Differential regulation of interleukin-1 beta-induced cyclooxygenase-2 gene expression by nimesulide in human synovial fibroblasts.
Bibliographic record
Abstract
Osteoarthritic (OA) human synovial fibroblasts (HSF) in culture were treated with the preferential COX-2 inhibitors nimesulide or NS-398, the non-specific COX-1/COX-2 inhibitor naproxen, or dexamethasone, in the presence or absence of IL-1 beta or LPS. Nimesulide or NS-398 inhibited IL-1 beta-induced PGE2 production at all concentrations tested, and in addition they suppressed IL-1 beta-induced COX-2 mRNA expression and protein synthesis. These suppressive effects were most evident at therapeutic levels of the drugs. Mechanistic studies revealed that the drug-induced inhibition of COX-2 expression and synthesis was not promoter-based, but may be associated with the blockade of IL-1 beta-dependent calcium flux and increased cellular calcium levels.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
