MicroRNA‑497 suppresses osteosarcoma tumor growth in vitro and in vivo
2016
It has been demonstrated that microRNA-497 (miR-497) acts as a tumor suppressor and is involved in tumor progression, development and metastasis in several types of cancer. However, little is known about the exact role of miR-497 in osteosarcoma (OS). The aim of the current study was to investigate the potential role of miR-497 in human OS. The role of miR-497 in the growth and survival of OS cells was determined using several in vitro approaches and a nude mouse model. The results demonstrated that exogenous expression of miR-497 in human OS MG63 cells suppressed cell proliferation, colony formation, migration and invasion, and induced cell apoptosis and cell arrest at the G0/G1 phase of the cell cycle. In addition, the results of the in vivo study indicated that restoration of miR-497 inhibited OS tumor growth in a nude mouse model. Overall, the results of the present study identified a crucial tumor suppressive role of miR-497 in the progression of OS, and suggested that miR-497 may be a potential therapeutic agent for the treatment of OS.
