Gene Expression Profiling of Advanced Stage Hepatocellular Carcinoma: A Bioinformatic Analysis.
Article in Asian Pacific journal of cancer prevention : APJCP, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis study aims to examine and explain genetic expression, important genetic markers, and how the immune system interacts with tumors in the advanced stage of hepatocellular carcinoma (HCC).
methodsWe obtained datasets from the Gene Expression Omnibus (GEO) database consisting of 135 HCC patients. Datasets containing at least 100 significant genes determined by volcano plot analysis were utilized. Differentially expressed genes (DEGs) were analyzed by GEO2R. Protein-protein interaction (PPI) networks were built by STRING and Cytoscape. Crucial genes were determined by Network Analyzer and CytoHubba based on four centrality parameters (degree, betweenness, closeness, stress). Gene Ontology, KEGG, and Reactome enrichment analyses were performed to explore the underlying biochemical processes and tumor-immune interaction.
resultWe obtained 3,314 DEGs from two datasets, 75 of which overlapped. The STRING database recognized 63 genes to form PPI (p-value=0.0143). Among them, 13 genes were determined as crucial gene candidates. The action map revealed a significant interaction between 11 of them. Gene enrichment (p-value <0.05) showed biochemical processes involving crucial genes related to advanced-stage HCC, including antioxidant activity, longevity regulating pathways, and reduced oxidized thioredoxin. After enrichment analysis, TXNRD1 and NQO1 were identified as the most crucial genes and may serve as biomarkers and be involved in treatment strategies for patients with advanced-stage liver cancer. Both genes also showed a positive correlation with neutrophil infiltration (p-value <0.001).
conclusionTXNRD1, NQO1, and their related pathways showed potential as biomarkers and therapeutic targets for advanced-stage HCC.
