Telomeres and Telomerase: A Modern Fountain of Youth?

Interestingness: 3

By João Pedro de Magalhães and Olivier Toussaint, in Rejuvenation Research, July 2004, 7(2): 126-133. doi:10.1089/1549168041553044.

Not as much new material in this short paper as I expected, probably because I've read quite a bit on the topic since this was published. Interesting bits picked out:
  • No correlation between maximum number of cell replications (cumulative population doublings) and age (post birth). (I have the vague recollection of some paper saying the opposite)
  • No connection between mean telomere length and mammalian aging. (I think they mean across species, the species with the longer telomeres don't live any longer).
  • Telomere length in vivo has very high variability

In summary, they think that telomerase might be beneficial for specific diseases but they doubt it'll turn out to be an anti-aging agent.
