Salt‐inducible kinase 1 links p300 phosphorylation to CREB regulated gluconeogenesis post burn
Bibliographic record
Abstract
Severe burn injury results in sustained catecholamine release and increased cyclic AMP (cAMP) levels. cAMP‐induced inhibition of salt‐inducible kinase 1 (SIK1) has been shown to promote recruitment of the transcriptional co‐activator p300 to cAMP response element binding protein (CREB), resulting in gluconeogenesis. Gluconeogenesis is increased and maintained post‐burn injury yet the molecular mechanism is unknown. We hypothesize that catecholamine‐induced inhibition of SIK1 resulting in increased p300 transcriptional activity sustains gluconeogenesis. The 60% total body surface area burn model on rats was employed as a model system. The catecholamine surge during burn injury led to the inhibition of SIK1, increased blood glucose levels, and increased p300 mediated transcription of CREB‐regulated gluconeogenic genes. Restoration of SIK1 activity by administration of propranolol, a non‐selective β1/2 adrenergic receptor antagonist, resulted in inhibition of p300‐ mediated transcription and decreased blood glucose levels. We conclude that catecholamine release after severe burn injury leads to inhibition of SIK1, resulting in sustained gluconeogenesis.

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.
