| Outline of Final Research Achievements |
We evaluated the correlation between the MES score and expression of HDAC and histone demethylase genes and found that the MES score correlated only with HDAC7 expression (correlation coefficient 0.5165; p < 0.0001). To determine HDAC7 protein expression in GBM tissues, we selected and immunostained 10 GBM tissues with high MES scores (>6) and 11 with low MES scores (<2) by using a cutoff of the mean ± SD of the MES score. Immunohistochemical results demonstrated a higher positive immunostaining in the high MES score group than in the low MES score group (Mann-Whitney test, p = 0.0002).We showed that mesenchymal gene expression in glioblastoma is associated with HDAC7 gene and protein expression; thus, HDAC7 might be a novel therapeutic target for glioblastoma.
