[CCR7 silence by siRNA inhibits proliferation, invasion and promotes apoptosis of human MG63 osteosarcoma cells].

Objective To investigate the effect of siRNA-mediated chemokine receptor 7 (CCR7) silence on the proliferation, migration, invasion and apoptosis of human MG-63 osteosarcoma cells. Methods The study designed and synthesized siRNA targeting CCR7 (CCR7-siRNA). After MG63 cells were transfected with CCR7-siRNA, the expression of CCR7 was identified by Western blotting; cell apoptosis was detected by annexinV-FITC/PI double staining combined with flow cemetery; cell proliferation was tested by MTT assay; and cell migration and invasion abilities were examined by Transwell migration/invasion assays.
