This paper presents a project conducted at Bombardier Aerospace aimed at shortening span time and reducing duplicated effort during design.
However, rapamycin treatment of chico homozygotes, which have more strongly reduced IIS and longer life span than heterozygotes, shortened life span to levels comparable with non-rapamycin-treated controls.
Analysis of the life span of Drosophila C3G deficient adult flies indicates a considerably shortened life span, with a survival rate of 50% after 9 days at 29°C, as compared with 26 days in controls (Figure 2A and B).
However, not every DNA repair deficiency creates exactly the predicted effects; mice deficient in the NER pathway exhibited shortened life span without correspondingly higher rates of mutation.
The loss of Asxl2 activity results in partial embryonic lethality, shortened life span of adult animals, and a reduction in size and body weight.
Notably, dietary restriction shortened life span in more strains than those in which it lengthened life.
Shortened life span of the red blood cells is due to the increased mechanical fragility of the cell membrane.
This leads to accelerated aging and shortened life span due to growth impairment, lipodystrophy, dermal and bone abnormalities, and cardiovascular alterations.
For example, adult-specific over-expression of fruMA and dsxF shortened life span to a similar extent in males and females.
Animals injected with stable PGE2 analog and cAMP phosphodiesterase inhibitor had shortened life span both in the absence and presence of DNR treatment.
Consistent with this idea, we found that the TAp63-/ mice had a significantly shortened life span compared to its wild-type littermates [ 1].
