Since T cell-related signatures (Figure 4A) and pathways (Figure 4B) were enriched for ST3GAL5 overexpression in ccRCC patients, herein relationship between ST3GAL5 expression and tumor-infiltrated CD8+ T cells were further analyzed by TIMER2.0, a web server provides comprehensive analysis and visualization functions of tumor infiltrating immune cells (33). Here, CD8A is linked to neoplasm.
