Abstract
The life span of the nematode Caenorhabditis elegans is under control of sensory signals detected by the amphid neurons. In these neurons, C. elegans expresses at least 13 Galpha subunits and a Ggamma subunit, which are involved in the transduction and modulation of sensory signals. Here, we show that loss-of-function mutations in the Galpha subunits odr-3, gpa-1 and gpa-9, in the Ggamma subunit gpc-1 and the introduction of extra copies of the Galpha subunit gpa-11 extend the life span of C. elegans. Loss-of-function of odr-3 and extra copies of gpa-11 act synergistically and can together extend life span more than two-fold, indicating that sensory signals play an important role in regulating life span. We show that gpa-1, gpa-11, odr-3 and gpc-1 all signal via the daf-16 FOXO family transcription factor. In addition, odr-3 and gpa-11 might suppress life span extension partially independent of the insulin/IGF-1 like receptor homologue daf-2. Our results suggest that the previously unanticipated nociceptive ASH and/or ADL neurons regulate longevity. We expect that the implication of specific G proteins will eventually contribute to the identification of the sensory cues that determine the rate of aging in C. elegans.

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.
