| Outline of Final Research Achievements |
Distinguishing between GIST and benign leiomyoma among gastrointestinal submucosal tumors is clinically significant. We focused on miRNAs, not invasive tissue collection methods, but whether they can differentiate both by blood alone. As a result of focusing on miRNA contained in exosome in serum, there was a significant difference in expression of 7 molecules of miRNA. Of the 7 molecules, we identified three molecules of miRNA that had significant differences in the miRNA expression of GIST tumor tissue and normal tissue. Accordingly, we are going to further investigate whether these molecules would work as a target of quantification by real-time qPCR.
