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
backgroundGlioblastoma (GBM), a formidable and highly aggressive form of brain cancer, is predominantly driven by GBM stem cells (GSCs), which are characterized by their ability for self-renewal and aberrant differentiation. Targeting the terminal differentiation of GSCs represents a promising therapeutic strategy. This study aimed to elucidate the role of synapsin III (SYN3) in driving the differentiation of GSCs into neuron-like cells and its effect on the tumor-suppressive pathways in GBM.
methodsProliferation assays, limited dilution assays, immunocytochemistry, western blot, RT-qPCR, and GSC tumor models were used to determine gene function and assess the role of γ-secretase inhibitors. Co-immunoprecipitation and microscale thermophoresis were conducted to explore the underlying regulatory mechanisms. Intracranial orthotopic injection of adeno-associated virus (AAV) was performed to evaluate therapeutic potential.
resultsWe demonstrate that SYN3, uniquely within the synapsin family, acts as a tumor suppressor by steering GSCs toward neuronal-like transdifferentiation. Mechanistically, SYN3 enhances the expression of Neuregulin 3 (NRG3), which serves as a non-canonical antagonist of Notch signaling by competitively binding to specific epitopes within the EGF-like domain of JAG1, a critical site for the canonical engagement of Notch receptors. This critical interaction disrupts the JAG1-Notch1 signaling pathway, a key mechanism driving GSCs toward neuronal-like transdifferentiation, thereby reducing their stemness. Furthermore, SYN3 demonstrated significant antineoplastic activity in a mouse model harboring GSCs. AAV-mediated overexpression of SYN3 markedly impeded GBM progression.
conclusionsOur research reveals the therapeutic potential of SYN3 in regulating GSC fate and offers a novel differentiation-based approach for GBM therapy.
