograft. Western blotting, RT-qPCR, and immunofluorescence staining were used to analyze the effects of SMS and lactate on the Wnt/β‑catenin/LDHA signaling pathway. Results SMS significantly increased osimertinib sensitivity of A549 cells in a concentration-dependent manner. Compared with osimertinib alone, the combined treatment with SMS and osimertinib significantly inhibited cell viability, colony formation ability, and tumor growth in nude mice. SMS concentration-dependently decreased glucose and lactate levels in A549 cells. The results of Western blotting showed that SM inhibited the protein expression of LDHA, total β‑catenin, and cytoplasmic and nuclear β‑catenin, while lactate obviously activated the expressions of total β‑catenin protein, nuclear β‑catenin, and LDHA in A549 cells. Immunofluorescence concentration-dependent staining showed that lactic acid activated nuclear accumulation of β‑catenin protein, while SMS significantly inhibited the expression of nuclear β‑catenin protein; RT-qPCR demonstrated that lactate significantly increased mRNA expressions of the Wnt/β‑catenin downstream target genes (c-myc, CD44, Axin2, Oct3/4, survivin, and CCND1), while SMS inhibited their expressions. Conclusion SMS improves osimertinib resistance in non-small cell lung cancer cells by inhibiting lactate/Wnt/β-catenin/LDHA pathway-mediated glycolysis.
