Recent news about telomere biology and the impact of low-calorie diets on longevity has generated interest in the work of Heidi A. Tissenbaum, PhD, associate professor of molecular medicine. An expert in the genetic mechanisms involved in aging and the signaling pathways that modulate lifespan, Dr. Tissenbaum provided insight on a recent study linking low-calorie diets with longevity and a new test being sold on the United Kingdom that measures a person’s telomere length, a purported indicator of life-span.
Results of Dr. Tissenbaum’s most recently study were published last year in Nature. Read recent coverage: Could 'Extreme' Low-Cal Diets Bring Longer, Healthier Life?
