Abstract:
Objective To explore the mechanism of Marsdenia tenacissima in the treatment of breast cancer through network pharmacology and experimental verification.Methods Literature retrieval was conducted to obtain the active components of Marsdenia tenacissima.The SwissTargetPrediction database was used to predict the potential targets of these active components.Targets of breast cancer were obtained from GeneCards,GEPIA2,OMIM,PharmGKB and TTD databases.The intersection targets were obtained,and a Marsdenia tenacissima-breast cancer-targets network was constructed using Cytoscape 3.9.0 software.The core targets were identified through protein-protein interaction(PPI)network analysis,followed by GO and KEGG pathway enrichment analysis to screen relevant signaling pathways.Molecular docking validation was performed for the top 10 key targets and major active components.The human breast cancer cell line MDA-MB-231 was treated with Marsdenia tenacissima injection in vitro.Cell proliferation ability was detected by CCK-8 assay and colony formation assay.Cell apoptosis was detected by Calcein-AM/PI staining and flow cytometry.Cell migration ability was detected by Transwell assay.Western blot experiment was used to validate the PI3K-AKT signaling pathway.Results Totally 37 active components and 276 potential targets against breast cancer were screened from Marsdenia tenacissima,including 11alpha-O-Benzoyl-12beta-O-acetyl tenacigenin B,Caffeic acid,Drevogenin A and Kaempferol.25 core targets were screened by PPI network such as AKT1,EGFR,TNF,CTNNB1 and IL-6,which mainly affected the estrogen signaling pathway,ErbB signaling pathway,HIF-1 signaling pathway and PI3K-AKT signaling pathway,etc.The molecular docking results showed that the main active components of Marsdenia tenacissima exhibited good binding activities with the core targets AKT1,ALB,CASP3,ESR1 and TNF.The results of in vitro experiments showed that Marsdenia tenacissima injection could inhibit the proliferation and migration ability of MDA-MB-231 cells(P<0.01,P<0.001)and induce apoptosis(P<0.001),as well as inhibit the activation of PI3K-AKT signaling pathway(P<0.05,P<0.01).Conclusion Marsdenia tenacissima may exert its anti-breast cancer effects through multiple targets and pathways,and the mechanism may be related to the inhibition of PI3K-AKT signaling pathway.
