Professional Interests

Dr. Huffman is an Assistant Professor of Medicine and Molecular Pharmacology, Co-Director of the Einstein Healthy Aging Physiology Core, and Member of the Einstein Aging Center, Cancer Center, and Diabetes Research Center at the Albert Einstein College of Medicine. Dr. Huffmanâ€™s research is focused on three areas:

The biology of aging: role of IGF-1 signaling
Central insulin and IGF-1 signaling
Role of obesity and aging on cancer risk

1) The biology of aging: role of IGF-1 signaling â€“ I am primarily interested in understanding the interplay between endocrine and metabolic systems with aging and age-related diseases. There is a clear link between aging and metabolism across species. In mammalians, aging is characterized metabolically by accretion of visceral fat, insulin resistance, dyslipidemias and metabolic inflexibility. This dysregulation in metabolism has been linked to increased risk for numerous age-related diseases and accelerated aging. Likewise, growth factors and body size have been closely tied to lifespan. Indeed, dwarf mice live longer than normal mice, small dogs live longer than large dogs, and ponies live longer than thoroughbreds. This phenomenon is believed to be attributed to a reduction in growth hormone (GH)/insulin-like growth factor-1 (IGF-1) signaling, and less signaling through this axis has been has been linked to improved longevity in model organisms. Furthermore, in humans, high IGF-1 levels are associated with increased cancer risk, but are paradoxically linked with protection from cardiovascular disease, type 2 diabetes and osteoporosis. Thus, the relevance of IGF-1 to aging in humans remains unclear.

Relevant to this paradox, we have recently uncovered novel, beneficial effects of centrally-acting IGF-1 on peripheral metabolism. Furthermore, we have found that as compared to central insulin treatment, central IGF-1 replacement in old, insulin-resistant rats, more effectively restores peripheral insulin action. This has led us to hypothesize that optimally modulating IGF-1 signaling to promote healthy aging and longevity in humans may require shifting the balance of IGF-1 from the periphery to the central nervous system (CNS) in order to maximize the 'good' effects of IGF-1, while minimizing its 'bad' effects on cancer in the periphery. We are currently testing this hypothesis in animal models using a combination of genetic and pharmacologic approaches, combined with several state-of-the-art strategies to evaluate healthy aging in these animals. We are specifically evaluating the potential of IGF-1 receptor (IGF-1R) antibodies, currently used in clinical trials to treat cancer, as a pharmacologic strategy to reduce peripheral (but not central) IGF-1R signaling in hopes that this may serve as a translational tool for treating some manifestations of aging in humans, thus ""bridging the gap"" between basic biological discovery and human therapeutic strategy.

2) Central insulin and IGF-1 signaling â€“ A second area involves understanding the mechanism(s) whereby insulin and IGF-1 signaling in the brain control peripheral metabolism. Ongoing studies have uncovered novel similarities and differences between insulin and IGF-1 in regards to their ability to regulate glucose metabolism via the CNS. These studies involve tandem central infusion of peptides and/or inhibitors during a euglycemic clamp in awake, unstressed animals. These studies thus far seem to suggest a potentially important role for insulin receptor/IGF-1R hybrids in the brain. In addition, aged animals demonstrate central insulin resistance, but respond remarkably well to central IGF-1, suggesting that IGF-1 may be a better ligand in the brain than insulin for treating some manifestations of aging. Studies are also ongoing using BOLD-fMRI to assess the impact of central insulin and IGF-1 in the brain as well as with Dr. Young-Hwan Jo on the role of insulin, IGF-1, and their receptors, on electrical activity in specific neuronal populations.

3) Role of obesity and aging on cancer risk â€“ A third area involves the role of aging, obesity and diet on cancer risk. In a pre-clinical model of prostate cancer, we have previously found that cancer risk was linked to energy balance and body mass, but independent of food intake. Likewise, using a surgical model of visceral fat removal, we have found that ablating visceral fat stores in male rats extended their longevity, thus uncoupling the effects of fat from nutrients on lifespan for the first time. More recently, we have found that visceral fat removal is protective from adenoma development and improved survival in a female model of intestinal cancer, providing the first causal evidence linking adiposity to this site-specific cancer. Future areas of interest in this area include studies uncovering the mechanisms behind this link, to determine how abdominal obesity and nutrient availability act independently during the various stages of tumor promotion and progression. We are particularly interested in interrogating the epigenetic changes that occur in specific intestinal stem cells with obesity and aging and how these might relate to later cancer risk. We are also employing parabiosis surgery between young and old animals to assess the role of systemic factors from young and old environments on this process.
