KEGG analysis showed that the DEGs between tumor tissues and peritumor tissues of HCC patients from the TCGA-LIHC dataset were enriched in several ferroptosis-related pathways, such as p53 signaling pathway, fatty acid metabolism, fatty acid degradation, arachidonic acid metabolism, and alanine, aspartate, and glutamate metabolism (Figure 1C). This evidence concerns the gene TP53 and hepatocellular carcinoma.
