Protein Shown to Be Natural Inhibitor of Aging ScienceDaily (Mar. 5, 2010) — Scientists at the University of California, San Diego School of Medicine, have identified a protein called Sestrin that serves as a natural inhibitor of aging and age-related pathologies in fruit flies. They also showed that Sestrin, whose structure and biochemical function are conserved between flies and humans, is needed for regulation of a signaling pathway that is the central controller of aging and metabolism. The work, led by Michael Karin, PhD, Distinguished Professor of Pharmacology in UCSD's Laboratory of Gene Regulation and Signal Transduction, is the cover story of the March 5 issue of the journal Science. |
