ZEBRAFISH MODELS FOR DRUG DISCOVERY AND GENETIC EPILEPSIES

Tech ID: 25129 / UC Case 2015-026-0

Invention Novelty

Novel Zebrafish epilepsy models carrying the same genetic mutations found in the human population make excellent tools for high-throughput drug screening, in vivo toxicology studies and basic research purposes. 

Value Proposition

There are currently very few animal models for genetic epilepsies or autism spectrum disorders with epilepsy. The few genetically modified rodent models that exist are costly, difficult to develop and not suitable for large-scale drug discovery.  Furthermore, in vitro cultures do not provide the same level of information as in vivo model organisms, particularly in network disorders such as epilepsy or autism. The genetically modified Zebrafish models generated by researchers at the University of California San Francisco (UCSF) provide the following advantages:

            • Low cost approach to in vivo drug screening

            • Rapid proliferation and generation of model organism in a precision medicine manner    

            • Amenable to genetic, behavioral, electrophysiological, imaging and molecular manipulations

Technology Description

Using CRISPR/Cas9 gene editing or ENU-based mutagenesis, researchers at UCSF have created stable transgenic Zebrafish models representing genetic mutations found in children with catastrophic childhood epilepsies and/or autism spectrum disorders with epilepsy. Zebrafish models have been generated and characterized for four genes, with an additional fish under development. To date, over 1300 drugs have been screened using a Zebrafish mutant for Dravet syndrome (scn1 mutation). The ease of generating Zebrafish mutants and a two-stage screening process allow for thorough and rapid drug candidate screening.
