This study identifies ANPEP as upregulated in gastric adenocarcinoma and associated with immune suppression and tumor progression, suggesting its potential as a biomarker and therapeutic target.

This study analyzes mutational profiles in gastric adenocarcinoma samples from northern Brazil using NGS, identifying key mutations and patterns associated with replication damage and DNA repair.

This study identifies distinct ferroptosis gene signatures in gastric adenocarcinoma and adjacent tissues, revealing transcriptional heterogeneity and regulatory imbalances.

This study characterizes HERV expression in gastric cancer tissues and finds differential expression in tumor samples, particularly those with H. pylori infection.

The paper identifies viral species in gastric tumor and peritumoral tissues, finding enriched viruses and comparable diversity between tissue types.

This study uses RNA-seq to analyze gene expression in EBV-positive and EBV-negative gastric cancer samples, identifying differentially expressed genes and viral gene activity associated with tumor progression.
