The Comparative Toxicogenomics Database (or CTD) is an excellent database to find information on chemical-gene-disease interactions. It is a manually curated database of chemical-gene interactions, chemical-disease and gene-disease associations. At your fingertips you can find information about chemicals, interacting gnees, inferred diseases, pathways, references and news. It’s worth a look. And you can use Google to quickly search the database. Check out this week’s tip to find out more about the database and using Google to search it quickly.
