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.

  • C. elegans CFAP-20 participates in several sensory and physiological processes that depend on various types of non-motile cilia: gustatory plasticity, lifespan control, locomotion (roaming), and body size determination.

    “Yet, C. elegans CFAP-20 participates in several sensory and physiological processes that depend on various types of non-motile cilia: ability to sense and learn to avoid salt in the absence of food (gustatory plasticity); lifespan control; locomotion (roaming); and, body size determination40,42,47–51.”

    From The inner junction protein CFAP20 functions in motile and non-motile cilia and is critical for vision (2022) · cites this paper as [47]

    The Introduction and the section ‘Multiple sensory G proteins modulate longevity in C. elegans’ discuss sensory cilia, gustatory plasticity, and lifespan control, but do not identify CFAP-20 as participating in them. Searches for CFAP-20, roaming, and body size found no passage connecting that protein to any of the claimed processes. (LLM, conf=0.76)

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.
