Danggui Shaoyao San Alleviates Early Cognitive Impairment in Alzheimer's Disease Mice Through IRS1/GSK3β/Wnt3a-β-Catenin Pathway.
Article in Brain and behavior, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAlzheimer's disease (AD) is a neurodegenerative disease characterized by Amyloid plaques and neurofibrillary tangles. We explored the potential mechanism by which Danggui Shaoyao San (DSS) modulates central glucose metabolism via the insulin receptor substrate 1 (IRS1)/glycogen synthase kinase-3β (GSK3β)/Wnt3a-β-catenin pathway, thereby exerting protective effects on cognitive functions.
methodsIn vitro, HT22 cells were induced with streptozotocin (STZ) to investigate the impact of GSK3β on pathway transduction. The active components in the DSS stock solution were validated using mass spectrometry. Subsequently, an AD model in C57BL/6J mice was established through STZ injection into both ventricles. The success of the model was validated behaviorally and pathologically. The Morris Water Maze (MWM) test, immunohistochemistry, Western blotting, quantitative reverse transcription-PCR, and 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) were employed to evaluate the influence of DSS on memory and pathological changes in AD.
resultsThe DSS stock solution, rich in active components, ameliorated the memory deficits in AD mice in the MWM. In vitro, GSK3β exhibited regulatory control over Wnt and β-catenin, with GSK3β inhibition mitigating β-amyloid and tau redundancies at protein and gene levels, facilitating signal transduction. In vivo, DSS impacted key targets in the IRS1/GSK3β/Wnt3a-β-catenin pathway, mitigated senile plaques resulting from amyloid β (Aβ) deposition and neurofiber tangles induced by tau hyperphosphorylation, and alleviated the decline in central glucose metabolism observed in FDG-PET.
conclusionsOur findings suggest that DSS potentially confers cognitive protection by alleviating central hypoglycemia through the IRS1/GSK3β/Wnt3a-β-catenin pathway. This may serve as a promising therapeutic avenue for AD.
