Abstract
fungus was described. Culture of the isolated specimen led to the extraction of an alkaloid compound, schizocommunin, which was more recently synthesised for biological characterization. Herein we describe schizocommunin and one of its analogues as cytotoxic against human hepatoma cells at low micromolar concentrations. Schizocommunin is shown to be a potent activator of the aryl hydrocarbon receptor (AhR) gene battery, more specifically increasing expression of the CYP1A1, CYP1B1 and UGT1A genes in human liver and lung cells. A luciferase reporter assay further confirms induction of transcription by these compounds at the xenobiotic response element. This study improves our understanding of the interaction between this fungal metabolite and xenobiotic detoxifying mechanisms in the body, and points to schizocommunin as a putative mediator of the allergic response and a useful molecule for the study of the AhR pathway.

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
