NCOA3 and thyroid cancer, nonmedullary, 2: Comparison of the SRC-3 protein abundance among human normal thyroid tissue [Figure 3A-I-a], FTC [Figure 3A-I-b], papillary thyroid cancer (PTC) [Figure 3A-I-c], and ATC [Figure 3A-I-d–f] shows that SRC-3 is clearly higher in ATCs than in normal thyroid tissues, FTC, and PTC [Figure 3A-II].
