As shown in Figure 1A, no PSMA expression could be observed in vessels of normal brain tissues, while PSMA was faintly expressed in endothelium of vessels in 5/60 GBM tissues, moderately expressed in 15/60 GBM tissues and highly expressed in 40/60 GBM tissues (Figure 1A). This evidence concerns the gene FOLH1 and glioblastoma.
