DEGs among SAAM clusters in STAD and functional enrichment analysis. (A) PCA analysis based on three distinct SAAM subtypes in TCGA. STAD in the cluster A, B, or C subgroup is marked with blue, green, and pink. (B) Venn plots presenting intersection analysis of genes between SAAM subtypes in STAD. (C, D) GO enrichment analysis of intersectant genes among three SAAM clusters. (E, F) KEGG enrichment analysis of intersectant genes among three SAAM clusters.
