Bioinformatics analysis revealed that the expression of CCL5, TGFβ2, VEGFβ, and IL33 was much higher in both LGG and GBM tissues than in the corresponding normal tissues (http://ualcan.path.uab.edu/, Figs. 5G and S6A–F), and was closely correlated with prognosis. This evidence concerns the gene VEGFB and glioblastoma.
