Researchers investigate targeting aging biology to extend health span
- Scientists are investigating whether aging itself can become a primary target of medicine, shifting away from treating chronic conditions individually after they develop.
- Medical researchers argue that targeting the root biology of aging could simultaneously address multiple conditions like diabetes, cardiovascular disease, and cancer.
- Researchers are analyzing biological data beyond chronological age to understand how a body is aging.
Scientists are investigating whether aging itself can become a primary target of medicine, shifting away from treating chronic conditions individually after they develop. Researchers are examining whether biological changes associated with aging can be measured and influenced to extend health span, meaning the years of life spent in good health rather than just chronological lifespan.
Targeting Biological Mechanisms Over Individual Diseases
Medical researchers argue that targeting the root biology of aging could simultaneously address multiple conditions like diabetes, cardiovascular disease, and cancer. Speaking to CNN, Albert Einstein College of Medicine longevity research director Nir Barzilai in New York City explained that these conditions are fueled by a unique biological aging process. Instead of waiting for illnesses to emerge, medicine could eventually intervene in the underlying processes. According to Daniel Belsky, an associate professor of epidemiology at the Columbia University Mailman School of Public Health and the Robert N. Butler Columbia Aging Center, this premise is still unproven in humans, though converging data has successfully prompted funding for clinical evaluation. In laboratory experiments with organisms from roundworms to mice, interventions including medicines, exercise, and calorie restriction have successfully slowed cellular changes and extended life. Belsky stated that clinical trial evidence for extending human health span through this biology does not yet exist, but the field is advancing toward human trials.
Tracking Biological Markers and Multi-Omic Data
Researchers are analyzing biological data beyond chronological age to understand how a body is aging. One approach examines epigenetics, which involves chemical tags known as methyl groups bonded to DNA that track the passage of time. Belsky’s Finding Aging Biomarkers by Searching Existing Trials project collects multi-omic data combining proteins, metabolites, and epigenetic marks on white blood cells. The goal is identifying biological indicators that respond to interventions, though Belsky noted that the connection between manipulating these biomarkers and extending healthy lifespan remains unestablished. Because outcomes can take decades to appear, trials might need to follow participants for two or three decades. Consequently, researchers want to use biomarkers as surrogate endpoints to reliably predict long-term health outcomes.
Emergence of Longevity Clinics and Regulatory Frameworks
Longevity clinics are opening to provide conventional medical assessments alongside wider testing suites. The Mayo Clinic launched its Healthy Longevity Clinic in 2023, and Singapore’s National University Health System established a similar program combining assessments with personalized lifestyle or medical interventions. Amid this growth, some scientists emphasize the need for better regulation. In Abu Dhabi, the Department of Health established a licensing framework for Healthy Longevity Medicine Centers in October 2024, creating a clinical category and setting operating standards for facilities.
