Machine learning-enabled identification of nucleus pulposus senescence-associated genes as potential biomarkers for intervertebral disc degeneration.

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
backgroundIntervertebral disc degeneration (IVDD) has risen to become a global health problem, and its mechanisms are not well understood. The aim of this study was to use machine learning methods to identify key medullary senescence genes associated with IVDD and to further screen for potential biomarkers, as well as to explore the pathways by which these genes can be analyzed in both IVDD and normal states.
methodsGene expression profiles (GSE70362) of IVDD were analyzed from the extensive Gene Expression Omnibus database, and senescence-related genes (SRGs) were obtained from the cell age database. We utilized the Kyoto Encyclopedia of Genes (KEGG) and Gene Ontology (GO) databases for comprehensive functional enrichment analysis. To identify Hub SRDEGs with highly correlated IVDD features (Hub IVDD-SRDEGs), Weighted Gene Co-expression Network Analysis (WGCNA) and two machine learning methods (random forest, and support vector machine recursive feature elimination) were used. Finally, external validation was performed using quantitative polymerase chain reaction (qPCR) and Western blot experiment, and clinic samples validation was also performed using quantitative polymerase chain reaction (qPCR) experiment.
resultsWe discovered 470 DEGs in normal and IVDD nucleus pulposus samples. According to functional enrichment, DEGs are primarily associated with positive regulation of transcription from RNA polymerase II promoter, canonical Wnt signaling pathway, mitotic spindle assembly, response to organic cyclic compound, and cardiac muscle cell apoptotic process. In vivo experiments (qPCR and WB) verified the expression of TAF13 protein. Subsequent qPCR of human nucleus pulposus tissue also showed the same trend of TAF13 gene expression. Hub IVDD-SRDEGs with excellent IVDD diagnostic ability were identified as TAF13.
conclusionsNucleus pulposus aging may promote the progression of IVDD. TAF13 can be used as a novel diagnostic biomolecular marker and for IVDD.
