Accumulation of DNA lesions compromises replication and transcription and is thus toxic to cells. DNA repair deficiencies are generally associated with cellular replicative senescence and premature aging syndromes, suggesting that efficient DNA repair is required for normal longevity. It follows that the evolution of increasing lifespan amongst animal species should be associated with enhanced DNA...
Cellular stress resistance is generally associated with longevity, but the mechanisms underlying this phenotype are not clear. In invertebrate models there is a clear role for heat shock proteins (Hsps) and organelle-specific unfolded protein responses (UPR) in longevity. However, this has not been demonstrated in vertebrates. Some Hsp amino acid sequences are highly conserved amongst mammals and...
Previous studies have shown that longevity is associated with enhanced cellular stress resistance. This observation supports the disposable soma theory of aging, which suggests that the investment made in cellular maintenance will be proportional to selective pressures to extend lifespan. Maintenance of protein homeostasis is a critical component of cellular maintenance and stress resistance. To test...
