Telomere-driven diseases and telomere-targeting therapies

Area of Science:

• Genetics and Molecular Biology
• Cellular Biology
• Aging Research

Background:

• Telomeres, protective chromosome ends, shorten over time, acting as a key aging mechanism.
• Short telomeres impair stem cell function, leading to tissue degeneration and age-associated diseases.
• Mutations in telomere maintenance genes cause telomere syndromes and are linked to cancer.

Purpose of the Study:

• To review the molecular basis of telomere-driven diseases.
• To highlight advancements in preclinical telomere-targeted therapies.

Main Methods:

• Literature review of molecular mechanisms.
• Analysis of preclinical studies using mouse models for telomere-targeted therapies.

Main Results:

• Telomere shortening is implicated in aging, stem cell dysfunction, and chromosomal instability.
• Mutations in telomere maintenance and shelterin genes are associated with various diseases and cancers.
• Preclinical studies demonstrate potential for telomere-targeted therapies.

Conclusions:

• Telomere maintenance is crucial for preventing age-related diseases and cancer.
• Targeting telomere biology offers a promising therapeutic strategy for aging and cancer treatment.
