As shown in Fig. 3A, patients with high SLC31A1 expression have a shorter OS than those with low SLC31A1 expression in cases of ACC (p = 0.0025), BLCA (p = 0.0031), mesothelioma (MESO) (p = 3.5e−05), and skin cutaneous melanoma (SKCM) (p = 0.027). This evidence concerns the gene SLC31A1 and adrenal cortex carcinoma.
