Abstract:

Objective  To explore the effect of C-X-C motif chemokine ligand-13 (CXCL-13) on the proliferation and migration of human bone marrow mesenchymal stem cells (BMSCs) by network pharmacology.    Methods  To predict that the targets of CXCL-13 on BMSCs by online database. Metascape was used to perform gene ontology (GO) of the targets and Kyoto encyclopedia of genes and genomes(KEGG)pathway was used to perform enrichment analysis. The protein interaction analysis was performed by STRING 11.0 database, and the protein module of core gene was screened by using the cytoHubba 0.1 of Cytoscape 3.8. We divided BMSCs into control group, CXCL-13 group and PI3K inhibitor group. MTT assay, flow cytometric analysis and Transwell cell migration assay were respectively used to detect the absorbance (A) value of BMSCs in each group, the apoptosis rate and the number of cell migration. The protein contents of epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF) in BMSCs supernatant were determined by ELISA. Western blotting was used to detect the protein expression of Akt and phosphorylated Akt (p-Akt) of BMSCs in each group.    Results  It was predicted that 21 targets of CXCL-13 effect on BMSCs. There were 32 biological processes related to cell proliferation include stem cell proliferation, regulation of endothelial cell proliferation and positive regulation of smooth muscle cell proliferation. There were 22 biological processes related to cell migration include regulating cell migration, amebic cell migration and endothelial cell migration. There were 40 KEGG pathways including cancer pathway, PI3K-Akt signaling pathway and MAPK signaling pathway. The core proteins included tumor protein P53 (TP53), epidermal growth factor receptor (EGFR), heat shock protein 90 kD alpha class B member 1 (HSP90AB1), protein kinase Cα (PRKCA), estrogen receptor 2 (ESR2) and prostaglandin E receptor 4 (PTGER4). Compared with other groups, the absorbance(A) value and cell migration number of BMSCs in CXCL-13 group increased significantly (P<0.01, n=15), and the apoptosis rate decreased significantly (P<0.01, n=15). However, absorbance value, apoptosis rate and migration number of BMSCs in PI3K inhibitor group were contrary to those in CXC-13 group (P<0.01, n=15). Compared with the control group, the protein contents of EGF and VEGF in BMSCs of CXCL-13 group increased significantly (P<0.01, n=15), and the relative expression of Akt and p-Akt increased significantly (P<0.01, n=9). However, the protein content of EGF and VEGF, and the relative expression of Akt and p-Akt in PI3K inhibitor group were opposite.    Conclusion  Through activating PI3K-Akt pathway, CXCL-13 may promote BMSCs paracrine EGF and VEGF proteins, and improve proliferation and migration of BMSCs, as well as inhibit BMSCs apoptosis.
