Abstract Accumulating studies revealed that the expression levels of several miRNAs are up or down-regulated in osteosarcoma (OS). The aim of this study was to investigate the functional significance and molecular of the let-7g in OS cells. The expression levels of let-7g was significantly down-regulated in OS cell lines U2-OS and HOS cell compared to osteoblast cell lines HOB cell. Moreover, bioinformatic prediction suggested that Aurora-B, which is overexpressed and functions as an oncogene in OS cells, is a putative target gene of let-7g. Using mRNA and protein expression analysis and luciferase assays, we further identified let-7g directly regulated Aurora-B expression in OS cells. Functional investigation revealed both restoration of let-7g and silencing Aurora-B induce cell apoptosis and suppressed cell viability, migratory and invasive ability in OS cells. Finally, we found that silencing Aurora-B in OS cells could partly dampen anti-let-7g mediated tumor promotion. Thus, our findings suggested that let-7g inhibits OS cell malignant phenotype at least partly through targeting Aurora-B. Targeting of let-7g and Aurora-B may be a novel therapeutic strategy for treating OS.
