ABSTRACT
As the most common malignant primary bone tumor in childhood, osteosarcoma (OS) maintains a high recurrence, despite the significant improvements in the overall survival rate of high-grade OS patients during the recent decades. Therefore, a novel therapy strategy is required for OS treatment. Recently, various microRNAs (miRNAs or miRs) have been confirmed as deregulated in OS, and the miR-155 dysregulation in OS has been discovered by the microarray analysis. In the present study, the regulation of miR-155 on the OS cell proliferation, migration and invasion on the MG-63 cells was explored in vitro. The miR-155 mimics were found to promote cell proliferation, colony formation, migration and invasion significantly, compared to the control miRNA. An miR-155 inhibitor was also used to evaluate whether miR-155 served as a therapeutic target for OS. The results demonstrated that the miR-155 inhibitor significantly reduced the proliferation, colony formation, migration and invasion of the MG-63 OS cells. Thus, the study confirmed the oncogenic regulation on the OS progression of miR-155, which could serve as a therapeutic target with an miR-155 inhibitor.
