摘要: 目的 采用网络药理学和体外研究探讨木犀草素(luteolin)抑制食管鳞状细胞癌(esophageal squamous cell carcinoma, ESCC)的分子机制。方法 通过构建活性成分和疾病维恩图(Venn图)确定木犀草素和ESCC共同靶点,String数据库将共同靶点进行可视化,建立蛋白互作网络(PPI)。使用Cytoscape 3.9.1内置插件对Hub基因筛选,并运用R语言进行基因本体(GO)生物过程富集分析及KEGG通路分析。体外试验观察木犀草素对ESCC细胞系(TE-13和KYSE-510)的抑制作用,采用分子对接验证木犀草素和部分Hub基因的结合活性。结果 共收集到木犀草素与ESCC共同靶点69个,并筛选出以AKT1ESR1SRC为代表的Hub靶基因。靶点主要涉及细胞氧化应激、蛋白质修饰等生物学功能和活性氧、炎症、细胞外基质等信号通路。其中选择PI3K-Akt信号通路验证网络药理分析结果的合理性。体外研究表明,木犀草素可阻止TE-13和KYSE-510细胞增殖、迁移和侵袭的能力,并抑制了FAK-SRC-PI3K-Akt通路中磷酸化蛋白的表达。此外,分子对接结果表明,木犀草素对FAK、SRC、Akt蛋白表现出良好的亲和力。结论 木犀草素对ESCC的抑制性表现出多靶点多通路的特征,其阻碍了ESCC细胞增殖、迁移和侵袭,这可能与抑制FAK-SRC-PI3K-Akt通路有关。

Abstract: Objective To investigate the molecular mechanism by which luteolin inhibits esophageal squamous cell carcinoma (ESCC) based on network pharmacology and in vitro studies. Methods The common targets of luteolin and ESCC were identified by constructing Venn diagrams of active ingredients and diseases. The common targets were visualized via the String database before a protein-protein interaction network (PPI) was established. The Hub genes were screened using the plug-in of Cytoscape 3.9.1. Gene Ontology (GO) enrichment analysis and KEGG pathway analysis were performed using the R programming language. The inhibitory effect of luteolin on ESCC cell lines (TE-13 and KYSE-510) was observed in vitro, and the binding activity of luteolin and Hub genes was verified by molecular docking. Results A total of 69 common targets of luteolin and ESCC were collected, and Hub target genes represented by AKT1, ESR1 and SRC were screened. The targets involved not only such biological functions as cellular oxidative stress and protein modification, but such signaling pathways as reactive oxygen species, inflammation, and extracellular matrix. The PI3K-Akt signaling was selected to verify the rationality of the results of the network pharmacology analysis. In vitro studies showed that luteolin inhibited the ability of TE-13 and KYSE-510 cells to proliferate, migrate, and invade, and reduced the expressions of phosphorylated proteins in the FAK-SRC-PI3K-Akt pathway. In addition, the results of molecular docking showed that luteolin showed good affinity for FAK, SRC and Akt. Conclusion The inhibition of ESCC by luteolin is characterized by multiple targets and multiple pathways, which may be related to the inhibition of the FAK-SRC-PI3K-Akt pathway.
