Telomerase: a therapeutic target for the third millennium?

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• Telomerase controls cell proliferation by influencing cell senescence, a key biological process.
• The enzyme's expression is strongly correlated with tumor malignancy, differing significantly between cancerous and normal tissues.
• This distinct expression pattern suggests potential for selective targeting in cancer therapy.

Purpose of the Study:

• To review the current state of telomerase research as a potential therapeutic target in oncology.
• To impartially present the advantages and disadvantages of targeting telomerase for cancer treatment.
• To address the question of whether telomerase will be a viable therapeutic target for the future.

Main Methods:

• Review of existing scientific literature on telomerase expression and function in tumors.
• Analysis of the correlation between telomerase activity and malignant properties.
• Discussion of various strategies for developing telomerase inhibitors.

Main Results:

• A strong correlation exists between telomerase expression levels and tumor malignancy.
• Telomerase expression is significantly higher in malignant tissues compared to normal tissues.
• Telomerase inhibitors could potentially offer high selectivity for tumor cells with low normal tissue toxicity.

Conclusions:

• Telomerase is a compelling therapeutic target due to its role in cell proliferation and senescence.
• The clinical relevance of telomerase inhibition, particularly in advanced cancers, requires further investigation.
• Ongoing research focuses on developing diverse telomerase inhibitors for preclinical and clinical evaluation.
