Copper Metabolism-Related Genes as Biomarkers in Colon Adenoma and Cancer.
Article in International journal of general medicine, 2025. 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
Purpose: To elucidate the role of copper (Cu) metabolism in the progression of colon adenoma (CA) to colorectal cancer (CRC) and to identify potential biomarkers and therapeutic targets through comprehensive bioinformatics analysis. Patients and Methods: Datasets associated with colon adenoma were retrieved from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) between CA samples and normal controls (NC) were intersected with genes related to copper metabolism (CMRGs) and DEGs between CRC and CA. Five machine-learning algorithms were employed to identify biomarkers. The degree of immune infiltration was evaluated using single-sample Gene Set Enrichment Analysis (ssGSEA), and the expression profiles of these biomarkers across various cell types were further characterized using single-cell RNA sequencing (scRNA-seq). The expression levels of the identified genes were validated using quantitative polymerase chain reaction (qPCR) and data from the Human Protein Atlas (HPA) database. Results: Five biomarkers were identified: ZEB1, ABCA1, SLC24A3, CAV1, and FLNA. Functional enrichment analysis revealed significant pathway alterations in the low-expression groups of CAV1 (eg, phagosome pathway) and FLNA (eg, ribosome pathway). Significant differences in the infiltration abundance of macrophages and mast cells were observed between CA and NC. scRNA-seq analysis demonstrated that these biomarkers were expressed in fibroblasts, lymphocytes, goblet cells, B cells, and macrophages. The consistency of gene expression between patient samples and public datasets was confirmed through qPCR and HPA data. Conclusion: This study explores the role of copper metabolism in colon adenoma progression using bioinformatics. Five genes (ZEB1,ABCA1, SLC24A3, CAV1, FLNA) were identified as potential biomarkers. These genes correlate with immune infiltration and may serve as diagnostic and therapeutic targets. Further clinical validation is needed.
