Researchers uncover details about how dietary restriction slows down aging:
Working in yeast cells, the researchers have linked ribosomes, the protein-making factories in living cells, and Gcn4, a specialized protein that aids in the expression of genetic information, to the pathways related to dietary response and aging. The study, which was led by [University of Washington] faculty members Brian Kennedy and Matt Kaeberlein, appears in the April 18 issue of the journal Cell.
