Among the genes showing significant differences in GPM versus MTC subtypes, the cell cycle regulator TRAF2 was notably downregulated in the TFAM-upregulated group (p = 0.0279, Mann–Whitney test) (Figure 7B) and exhibited a negative correlation with TFAM expression (r = −0.37, p = 0.0009, Spearman correlation test) (Figure 7C). Here, TFAM is linked to medullary thyroid gland carcinoma.
