Molecular Insights into the Neurogenic Potential of Alpha-lipoic Acid.

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
introductionAlpha-Lipoic Acid (ALA) is known for its antioxidant and antiinflammatory properties; however, its direct role in neurogenesis remains undefined. This study evaluated the neurogenic potential of the R-enantiomer (R-ALA) using transcriptomic profiling and in vitro validation.
methodsTranscriptome analysis of R-ALA-treated cells was performed to identify differentially expressed genes and enriched pathways. Validation was conducted in different cell lines (C6, PC12, TGW) to assess neurite morphology and neuronal marker expression.
resultsR-ALA induced strong upregulation of several neurogenesis-associated biomarkers and enriched pathways related to neurogenesis, axonogenesis, dendritogenesis, gliogenesis, and neurotransmission (serotonergic, GABAergic). In line with transcriptomic predictions, treated cells exhibited neurite outgrowth and increased expression of neuronal markers, including MAP2, β- tubulin III, NF-200, and GAP43. DISCUSSION: The upregulation of neuron-specific markers and downregulation of progenitorassociated CD44 suggest a comprehensive activation of neuroplastic and regenerative processes, reinforcing ALA's potential as a neurogenic agent.
conclusionThese findings provide the first integrated transcriptome-to-phenotype evidence that R-ALA promotes neurogenesis and neuronal differentiation in vitro, offering a basis for further in vivo exploration in neurodegenerative disorders.
