In new research, Aric N. Rogers, Ph.D., who studies the cellular and molecular mechanisms of aging at the MDI Biological Laboratory in Bar Harbor, Maine, has discovered that muscle may be a protected tissue under conditions of dietary restriction, or DR.
Dietary restriction, in which calories are restricted without malnutrition, is one of the most robust anti-aging interventions. When confronted with a scarcity of nutrients, an organism conserves resources by lowering the translation, or production, of proteins, which is one of the most energetically expensive processes in the cell. Proteins serve as the building blocks for tissues and organs and perform vital physiological functions.
The conservation of cellular resources through red...
