The Comparative Toxicogenomics Database (CTD) is a public website and research tool launched in November 2004 that curates scientific data describing relationships between chemicals/drugs, genes/proteins, diseases, taxa, phenotypes, GO annotations, pathways, and interaction modules. The database is maintained by the Department of Biological Sciences at North Carolina State University.

Background

The Comparative Toxicogenomics Database (CTD) is a public website and research tool that curates scientific data describing relationships between chemicals, genes/proteins, diseases, taxa, phenotypes, GO annotations, pathways, and interaction modules, launched on November 12, 2004.[1][2][3][4] The database is maintained by the Department of Biological Sciences at North Carolina State University.[citation needed]

Goals and objectives

One of the primary goals of CTD is to advance the understanding of the effects of environmental chemicals on human health on the genetic level, a field called toxicogenomics.

The etiology of many chronic diseases involves interactions between environmental factors and genes that modulate important physiological processes. Chemicals are an important component of the environment. Conditions such as asthma, cancer, diabetes, hypertension, immunodeficiency, and Parkinson's disease are known to be influenced by the environment; however, the molecular mechanisms underlying these correlations are not well understood. CTD may help resolve these mechanisms. The most up-to-date extensive list of peer-reviewed scientific articles about CTD is available at their publications page[5]

Core data

CTD is a unique resource where biocurators[6][7] read the scientific literature and manually curate four types of core data:

  • Chemical-gene interactions
  • Chemical-disease associations
  • Gene-disease associations
  • Chemical-phenotype associations

Data integration

By integrating the above four data sets, CTD automatically constructs putative chemical-gene-phenotype-disease networks to illuminate molecular mechanisms underlying environmentally-influenced diseases.

These inferred relationships are statistically scored and ranked and can be used by scientists and computational biologists to generate and verify testable hypotheses about toxicogenomic mechanisms and how they relate to human health.

Users can search CTD to explore scientific data for chemicals, genes, diseases, or interactions between any of these three concepts. Currently,[when?] CTD integrates toxicogenomic data for vertebrates and invertebrates.

CTD integrates data from or hyperlinks to these databases:
