ready Interaction Ontology

Abbreviation: IxnO

General Information
The Interaction ontology (IxnO) was developed to enable curation of chemical-gene and chemical-protein interactions for the Comparative Toxicogenomics Database (CTD). CTD is a freely available resource that aims to promote understanding and novel hypothesis development about the effects of the environment on human health.

Comparative Toxicogenomics Database
The Comparative Toxicogenomics Database (CTD) advances understanding of the effects of environmental chemicals on human health. Biocurators manually curate chemical-gene, chemical-disease, and gene-disease relationships from the scientific literature. This core data is then internally integrated to generate inferred chemical-gene-disease networks. Additionally, the core data is integrated with external data sets (such as Gene Ontology and pathway annotations) to predict many novel associations between different data types. A unique and powerful feature of CTD is the inferred relationships generated by data integration that helps turn knowledge into discoveries by identifying novel connections between chemicals, genes, diseases, pathways, and GO annotations that might not otherwise be apparent using other biological resources.
