As illustrated in Figure 2, WDR4 expression was upregulated at the advanced stages in ACC, HNSC, KICH, KIRC, LUSC, LIHC, SKCM, and THCA, whereas it was downregulated in advanced KIRP tumours and was constant in advanced BLCA, BRCA, CHOL, COAD, ESCA, LUAD, MESO, PAAD, READ, STAD, TGCT, and UVM. The gene discussed is WDR4; the disease is bladder transitional cell carcinoma.
