TP53 and neoplasm: The KEGG results revealed that FerRGs were related to tumor and ferroptosis-associated pathways (Figure 2E), especially “ferroptosis” (hsa04216), “FoxO signaling pathway” (hsa04068), “mTOR signaling pathway” (hsa04150), “p53 signaling pathway” (hsa04115), and “mineral absorption” (hsa04978).
