examined the expression of CX26 in surgical specimens from 69 cases of papillary thyroid carcinoma (PTC), 11 cases of follicular thyroid carcinoma (FTC), and 22 cases of follicular thyroid adenoma (FTA), and investigated the relationship between CX26 expression and its clinical pathological features. This evidence concerns the gene GJB2 and thyroid gland papillary carcinoma.
