PTTG1 expression in ACC, BRCA, lymphoid neoplasm diffuse large B-cell lymphoma (DLBC), ovarian serous cystadenocarcinoma (OV), PAAD, skin cutaneous melanoma (SKCM), THYM, uterine carcinosarcoma (UCS), and sarcoma (SARC) was higher than that in normal tissues (all p < 0.01) (Figure 3B and Supplementary Figure S2). Here, PTTG1 is linked to cutaneous melanoma.
