Thought the following, reprinted from "Nature"; 397(6718):441-446, might be
of interest to those who think about longevity, and the role that food
might (or might not) play in the lengths of our lifespans.

"Suicidal cells begin killing themselves by activating a series of enzymes
called Caspases. Recent evidence has shown that mitochondria contain
several death factors that activate the caspases and start the rapid
downhill slide. Scientists identified a key mitochondrial death-promoting
protein. In test-tube experiments, the new protein, called
apoptosis-inducing factor, caused the nuclei to chop up their DNA just as
they do in dying cells."

characterization of mitochondrial apoptosis-inducing factor.
