Mitochondrial stress signals revise an old aging theory

Cell. 2011 Jan 7;144(1):11-2. doi: 10.1016/j.cell.2010.12.023.

Abstract

In this issue, Durieux et al. (2011) describe a tissue-specific signal, originating from mitochondria, that acts cell non-autonomously to regulate life span in the nematode, C. elegans. This new finding provides a first step toward resolving the relative contributions of mitochondrial free radical damage and signaling mechanisms in aging.
