Identification and validation of USP15 and CUL2 as ubiquitination related biomarker in chronic obstructive pulmonary disease.

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
purposeUbiquitination is one of the important epigenetic modifications, influencing the development of various diseases. The objective of this study is to investigate the ubiquitination related genes in chronic obstructive pulmonary disease (COPD).
methodsThe gene microarray dataset from COPD patients and ubiquitination related genes were analyzed. Venn diagram analysis was used to intersect differentially expressed genes and ubiquitination related genes. The functional enrichment analysis of Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Set Enrichment Analysis (GSEA) were performed on differentially expressed ubiquitination related genes. Finally, we confirmed the expression of hub genes through qPCR and western blot experiments in clinical COPD patients and cell lines.
resultsWe identified 2,932 differentially expressed genes and 96 differentially expressed ubiquitination related genes. GO analysis indicated that the differentially expressed ubiquitination related genes were mainly enriched in post-translational protein modification and ubiquitin ligase complex. KEGG analysis showed that ubiquitination related genes were mainly involved in ubiquitin mediated proteolysis and TNF signaling pathway. GSEA analysis suggested that some hub genes are involved in allograft rejection, IL6/JAK/STAT3 signaling and inflammatory response. Our qPCR and western blot experimental results indicate that the expression of USP15 and CUL2 is higher in COPD group compared to the control group, consistent with the bioinformatics analysis.
conclusionOur bioinformatics analysis and experimental results suggest that USP15 and CUL2 may contribute to the progression of COPD through ubiquitination modification. To our knowledge, this is the first study to demonstrate the involvement of USP15 and CUL2 in COPD. Our results may provide new insights into the diagnosis and treatment of COPD.
