Sirt6 transgene mice

ABSTRACT: 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 organisms. Yet, the role of mammalian sirtuins, SIRT1 to 7, in regulating life-span is currently unclear. Here, we show that in SIRT6 transgenic mice (Sirt6-tg), the males but not the females, have a significant increase in life-span. Gene expression analysis revealed significant differences for male Sirt6-tg in comparison to male wild-type mice. Transgenic males display lower serum IGF-1 levels, increased levels of IGFBP-1 and altered phosphorylation levels of major components of the IGF-1 pathway, a
