Abstract

Summary: In Caenorhabditis elegans, the forkhead protein DAF‐16 transduces insulin‐like signals that regulate larval development and adult lifespan. To identify DAF‐16‐dependent transcriptional alterations that occur in a long‐lived C. elegans strain, we used cDNA microarrays and genomic analysis to identify putative direct and indirect DAF‐16 transcriptional target genes. Our analysis suggests that DAF‐16 action regulates a wide range of physiological responses by altering the expression of genes involved in metabolism, energy generation and cellular stress responses. Furthermore, we observed a large overlap between DAF‐16‐dependent transcription and genes normally expressed in the long‐lived dauer larval stage. Finally, we examined the in vivo role of 35 of these target genes by RNA‐mediated interference and identified one gene encoding a putative protease that is necessary for the daf‐2 Age phenotype.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
