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

backgroundParkinson's disease (PD), a progressive neurodegenerative disease, still lacks disease-modifying treatment strategies. The formation of Lewy body is the typical pathological feature of PD. Pathological progression can be defined by Braak stages. However, the molecular mechanism for this ascending course of α-synuclein pathology remains unclear.

methodsIn this study, weighted gene co-expression network analysis (WGCNA) was used to screen Braak stage-related gene signatures, followed by the functional enrichment analysis, including gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Set Enrichment Analysis (GSEA). The hub genes were screened through CytoHubba and Least Absolute Shrinkage and Selection Operator (LASSO) analysis. The immune cell proportion was predicted by the ImmuCellAI. Furthermore, transcription factors (TFs) and miRNAs targeting the hub genes network were constructed. After verifying hub gene expression level through independent data sets. The validated hub gene was further analyzed to elucidate the potential molecular mechanism.

resultsTotal of 388 genes associated with Braak stages were screened out through WGCNA analysis. The KEGG analysis showed that these genes were involved in endocytosis, HIF-1 signaling pathway, synaptic vesicle cycle, dopaminergic synapse, oxytocin signaling pathway, etc. Immune infiltration analysis showed that CD4 + T cells, including nTreg, Th2, and Th17, were obviously different between different Braak stages in PD. Furthermore, eights Braak stages-related hub genes were identified, including CAMK2B, CPLX2, GAPDH, GRIN1, KCNA1, MAPK3, MAPT, and STXBP1 through the cytoHubba plugin and LASSO analysis. After verifying the expression level in three independent data sets, CPLX2 was finally identified as the most reliable Braak stages-associated hub genes in PD.

conclusionsThis study revealed the Braak stage-related gene signatures in PD and identified CPLX2 as a novel Braak stages-related hub gene in PD, which provided a novel target for future therapeutic interventions and disease markers. The specific molecular mechanism of CPLX2 in PD remained to be further clarified.
