The Comparative Toxicogenomics Database (CTD) enhanced its data curation by adding a journal-centric approach to its existing chemical-centric method. This new strategy improves data currency and ensures more balanced content on environmental chemical impacts on human health.
Area of Science:
- Toxicology
- Bioinformatics
- Environmental Health
Background:
- The Comparative Toxicogenomics Database (CTD) curates chemical-gene, chemical-disease, and gene-disease interactions from scientific literature.
- CTD traditionally uses a chemical-centric approach for article selection, which can lead to data currency issues.
Purpose of the Study:
- To address data currency challenges, CTD developed and evaluated a complementary journal-centric curation approach.
- To improve the timeliness and balance of curated toxicological data.
Main Methods:
- Identified priority journals based on specific criteria.
- Biocurators reviewed articles from selected journals over a defined period (2009-2011).
- Analyzed curation metrics, including data currency and research topic distribution.
Main Results:
- A journal-centric approach was successfully implemented, complementing the existing chemical-centric method.
- 1252 articles yielded 52,752 curated interactions.
- This method is expected to build more even content and reflect emerging environmental health research areas.
Conclusions:
- The journal-centric approach enhances CTD's ability to maintain current and comprehensive toxicological data.
- This strategy improves data currency and balances the representation of chemicals, genes, and diseases.
- It provides insights into developing areas within environmental health research.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
