Activation of the stress response pathway in young cells extends replicative lifespan, not by reducing global protein synthesis per se, but by Gcn4-mediated autophagy induction.
Genomic associations with lifespan principally reflect heart disease/smoking/dementia but not other cancers, and distinguish lifespan differences of five years between top/bottom deciles of a score derived from DNA alone.
The dramatic extension of lifespan in Sirt6-deficient mice by Trp53 haploinsufficiency suggests that SIRT6 has distinct biological function from SIRT1 in regulating p53 activity and preventing cells from senescence/apoptosis.
A transcriptome-based metric for aging reveals a longevity mechanism that specifically prolongs the duration of young adulthood rather than slowing overall aging.
Longevity in C. elegans is influenced not only by insulin/IGF-1 signalling, but also by CAMKII and calcineurin, acting on the same target, the transcription factor DAF-16.
A robust mouse multi-tissue age predictor is presented that can be used to assess the DNA methylation age of mouse tissues and test the effects of longevity interventions.
Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.
