(Submitter supplied) The goal of this experiment was to identify transcripts regulated non-autonomously by age-1 activity in neurons or intestine. Comparisons of gene expression were made between age-1(mg44) null adults and CY251 (age-1(mg44); bvIs2) and CY262 (age-1(mg44); bvIs1); all were relative to wildtype (N2). The integrated transgenes, bvIs2 and bvIs1, carry the age-1 cDNA expressed from the neuronal ric-19 promoter (bvIs2) or intestinal ges-1 promoter (bvIs1). more...

(Submitter supplied) BACKGROUND: When resources are scant, C. elegans larvae arrest as long-lived dauers under the control of insulin/IGF- and TGFbeta-related signaling pathways. : We have identified genes that show different levels of expression in a comparison of wild-type L2 or L3 larvae (non-dauer) to TGFbeta mutants at similar developmental stages undergoing dauer formation. Many insulin/IGF pathway and other known dauer regulatory genes have changes in expression that suggest strong positive feedback by the TGFbeta pathway. more...

(Submitter supplied) The homeostatic maintenance of the genomic DNA is crucial for regulating aging processes. However, the role of RNA homeostasis in aging processes remains unknown. RNA helicases are a large family of enzymes that regulate the biogenesis and homeostasis of RNA. However, the functional significance of RNA helicases in aging has not been explored. Here, we report that a large fraction of RNA helicases regulate the lifespan ofCaenorhabditis elegans. more...

(Submitter supplied) Heat shock factor 1 (HSF-1) and forkhead box O (FOXO) are key transcription factors that protect cells from various stresses. InCaenorhabditis elegans, HSF-1 and FOXO together promote a long life span when insulin/IGF-1 signaling (IIS) is reduced. However, it remains poorly understood how HSF-1 and FOXO cooperate to confer IIS-mediated longevity. Here, we show that prefoldin 6 (PFD-6), a component of the molecular chaperone prefoldin-like complex, relays longevity response from HSF-1 to FOXO under reduced IIS. more...
