Universal Mechanisms of Ageing in Metazoans
We are interested in conserved mechanisms that drive the ageing process in animals. Phylogenomic comparisons in our laboratory have yielded the first quantitative trait locus for longevity, as represented by the number of translated cysteine codons (TGT and TGC) in the mitochondrial genome. The coupling of this locus with lifespan was shown to be dependent on aerobic respiration, indicating that cysteine-related redox processes were decisive for longevity. The key redox process to prohibit longevity in animals was subsequently characterised to be the kinetic transfer of sulfur-centered radicals within the inner mitochondrial membrane. Based on these findings, we have developed an amended version of the “Free Radical Theory of Ageing” that integrated many previously contradictory observations, especially the ineffectiveness of antioxidants in intervention studies. We currently investigate unusual chemical and biological strategies to make the elusive sulfur-centered radicals accessible to modulation, with the aim of prolonging life and maintaining health.
