UGP2 has potential roles in fatty acid metabolism. (a) KEGG functional enrichment analysis showing the potential mechanism of UGP2 in HCC. (b) GSEA of the relationship between low UGP2 expression and genes associated with fatty acid metabolism. (c–g) The scatter plots show that UGP2 expression is markedly correlated with genes involved in fatty acid metabolism. UGP2: uridine diphosphate-glucose pyrophosphorylase 2; KEGG: Kyoto Encyclopedia of Genes and Genomes; HCC: hepatocellular carcinoma.
