Tools to Retrieve relevant AOP information - Holly Mortensen, US Environmental Protection Agency


Published on

This third webinar in the series of Adverse Outcome Pathways (AOPs) was organised on Thursday 30 January 2020. It focused on the core information and telecommunication technologies applications that were built to support AOP development, management and dissemination. Tools and technical tips to facilitate scientific knowledge assembling and evaluations were also presented. The AOP framework implements a collaborative and innovative approach for collecting mechanistic knowledge from various sources that can eventually support chemical safety assessment. Holly Mortensen from the US Environmental Protection Agency presented ways of retrieving information from databases and other AOP tools.

  6. 6. With AOPXplorer you can: - Visualize AOPs from the AOP Ontology - AOP Ontology is a community resource updated with AOPs from the AOP-Wiki and disease pathway information - Perform data analysis in R - Overlay your data with Cytoscape AOPXplorer is looking for new community submissions! 2 routes for submission • Github pull request (clone the repository, add your AOPN as a cytoscape file, make a pull request) op_networks • Email Lyle Burgoon (
  7. 7. Identify tools to link chemicals to AOPs Rycroft et al, ALTEX 2019 Links to publicly available tools, based on four levels of information needed: Step1 INPUT: Uncharacterized Chemical; OUTPUT: six tools to help find MIEs, KEs, or AOs. Step 2: INPUT: Chemical with outcome, no mechanism; OUTPUT: 10 tools to identify chemical analogs Step 3: INPUT: Chemical with some information; OUTPUT: six tools to help find MIEs, KEs, or AOs. Step 4: INPUT: Chemical with single MIE, no biol context; OUTPUT: two tools that identify AOPs from Ste
