Background: Telomerase is a specific enzyme that appears to have a key role in cellular senescence and the progression of neoplastic tissue. High telomerase activity has been found in several cancers, but not in most normal and benign tissue. Little is known about the influence of telomerase on the abnormal growth associated with hyperparathyroidism. Objective: To analyse telomerase activity in parathyroid tissue obtained from 29 patients undergoing surgery for primary hyperparathyroidism. Design: Tissue for telomerase activity measurements was collected from six hyperplastic, 20 adenomatous and 22 normal parathyroid glands. Methods: The highly sensitive PCR-based telomeric repeat amplification protocol, TRAP, combined with ELISA, was used to detect telomerase activity in tissue extracts containing 3.0 ╡g protein. Result: Telomerase was not activated in any of the analysed tissue by 3 ╡g protein. Reassay of 12 samples containing 6.0 ╡g protein verified these negative TRAP results. Conclusion: Our findings indicate that telomerase is not a part of the mechanism promoting parathyroid proliferation and the underlying conditions remain to be determined.
