As shown in Figure 5A, the expression levels of STEAP2 in the tumor tissues of breast invasive carcinoma (BRCA), GBM, kidney chromophobe (KICH), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), thyroid cancer (THCA), uterine corpus endometrial carcinoma (UCEC) (p < 0.001), and bladder cancer (BLCA) (p < 0.01) were lower than those in the corresponding control tissues. The gene discussed is STEAP2; the disease is neoplasm.
