- Healthspan Pharmacology-
Consumption of natural products claimed to have anti-aging properties is high in the US population. While some studies show an impact on age-related diseases such as cancer, heart disease and neurodegenerative disorders, there are large gaps in our knowledge about the mechanisms through which these products modulate aging.
- Screening Candidate Anti-Aging Compounds -
We need appropriate methodologies to study the pharmacology of aging in model species, if experimental findings with such systems are to be extrapolated to the treatment of human aging. Using Drosophila as our model system, we have developed a number of bioassay to address this issue. These assays constitute a general testing protocol for anti-aging pharmacology.
- Molecular Mechanisms of Anti-Aging -
We hypothesize that botanicals extend life span and enhance health span by modulating one or more of the major pathways of aging: mitochondrial bioenergetics/oxidative stress, insulin signaling, sirtuins, and target of rapamycin (TOR). Using cell culture, Drosophila and mice as our model systems, we use standardized botanical extracts to address the following questions: 1) Do the botanicals that attenuate aging also improve health span? 2) Do these botanicals alter mitochondrial function, reduce free radicals, and/or protect against oxidative stress?; and 3) Do these botanicals act through the major pathways or proteins associated with aging?
