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

Northwest China is the geographic scope for this dataset. It contains integrated transcriptomic and shotgun metagenomic sequencing data from paired tumor and peritumoral mucosal tissues of 88 advanced gastric cancer patients. The dataset was authored by Anqi Wang, shared on figshare under a CC-BY-4.0 license, 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 a focused study.
• Integrates two omics layers (transcriptomics and metagenomics) on paired tissue samples from the same individuals.
• Analysis reveals 8870 differentially expressed genes and 13199 significant host-microbe correlations, indicating a detailed characterization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
• Data is specific to advanced gastric cancer patients from Northwest China, which may limit generalizability.
