'Longevity' gene, diet linked

[Guest guest]

Hello to all,

Here's another article entitled with ties to the one linked to in

post.

From the article:

" In the past, calorie restriction was theorized to be a passive

mechanism, whereby fewer calories reduced metabolism and the

oxidative stresses that come with it. But the discovery that the

protein Sir2—of which SIRT1 is the mammalian orthologue—extends

lifespan in yeast and worms, suggested a more regulated mechanism

involving Sir2. It was not known if this extended to mammals and

SIRT1, and both teams were trying to tackle this question. "

Cheers,
