On the other hand, GSEA was performed with S1PR1 expression-related genes in TCGA BLCA (high S1PR1 associated with poor prognosis) and GSE13507 (low S1PR1 associated with poor prognosis) (illustrated as Figure 5B), and the results of the three GSEAs were visualized using the Enrichment map in Cytoscape (Figure 5C). The gene discussed is S1PR1; the disease is bladder transitional cell carcinoma.
