摘要:
Objective To investigate the anti-glioma effect of schisandrin C, and its mechanism based on network pharmacology, molecular docking technology and in vitro experimental validation. Methods Schisandrin C related targets were screened through databases such as TCMSP, and glioma related targets were collected using databases like GeneCards. The intersection targets between schisandrin C and glioma were identified and a Venn diagram was drawn. PPI network was constructed using the STRING database, and core intersection targets were screened using the Cytoscape software. GO and KEGG enrichment analyses of the intersecting targets were performed using the DAVID database. The binding ability of schisandrin C to the core intersection targets was verified by molecular docking using AutoDock software, and visualised and analysed using PyMol software. Finally, human glioma U251 cells were treated with schisandrin C (25, 50, and 100 μmol/L), and CCK-8, scratch assay and Western Blotting were applied to detect the effects of different concentrations of schisandrin C on cell proliferation, migration and protein expression. Results A total of 98 drug targets, 3 230 disease targets, and 63 drug-disease intersection targets were screened, and the core targets were Akt1, EGFR, SRC, mTOR, ERBB2, PIK3CA, etc. 142 KEGG pathways were identified, which mainly included PI3K/Akt, Rap1, and HIF-1 signalling pathways. In vitro studies found that compared with the control group, schisandrin C 50 and 100 μmol/L inhibited the proliferation and migration of human glioma U251 cells, and low, schisandrin C 25, 50, and 100 μmol/L groupsignificantly reduced the expression of PI3K/Akt pathway-related proteins (P < 0.05, 0.01, 0.001), p-Akt and p-ERK1/2 proteins. Conclusion Schisandrin C may inhibit the proliferation and migration of human glioma U251 cells through the PI3K/Akt signalling pathway. © 2025 Tianjin Press of Chinese Herbal Medicines.
