Abstract
OBJECTIVES: Previously, we showed that quetiapine, an atypical antipsychotic drug, significantly attenuated neurodegeneration induced by global cerebral ischemia (GCI). The present work investigates the effects of quetiapine on neurogenesis. METHODS: Mice were treated with quetiapine (10 or 20 mg/kg/day; intraperitoneal injection) for 2 weeks and then subjected to GCI on day 15. Seven days after GCI, the mice were killed. Neuronal injury and neurogenesis were analysed using hematoxylin-eosin and 5-bromo-20-deoxyuridine stainings. Levels of nuclear factor kappaB (NF-kappaB) p65/p50 expressions were determined by immunohistochemistry and Western blot analysis. RESULTS: Global cerebral ischemia resulted in neuronal injury, neurogenesis and NF-kappaB p65/p50 expressions in hippocampus, especially in the dentate gyrus. Pre-administration of quetiapine significantly alleviated neuronal injury, while inhibiting neurogenesis and down-regulating NF-kappaB p65/p50 expression. DISCUSSION: NF-kappaB plays a key role in regulating neuron damage and neurogenesis. This work suggests that down-regulation of NF-kappaB expression may be one of the mechanisms by which quetiapine inhibits neurogenesis.

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
