Using Informatics to Improve Data Analysis of Chemical Screening Assays Conducted in Zebrafish
The small size and rapid development of the zebrafish make it a useful vertebrate model for assessing potential effects of chemicals on development in a medium to high-throughput manner. However, a lack of harmonization in several key protocol components hinders the broader adoption of the zebrafish model for toxicological screening. In an effort to address this issue, NTP launched the Systematic Evaluation of the Application of Zebrafish in Toxicology (SEAZIT) program.
SEAZIT is addressing the issues of variability among laboratories in the endpoints measured, as well as the nomenclature used for each endpoint. NICEATM organized a webinar series in support of the SEAZIT program that considered how these issues might be addressed by implementation of standardized nomenclature systems, also known as ontologies.
Webinar 1 (February 2, 2017): Introduction to Zebrafish Screening
This webinar provided an overview of the SEAZIT program and reviewed the variability found in zebrafish screening data.
