Next, we selected 664 and 3936 DEGs that were highly correlated with Gal9high patients (classified by the mean value of Gal9 mRNA expression) of mesenchymal GBM in the CGGA and TCGA data sets, respectively (Figure 4b,d), and named LGALS9‐correlated genes in mesenchymal (LCGIM) GBM. The gene discussed is LGALS9; the disease is glioblastoma.
