Giving insight into how chemicals affect our health.
Comparative Toxicogenomics Database

CTD contains curated and inferred chemical–disease associations. Curated chemical–disease associations are extracted from the published literature by CTD curators.

Inferred associations are established via CTD-curated chemical–gene interactions (e.g., chemical A is associated with disease B because chemical A has a curated interaction with gene C, and gene C has a curated association with disease B).

Curated and inferred associations are identified, and help users develop hypotheses about mechanisms underlying environmental diseases. References provide details about the associations.
