Targeting telomerase for cancer therapy

Area of Science:

• Oncology
• Molecular Biology
• Biochemistry

Background:

• Telomere maintenance through telomerase reactivation is a key characteristic of cancer cells, conferring replicative immortality.
• Telomerase activity is typically silenced in adult somatic cells, highlighting its potential as a selective cancer target.
• Despite its promise, developing effective telomerase inhibitors has faced significant challenges, with no approved therapies currently available.

Purpose of the Study:

• To review recent advancements in targeting telomerase for cancer therapy.
• To discuss novel strategies including immunotherapies, direct inhibitors, and targeting TERT gene expression.
• To address challenges and future directions for telomerase-directed cancer treatments.

Main Methods:

• Review of current research on telomerase inhibitors and immunotherapies.
• Analysis of emerging approaches targeting TERT promoter mutations and gene expression.
• Discussion of structural models of human telomerase for drug development.

Main Results:

• Prevalent TERT promoter mutations in cancers have renewed interest in targeting telomerase.
• Recent advances in telomerase biology and structural modeling offer new therapeutic avenues.
• Various strategies, including immunotherapies and direct inhibitors, are under investigation.

Conclusions:

• Targeting telomerase holds transformative potential for cancer therapy.
• Overcoming challenges like therapeutic resistance is crucial for clinical translation.
• Continued research and structural insights are boosting the prospects for effective telomerase-directed drugs.
