Remember, though, that rodent aging is different from most other mammal aging. For one thing, mice aren't affected by telomere replicative senescence (telomerase is not turned off in mouse somatic cells). Cows, whales, primates, horses, etc. all use replicative senescence (presumably for cancer control) and thus are vulnerable to oxidative damage shortening their telomeres. -Bill Content-Type: text/html; charset="US-ASCII" [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=23404
