ObjectiveTo observe the influence of LM609/AMD3100/CCX754 on chemotactic capability, cytoskeleton, and expression of integrin αvβ3 protein of squamous cell carcinoma of head and neck (SCCHN) cell line PCI-13 induced by stromal cell-derived factor-1 (SDF-1)in vitro.MethodsMigration assays, flow cytometry and immunofluorescence were used to observe the effects of SDF-1, LM609, AMD3100 and CCX754 on the migration, cytoskeleton and the expression of integrin αvβ3 protein in PCI-13 cell lines.ResultsSDF-1 favored PCI-13 cell migration, pseudopod formation, and activities of integrin αvβ3 phosphorylation. LM609, AMD3100, and CCX754 blocked all these effects.ConclusionSDF-1 can induce metastatic SCCHN by integrin αvβ3-CXC chemokine receptor (CXCR) 4/CXCR7 axi. LM609, AMD3100, and CCX754 and can reduce the regulation of SDF-1 on SCCHN activity.
