FIGURE 5 ST3GAL5 was positively correlated with CD8 + T cell in fi ltration in ccRCC. (A) The correlations between ST3GAL5 mRNA expression and in fi ltration fractions of different immune cells by xCell in TCGA-KIRC dataset using Pearson correlation analysis (n = 530). (B) The correlation between ST3GAL5 mRNA expression and the in fi ltration level of CD8 + T cell by xCell, MCP-counter, quanTIseq and EPIC algorithms in ccRCC samples from TCGA-KIRC (n = 533). (C) The correlation between ST3GAL5 mRNA expression and CD8 + T cells density in tumor center (left panel) and in tumor margin (right panel) in ccRCC sample from Braun DA cohort
