MicroRNA-374a (miR-374a) has been implicated in several cancers. However, its role in osteosarcoma (OS) remains unclear. Thus the aim of this study was to investigate its expression and role in progression of OS.Quantitative real-time PCR (qRT-PCR) was performed to detect the expression of miR-374a in OS cell lines and tissues. To further understand its role, we restored expression of miR-374a in MG63 cell line by transfection with miR-374a mimics or inhibitors. Effects of miR-374a on cell proliferation on targets were also determined.In the present study, our results showed that miR-374a was significantly up-regulated in both OS cell lines and OS tissues. Over expression of miR-374a markedly accelerated proliferation of OS cells, while its inhibition significantly suppressed cell proliferation. Moreover, Axin2 was identified to be a functional downstream target of miR-374a, and decreased expression of Axin2 could promote OS cell proliferation.Our study suggested that miR-374a functions as an oncogene in OS, and the miR-374a/Axin2 axis might represent a potential therapeutic target for OS intervention.
