What is CTD?

The Comparative Toxicogenomics Database (CTD) is a publicly available research resource that curates scientific data describing relationships between chemicals, genes, and human diseases. A primary goal of CTD is to advance the understanding of the effects of environmental chemicals on human health.

CTD is being developed at the North Carolina State University (NCSU). The development team comprises individuals located at NCSU and the Mount Desert Island Biological Laboratory (MDIBL), as well as several biocurators who work remotely.

Data in CTD are provided to enhance knowledge and encourage progress in the scientific community, and are to be used only for research and educational purposes. Any reproduction or use for commercial purpose is prohibited without our prior express written consent.
