1 · What the graph read from it

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.

2 · The registry

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

backgroundDepression is a multifactorial neuropsychiatric disorder linked to neuroinflammation and epigenetic dysregulation, particularly in histone acetylation. Although magnolol has demonstrated antidepressant-like properties, its precise molecular mechanisms remain unclear. This study aimed to evaluate the antidepressant effects of magnolol and its influence on epigenetic regulation of synaptic plasticity in a chronic unpredictable mild stress (CUMS) mouse model. MATERIAL AND

methodsC57BL/6 mice subjected to CUMS were treated orally with magnolol. Depressive-like behaviors were assessed using standard behavioral tests. Expression levels of histone deacetylase 2 (HDAC2), synaptic proteins such as neuroligin-1 (NLGN1) and neurexin-1β (NRXN1β), and their associated co-localized puncta were examined. Golgi staining and immunofluorescence were performed to assess dendritic spine density and DCX-positive cell population in the hippocampus.

resultsMagnolol treatment alleviated depressive-like behaviors, evidenced by increased sucrose preference and reduced immobility in behavioral assays. It also attenuated hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis, as shown by normalization of serum corticosterone levels and restoration of glucocorticoid receptor (GR) expression in the hippocampal CA1 region. At the molecular level, magnolol reduces HDAC2 expression, which may be associated with altered histone acetylation, thus upregulation of NLGN1 and NRXN1β, enhancing the formation of pre- and postsynaptic co-localized puncta. Additionally, magnolol promoted hippocampal DCX-positive cell population and synaptogenesis, supporting improvements in structural and functional neuroplasticity.

conclusionOur findings demonstrate the ability of magnolol to modulate histone acetylation and synaptic architecture involved in its antidepressant-like action. These results provide a foundation for further exploration of magnolol-based interventions targeting epigenetic and synaptic mechanisms in depression.
