What is the Origin of Telomere Maintenance Proxies?

This concept emerges from the groundbreaking research in telomere biology, which established telomere shortening as a key molecular clock of cellular senescence and aging. 'Proxies' are utilized because direct, longitudinal telomere length measurement is complex and costly, making surrogate markers necessary for routine clinical monitoring. The term links fundamental aging science to clinical practice.

What is the Mechanism of Telomere Maintenance Proxies?

Relevant proxies include markers of oxidative stress (e.g., 8-OHdG), chronic inflammation (e.g., high-sensitivity CRP), and nutrient status (e.g., folate, B12), all of which are known to influence telomere attrition rates. Additionally, optimizing growth hormone and sex hormone levels can indirectly support telomere integrity by promoting cellular repair and reducing systemic stress. The mechanism is based on the strong correlation between these systemic factors and the cellular environment required for effective telomere maintenance.

Telomere Maintenance Proxies

Meaning

Quantifiable biomarkers and physiological indicators used in clinical practice that indirectly reflect the health, length, and functional maintenance status of telomeres, the protective caps on the ends of chromosomes. While not direct measurements of telomerase activity, these proxies provide non-invasive, accessible data on the rate of cellular aging and genomic stability. They serve as actionable indicators for assessing the impact of longevity interventions.
