| Outline of Final Research Achievements |
In this study, we aimed to identify glioma specific microRNAs as novel therapeutic tool and biomarker. Exosomal microRNA were extracted from serum of glioblastoma (GBM) patients and healthy volunteers. We comprehensively analyzed more than 2,000 microRNAs expression profiles and cross-checked the microRNAs expression profiles from both patient serum and medium of glioma-initiating cell (GIC).
In first analysis of 16 samples, 112 microRNAs were aberrantly expressed in GBM patients compared with health volunteers. In addition, we defined 69 microRNAs in final analysis of 29 samples.
Finally, we identified 2 microRNAs, miR-30c and miR-128, as glioma specific microRNA that were significantly expressed in GIC and GBM patients.
