Comparative biology and non-traditional approaches for basic aging research for facilitating translational studies

AbstractAs humans, we aspire to healthy aging and ideally reaching our maximal lifespan. That, however, requires optimizing resilience to stressors and minimizing exposure to factors that accelerate aging. Understanding the complexities of aging processes involves characterizing the causal bases of physical, physiological, and cognitive deficits that accumulate over time, eventually culminating in reduced functionality and decreased resistance to disease and environmental stressors. Both the progression of age-related conditions and onset of diseases are affected by environmental stressors; however, the basis for increased susceptibility remains poorly understood. Furthermore, the actions of some environmental stressors, such as endocrine disruptors, can alter both developmental and aging processes, contributing to lifelong issues with inflammatory and neurodegenerative conditions. This manuscript focuses on the comparative biology and evolution of aging and longevity. The status of an array of animal models and potential for specific geroscience translational applications is addressed by asking these questions.What animal models are currently available for aging and translational geroscience?What are the key roadblocks and barriers for studies of healthy aging, and how might specific animal models be useful? Are research tools available?Which vertebrate animal models can specifically address targeted questions in human aging processes?Can information be synthesized for a ran...
