| Outline of Final Research Achievements |
In this study, we examined the miRNA association involved in the mGluR5 expression using oral cancer cells, B88, which express functional CXCR4 and exhibit highly metastatic potentials. We examined the metastasis-related miRNAs in SDF-1 stimulated B88 cells by use of a miRNA microarray analysis. Consequently, we isolated miR-30 family which has predictive binding sites in 3'-UTR of mGluR5 mRNA in silico analysis. Among these miRNAs, we confirmed the downregulation of all miR-30 family in SDF-1 stimulated B88 cells by the real-time PCR analysis. Next, we transfected these miR-30 families in SDF-1 stimulated B88 cells. We confirmed the downregulation of mGluR5 by the miR-30a-5p and miR-30c-5p overexpression. These results indicated that SDF-1/CXCR4 system might regulate the metastases of oral cancer by the upregulation of mGluR5 via downregulation of miR-30 family.
