Signaling Proteins that Regulate NaCL Chemotaxis Responses Modulate Longevity in <i>C. elegans</i>
Bibliographic record
Abstract
The lifespan of the nematode Caenorhabditis elegans is regulated by sensory signals detected by the amphid neurons. In these neurons, C. elegans expresses at least 14 Galpha subunits and a Ggamma subunit. We have identified seven sensory Galpha subunits that modulate lifespan. Genetic experiments suggest that multiple sensory signaling pathways exist that modulate lifespan and that some G proteins function in multiple pathways, most of which, but probably not all, involve insulin/IGF-1 like signaling. Interestingly, of the sensory G proteins involved in regulating lifespan, only one Galpha probably functions directly in the detection of sensory cues. The other G proteins seem to function in modulating the sensitivity of the sensory neurons. We hypothesize that in addition to the mere detection of sensory cues, regulation of the sensitivity of sensory neurons also plays a role in the regulation of lifespan.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
