Subsequently, we combined the expression levels of these target genes (or related genes, such as ST8SIA1 for GD2) in GBM and normal tissues from the Cancer Genome Atlas (TCGA) database (Figure 1B) to identify B7‐H3, IL‐13Rα2, Her2, and GD2 as the target pool for this study (screening criteria: relatively stable protein expression, expression rate >70%, and relatively high gene expression levels). Here, CD276 is linked to glioblastoma.
