From biological perspective, MAPK signalling, Extracellular matrix, Focal adhesion, ErbB signalling, Apoptosis, TGF-beta signalling, Glutamatergic synapse and Toll-like receptor signalling pathways were found as significantly altered in our analysis, hence these pathways may be the core pathways that are involved in thyroid cancer. Here, EGFR is linked to thyroid gland carcinoma.
