Abstract
Soy proteins are a rich source of various bioactive peptides. LSW (Leu-Ser-Trp) was previously identified from thermolysin-digested soy protein hydrolysate as a potent ACE-inhibitory peptide; however, its biological effects on vascular cells have not been elucidated. The present study evaluated anti-oxidant and anti-inflammatory activities of LSW on vascular smooth muscle cells (VSMCs). Ang II promoted oxidative stress and inflammation in VSMCs; adding LSW did not show anti-oxidant activity, while COX-2, but not iNOS, was down-regulated in Ang II-stimulated VSMCs, suggesting its anti-inflammatory activity. AT1R mediates most of the pathological effects of Ang II in VSMCs; LSW down-regulated Ang II-stimulated AT1R expression, via decreased phosphorylation of both Src and ERK1/2. Furthermore, LSW could also reduce the phosphorylation of nuclear transcription factor p50, but not p65. Results of this study suggested a novel function of LSW as an anti-inflammatory agent on VSMCs, which might broaden its uses as functional food ingredients.

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
