| Abstract |
Background and Objectives: The expression of telomerase, a ribonucleoprotein complex, has been detected in tissues from many human cancers, but not in the majority of normal tissues except germ cell. It is believed that the activation of telomerase is linked to celluar immortality and may playa role in tumorigenesis. Human telomerase reverse transcriptase (hTERT) has been identified as a putative catalytic subunit of human telomerase and its expression is closely correlated with telomease activity. We studied the expression of hTERT in head and neck squamous cell carcinoma (HNSCC) and resection margin by immunohistochemistry for hTERT and evaluate the correlation between hTERT expression and clinical data in HNSCC.
Materials and Methods: We performed a immunohistochemistry in 17 cases of HNSCC and 10 cases of resection margins, histologically normal. The correlations between the hTERT expression and the clinical data in HNSCC were analyzed.
Result: hTERT immunoreactivities were detected in 14 of 17 (82.4%) HNSCC, 1 of 10 (10%) resection margin. No correlation was observed between clinical data and hTERT expression in HNSCC.
Conclusion
hTERT is activated in HNSCC and its expression is independent from clinical data of patients. |
