Biological processes and pathway changes in isoflurane-induced anesthesia revealed by bioinformatics analysis of gene expression profiles.
Article in Journal of anesthesia, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo identify differentially expressed genes (DEGs) and further analyze potential biological processes and pathways involved in isoflurane-induced anesthesia.
methodsMicroarray data (ID: GSE64617) from rat brains treated with exposure to either isoflurane in oxygen (2%) (test group) or oxygen alone (control group) for 15 min were downloaded from Gene Expression Omnibus. Data pre-processing was performed using the Affy package, followed by DEG screening using the limma package. Protein-protein interactions (PPIs) among DEGs were obtained from STRING (Search Tool for the Retrieval of Interacting Genes/Proteins), and then visualized by constructing a network using Cytoscape. Functional and pathway enrichment analyses were further implemented to identify the biological processes and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways enriched by DEGs.
resultsA total of 240 DEGs were identified between the test and control groups, including 128 up-regulated DEGs and 112 down-regulated DEGs in the test group, of which 17 DEGs with a connectivity degree >4 were identified as hub genes (e.g., Pik3r1 and Pik3r2) in the constructed PPI network. Additionally, Slc17a7 and Camk4 interacted with Syn1, and Pik3r1 interacted with Pik3r2. Enrichment analysis further revealed the significantly enriched biological processes of 'synaptic transmission', 'cell-cell signaling' and 'transmission of nerve impulse' (e.g., Slc17a7, Camk4, Syn1, Gria1, Prkcg and Lphn1), as well as KEGG pathways including 'focal adhesion', 'Fc γ R-mediated phagocytosis' (e.g., Prkcg, Pik3r1 and Pik3r2), and 'regulation of actin cytoskeleton' (e.g., Pik3r1 and Pik3r2).
conclusionsThe identified DEGs significantly enriched in biological processes and KEGG pathways might be implicated in isoflurane-induced anesthesia.
