Summary

AOP-Wiki EMOD 3.0, the third evidence model prototype, introduces significant data model expansions and a vision for transforming the AOP-Wiki, the global repository for Adverse Outcome Pathways (AOPs). AOPs are logic models connecting measurable biological mechanisms to adverse outcomes relevant for chemical regulation, contextualizing New Approach Methodologies (NAMs) as alternatives to animal testing. The current AOP-Wiki infrastructure limits its growth, but agentic AI is revitalizing modernization efforts. EMOD 3.0 aims to support computationally-generated AOPs and quantitative AOPs (qAOPs) by improving internal quality, structuring evidence for FAIRness and AI-readiness, and enhancing integration between AOPs and NAMs. This transformation seeks to better serve regulatory science and emergent AOP uses in biomedical and One Health contexts.

Key takeaway

For regulatory scientists and toxicologists evaluating chemical safety, this work highlights how agentic AI can transform data integration and risk assessment. You should consider modernizing your data infrastructure to support computationally-generated Adverse Outcome Pathways (AOPs) and New Approach Methodologies (NAMs). This approach enhances data FAIRness and AI-readiness, improving the efficiency and accuracy of next-generation risk assessments in biomedical and One Health contexts.
