My 101

It is projected that by 2035, the number of people in the US over the age of 65 years old will be greater than the number of people below 18 years old. This projection illustrates the massive shift in the United States to an aged population. With the aging population comes challenges because of the increase costs and burdens of the diseases that accumulate with age. In our lab, we study the aging process in order to understand how to make people age slower. Our goal is not to make it possible to live 150 years, but rather to extend the period spent free of disease. In other words, rather than increase the lifespan, we aim to increase the healthspan. Of particular interest to our lab is how to maintain muscle, which is important for maintaining independence and a healthy metabolism.

In our laboratory we use models that live longer than they should, to understand what gives rise to increased healthspan. We focus on how to maintain proteins in a “young” state so that cells and tissues can continue to function normally and absent of disease. Of particular interest are mitochondria since these cellular organelles seem to be central to the aging process. Our research seeks to determine if we can maintain the quality of proteins in mitochondria to maintain overall health. In a tissue like muscle, it is our hope that maintaining mitochondria will help preserve muscle function with age. Importantly, it is always our goal to take what we learn in our laboratory experiments and translate them into human treatments that improve human healthspan.

Research

Maintaining proteostasis with aging: The Geroscience Initiative identified proteostasis as one of the seven “pillars” of aging research. Proteostasis refers to the processes that maintain proteome fidelity. My research focuses on the biosynthesis and turnover components of proteostasis. In this regard, we make direct measures of these dynamic processes, not markers or indicators, which has led to important insight into shared characteristics of slowed aging. By using stable isotopes to simultaneously measure both protein synthesis and DNA synthesis in vitro and in vivo we have made two discoveries: 1) mitochondrial proteins are selectively translated in slowed aging models, and 2) when accounting for cell proliferation, the turnover of proteins in existing cells is increased, not decreased. These findings are repeatable in several slowed aging models and slowed aging treatments.
Stress resistance and slowed aging: Like proteostasis, The Geroscience Initiative identified stress resistance as a “pillar” of aging research. My interest in stress resistance spurred from our work with the transcription factor Nrf2. From this work, we proposed a Nrf2 activator to the NIA Interventions Testing Program (ITP), which increased median lifespan in male mice. We followed this up with the proposal of a second-generation Nrf2 activator, which is currently in testing. We have used these Nrf2 activators both as a means to understand the aging process as well as treat it.
Translation of treatments to slow aging: It is my goal to translate our more basic science into potential human treatments to slow aging. We do this using unique animal models and with clinical trials in humans. My work in humans has focused either on exercise, metformin, or Nrf2 activation. More specifically, we have investigated the efficacy of these treatments to slow age-related declines in skeletal muscle mitochondrial function and skeletal muscle mass. For example, some in the aging field are pushing metformin to be the first drug used to treat aging. We have data both in support and against such use. It is clear to us that the field needs more evidence before pushing such an expensive clinical trial.
Approaches: Stable isotopes and mass spec are key features of my research program. In this regard, I consider our lab a leader in the use of D2O to measure in vitro and in vivo biosynthetic processes. We are working on methods to expand these approaches in order to continue to improve measurements of kinetic processes. I also have extensive experience in using stable isotopes for the assessment of metabolic flux. In combination these approaches allow us to explore the interface between protein and energetics.
