GCG and prostate carcinoma: GO and KEGG enrichment analysis of the shared genes revealed that 24 GO terms were significantly enriched (p < 0.01) (Figure 3D), including 335 DEGs; 6 KEGG pathways were significantly enriched (p < 0.01), namely the FoxO signaling pathway, cell cycle, prostate cancer, autophagy—animals, ferroptosis, and glucagon signaling pathway (Figure 3E), including 40 DEGs.
