摘要

目的:基于网络药理学和生物信息学探讨半枝莲黄酮类成分的抗胃癌作用机制及其关键靶点与通路。方法:通过TCMSP、ETCM等数据库筛选半枝莲所含黄酮类成分,结合SEA、Swiss Target Prediction等预测成分靶点,OMIM、DisGeNET等获取胃癌疾病靶点,取交集获得黄酮类成分的胃癌特异性靶点。利用STRING构建蛋白互作网络(PPI),Metascape进行通路富集分析,Cytohubba筛选Hub基因。采用分子对接验证黄酮类成分与Hub靶点的结合能力,并通过UALCAN、HPA、K-M plotter数据库验证Hub基因的mRNA、蛋白表达及预后意义。结果:筛选出36种黄酮类成分,131个胃癌特异性靶点(P=2.3e-21)。PPI网络富集于癌症通路、凋亡及增殖调控,核心簇Cluster3涉及凋亡调控。Hub基因为AKT1、EGFR、MYC、TP53。分子对接显示Carthamidin等与靶点结合稳定(结合能均≤-7 kcal·mol-1)。胃癌组织中AKT1、EGFR、TP53的mRNA及蛋白表达显著升高(P<0.05),MYC的mRNA及蛋白表达上调。Hub基因高表达患者生存期缩短(HR=1.68~2.35,P<0.01)。结论:半枝莲黄酮类成分通过靶向AKT1、EGFR、MYC和TP53基因异常表达,调控PI3K/Akt等通路抑制胃癌细胞增殖并诱导凋亡,其作用与病理分期、侵袭及转移相关,为多靶点抗胃癌机制研究提供依据。

Abstract

 Objective: To explore the anti-gastric cancer mechanism and key targets and pathways of flavonoids from Scutellaria barbata based on network pharmacology and bioinformatics.Methods: TCMSP ETCM and other databases were used to screen the flavonoids contained in Scutellaria barbata. Use SEA Swiss Target Prediction and other databases to predice component targets. OMIM DisGeNET and other databases were used to obtain gastric cancer disease targets and the intersection was used to obtain gastric cancer-specific targets of flavonoids. STRING was used to construct a protein-protein interaction PPI network. Metascape was used for pathway enrichment analysis and Cytohubba was used to screen Hub genes. The binding ability of flavonoids to Hub target was verified by molecular docking and the mRNA protein expression and prognostic significance of Hub gene were verified by UALCANHPA and K-M plotter databases.Results: 36 flavonoids and 131 gastric cancer-specific targets were screened out P=2.3e-21. The PPI network was enriched in cancer pathways apoptosis and proliferation regulation and the core cluster Cluster3 was involved in apoptosis regulation. Hub genes were AKT1 EGFR MYC and TP53. Molecular docking showed that the binding of Carthamidin and other targets were stable binding energy ≤ -7 kcal·mol-1. The mRNA and protein expressions of AKT1 EGFR and TP53 in gastric cancer tissues were significantly increased P<0.05 ), and the mRNA and protein expressions of MYC was up-regulated. The survival time of patients with Hub gene high expression was shortened HR=1.68-2.35P<0.01.Conclusion: The flavonoids from Scutellaria barbata inhibit the proliferation and induce apoptosis of gastric cancer cells by targeting the abnormal expression of AKT1 EGFR MYCand TP53 genes and regulating PI3K/Akt and other pathways. Its effect is related to pathological stage invasion and metastasis which provides a basis for the research on multi-target anti-gastric cancer mechanism.
