Since 2001, we have been developing and expanding the Comparative Toxicogenomics Database (CTD). CTD is a publicly available database that aims to inform understanding about the effects of environmental exposures on human health. To do this, a team of scientists and software developers curate and integrate diverse data describing relationships between chemicals, genes/proteins, phenotypes, and diseases as well as complex exposure information.  Analytical tools are helping scientists in academia, regulatory agencies, and commercial R&D to understand mechanisms of action and biological outcomes of thousands of environmental chemicals and pharmaceutical agents. Meet the CTD team and learn more about this resource through our publications.
