Effects of a Supplementation of n-3 Polyunsaturated Fatty Acids with or without Fish Gelatin on Gene Expression in Peripheral Blood Mononuclear Cells in Obese, Insulin-Resistant Subjects
Bibliographic record
Abstract
AIM: To investigate gene expression changes in peripheral blood mononuclear cells (PBMCs) following an n-3 polyunsaturated fatty acid (PUFA) and n-3 PUFA plus fish gelatin (+FG) supplementation. METHODS: A transcriptome comparison of 8-week supplementation with n-3 PUFA and n-3 PUFA+FG was carried out in PBMCs of 16 obese insulin-resistant subjects. RESULTS: Erythrocyte n-3 PUFA concentration increased and plasma triglycerides decreased significantly without altering inflammatory parameters after both supplementations. n-3 PUFA supplementation changed the expression of 805 genes, whereas n-3 PUFA+FG supplementation altered the expression of 184 genes. Three genes were commonly changed: fatty acid desaturase 1, free fatty acid receptor 3, and ectodysplasin. Pathway analyses indicate changes in gene expression via the nuclear receptor peroxisome proliferator-activated receptor α pathway after both supplementations. Further, the extent of modifications in the expression of genes implicated in the inflammatory pathways - the oxidative stress response mediated by nuclear factor (erythroid-derived 2)-like 2, nuclear transcription factor κB, oxidative stress, and hypoxia-inducible factor signaling - was different after each supplementation. CONCLUSION: Although n-3 PUFA and n-3 PUFA+FG supplementations have a distinct impact on gene expression levels, the consequences on biochemical parameters and metabolic pathways were comparable after both supplementations.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
