Resveratrol: Life extension effects
When an item makes the New York Times, it becomes part of the historical record. In biological sciences, the journal Nature serves a similar purpose. The definitive article on resveratrol’s life extending effects appeared in Nature this month.
Resveratrol improves health and survival of mice on a high-calorie diet

Abstract
Resveratrol (3,5,4′-trihydroxystilbene) extends the lifespan of diverse species including Saccharomyces cerevisiae, Caenorhabditis elegans and Drosophila melanogaster. In these organisms, lifespan extension is dependent on Sir2, a conserved deacetylase proposed to underlie the beneficial effects of caloric restriction. Here we show that resveratrol shifts the physiology of middle-aged mice on a high-calorie diet towards that of mice on a standard diet and significantly increases their survival. Resveratrol produces changes associated with longer lifespan, including increased insulin sensitivity, reduced insulin-like growth factor-1 (IGF-I) levels, increased AMP-activated protein kinase (AMPK) and peroxisome proliferator-activated receptor- coactivator 1
(PGC-1
) activity, increased mitochondrial number, and improved motor function. Parametric analysis of gene set enrichment revealed that resveratrol opposed the effects of the high-calorie diet in 144 out of 153 significantly altered pathways. These data show that improving general health in mammals using small molecules is an attainable goal, and point to new approaches for treating obesity-related disorders and diseases of ageing.
Live Long Enough to Live Forever
I’m in Denver this week and thought I would check out the physician that Ray Kurzweil works with. Ray is a well known and successful serial entrepreneur in the Boston area. Terry Grossman MD is a leading expert on anti-aging and life extension therapies, and the founder and medical director of Frontier Medical Institute in Denver, Colorado. He is the co-author of a new book, Fantastic Voyage: The Science Behind Radical Life Extension. Dr. Grossman’s co-author is the world-renowned inventor and futurist Ray Kurzweil. Fantastic Voyage is the second book written by Dr. Grossman. In 2000, he wrote the well-received Baby Boomers’ Guide to Living Forever. One of the world’s leading proponents of anti-aging medicine, Dr. Grossman strongly believes that humanity stands on the verge of radical increases in longevity. Through his clinical practice in Denver, he has developed numerous protocols for measuring and modifying biological age and promoting longevity.
As medical director of Frontier Medical Institute, he devotes most of his professional time to running his nutritional medicine practice with emphasis on intravenous vitamin and nutritional therapies, as well as anti-aging medicine. He utilizes bio-identical hormone replacement therapy where indicated. In addition, Dr. Grossman is assistant professor of family practice at The University of Colorado School of Medicine.
I got my Ph.D. at the University of Colorado School of Medicine and was an Assistant Professor of Radiology, Preventive Medicine, and Biometrics there for many years. I’ll post a report on the experience after I go through two days of tests. Sort of like the food critic visiting a high class restaurant.
