We found that the upregulated genes in HFGC of both Thai HCC and iCCA were significantly enriched with cell cycle and DNA replication process-related genes, while immune response-related genes were down-regulated (Fig. 3C–E and Table S2), with similar results found in TCGA HCC (Fig. S10A,B and Table S3). Here, PRRT2 is linked to hepatocellular carcinoma.
