LIFE-SPAN Double-Teaming the Aging Process

Two transcription factors that control longevity in the nematode Caenorhabditis elegans code are HSF-1, which is induced by heat stress, and DAF-16, a member of FOXO family. Hsu et al. show that these transcription factors act together to regulate a set of genes, including those for small heat shock proteins (HSPs), which themselves regulate life-span. These small HSPs may counteract aging effects by binding to damaged proteins and preventing the formation of harmful aggregates.
