We are doing science for policy
The Joint Research Centre (JRC) is the European Commission's science and knowledge service which employs scientists to carry out research in order to provide independent scientific advice and support to EU policy.
Scientists from the JRC and eleven collaborating organisations from the EU, Canada and the USA have shared their collective insights on how adverse outcome pathways (AOP) can aid the development and use of computational prediction models for regulatory toxicology.
The scientists contend that systematically capturing knowledge as AOPs can efficiently inform and help direct the design and development of computational prediction models that can further enhance the utility of data derived from in vitro and in silico methods for toxicological hazard assessment.
The AOP framework provides a systematic approach for managing mechanistic knowledge of toxicological processes associated with potential effects of chemicals on human health and the environment. Computational models of biological systems at various scales provide a means to exploit such understanding to facilitate inference, extrapolation and prediction.
The JRC has also partnered with the OECD and the US Environmental Protection Agency to develop the publically accessible AOP Knowledge Base. This key resource facilitates the scientific crowdsourcing and on-line peer review foreseen in the AOP development process and allows an AOP to continue to evolve as understanding of the underlying science grows. The published article will help the research communities of both predictive toxicology and computational modelling to find common ground, identify synergies and exploit AOP knowledge to advance safety assessment science.
