Expression of hTERT mRNA in salivary gland tumors / 实用口腔医学杂志

ABSTRACT

Objective:To investigate the expression of human telomerase reverse transcriptase(hTERT)gene in salivary gland tumors and to study its clinicopathological significance.Methods:In situ- mRNA hybridization method was used to detect the expression of hTERT mRNA in 10 cases of normal salivary gland tissues, 30 of benign salivary gland tumors and 43 of malignant salivary gland tumors.The relationship between hTERT mRNA expression and sex,age, tumor size, location, histologic differentiation of the malignant tumors was analyzed by using ?2 test.Results:hTERT expression was negative in all normal tissues. Positive rate of hTERT mRNA expression was 3.3%(1/30) and 83.7%(36/43) in benign and malignant salivary gland tumors respectively(P0.05).Conclusion:hTERT mRNA expression may be used to distinguish malignant salivary gland tumors from benign.
