Gastric Cancer Multi-Omics Data from 88 Patients in Northwest China

Northwest China data from 88 advanced gastric cancer patients. The dataset contains integrated transcriptomic and shotgun metagenomic sequencing results from paired tumor and peritumoral mucosal tissues, revealing phenotype- and tissue-specific host-microbiota interactions. It was authored by Anqi Wang and last updated on April 20, 2026.

Use Cases

• Identify differentially expressed genes between tumor and peritumoral tissues based on the 8870 DEGs mentioned.
• Analyze correlations between host gene expression and specific bacterial species based on the 13199 significant correlations described.
• Investigate transcriptomic signatures associated with Lauren classification subtypes (intestinal, diffuse, mixed) as detailed in the results.
• Study the impact of Helicobacter pylori infection on host gene expression in peritumoral tissues based on the reported findings.

Strengths

• Includes data from 88 patients, providing a substantial sample size for analysis.
• Integrates two omics layers: transcriptomic and shotgun metagenomic sequencing.
• Focuses on a specific, understudied population from Northwest China.
• Analyzes paired tissue samples (tumor and peritumoral), enabling within-patient comparisons.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Northwest China cohort.
