Open TG-GATEs API

Open TG-GATES provides gene expression profiles and associated toxicogenomics datasets from 170 compounds to support drug safety assessment and investigation of toxicological mechanisms.

Key Features:

• Extensive Data Collection: Gene expression profiles were generated using RNA microarray technology (Affymetrix) for both rat and human samples.
• Dual-species Coverage: The dataset includes matched rat and human assays to enable cross-species toxicological comparisons.
• Compound Coverage: Data encompass experiments with 170 compounds, primarily pharmaceuticals.
• Comprehensive Metadata: Associated metadata include pathology reports and lot numbers to contextualize experimental results.

Scientific Applications:

• Biomarker Identification: Supports discovery of gene expression signatures that can serve as biomarkers for predicting and evaluating drug safety.
• Toxicological Mechanism Exploration: Enables investigation of molecular responses and toxicological mechanisms of compounds in animal target organs.

Methodology:

The description specifies standardized protocols for sample collection and processing and detailed experimental documentation but does not specify computational preprocessing or analysis methods.
