| Outline of Final Research Achievements |
In the present study, we aimed to profile the expression of exosomal microRNAs in CSF and develop a novel biomarker. The exosomal microRNAs were extracted from the CSF of five glioblastoma patients and three non-tumoral volunteers(NPH). Using microRNA microarray, we comprehensively analyzed the 2,006 microRNAs expression profiles.
107 microRNAs (57 up-regulated and 50 down-regulated microRNAs) were aberrantly expressed in glioblastoma patients compared with non-tumoral volunteers. In addition, we defined 3 microRNAs as a Glioma-initiating cells specific exoxomal microRNA that were aberrantly expressed in Glioma-initiating cells and glioblastoma patients compared with neuroral stem cells and healthy volunteers.
