Consistent with the UGP2 mRNA expression observed in the TCGA dataset analysis, the pancancer TMA analysis also indicated that the protein expression level of UGP2 in most tumour tissues, including HCC, was lower than that in adjacent nontumour tissues (P < 0.001; Figures 1(b) and 1(c)). Here, UGP2 is linked to hepatocellular carcinoma.
