Abstract Osteosarcoma (OS) is a primary high-grade malignant bone neoplasm, and the prognosis of OS remains poor due to
early metastasis. Leptin plays an essential role in tumorigenesis, but the role of leptin in the development of OS is still not fully
understood. In this study, we used a human osteosarcoma MG-63 cell line as an experimental model. MG-63 cells were treated
with leptin, and cell proliferation, apoptosis, adhesion, invasion, and gene expression, were evaluated. The results showed that
leptin promoted proliferation, decreased adhesion, suppressed apoptosis, and promoted invasion, of MG-63 cells. Moreover,
the expression of SIRT1 was upregulated in MG-63… More >
