[extropy-chat] NEWS:Premature ageing secret unlocked

[Joao Magalhaes]

Hi,

It's fun to see that while in Werner's syndrome (WS) cells divide slower 
apparently in Hutchinson-Gilford's syndrome (HGS) they divide faster. Yet I 
think this report misses one important aspect of the study: cells from the 
HGS patients feature a higher rate of apoptosis, just like they do in WS. 
Interestingly, the p66 mutant mice that live 30% longer than controls also 
feature a decrease in apoptosis. What this tells me is that cell turnover 
as a whole appears to play a role in aging, as advocated before.

All the best,

Joao
