Control of 4E‐BP1 expression in mouse brown adipose tissue by the β<sub>3</sub>‐adrenoceptor
Bibliographic record
Abstract
Knockout of the translation inhibitor 4E-BP1 induces an overexpression of uncoupling protein-1 (UCP1) [Nature Medicine 7 (2001) 1128]. A possible inverse control of UCP1 and 4E-BP1 expressions in mouse brown adipose tissue was investigated. Cold-exposure, which increases the expression of UCP1, decreased that of 4E-BP1 mRNA in wild type but not in beta1/beta2/beta3-adrenoceptor knockout mice. Administration of the beta3-adrenoceptor agonist CL 316246 decreased 4E-BP1 mRNA by 75% and protein by 41% after 6 and 48 h, respectively. Our data are the first report of a regulation by the beta3-adrenoceptor of 4E-BP1 expression. They support a role of the latter in adaptive thermogenesis.

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.
