ABSTRACT
Objective Study of the molecular mechanisms of metastasis is still the research focus for osteosarcoma (OS) prevention. This study investigates the mechanism of valosin-containing protein (VCP) promoting OS metastasis in vitro through autophagy and epithelialmesenchymal transition (EMT). Methods Different cell lines of osteosarcoma (143B and MG63) were adopted in this study. The level of VCP expression in osteosarcoma cells was changed, and the level of autophagy and the progression of the epithelialmesenchymal transition (EMT) were observed. Then autophagy and EMT in OS cells were changed artificially, and proliferation and migration ability were observed. Results The expression of LC3II/I was decreased, but the insolubilized P62 protein expression was increased in the VCP inhibiting group and the autophagy inhibitor treatment group. Simultaneously, E-cadherin protein expression increased while N-cadherin protein expression decreased in the VCP inhibiting group but increased in the TGF-β1 treatment group. In addition, suppressing VCP can cause a decrease in Transforming Growth Factor β1 (TGF-β1), smad2, smad3, phosphorylated smad2 (p-smad2), and phosphorylated smad3 (p-smad3). Autophagy inhibitors and agonists have no significant effect on the migration and invasion of OS cells but can significantly affect the ability of cells to resist anoikis. EMT inhibitors and agonists have a proportional effect on the migration and invasion of OS cells. Conclusion VCP is likely to promote the migration and invasion of OS cells by inducing EMT, possibly via TGF-β1/smad2/3 signaling pathway. In this process, VCP-mediated autophagy may contribute to successful distant metastasis of tumor cells indirectly (AU)
