Multiple comparisons between each group identified five genes (BCL2, BHLHE40, MICAL2, TGM2, TPO) that are significantly differentially expressed (P value > 0.05 and a fold change (|FC|) > 2) in any pair of all the subtypes (thyroid carcinoma (TCA), differentiated thyroid carcinoma (DTC), anaplastic thyroid carcinoma (ATC), papillary thyroid carcinoma (PTC), medullary thyroid carcinoma (MTC), follicular thyroid carcinoma (FTC), thyroid non-cancerous tissues (TNC) (Figures 1B–F). This evidence concerns the gene MICAL2 and thyroid cancer, nonmedullary, 2.
