Telomere stabilization, primarily through telomerase activation, grants cancer cells immortality. Measuring telomere length and telomerase activity in colorectal cancer may aid in prognosis and staging.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Colorectal cancer is a leading cause of cancer death globally.
- Cancer cells achieve immortality through hallmarks like telomere stabilization.
- Telomere maintenance, often via telomerase activation, is crucial for cell immortalization.
Purpose of the Study:
- To explore the role of telomere length and telomerase activity in colorectal cancer.
- To investigate the prognostic implications of telomere maintenance in colorectal carcinoma.
Main Methods:
- Review of existing studies on telomeres and telomerase in cancer.
- Analysis of telomere length in tumor versus non-tumor cells.
- Detection of telomerase activity in colorectal tumors.
Main Results:
- Tumor cells exhibit shorter telomeres compared to non-tumor cells.
- Telomerase activity is prevalent in the majority of colorectal tumors.
- Telomere maintenance and telomerase activity correlate with poor prognosis.
Conclusions:
- Quantification of telomerase activity and measurement of telomere length are valuable.
- These measurements may enhance biologic and prognostic staging of colorectal carcinoma.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
