Sentence examples for pathways of lifespan from inspiring English sources

However, recent data indicates that there are also Sir2p-independent pathways of lifespan extension [31], [34] and that Sir2p has a pro-aging role in yeast [35], implying that longevity may involve more complex mechanisms than those already known.

Drugs that inhibit the TOR pathway can serve as powerful tools to translate the effects of the TOR pathway on lifespan in simpler invertebrate model systems to more complex systems like mammals.

Using SDC medium, a link between stress resistance and longevity was found and evidence for conservation of pathways modulating lifespan of evolutionally distinct eukaryotes was provided (Fabrizio et al. 2001).

Longevity studies support a role for dPGC-1 as a downstream effector of Indy mutations as shown by overlapping longevity pathways and absence of lifespan extension without wild-type levels of dPGC-1.

In addition, severe CR has been shown to involve the "target of rapamycin" (TOR) pathway for lifespan extension in yeast [12], [13].

Those data prompted Château et al. to address the importance of the FGF Rc pathway for lifespan regulation by CeKL.

These observations suggest that maternal protein restriction can affect major metabolic pathways implicated in regulation of lifespan at a young age which may explain the impact of maternal diet on longevity.

AKT1 can also be activated by TOR complex 2. Previous work on mouse mutants of the IIS and TOR signalling pathways have clearly shown a role for the insulin pathway in the regulation of lifespan, with null S6K (Selman et al., 2009) mice and null IRS-1 (Selman et al., 2008) mice showing significant lifespan extension when compared with wild-type.

The role of the evolutionarily conserved insulin/insulin-like growth factor (IGF-1) signaling (IIS) pathway in the regulation of lifespan is well documented in worms [ 1], flies [ 2], and rodents [ 3, 4].

Among the genes showing the largest and most statistically significant CR-induced expression differences are Ddit4, a key regulator of the TOR pathway, and Nnmt, a regulator of lifespan linked to the sirtuin pathway.

This finding argues that Eps8 does not play a direct role in the classical pathways implicated in the regulation of lifespan [25], and that the longevity phenotype is likely a consequence of the functional CR of these mice.
