基于网络药理学和生物信息学分析的半枝莲黄酮类成分治疗胃癌的机制研究
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 UALCAN, HPA, 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=1.68-2.35, P<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, MYC, and 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.
