Abstract
Non-alcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome, remains without approved pharmacological treatment. Food-derived bioactive peptides can aid in the management of metabolic conditions including hypertension, obesity and insulin resistance. IRW (isoleucine-arginine-tryptophan) is a tripeptide produced from egg white with angiotensin converting enzyme-inhibitory properties. IRW supplementation elicits antihypertensive effects, improves skeletal muscle insulin signaling and glucose tolerance while reducing body weight gain. In this study, we hypothesized that IRW supplementation would prevent high-fat diet (HFD)-induced NAFLD by modulating hepatic lipid metabolism and increasing mitochondrial content. We found that IRW prevents diet-induced NAFLD, while rosiglitazone (ROSI) treatment worsens it. IRW decreases hepatic triglyceride content and lipid droplet size compared to HFD and ROSI. IRW increases the hepatic mitochondrial complexes and citrate synthase activity, phosphorylation of 5'-AMP-activated protein kinase and microsomal triglyceride transfer protein abundance compared to HFD. Compared with ROSI, IRW increases phosphorylated acetyl CoA carboxylase and mitochondrial complexes. Overall, the hypothesis is supported by these findings.

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
