Mice also breed quickly, have a short accelerated lifespan, can be kept in defined conditions, and maintained relatively cheaply.
Although research in these areas has mostly focused on Old World primates, such as the rhesus macaque, the common marmoset (Callithrix jacchus), a New World primate, offers important advantages in comparison to other primates, such as an accelerated lifespan.
The persistence of these expression changes would be theoretically easier to demonstrate in humans than mice, as mice have an accelerated lifespan, with 1 mouse year "often equated" to 30 human years.
This accelerated life cycle allows scientists to observe the entire lifespan of the worms.
These small-bodied monkeys have accelerated life histories relative to other primates, reaching reproductive age at approximately 12 18 months of age, and an average captive lifespan of seven years, thus making developmental and longitudinal studies more practicable [ 3].
In congenic females, circulating IGF1 was elevated and as predicted, age of VP was accelerated and lifespan was shortened.
A recently developed mouse model of conditional Sod2 deficiency in connective tissue [ 54] had a reduced lifespan, accelerated aging phenotypes (e.g., weight loss, skin atrophy, kyphosis, osteoporosis, muscle degeneration) and increased cellular senescence by postnatal day 150.
Because blockade of insulin signaling decelerated epidermal aging and a Drosophila lamin mutant with shortened lifespan accelerated epidermal aging, age-related changes in this tissue are analogously regulated by these two established aging pathways.

In fact, hyperactivation of IGF-1R signaling leads to accelerated aging and short lifespan, whereas partial inhibition of IGF-1R delays aging and extends lifespan (Tissenbaum & Guarente, 2002; Kenyon, 2005; Puglielli, 2008; Ungewitter & Scrable, 2008).
Finally, we observed shorter lifespan and accelerated expression of age-related markers in the inbred laboratory strain compared to these wild-derived lines.
