title: Knockdown of SALL4 Inhibits Proliferation, Migration, and Invasion in Osteosarcoma Cells.
abstract: Sal-like protein 4 (SALL4) is a zinc finger transcription factor that has been reported to be aberrantly expressed in several human malignancies and identified as an oncogene. However, the potential role of SALL4 in osteosarcoma remains to be elucidated. In this study, we explored the biological functions of SALL4 in osteosarcoma. We found that SALL4 was overexpressed in osteosarcoma tissues and cell lines. Knockdown of SALL4 inhibited osteosarcoma cell proliferation, migration, and invasion in vitro. In addition, SALL4 knockdown suppressed osteosarcoma growth and metastasis in vivo. We also showed that SALL4 knockdown decreased the protein expression of Wnt3a and β-catenin in osteosarcoma cells. Taken together, our study showed that SALL4 plays an important role in regulating the proliferation, migration, and invasion of osteosarcoma cells. Thus, SALL4 may represent a potential therapeutic target in the treatment of osteosarcoma.
