Naked mole-rate - Exploring natural ways to an exceptional long healthspan

The continuous increase in life expectancy and age-related diseases represents an ethical and economic challenge to human society. The project aims to identify molecular networks underlying the exceptional healthy longevity (healthspan) of naked mole-rats. Defying the common trade-off between fecundity and lifespan, reproductive individuals of eusocial species have developed mechanisms resisting ageing. Mole-rats provide a unique opportunity to study the transition of shorter-lived non-breeders into longer-lived breeders. Comparative transcriptomics with free-ranging mole-rats, guinea pigs and mice shall identify underlying genes, subsequently validated in cell culture. Obtained results are aimed at translation into sustained health in an ageing human society.
