Additionally, the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis confirmed that ‘epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor resistance’, ‘pathways in cancer’, and ‘mammalian target of rapamycin (mTOR) signaling pathway’ are predominantly involved in PTC’s pathogenesis (Figure 2). The gene discussed is MTOR; the disease is cancer.
