Total lifespan: 147 days.
However, the positive aspects, which include a large CO2 emission reduction aggregated over the lifespan of the farm, outweigh any minor concerns or potential externalities.
Mutants in polarisome components and the myosin V motor protein resulted in reduced efficiency of segregation of protein aggregates and lowered replicative lifespan.
Likewise, larvae brooded by T. coccinea, when kept at high density in still water, could metamorphose and aggregate in clusters with extended lifespan.
In addition, compounds that bind protein aggregates and protect from proteotoxicity increase lifespan (Alavez et al., 2011).
The authors argue that Hsp104 is essential for a normal lifespan, whereas Hsp42, by aggregating misfolded or damaged proteins into the AIDOPOD in the mother, initiates mother/daughter aging asymmetry.
Notably, these animals did not become paralyzed or form myosin aggregates at any point during their lifespan, and their appearance was indistinguishable from that of control animals fed bacteria containing empty vector (Fig. 1B,D,F).
Whereas injection of HSF-1 into an SBMA mouse model resulted in only small effects in neurons, Hsp90/HSPC inhibition by 17-AAG, geranylgeranylacetone (GGA) and geldanamycin (GA) not only substantially increased lifespan, but also diminished aggregates (Fig. 2).
For the lifespan data, we used the pooled aggregate of all of our lifespan data (highlighted rows in Figure 1 source data 1 for wildtype and pooled mutant data in Figure 1 source data 2).
These transgenic rodent models did not show protein aggregates in the CNS during their (median) natural lifespan.
However, the highest aggregating RIL 15 had only intermediate shortening of the lifespan.
