The Adverse Outcome Pathway (AOP) Pathways

This Adverse Outcome Pathway (AOP) Community is created to highlight the molecular basis of AOPs, or events in, AOPS. In general, AOPs start with a Molecular Initiating Event (MIE) caused by a stressor, followed by Key Events (KEs), that lead to an Adverse Outcome (AO). These AOPs are intended specifically for regulatory decision making and are typically stored in the AOP Knowledge Base (AOPKB). Because AOPs are simplified explanations of biological effects after the effect of a stressor they are not useful to describe and understand the molecular basis of the AOPs and not suited to do data analysis. Such analysis is needed especially for in silico risk analysis intending to lower animal use in toxicology studies. This community page was created to present this previously missing molecular level of the AOPs and get more into detail on the biological processes involved in them. The development of these molecular AOPs is relevant for the European research projects on toxicology EU-ToxRisk, OpenRiskNet and VHP4Safety that also funded part of the work. This community page is also featured in the latest NAR Database Issue on WikiPathways.
