Abstract
Identification of the cellular target of small molecules is a major challenge to developing biological tools and drug leads. Here we report a novel microarray-based system for identification of the target or the target pathway of small molecules using a set of drug-hypersensitive fission yeast strains that collectively overexpress each gene in the open reading frame-ome. The major advantage of this method is that it provides genome-wide interrogation but requires a relatively small amount of the test compound. Using this system, we identified 28 genes linked to etoposide sensitivity, which included genes for the drug target topoisomerase II and other plausible factors that regulate etoposide tolerance. Thus, our approach can accelerate the process of target identification of small molecules, which has the potential to reveal highly conserved genes of clinical relevance.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
