FIGURE 2 The expression levels of ST3GALs were correlated with the pathological stage and grade of ccRCC patients. (A) Correlations between mRNA expression levels of ST3GALs and tumor development in ccRCCs from TCGA-KIRC. Upper panel for tumor grade, Grade 1 = 14, Grade 2 = 227, Grade 3 = 206, Grade 4 = 75; Lower panel for tumor stage, Stage I = 265, Stage II = 57, Stage III = 123, Stage IV = 82. (B) Correlations between mRNA expression levels of ST3GALs and tumor development in ccRCCs from GSE73731. Upper panel for tumor grade, Grade 1 = 22, Grade 2 = 90, Grade 3 = 95, Grade 4 = 49; Lower panel for tumor stage, Stage I = 41, Stage II = 12, Stage III = 28, Stage IV =
