Genetic mutants with daf-10, daf-16 alterations

Names of genes are ordered alphabetically. For the order of interventions, please see the specific paper.

Lifespan (days)

Lifespan change (compared to wild type)
-7.45%
Phenotype
Loss of daf-16 markedly reduced but, in most cases, did not completely eliminate lifespan extension. Thus, most of this lifespan extension requires daf-16 activity, but a fraction is daf-16 independent. daf-16 could act downstream of a sensory signal to regulate lifespan, or it could act in a parallel pathway to provide an activity that these animals simply require for their longevity.
Lifespan comparisons
Double mutant daf-10(m79);daf-16(mu86) has a lifespan of 17.4 days, while single mutant daf-10(m79) has a lifespan of 30.7 days and wild type has a lifespan of 18.8 days.

Abstract
Caenorhabditis elegans senses environmental signals through ciliated sensory neurons located primarily in sensory organs in the head and tail. Cilia function as sensory receptors, and mutants with defective sensory cilia have impaired sensory perception. Cilia are membrane-bound microtubule-based structures and in C. elegans are only found at the dendritic endings of sensory neurons. Here we show that mutations that cause defects in sensory cilia or their support cells, or in sensory signal transduction, extend lifespan. Our findings imply that sensory perception regulates the lifespan of this animal, and suggest that in nature, its lifespan may be regulated by environmental cues.

Intraflagellar transport protein 122 homolog

Locus: CELE_F23B2.4

Wormbase description: daf-10 encodes a WD- and WAA-repeat containing protein that is the C. elegans ortholog of intraflagellar transport (IFT) complex A component IFT122; daf-10 activity is required for intraflagellar transport and thus for proper development of amphid and phasmid neurons, dauer development, chemotaxis, and normal lifespan; a DAF-10::GFP fusion protein undergoes both anterograde and retrograde intraflagellar transport in amphid or phasmid sensory neurons.

Forkhead box protein O;hypothetical protein

Locus: CELE_R13H8.1

Wormbase description: daf-16 encodes the sole C. elegans forkhead box O (FOXO) homologue; DAF-16 functions as a transcription factor that acts in the insulin/IGF-1-mediated signaling (IIS) pathway that regulates dauer formation, longevity, fat metabolism, stress response, and innate immunity; DAF-16 regulates these various processes through isoform-specific expression, isoform-specific regulation by different AKT kinases, and differential regulation of target genes; DAF-16 can interact with the CBP-1 transcription cofactor in vitro, and interacts genetically with other genes in the insulin signaling and with daf-12, which encodes a nuclear hormone receptor; DAF-16 is activated in response to DNA damage during development and co-regulated by EGL-27, alleviates DNA-damage-induced developmental arrest by inducing DAF-16-associated element (DAE)-regulated genes; DAF-16 is broadly expressed but displays isoform-specific tissue enrichment; DAF-16 localizes to both the cytoplasm and the nucleus, with the ratio between the two an important regulator of function.
