CAST and testicular germ cell tumor: Figure 2 demonstrates the CAST expression in transcripts per million (TPM). Glioblastoma (GBM), pancreatic adenocarcinoma (PAAD), and stomach adenocarcinoma (STAD) showed prominent CAST expression, while testicular-germ-cell tumors (TGCTs), uterine corpus endometrial carcinoma (UCEC), and uterine carcinosarcoma (UCS) involved less. The CAST expression in different tissues is shown in Table 1.
