TCGA-STAD: Differentially Expressed Genes from RNA-Seq Analysis

A list of differentially expressed genes (DEGs) identified from RNA-seq analysis of stomach adenocarcinoma (STAD) samples from The Cancer Genome Atlas (TCGA). The table includes gene symbols and log2 fold change values for 6500 genes. The dataset was authored by Negar Mottaghi-Dastjerdi and last updated on May 21, 2026.

Use Cases

• Identify potential oncogenes or tumor suppressor genes based on log2 fold change values.
• Validate gene expression signatures for stomach adenocarcinoma subtypes.
• Perform pathway enrichment analysis using the list of differentially expressed genes.
• Compare gene expression patterns in TCGA-STAD with other cancer types.

Strengths

• Includes log2 fold change values for 6500 genes, providing a quantitative measure of expression difference.
• Derived from the authoritative TCGA resource, ensuring a standardized source.
• Released under a CC-BY-4.0 license, allowing for broad reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is packaged in a RAR archive, which may require specific software to extract.
