A screen for genes involved in respiration control and longevity in <i>Schizosaccharomyces pombe</i>
Bibliographic record
Abstract
We present results showing that glucose signaling has proaging effects in the yeast Schizosaccharomyces pombe. Deletion of the receptor that senses extracellular glucose (Git3) increases the life span of S. pombe, while constitutive activation of the Galpha subunit acting downstream of this receptor (Gpa2) shortens its life span. The latter mutant is also impaired for growth under respiration conditions. We have used this phenotype in a selection strategy to identify genes that when overexpressed can rescue the respiratory defect of constitutively active Galpha subunit mutants. Here, we report an extended version of the work we presented at the IABG meeting and the results of this screen. This strategy allowed us to isolate four genes: psp1(+)/moc1(+), cka1(+), adh1(+), and rpb10(+). Interestingly, the overexpression of these genes was also capable of increasing the chronological life span of wild-type yeast cells.

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.
