The Genetic and Epigenetic Signatures of Translational Aging Laboratory Testing (GESTALT)
National Institute on Aging (NIA)
Summary
Background: \- Biomarkers are substances in people s blood and tissues. They help researchers understand diseases and signs of aging. Scientists want to do more research on biomarkers to find ways to improve quality of life in old age. Objective: \- To learn more about biomarkers and their relationship to aging. Eligibility: \- Adults at least 20 years old who weigh at least 110 pounds and have a body mass index below 30. They must agree that their genetic samples can be collected, studied, and stored. Design: * Participants will be screened with medical history, physical exam, EKG and blood and urine tests. * Participants will have 3-day visits. They will return every 2 years. * All visits include: * Blood and urine collection * Physical performance tests * Health questionnaires * Memory and problem-solving tests * Magnetic Resonance Imaging (MRI) and Computerized Tomography (CT) scans. * Muscle metabolism/ exercise tests * Taste strips * Muscle and/or skin biopsies/ red light therapy * Retinal imaging/ eye tracking * Sleep study * ODD visits also include: * Cytapheresis * Bone marrow aspirate * EVEN visits also include: * Hyperglycemic CLAMP * Lumbar Puncture (LP) * Continuous Glucose Monitor (CGM)
Description
Under the assumption that aging is caused by dysfunction of specific biological mechanisms, it is reasonable to hypothesize that slowing aging should delay the onset of chronic diseases that typically affect older persons and improve their longevity and quality of life. Indeed, there is emerging evidence that factors associated with premature mortality are also involved in multiple pathologic conditions typical of aging. There is evidence that the study of aging and longevity requires a more comprehensive analysis of biological, environmental and phenotypic changes that occur with aging and ho…
