The significant increase in the human life-span during the last century confronts us with great medical challenges. To answer them, one must understand and control the mechanisms that determine healthy ageing. The highly conserved sirtuin deacetylases were shown to regulate life-span in lower organi...

Sirtuins, a family of histone deacetylases, have a fiercely debated role in regulating lifespan of different species. Contrasting recent observations, we here find that overexpression of sir-2.1, the orthologue of mammalian SirT1, does extend C. elegans lifespan. Sirtuins are known to convert NAD+ i...
