Expression of hTRT and Bax in Papillary Thyroid Carcinoma / 中国医师杂志

ABSTRACT

Objective To study the expressions of human telomerase reverse transcriptase (hTRT) mRNA and Bax protein in different types of papillary thyroid carcinoma (PTC). Methods hTRT mRNA was detected using in situ hybridization, and Bax protein was detected by immunohistochemistry. Results The positive rates of hTRT were 86.21%,68.97%, 93.33%, 96.43% and 41.79% in PTC, papillary microcarcinoma, intra-thyroid carcinoma, extra-thyroid carcinoma and adjacent tumor tissues, respectively. The positive rate of hTRT expression in the cancer tissues was significantly higher than that in the adjacent tumor tissues (P
