Moreover, GSEA using the TCGA_SKCM cohort revealed that FUT4 expression is significantly associated with epithelial-mesenchymal transition (EMT) (p = 0.006; FDR = 0.018; NES = 1.9) and melanoma metastasis (p = 0.018; FDR = 0.018; NES = 1.7) signatures (Fig. 4j). The gene discussed is FUT4; the disease is melanoma.
