Expression of telomerase gene and apoptosis related protein in breast carcinoma / 肿瘤研究与临床

Objective To analyze the expression of telomerase and apoptosis related protein,and ex- plore the possible mechanism of breast cancer development.Methods Immunohistochemistry method(SP)was used to detect the expression of hTERT,p53 and bcl-2 in the tissues of 48 cases of human breast cancer and 42 cases of benign lesion in breast.Results The positive rates of expression of hTERT,p53 and bcl-2 in breast cancer were 87.50%,56.25%,54.17%,respectively;Compared with the groups of adjacent non- cancerous and benign lesions,there was a significant difference in three types of tissue(P
