The mRNA expression of NR3C1 only showed a negative correlation with that of CD74 in thymoma samples (Pearson’s correlation: −0.32, Spearman’s correlation: −0.31) (Figure 3B), whereas the mRNA expression of FOXP3 showed a positive correlation with that of CD74 (Pearson’s correlation: 0.44, 0.62, 0.60; Spearman’s correlation: 0.44, 0.79, 0.79 in thymoma samples, well-differentiated papillary thyroid carcinoma, and well-differentiated thyroid cancer, respectively) (Figure 3C–E). This evidence concerns the gene FOXP3 and thyroid cancer.
