IFNG and cancer: KEGG enrichment analysis showed that significant resisters of IFN-γ were enriched in the mitogen-activated protein kinases (MAPKs) signaling pathway and pathways in cancer in HepG2 cells, and were enriched in the ribosome, ribosome biogenesis in eukaryotes and selenocompound metabolism pathways in SK-Hep-1 cells (Fig. 1d, e).
