Gene Expression Profiles Perturbed by Injury to the Mouse Intervertebral Disc.
Article in American journal of physical medicine & rehabilitation, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesBack pain subsequent to intervertebral disc injury is a common clinical problem. Previous work examining early molecular changes post injury mainly used a candidate marker approach. In this study, gene expression in the injured and intact mouse tail intervertebral discs was determined with a nonbiased whole transcriptome approach.
designMouse tail intervertebral disc injury was induced by a needle puncture. Whole murine transcriptome was determined by RNASeq. Transcriptomes of injured intervertebral discs were compared with those of intact controls by bioinformatic methods.
resultsAmong the 18,078 murine genes examined, 592 genes were differentially expressed ( P.adj < 0.01). Novel genes upregulated in injured compared with intact intervertebral discs included Chl1, Lum , etc. Ontology study of upregulated genes revealed that leukocyte migration was the most enriched biological process, and network analysis showed that Tnfa had the most protein-protein interactions. Novel downregulated genes in the injured intervertebral discs included 4833412C05Rik , Myoc , etc . The most enriched downregulated pathways were related to cytoskeletal organization.
conclusionsNovel genes highly regulated after disc injury were identified with an unbiased approach; they may serve as biomarkers of injury and response to treatments in future experiments. Enriched biological pathways and molecules with high numbers of connections may be targets for treatments after injury.
