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

Alpha-synuclein (AS) accumulation is found in the nerve plexuses of the gastrointestinal tract in patients with Parknison's disease (PD). Moreover, alterations in microbiome composition and its metabolites were confirmed in the colon of patients with PD. However, there has been no study that evaluates transcriptomic alterations of the nerve plexus and intestinal epithelium simultaneously using in vivo tissue of patients with PD. Therefore, we aimed to investigate the gene expression profiles of the myenteric plexus and intestinal epithelium of the colon of patients with PD. Ten full-depth slides of paraffin-embedded surgical specimens of the colon or rectum from five patients with PD and five controls were included. AS accumulation was found in the myenteric plexus in all patients with PD. We performed spatial-specific transcriptomic profiling of the myenteric plexus and epithelium using the GeoMX Digital Spatial Profiler. Forty-one differentially expressed genes (DEGs) (36 up-regulated and 5 down-regulated) were identified in the myenteric plexus of patients with PD compared to controls. In the intestinal epithelium, 240 DEGs (81 up-regulated and 159 down-regulated) were identified. Pathway analysis showed upregulated response to type II interferon and lymphocyte activation, while downregulated cellular response to zinc and copper ions in the intestinal epithelium of patients with PD. In the myenteric plexus, neuroepithelial cell differentiation and axon development were upregulated. Network analysis showed the following key genes: and HLA-DRA, SERPINA1, and metallothioneins in the intestinal epithelium, and LAMP1, TUBB2A, and S100B in the myenteric plexus. This study suggests that inflammatory processes may occur in the intestinal epithelium, while neuronal regeneration mechanisms may be active in the myenteric plexus in patients with overtly developed PD. A spatial transcriptomic analysis of the brain and the gastrointestinal tract will enable a better understanding of the gut-brain axis in PD.
