端粒酶 (Ｔｅｌｏｍｅｒａｓｅ)是一种核糖核蛋白 ,依赖酶分子中的ＲＮＡ模板 ,通过逆转录合成染色体末端的端粒。近年来研究证实 ,端粒酶与细胞衰老及细胞分裂过程密切相关 ,尤其在恶性肿瘤组织中活性异常高。因此通过测定肿瘤组织、癌旁细胞及脱落细胞等端粒酶活性 ,可用于癌 Telomerase is a type of ribonucleoprotein that relies on RNA templates in enzyme molecules to synthesize telomeric telomeric ends by reverse transcription. In recent years, studies have confirmed that telomerase and cell senescence and cell division process are closely related, especially in malignant tumor tissue abnormally high activity. Therefore, by measuring the tumor tissue, adjacent cells and exfoliated cells and other telomerase activity, can be used for cancer
