ABSTRACT
This study aims to decipher the mechanism of sinomenine in inhibiting platelet-derived growth factor/platelet-derived growth factor receptor(PDGF/PDGFR) signaling pathway in rheumatoid arthritis-fibroblast-like synoviocyte(RA-FLS) migration induced by neutrophil extracellular traps(NETs). RA-FLS was isolated from the synovial tissue of 3 RA patients and cultured. NETs were extracted from the peripheral venous blood of 4 RA patients and 4 healthy control(HC). RA-FLS was classified into control group, HC-NETs group, RA-NETs group, RA-NETs+sinomenine group and RA-NETs+sinomenine+CP-673451 group. RNA-sequencing(RNA-seq) was conducted to identify the differentially expressed genes between HC-NETs and RA-NETs groups. Sangerbox was used to perform the Gene Ontology(GO) function and the Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment. Cytoscape was employed to build the protein-protein interaction(PPI) network. AutoDock Vina and PyMOL were used for molecular docking of sinomenine with PDGFß and PDGFRß. The cell proliferation and migration were determined by the cell counting kit-8(CCK-8) and cell scratch assay, respectively. Western blot was employed to determine the protein level of PDGFRß. Real-time quantitative polymerase chain reaction(RT-qPCR) was carried out to determine the mRNA levels of matrix metalloproteinases(MMPs). The results revealed that neutrophils in RA patients were more likely to produce NETs. Compared with HC-NETs group, RA-NETs group showed up-regulated expression of PDGFß and PDGFRß. Compared with control group, RA-NETs group showed increased cell proliferation and migration and up-regulated protein level of PDGFRß and mRNA levels of PDGFß, PDGFRß, MMP1, MMP3, and MMP9(P<0.05). Compared with RA-NETs group, RA-NETs+sinomenine group presented decreased cell proliferation and migration and down-regulated protein and mRNA level of PDGFRß and mRNA levels of MMP1, MMP3, and MMP9(P<0.05). Compared with RA-NETs+sinomenine group, the proliferation ability of RA-NETs+sinomenine+CP-673451 group decreased(P<0.05). The findings prove that sinomenine reduces the RA-NETs-induced RA-FLS migration by inhibiting PDGF/PDGFR signaling pathway, thus mitigating RA.
