FIGURE 1 The transcription levels of six ST3GAL members in ccRCC and normal kidney tissues. (A) Differential mRNA expression analyses in ccRCC on Oncomine platform. The numbers of ccRCC datasets with signi fi cant different expression levels of ST3GAL family members were shown (blue, downregulated; red, upregulated). (B-D) Comparison of the mRNA expression levels of ST3GAL family members in ccRCCs (T) and normal kidneys (N) in GSE66272 ( B ; T = 27, N = 27), GSE53757 ( C ; T = 72, N = 72) and TCGA-KIRC ( D ; T = 530, N = 72). (E) Comparison of the mRNA expression levels of ST3GAL family members in paired normal (N) and ccRCCs (T) tissues (n=72). ***, p < 0.001; ns, p ≥
