Abstract
Abstract Alcoholic liver disease (ALD) is a consequence of heavy and prolonged alcohol consumptions. We previously demonstrated a hepatic gamma‐aminobutyric acid (GABA) signaling system that protects the liver from toxic injury. The present study was designed to investigate the role of the hepatic GABA signaling system in the process of acute ethanol exposure‐induced liver injury. Our results showed that the expression of GABA synthesizing enzyme glutamic acid decarboxylase and type A GABA receptor (GABA A R) subunits was upregulated in ethanol‐treated mice compared with saline‐treated controls. Remarkably, pretreatment of mice with GABA (1.5 mg kg −1 body weight, intraperitoneal injection [i.p.]) or with the GABA A R agonist muscimol (1.2 mg kg −1 body weight, i.p.) protected the liver against ethanol toxicity and improved liver function, whereas pretreatment of mice with the GABA A R antagonist bicuculline (2.0 mg kg −1 body weight, i.p.) worsened the liver function. Further analyses suggest that GABA A R‐mediated signaling protects the liver from ethanol injury by, at least partially, inhibiting the IRE1α‐ASK1‐JNK pro‐apoptotic pathway in hepatocytes in the process of ethanol‐induced endoplasmic reticulum stress response.

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
