KEGG enrichment analysis showed 43 DEGs were annotation to 50 pathways, and 8 were significantly enriched (p < 0.05), namely “phagosome”, “lysosome”, “other glycan degradation”, “notch signaling pathway”, “autoimmune thyroid disease”, “small cell lung cancer”, “thyroid hormone synthesis”, and “MicroRNAs in cancer” (Figure 5D). This evidence concerns the gene TG and cancer.
