摘　　要：OBJECTIVE:To investigate the synergistic effects of polyphyllin Ⅰ(PPⅠ)combined with tumor necrosis factorrelated apoptosis-inducing ligand(TRAIL)on the growth of osteosarcoma cells through downregulating the Wnt/β-catenin signaling pathway.METHODS:Cell viability,apoptosis and cell cycle distribution were examined using cell counting kit-8 and flow cytometry assays.The morphology of cancer cells was observed with inverted phase contrast microscope.The migration and invasion abilities were examined by xCELLigence real time cell analysis DP system and transwell assays.The expressions of poly(adenosine diphosphate-ribose)polymerase,C-Myc,Cyclin B1,cyclin-dependent kinases 1,N-cadherin,Vimentin,Active-β-catenin,β-catenin,p-glycogen synthase kinase 3β(GSK-3β)and GSK-3βwere determined by Western blotting assay.RESULTS:PPⅠ sensitized TRAIL-induced decrease of viability,migration and invasion,as well as increase of apoptosis and cell cycle arrest of MG-63 and U-2 OS osteosarcoma cells.The synergistic effect of PPⅠwith TRAIL in inhibiting the growth of osteosarcoma cells was at least partially realized through the inactivation of Wnt/β-catenin signaling pathway.CONCLUSION:The combination of PPⅠ and TRAIL is potentially a novel treatment strategy of osteosarcoma.
