Integrative analysis of Helicobacter pylori-driven stomach adenocarcinoma reveals epigenetic deregulation, immune evasion, and therapeutic resistance

This study identifies THBS2, CTNNB1, COL4A1, and E2F3 as key H. pylori-associated oncogenic drivers in STAD. Functional assays demonstrate that H. pylori enhance malignant phenotypes through COL4A1 and CTNNB1, while gene silencing reverses these effects. These findings highlight the hub genes and their regulatory miRNAs as promising diagnostic biomarkers and potential therapeutic targets in H. pylori-related gastric cancer.
