Abstract
Glycogen synthase kinase-3beta (GSK-3beta)-modulated IFN-gamma-induced inflammation has been reported; however, the mechanism that activates GSK-3beta and the effects of activation remain unclear. Inhibiting GSK-3beta decreased IFN-gamma-induced inflammation. IFN-gamma treatment rapidly activated GSK-3beta via neutral sphingomyelinase- and okadaic acid-sensitive phosphatase-regulated dephosphorylation at Ser(9), and proline-rich tyrosine kinase 2 (Pyk2)-regulated phosphorylation at Tyr(216). Pyk2 was activated through phosphatidylcholine-specific phospholipase C (PC-PLC)-, protein kinase C (PKC)-, and Src-regulated pathways. The activation of PC-PLC, Pyk2, and GSK-3beta was potentially regulated by IFN-gamma receptor 2-associated Jak2, but it was independent of IFN-gamma receptor 1. Furthermore, Jak2/PC-PLC/PKC/cytosolic phospholipase A(2) positively regulated neutral sphingomyelinase. Inhibiting GSK-3beta activated Src homology-2 domain-containing phosphatase 2 (SHP2), thereby preventing STAT1 activation in the late stage of IFN-gamma stimulation. All these results showed that activated GSK-3beta synergistically affected IFN-gamma-induced STAT1 activation by inhibiting SHP2.

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
