Adipose Overexpression of Desnutrin Promotes Fatty Acid Use and Attenuates Diet-Induced Obesity
Bibliographic record
Abstract
OBJECTIVE: To investigate the role of desnutrin in adipose tissue triacylglycerol (TAG) and fatty acid metabolism. RESEARCH DESIGN AND METHODS: We generated transgenic mice overexpressing desnutrin (also called adipose triglyceride lipase [ATGL]) in adipocytes (aP2-desnutrin) and also performed adenoviral-mediated overexpression of desnutrin in 3T3-L1CARDelta1 adipocytes. RESULTS: aP2-desnutrin mice were leaner with decreased adipose tissue TAG content and smaller adipocyte size. Overexpression of desnutrin increased lipolysis but did not result in increased serum nonesterified fatty acid levels or ectopic TAG storage. We found increased cycling between diacylglycerol (DAG) and TAG and increased fatty acid oxidation in adipocytes from these mice, as well as improved insulin sensitivity. CONCLUSIONS: We show that by increasing lipolysis, desnutrin overexpression causes reduced adipocyte TAG content and attenuation of diet-induced obesity. Desnutrin-mediated lipolysis promotes fatty acid oxidation and re-esterification within adipocytes.

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.
