CTD turned 10!

The Comparative Toxicogenomics Database (CTD) recently celebrated its 10-year anniversary on the web. Since its beginnings, CTD has been devoted to centralizing and harmonizing information about genes responding to environmental toxic agents across diverse species. The database has now evolved into a premier toxicology resource, allowing scientists to discover information and develop testable hypotheses about the biological consequences of chemical exposure (both environmental and drug). Today, CTD includes over 24 million toxicogenomic connections relating chemicals/drugs, genes/proteins, diseases, taxa, phenotypes, Gene Ontology annotations, and pathways.

This celebratory milestone was recently published in the journal Nucleic Acids Research, which summarized the history and evolution of CTD, including descriptions of curation processes, new content, and enhanced visualization and analysis tools. The article also detailed a new “Pathway View” tool that leverages gene interaction data from BioGRID to allow users to build unique toxicogenomic interaction modules connecting chemical exposure to disease events.

As it was ten years ago, CTD today is still managed by a small team of biologists and software engineers who work with both the toxicology and biocuration communities to advance understanding of chemical-gene-disease data and how best to extract and code this information from the published literature. All CTD data are freely available to the public. As well, CTD content has been disseminated further into the scientific community via more than 55 other databases that routinely incorporate CTD’s annotations.

CTD curates 88K articles for drug-induced events

Understanding chemical toxicity is a common goal shared between environmental health scientists and pharmaceutical drug makers. Now, the Comparative Toxicogenomics Database (CTD, http://ctdbase.org/), which has historically focused on environmental chemicals, has completed a unique curation project coding therapeutic drug-induced disease and phenotype events from more than 88,000 articles published over the last seven decades. The results were recently reported in the journal Database (http://database.oxfordjournals.org/content/2013/bat080.full).

In the study, five CTD biocurators reviewed and manually curated 88,629 articles in just one year, coding information via controlled vocabularies for pharmaceutical compounds and their potential toxicity in cardiovascular, neurological, renal, and hepatic systems. Over 250,000 interactions were ultimately curated, linking 5,500 chemicals, 9,100 genes, 2,700 diseases, and 120 phenotypes. In the paper, CTD provided details about their curation strategy, performance metrics, and enhanced data content. As well, a new module for capturing chemical-phenotype data was introduced to curate drug-induced events at the molecular and cellular level before a disease developed.

One key finding was the discovery of 360 pharmaceutical drugs with overlapping adverse effects for four physiological systems-of-interest to drug makers resulting in cardiotoxicity, neurotoxicity, renal toxicity, and hepatotoxicity. Integrated into the CTD framework, these results are now combined with other datasets to make novel predictions and help generate testable hypotheses about drug-induced events.

The data are freely available from CTD. As well, the curation has been disseminated further into the scientific community via more than 55 other databases that routinely incorporate CTD’s annotations.

DATABASE, The Journal of Biological Databases and Curation, is now the official journal of the International Society for Biocuration.

The International Society for Biocuration (ISB) was created to promote biocuration, the product of multidisciplinary teams of database curators, software developers and bioinformaticians. Biocurators, whose work facilitates research and education across the life sciences, create and maintain a wide variety of online tools and databases essential to the biological community in their daily work. Such important efforts now have a rightful home at DATABASE.

DATABASE, The Journal of Biological Databases and Curation, supports the growing need of the research community to discuss a range of issues related to the creation, development and maintenance of biological databases, and to strengthen communication between database developers, curators and users. As this resonates strongly with the mission of the ISB, we are delighted to announce that DATABASE has now become the Society’s official journal. DATABASE has published more than 250 papers, 50 of which have appeared in the Biocuration Virtual Issue, a special collection of articles describing work presented at the annual International Biocuration Conference.

DORA

The ISB signs the San Francisco Declaration on Research Assessment (DORA), initiated by the American Society for Cell Biology (ASCB) together with a group of editors and publishers of scholarly journals, that aims to improve the ways in which the outputs of scientific research are evaluated.
