Description We have developed several different oestrogen biosensor transgenic zebrafish lines which have great utility for advancing our understandings on adverse impacts of oestrogen on brain development. Newly generated transgenic zebrafish lines are listed under "animal use". We have also developed imaging systems for establishing 4D map of neuronal activity in a whole brain of a live zebrafish embryo using LSM as well as zeiss LSM810 Airyscan and for olfaction-mediated behaviour assay systems. These systems are a valuable resource for use in assessing for adverse effects of environmental pollutants on brain development.
- Significant new resources through the development of a series of new transgenic fish models for studies into chemical, disease and developmental processes and mechanisms ( see Research Tools and Methods).
Exploitation Route Significant new resources through the development of a series of new transgenic fish models for studies into chemical, disease and developmental processes and mechanisms ( see Research Tools and Methods).

By using the CRISPR-mediated gene knock-in method, it is possible to generate more specific genetic mutations in the genome.

All of our new transgenic zebrafish are available for use in the wider research community

Title Application and significant advancement of gene targeting in zebrafish model using CRISPR technology

Impact Significant advancement of gene targeting in zebrafish model using CRISPR technology. Application of CRISPR technology in zebrafish has resulted in evidence supporting roles of specific genes being involved in heart disease in humans and providing new transgenic models for studying effect mechanisms of endocrine active chemicals in fish. Application of CRISPR technology for the gene targeting of a brain specific estrogen synthesising enzyme, Cyp19a1b. Application of CRISPR technology has been used to help identify the roles of a new neural cell type - estrogen receptor olfactory bulb - in the sense of olfaction. 
 
Title CRISPR-mediated gene knock-in method 
Description Recently CRISPR/Cas9 technology has became a very powerful technology by which genomic DNA sequence can be edited to induce genetic mutations (gene knock-out). However, applying this technique to insert an external DNA fragment into a specific genome locus (gene knock-in) is still technically challenging. By using the CRISPR-mediated gene knock-in method, it is possible to generate more specific genetic mutations in the genome (e.g. tissue and stage specific gene mutation, labelling of gene expression using fluorescent protein). To facilitate such technique, we visited Kawahara lab which is one of the world leading research group in developing CRISPR/Cas9 technologies in zebrafish. In Kawahara lab, we tested a few crRNAs to target genomic DNA in zebrafish (targeting GFP gene in fli-GFP transgenic fish, and FGF2 gene in the wild type zebrafish to optimise the experimental conditions) and attempted to knock down the gene as well as to insert mCherry gene into the same targeted locus in the genome. We quantitatively assessed the activities of crRNAs using genomic PCR and confirmed which sequences of crRNAs effectively edited the host genome. Subsequently, the efficiency of gene knock-in was also assessed by PCR and confirmed that the gene insertion of mCherry transgene at in the Cas9 targeted genomic locus of GFP gene in the fli1-GFP transgenic line.

PI Contribution This project has helped to obtain a Japan Partnering Award: Engineering novel transgenic zebrafish with CRISPR/Cas9 technology. At Exeter, we have applied an oestrogen responsive transgenic zebrafish model and also developed new transgenic models to investigate the roles of oestrogen in neurogenesis and brain development, investigating for sex related differences, including in intact animals in real time using advanced imaging methods. Aya Takesono visited our Japanese partner, Professor Atsuo Kawahara (Medical School, Yamanashi University) from 30/July/2017 to 11/Aug/2017. Tetsu Kudoh also visited Kawahara lab from 21st to 31st August 2017. During the visit, Takesono and Kudoh applied novel CRISPR/Cas9 genome editing technology to zebrafish embryo
Collaborator Contribution Through UK-Japan partnerships we are applying CRISPR/Cas9 to produce novel biosensor transgenic fish and gene knock-outs for studies on hormone receptors in zebrafish. This has lead to a new international research partnership with Professor Atsuo Kawahara (Medical School, Yamanashi University).
Impact We have established new transgenic zebrafish lines to elucidate a novel mechanism of action of oestrogen on the forebrain development, in particular, olfactory development. Through this work, we have discovered a new and earliest target of oestrogen in developing zebrafish; glial progenitor cells in the forebrain that exclusively respond to oestrogen (named ER-forebrain cells) and revealed the roles of these ER-forebrain cells in forebrain development and the associated neuronal networks. Further, we have developed several functional assays to assess the developmental roles of ER-forebrain cells, including immunohistochemical analyses for neuronal activation markers, a live imaging for neuronal activation using a genetically encoded calcium indicator GCaMP system and odour-mediated behaviour assays.
