1. Telomerase is a ribonucleoprotein enzyme, which is positively expressed in most malignant tumor cells, while negatively expressed in normal somatic ones.

2. To detect the expression of ribonucleoprotein enzyme telomerases , and explore its significance in diagnosis and prognosis.

3. Telomerase, a ribonucleoprotein enzyme, is a key component in maintaining the development of malignant tumor.

4. Telomerase is a ribonucleoprotein enzyme maintaining the length of the telomeres by adding G-rich repeats to the end of the eukaryotic chromosomes.

5. Telomerase is a ribonucleoprotein enzyme that can synthesizes telomeric DNA, high telomerase activity has been found in many tumors, and telomerase was thought to be a biology sing for diagnosis.

6. Telomerase, a eukaryotic ribonucleoprotein complex , contains both essential RNA and a protein reverse transcriptase subunit.
