Gene expression in a developmentally arrested, long-lived dauer population of Caenorhabditis elegans was compared with a nondauer (mixed-stage) population by using serial analysis of gene expression (SAGE). Dauer (152,314) and nondauer (148,324) SAGE tags identified 11,130 of the predicted 19,100 C. elegans genes. Genes implicated previously in longevity(More)
We have identified longevity-associated genes in a long-lived Caenorhabditis elegans daf-2 (insulin/IGF receptor) mutant using serial analysis of gene expression (SAGE), a method that efficiently quantifies large numbers of mRNA transcripts by sequencing short tags. Reduction of daf-2 signaling in these mutant worms leads to a doubling in mean lifespan. We(More)
genome and that of the nematode Caenorhabditis elegans allows the large-scale identification and analysis of orthologs of human genes in an organism amenable to detailed genetic and molecular analyses. We are determining gene expression profiles in specific cells, tissues, and developmental stages in C. elegans. Our ultimate goal is not only to describe(More)
