Defined as a time dependent permanent deformation of materials submitted to loads or strains, creep is generally a unwanted phenomenon, and is frequently a limiting factor regarding a components lifespan [11].
In addition to results demonstrating its function as a pleiotropic aging gene, data from the wild suggest that mth may be an important component in lifespan evolution.
The significance of functional variation at mth is reinforced by the adaptive pattern this allelic variation exhibits among natural populations, and suggests that mth may be an important component in lifespan evolution.
A compelling argument can be made, for example, that autophagy is in an important component of lifespan regulation in all eukaryotes [ 61].
Although genotype was not a significant component of lifespan variance within the diallel, in the introgression experiment, both (C24 x Col) +/+ and (C24 x L er) +/+ lived significantly longer than their parents.
This is a major challenge because the genetic component of lifespan variation in the population at large has been estimated to be only ∼25% (10, 11) and is assumed to be determined by many, still uncharacterized, genes (12, 13).
Somatotropic hormones and their downstream signaling components regulate lifespan in animals (reviewed in Kenyon, 2005, 2010; Berryman et al., 2008).
Fourth, relative measures of TL (corrected for age) correlate with fitness components including lifespan (e.g. [ 11, 15, 17]).
Aging is the result of progressive damage of cellular components throughout the lifespan of an organism.
What's more, the hot, wet and salty environment inside the body can damage electronic components, limiting their lifespan.
