Abstract
Our objective was to identify the signaling pathway activated by TSH that induces IL-6 secretion from human abdominal sc differentiated adipocytes. Human abdominal sc preadipocytes in culture were differentiated into adipocytes. IL-6 release stimulated by TSH was inhibited by 35% (P < 0.05) with SN50, an inhibitor of nuclear factor-kappaB (NF-kappaB) nuclear translocation, and 60% (P < 0.01) with sc-514, an inhibitor of inhibitory-kappaB (IkappaB) kinase (IKK)-beta. Phosphorylation of IKKbeta increased upon TSH treatment (10.3-fold, P < 0.01), and IkappaBalpha levels were reduced by 78% (P < 0.01). TSH activated NF-kappaB (23-fold, P < 0.001), a process that was inhibited (60%, P < 0.01) by SN50. Inhibition of protein kinase A by H89 did not affect TSH-stimulated IKKbeta phosphorylation or IkappaBalpha degradation. TSH-mediated NF-kappaB activation and IL-6 induction also specifically occurred in Chinese hamster ovarian cells expressing the human TSH receptor, resulting in a 5.9-fold (P < 0.001) increase in IKKbeta phosphorylation and a 9.5-fold increase in IL-6 mRNA expression. Our data demonstrate that the IKKbeta/NF-kappaB pathway is a novel TSH target that is required for TSH-induced IL-6 release from human 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 it
