HROB and testicular germ cell tumor: By applying a strict threshold (r > 0.35, p < 0.001), we identified positive correlations between HROB expression and mRNAsi of 15 tumor types including BLCA, BRCA, CHOL, COAD, ESCA, HNSC, LUAD, LUSC, READ, SARC, SKCM, STAD, testicular germ cell tumors (TGCTs), thymoma (THYM), and UCEC (Figure 6).
