人非小细胞肺癌细胞中端粒酶活性的检测与研究

目的 研究非小细胞肺癌细胞癌组织中端粒酶活性表达,探讨端粒酶生表达与非小细胞肺癌发生发展的关系。方法 收集经手术及病理证实的非小细胞肺癌４８例标本,１２例肺癌癌旁肺组织、７例非肿瘤病例所取正常肺组织作对照。用端粒酶检测试剂盒检测组织本端粒酶活性。结果 ７５．００％（３６／４８）非小细胞肺癌组织标本检出端粒酶活性,８．３３％（１／１２）癌旁肺组织检出端粒酶活笥,７例非肿瘤标本所取的正常肺组织均未检出

Telomerase activity in human non-small cell lung cancer (NSCLC)

OBJECTIVE: To investigate the activity of telomerase in human non-small cell lung cancer (NSCLC) and the correlation of telomerase activity with the cancer development. METHODS: Totally 48 cases of NSCLC tissues were studied accompanied with 7 cases of normal lung tissues and 12 samples of lung tissues adjacent to the tumor. The telomerase activity was detected using Telomerase PCR ELISA kit. Statistics study included chi(2)-test and the exact probabilities. The significance level chosen was P value less than 0.05 (P < 0.05), and all tests were two-sided. RESULTS: 75% (36/48) of NSCLC tissues possessed the expression of telomerase activity and only 8.33% (1/12) of tissues adjacent to tumor and none of the normal lung tissue enabled to express telomerase activity. The statistical difference was significant (P < 0.05). No significant difference was found between different histological types of NSCLC, however, the frequency of telomerase expression differed significantly between tumors of well/mordeately differentiated and poorly differentiated; stage I and stage II/III. CONCLUSION: Telomerase activity might be a good marker in estimating the occurrence, development and diagnosis of NSCLC.
