Methods: Immunohistochemistry was used to detect the expression of MCM7 and TACSTD2 in 109 cases of benign and malignant thyroid lesions (69 cases of papillary thyroid carcinoma, 40 cases of nodular goiter and 69 cases of adjacent thyroid tissues). Results: The positive expression rates of MCM7 in the above tissues were 97.1% (67/69), 65.0% (26/40) and 15.94% (11/69), respectively. The positive expression rates of TACSTD2 in the above tissues were 98.55% (68/69), 60.0% (24/40) and 17.39% (12/69), respectively. The positive expression rates of the two proteins in the above three tissues were statistically significant (c2 = 94.5, P c2 = 93.6, P P P = 0.016, < 0.05). Conclusions: MCM7 and TACSTD2 are highly expressed in PTC tissues, and the positive expression of TACSTD2 is positively correlated with tumor diameter, which may be involved in the occurrence and development of PTC. Both of them may provide new molecular biological markers for the diagnosis of PTC.展开更多
