Screening of differentially expressed genes and signaling pathway mechanism of melanoma in TCGA database: (A) tumor-associated gene expression changes in melanoma samples from TCGA database; (B) gene expression of melanoma marker genes in TCGA database; (C) top 25 genes with significantly increased or decreased expression in melanoma compared with solid tissue normal samples after screening in TCGA database; (D) the expression levels of MITF and TRY are specifically elevated in melanoma; (E) melanoma signaling pathways in the KEGG database; (F) mutation distribution of KYNU in tumors from TCGA database.
