As shown in Fig. 1A, significantly differential expression of STEAP3 was found in 16 cancer types, with 11 tumor types up-regulated (BLCA, CESC, GBM, HNSC, LUAD, LUSC, PCPG, READ, STAD, THCA, and UCEC), and five tumor types down-regulated (BRCA, CHOL, KICH, LIHC, and PRAD). Here, STEAP3 is linked to glioblastoma.
