Summary
Telomerase activity was detected in 90% of oral squamous cell carcinoma tumors, suggesting its role in cancer development. This enzyme may serve as a valuable molecular marker for oral cancer.
Area of Science:
- Oncology
- Molecular Biology
Background:
- Telomerase, a riboprotein, is associated with cellular immortality.
- Telomerase is implicated in the development of various cancers.
Purpose of the Study:
- To investigate telomerase expression in oral squamous cell carcinoma (OSCC).
- To assess the potential of telomerase as a diagnostic marker for OSCC.
Main Methods:
- The telomeric repeat amplification protocol (TRAP) was used to detect telomerase activity.
- Twenty OSCC tissue samples and 20 adjacent normal mucosal samples were analyzed.
- K562 (positive control) and Hs21Fs (negative control) cell lines were utilized.
Main Results:
- Telomerase activity was found in 90% of OSCC tumor samples.
- 35% of adjacent normal mucosal samples also exhibited telomerase activity.
- Significant differences in telomerase activity were observed between different stages of OSCC (T1/T2 vs. T4).
Conclusions:
- High prevalence of telomerase activity in OSCC supports its role in tumorigenesis.
- Telomerase may function as a molecular marker for oral cancer, warranting further investigation.
