Furthermore, adding the healthy samples of the genotype-tissue expression (GTEx) dataset to the current control group, we observed significantly overexpressed PSMA7 in tumor samples of diffuse large B-cell lymphoma (DLBC), GBM, pancreatic adenocarcinoma (PAAD), and THYM (Fig. 3B), but not in other tumors, including adrenocortical carcinoma (ACC), CESC, brain lower-grade glioma (LGG), OV, SKCM, testicular germ cell tumors (TGCT), or UCS (Supplementary Fig. S3A) by the gene expression profiling interactive analysis 2 (GEPIA2)42. This evidence concerns the gene PSMA7 and testicular germ cell tumor.
