Figure Lengend Snippet: A Box plot of USP14 expression levels in the peritumoral tissues (normal) and GC tumors with log-rank test P values < 0.05. B , C Kaplan–Meier analysis of progression-free survival using data from the R2 database and Kaplan-Meier Plotter database. D , E qRT-PCR and Western blot assays were used to detect the expression of USP14 in the human normal gastric cell line (GES-1) and GC cell lines (MKN-45, MGC-803, BGC-823, SGC-7901, HGC-27). F Immunohistochemical staining analysis showed the expression of USP14 in different stages of gastric cancer tissues. Scale bar(black) = 200 μm. Scale bar(red) = 50 μm. All data are expressed as the mean ± SD. Student’s t test was performed to analyze significance. * P < 0.05, ** P < 0.01, *** P < 0.001.

Figure Lengend Snippet: Identification and validation of hub genes in H. pylori-associated stomach adenocarcinoma (STAD). A Differentially expressed genes (DEGs) identified from GSE13911 and GSE54129 datasets. B Venn diagram showing 234 overlapping DEGs shared between the two datasets. C Protein–protein interaction (PPI) network constructed from common DEGs using the STRING database. D Top hub genes ranked by degree centrality using the CytoHubba plugin in Cytoscape. E RT-qPCR validation of hub gene expression in eight gastric cancer cell lines versus five normal gastric epithelial cell lines. F Receiver operating characteristic (ROC) curve analysis showing diagnostic performance (AUC values) of THBS2, CTNNB1, COL4A1, and E2F3 in distinguishing cancerous from normal tissues. P-value < 0.05

Figure Lengend Snippet: Epigenetic regulation and pathway activity of hub genes in STAD. A Promoter methylation levels of THBS2, CTNNB1, COL4A1, and E2F3 in tumor vs. normal tissues using UALCAN database. B Correlation analysis between promoter methylation and gene expression using GSCA database. C Pathway activity profiles showing functional enrichment: THBS2, COL4A1, and E2F3 activate epithelial–mesenchymal transition (EMT) pathways; CTNNB1 is associated with suppression of hormone receptor pathways; E2F3 additionally activates cell cycle-related signalling. P-value < 0.05
