CXCR4-mediated osteosarcoma growth and pulmonary metastasis is suppressed by MicroRNA-613.

ABSTRACT: Osteosarcoma is the most common primary bone malignancy. Recently, studies showed chemokine receptor 4 (CXCR4) played a critical role in osteosarcoma. However, the regulation of CXCR4 is not fully understood. microRNAs are short, non-coding RNAs that play an important roles in post-transcriptional regulation of gene expression in a variety of diseases including osteosarcoma. miR-613 is a newly discovered miRNA and has been reported to function as a tumor suppressor in many cancers. In this study, we confirmed that both Stromal Cell-Derived Factor (SDF-1) and CXCR4 could be prognostic markers for osteosarcoma. Meanwhile this study found that SDF-1/CXCR4 pathway regulated osteosarcoma cells proliferation, migration and reduced apoptosis. Besides, we demonstrated that miR-613 was significantl
