Involvement of miR-518c-5p to growth and metastasis in oral cancer.

ABSTRACT: We have previously demonstrated that a stromal cell-derived factor-1 (SDF-1; CXCL12)/CXCR4 system is involved in the establishment of metastasis in oral cancer. Recently, small non coding RNAs, microRNAs (miRNAs) have been shown to be involved in the metastatic process of several types of cancers. However, the miRNAs that contribute to metastases induced by the SDF-1/CXCR4 system in oral cancer are largely unknown. In this study, we examined the metastasis-related miRNAs induced by the SDF-1/CXCR4 system using B88-SDF-1 oral cancer cells, which exhibit functional CXCR4 and distant metastatic potential in vivo. Through miRNA microarray analysis, we identified the upregulation of miR-518c-5p in B88-SDF-1 cells, and confirmed the induction by real-time PCR analysis. Although an LNA-based miR-
