News Brief: Tox21 Researchers Publish Analysis of 10,000 Potentially Toxic Chemicals

NCATS robotIn the January 26 issue of Nature Communications, researchers from the Toxicology in the 21st Century (Tox21) program published their first comprehensive analysis from screening a library of more than 10,000 chemicals for toxicity in 30 different human cell–based assays (tests).

Evaluated substances included pesticides, industrial chemicals, food additives and drugs. Using NCATS’ laboratory robots, researchers generated nearly 50 million publicly available data points that can be used to predict the potential effects of chemicals on human biological functions and to enable chemicals to be prioritized for further testing.
