Intriguingly, by conjointly analysing the differentially expressed metabolic rate‐limiting enzymes from RNA‐seq data of HCC animal model and TCGA data, 12 transcripts were overlapped (RRM1, SQLE, PCK1, PYGB, G6PD, PLAT, ACSL1, RRM2, UCK2, ASS1, FBP1 and IMPDH1) (Figure 2A). This evidence concerns the gene IMPDH1 and hepatocellular carcinoma.
