My primary research interest is to understand cell adhesion molecule cadherins function in the development of the vertebrate visual system. I have chosen to study zebrafish, which has become one of the most important animal models for studies of vertebrate development. To study cadherins function in zebrafish visual system development, we first determine their expression using in situ hybridization and/or immunocytochemical methods, followed by disrupting their expression in embryonic zebrafish using antisense morpholino oligonucleotides technology, and finally examine morphological changes in the visual structures and analyze differentiation of retinal and/or tectal neurons using multiple molecular and cellular markers. Our studies have showed that both classical cadherins (e.g. N- and R-cadherins) and protocadherins (e.g. protocadherin-17) play important and differential roles in the zebrafish retinal development.
