Figure 4: Gene expression of new candidate markers (NPNT and MLEC) in normal thyroid tissue and PTC. Gene expression of NPNT was significantly higher in PTC when compared with normal thyroid tissue. However, expression of MLEC showed no significant differences (Normal: normal thyroid tissue, PTC: Papillary thyroid carcinoma, * 𝑃 < 0 . 0 5 , NS: not significant, Bar: 1 SD).
