Abstract
models using clinically related dosages of AS III. Mitophagy, upregulated YAP1 expression, and Nrf2 activation were observed, with upregulation of p62 representing the occurrence of autophagic flux blockade. In HK-2 cells, oxidative stress induced by AS III promoted sustained Nrf2 activation, which enhanced p62 transcription at an early phase. Subsequently, p62 accumulation induced Nrf2 nuclear translocation, which in turn promoted p62 expression, forming a feedback loop to induce autophagic flux blockade, which was aggravated by the autophagic flux blocker chloroquine (CQ). TMP reversed such processes and protected tubular cells, while silencing YAP1 and Nrf2 attenuated TMP renoprotections. YAP1 agonist PY-60 increased Nrf2 expression, while YAP1 knockdown counteracted it and diminished TMP effect on autophagic flux. Furthermore, blocking Nrf2 caused YAP1 accumulation. CO-IP and immunofluorescence co-localization results confirmed co-nuclear translocations of YAP1 bound to dissociated Nrf2 that induced autophagic flux blockade. In conclusion, the present study identified novel mechanisms that TMP alleviated AI-AKI by improving the autophagic flux blockade via a YAP1-Nrf2-p62-dependent mechanism.

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
