Using data collected from GTEx, normal tissues were used as controls, and we found that the expression levels of GRWD1 in diffuse large B-cell lymphoma (DLBC), glioblastoma multiforme (GBM), pancreatic adenocarcinoma (PAAD), testicular germ cell tumors (TGCTs), and thymoma (THYM) tissues were higher than those in adjacent normal tissues (Figure 1(b)). This evidence concerns the gene GRWD1 and glioblastoma.
