With respect to the molecular, cellular, and integrative traits of aging, N. furzeri shows significant similarities to mammals, including humans.
Both prolong lifespan in many species and retard development of numerous traits of aging [cf. 1- 5 and 6, 7].
By the age of 30 years, 80% of the surviving control macaques showed some traits of aging, whereas in the experimental group such traits were observed in only about 20% of the animals.
In the females, SkQ1 retarded development of such trait of aging as heart mass increase.
For example, SkQ1 prevented the age-dependent disappearance of estrous cycles in females, a typical trait of aging of these animals.
The assumption that aging is favorable for evolvability [ 9, 11, 12, 17] presumes that natural selection fails to eliminate traits of the aging program that increase evolvability but are counterproductive for individuals.
Thus, for example, whereas rapamycin extends lifespan of various organisms including vertebrates [ 16, 78], it does not ameliorate some traits of animal aging [ 79, 80].
Here, we review our current understanding of lncRNAs that control the development of aging traits.
These findings suggest that this variant is not an important contributor to a wide range of aging traits, despite being associated with several cancers (Wang et al., 2008; Rafnar et al., 2009; Stacey et al., 2009; Kohno et al., 2010; Miki et al., 2010; Petersen et al., 2010).
Interlocus sexual conflict has been hypothesized to be an important evolutionary force, potentially affecting the evolution of life-history traits [ 15] and rates of aging [ 16, 17], as well as promoting speciation [ 18- 21].
Iron is known to contribute to ROS production, a hallmark trait of the aging process.
