Telomerase therapeutics for degenerative diseases

Area of Science:

• Molecular Biology
• Genetics
• Gerontology

Background:

• Telomerase is active in early development but repressed in adult somatic cells.
• This repression leads to gradual telomere shortening with age.
• Short telomeres are linked to increased risk of heart disease, stroke, infection, and specific genetic disorders.

Purpose of the Study:

• To explore the role of telomere length and telomerase activity in aging and disease.
• To investigate the therapeutic potential of telomerase activation for degenerative conditions.

Main Methods:

• Review of epidemiological and genetic studies on telomere length and disease.
• Analysis of cellular and animal models of telomere dysfunction and telomerase activity.

Main Results:

• Short telomeres correlate with increased mortality from cardiovascular events and infections.
• Mutations in telomerase components cause Dyskeratosis congenita, characterized by premature aging and bone marrow failure.
• Telomerase activation in vitro and in vivo extends cell lifespan, enhances stress resistance, and prevents age-related tissue damage.

Conclusions:

• Telomere attrition is a significant factor in aging and disease pathogenesis.
• Pharmacological activation of telomerase presents a promising therapeutic strategy for a wide range of chronic and degenerative diseases.
