Description
The main objective of this project is to use a mechanistic framework to develop and propose a high-throughput tiered-testing strategy for screening and prioritizing chemicals for FELS testing (OECD 210). The main objective can be divided into four parts:
- Establish a database of toxicologically relevant FELS-specific AOPs, identify molecular initiating events and subsequent intermediate responses resulting into the apical outcome of interest
- Propose Tier 1 in vitro screening toolbox to test for AOP-specific events and responses predictive for FELS chronic toxicity.
- Propose Tier 2 whole-organism ZFET assays to test for AOP-specific events and responses predictive for FELS chronic toxicity and assess the potential of a ZFET molecular screening tool to predict cellular, organ and/or organism responses giving rise to FELS chronic toxicity.
- Offering a proposal for implementation of a tiered-testing strategy in EU regulation. Assessment of usefulness and applicability of tiered testing strategy for global scientific and regulatory community
